为更好地理解本公开实施例提供的基于sidelink的通信方法和装置，下面首先对本公开实施例适用的通信系统进行描述。In order to better understand the sidelink-based communication method and device provided by the embodiments of the present disclosure, the communication system to which the embodiments of the present disclosure are applicable is firstly described below.

本公开实施例提供的基于sidelink的通信方法可以应用于图1所示的无线通信系统中。参阅图1所示，该无线通信系统中包括网络设备和终端。终端通过无线资源与网络设备和/或其他终端相连接，并进行数据传输。其中，终端间也可以基于PC5接口进行sidelink通信。可以理解的是，图1所示的无线通信系统仅是进行示意性说明，无线通信系统中还可包括其它网络设备，例如还可以包括核心网设备、无线中继设备和无线回传设备等，在图1中未画出。本公开实施例对该无线通信系统中包括网络设备数量和终端数量不做限定。The sidelink-based communication method provided by the embodiment of the present disclosure may be applied to the wireless communication system shown in FIG. 1 . Referring to FIG. 1 , the wireless communication system includes network devices and terminals.

The embodiment of the present disclosure does not limit the number of network devices and terminals included in the wireless communication system.

进一步可以理解的是，本公开实施例无线通信系统，是一种提供无线通信功能的网络。无线通信系统可以采用不同的通信技术，例如码分多址(code division multipleaccess,CDMA)、宽带码分多址(wideband code division multiple access，WCDMA)、时分多址(time division multiple access，TDMA)、频分多址(frequency division multipleaccess，FDMA)、正交频分多址(orthogonal frequency-division multiple access，OFDMA)、单载波频分多址(single Carrier FDMA，SC-FDMA)、载波侦听多路访问/冲突避免(Carrier Sense MultipleAccess with CollisionAvoidance)。根据不同网络的容量、速率、时延等因素可以将网络分为2G(英文：generation)网络、3G网络、4G网络或者未来演进网络，如5G网络，5G网络也可称为是新无线网络(New Radio，NR)。为了方便描述，本公开有时会将无线通信网络简称为网络。It can be further understood that the wireless communication system in the embodiment of the present disclosure is a network that provides a wireless communication function. The wireless communication system may adopt different communication technologies, such as code division multiple access (CDMA), wideband code division multiple access (WCDMA), time division multiple access (TDMA), Frequency division multiple access (FDMA), orthogonal frequency-division multiple access (OFDMA), single carrier frequency-division multiple access (single Carrier FDMA, SC-FDMA), carrier sense multiple access Access/Conflict Avoidance (Carrier Sense Multiple Access with CollisionAvoidance). According to the capacity, speed, delay and other factors of different networks, the network can be divided into 2G (English: generation) network, 3G network, 4G network or future evolution network, such as 5G network, 5G network can also be called a new wireless network ( New Radio, NR). For convenience of description, the present disclosure sometimes simply refers to a wireless communication network as a network.

进一步的，本公开中涉及的网络设备也可以称为无线接入网设备。该无线接入网设备可以是：基站、演进型基站(evolved node B，基站)、家庭基站、无线保真(wirelessfidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and receptionpoint，TRP)等，还可以为NR系统中的gNB，或者，还可以是构成基站的组件或一部分设备等。应理解，本公开的实施例中，对网络设备所采用的具体技术和具体设备形态不做限定。在本公开中，网络设备可以为特定的地理区域提供通信覆盖，并且可以与位于该覆盖区域(小区)内的终端进行通信。此外，当为车联网(V2X)通信系统时，网络设备还可以是车载设备。Further, the network equipment involved in this disclosure may also be referred to as radio access network equipment. The wireless access network device may be: a base station, an evolved base station (evolved node B, base station), a home base station, an access point (access point, AP) in a wireless fidelity (wirelessfidelity, WIFI) system, and a wireless relay node , a wireless backhaul node, a transmission point (transmission point, TP) or a transmission and reception point (transmission and reception point, TRP), etc., may also be a gNB in an NR system, or may also be a component or a part of equipment constituting a base station. It should be understood that in the embodiments of the present disclosure, no limitation is imposed on the specific technology and specific device form adopted by the network device. In the present disclosure, a network device can provide communication coverage for a specific geographic area, and can communicate with terminals located in the coverage area (cell). In addition, when it is a vehicle-to-everything (V2X) communication system, the network device may also be a vehicle-mounted device.

进一步的，本公开中涉及的终端，也可以称为终端设备、用户设备(UserEquipment，UE)、移动台(Mobile Station，MS)、移动终端(Mobile Terminal，MT)等，是一种向用户提供语音和/或数据连通性的设备，例如，终端可以是具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：智能手机(Mobile Phone)、客户前置设备(Customer Premise Equipment，CPE)，口袋计算机(Pocket Personal Computer，PPC)、掌上电脑、个人数字助理(Personal Digital Assistant，PDA)、笔记本电脑、平板电脑、可穿戴设备、或者车载设备等。此外，当为车联网(V2X)通信系统时，终端设备还可以是车载设备。应理解，本公开实施例对终端所采用的具体技术和具体设备形态不做限定。Further, the terminals involved in this disclosure may also be referred to as terminal equipment, user equipment (User Equipment, UE), mobile station (Mobile Station, MS), mobile terminal (Mobile Terminal, MT), etc. Devices with voice and/or data connectivity, for example, the terminal may be a handheld device, a vehicle-mounted device, etc. with a wireless connection function. Currently, examples of some terminals are: Smartphone (Mobile Phone), Customer Premise Equipment (CPE), Pocket Personal Computer (PPC), PDA, Personal Digital Assistant (PDA) , laptops, tablets, wearable devices, or vehicle-mounted devices, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device may also be a vehicle-mounted device. It should be understood that the embodiment of the present disclosure does not limit the specific technology and specific device form adopted by the terminal.

其中，基站与基站、终端与基站之间的接口可以由LTE、NR等协议规定，终端与终端之间的接口可以由sidelink协议规定，以实现两个终端之间的直连。上文提及，在NR中，特别是通信频段在FR2时，由于高频信道衰减较快，为了保证覆盖范围，需要使用基于波束的发送和接收。为了实现基于波束的传输，就需要进行波束测量。NR中主要是采用SSB和CSI-RS中的至少一项来进行波束测量。Among them, the interface between the base station and the base station, the terminal and the base station can be specified by LTE, NR and other protocols, and the interface between terminals can be specified by the sidelink protocol, so as to realize the direct connection between two terminals. As mentioned above, in NR, especially when the communication frequency band is FR2, due to the fast attenuation of high-frequency channels, in order to ensure coverage, it is necessary to use beam-based transmission and reception. In order to implement beam-based transmission, beam measurements are required. In NR, at least one of SSB and CSI-RS is mainly used for beam measurement.

本公开实施例中，波束是指beam，或称为空间关系信息spatial relationinformation，空间设置spatial setting，空间接收参数Spatial Rx parameter，发送空间滤波器Tx spatial filter，空域接收滤波器spatial domain receive filters，空域发送滤波器spatial domain transmission filter，传输配置指示(TransmissionConfiguration Indication，TCI)状态，准共址(Quasi Co Location，QCL)type D等。In the embodiment of the present disclosure, beam refers to beam, or spatial relation information, spatial setting spatial setting, spatial receiving parameter Spatial Rx parameter, transmitting spatial filter Tx spatial filter, spatial domain receiving filter spatial domain receive filters, spatial domain Transmission filter spatial domain transmission filter, transmission configuration indication (Transmission Configuration Indication, TCI) status, quasi co-location (Quasi Co Location, QCL) type D, etc.

相关技术中，sidelink中没有基于波束的传输，为了引入基于波束的传输，需要设计用于波束测量的参考信号。此时，用于波束测量的参考信号资源该如何配置是需要解决的问题。In the related art, there is no beam-based transmission in the sidelink, and in order to introduce the beam-based transmission, it is necessary to design a reference signal for beam measurement. At this point, how to configure the reference signal resources used for beam measurement is a problem that needs to be solved.

相关技术中，为终端配置的信道状态信息配置(sl-CSI-RS-Config)，包含了一套用于确定起始符号位置的参考信号时域起始符号位置信息(sl-CSI-RS-FirstSymbol)和一套用于确定RE位置和端口数的参考信号频域资源位置(sl-CSI-RS-FreqAllocation)信息，对应一个CSI-RS资源。其中，参考信号时域起始符号位置信息的配置方式如下表1所示。In related technologies, the channel state information configuration (sl-CSI-RS-Config) configured for the terminal includes a set of reference signal time domain start symbol position information (sl-CSI-RS-FirstSymbol ) and a set of reference signal frequency domain resource location (sl-CSI-RS-FreqAllocation) information for determining the RE location and the number of ports, corresponding to one CSI-RS resource. Wherein, the configuration manner of the position information of the start symbol in the time domain of the reference signal is shown in Table 1 below.

表1Table 1

表1示出了一个时隙(slot)内的CSI-RS资源位置。其中，行(row)2对应CSI-RS为1个端口，密度(density)为1是指每个物理资源块(PhysicalResourceBlock，PRB)都有CSI-RS资源的RE。k₀是指CSI-RS占用的PRB中的资源元素(resourceelement，RE)位置，一个PRB包含12个子载波RE。此外，一个PRB包含14个符号，而l₀用于指示CSI-RS资源占用的符号位置。然而，由于对于基于sidelink的通信，终端需要确定出多套参考信号时域起始符号位置信息和参考信号频域资源位置信息来发送对应不同波束方向的多个CSI-RS资源。换言之，对于sidelink中基于波束的传输，上述信道状态信息资源的配置方式并不能直接复用。此外，表1中涉及的“......”表示还有其它数值，这里不一一列出。Table 1 shows the positions of CSI-RS resources in a slot (slot). Wherein, row (row) 2 corresponds to 1 port of CSI-RS, and density (density) of 1 means that each physical resource block (PhysicalResourceBlock, PRB) has REs with CSI-RS resources. k₀ refers to a resource element (resource element, RE) position in a PRB occupied by a CSI-RS, and one PRB includes 12 subcarrier REs. In addition, one PRB contains 14 symbols, and l₀ is used to indicate the symbol position occupied by the CSI-RS resource. However, for sidelink-based communication, the terminal needs to determine multiple sets of reference signal time domain start symbol position information and reference signal frequency domain resource position information to send multiple CSI-RS resources corresponding to different beam directions. In other words, for the beam-based transmission in the sidelink, the configuration method of the above-mentioned channel state information resources cannot be directly multiplexed. In addition, the "..." involved in Table 1 indicates that there are other numerical values, which are not listed here one by one.

鉴于此，本公开提供了一种基于侧链路的通信方法，该方法明确了用于波束测量的参考信号资源的配置，提供了对信道状态信息资源配置的增强方案。在此基础上，终端可以确定用于波束测量的参考信号资源配置信息，进而通过参考信号资源配置信息确定进行sidelink波束测量所对应的参考信号资源信息。In view of this, the present disclosure provides a sidelink-based communication method, which specifies the configuration of reference signal resources for beam measurement, and provides an enhanced scheme for channel state information resource configuration. On this basis, the terminal may determine reference signal resource configuration information for beam measurement, and then determine reference signal resource information corresponding to sidelink beam measurement through the reference signal resource configuration information.

本公开实施例中，可能涉及终端与终端之间的交互。为便于对不同终端进行区分，本公开以下将进行sidelink通信的不同终端称为第一设备和第二设备。图2是根据一示例性实施例示出的一种基于侧链路的通信方法的流程图，如图2所示，基于侧链路的通信方法由第一设备执行，包括以下步骤。In the embodiments of the present disclosure, interaction between terminals may be involved. For the convenience of distinguishing different terminals, in the present disclosure, different terminals performing sidelink communication are referred to as a first device and a second device hereinafter. Fig. 2 is a flowchart showing a communication method based on a side link according to an exemplary embodiment. As shown in Fig. 2 , the communication method based on a side link is executed by a first device, and includes the following steps.

在步骤S11中，确定用于波束测量的参考信号资源配置信息。In step S11, reference signal resource configuration information for beam measurement is determined.

本公开实施例中，参考信号资源配置信息用于确定第一设备进行sidelink波束测量所对应的参考信号资源信息。In the embodiment of the present disclosure, the reference signal resource configuration information is used to determine the reference signal resource information corresponding to the sidelink beam measurement performed by the first device.

第一设备基于确定的参考信号资源配置信息，确定参考信号资源信息，基于参考信号资源信息确定用于波束测量的参考信号资源，进而完成基于参考信号的波束测量。The first device determines reference signal resource information based on the determined reference signal resource configuration information, determines reference signal resources used for beam measurement based on the reference signal resource information, and then completes reference signal-based beam measurement.

示例的，参考信号例如可以包括侧链路信道状态信息(sidelink channel stateinformation reference signal，sidelink CSI-RS)和侧链路同步信号块(sidelink-synchronization signal/physical broadcast channel block，S-SS/PSBCH Block)中的至少一项。Exemplarily, the reference signal may include, for example, sidelink channel state information reference signal (sidelink CSI-RS) and sidelink synchronization signal block (sidelink-synchronization signal/physical broadcast channel block, S-SS/PSBCH Block ) at least one item.

本公开实施例提供的方法，参考信号资源配置信息包括参考信号资源位置信息和参考信号资源集合对应的重复(repetition)状态中的至少一项。In the method provided in the embodiments of the present disclosure, the reference signal resource configuration information includes at least one item of reference signal resource location information and a repetition (repetition) state corresponding to the reference signal resource set.

一示例中，参考信号资源信息包括参考信号资源位置信息。In an example, the reference signal resource information includes reference signal resource location information.

另一示例中，参考信号资源信息包括参考信号资源集合对应的重复状态。In another example, the reference signal resource information includes a repetition state corresponding to the reference signal resource set.

另一示例中，参考信号资源信息同时包括参考信号资源位置信息和参考信号资源集合对应的重复状态。In another example, the reference signal resource information includes reference signal resource location information and a repetition state corresponding to the reference signal resource set.

上述实施例中，参考信号资源集合包括多个参考信号资源，重复状态用于指示多个参考信号资源各自对应的波束是否相同。In the above embodiment, the reference signal resource set includes multiple reference signal resources, and the repetition state is used to indicate whether beams corresponding to the multiple reference signal resources are the same.

示例的，参考信号资源集合对应的重复状态包括开启(on)状态和关闭(off)状态。当参考信号资源集合对应的重复状态为开启(on)状态时，参考信号资源集合内的各个参考信号资源对应同一的波束。当参考信号资源集合对应的重复状态为开启(off)状态时，参考信号资源集合内的各个参考信号资源对应不同的波束。Exemplarily, the repeated states corresponding to the reference signal resource set include an on state and an off state. When the repetition state corresponding to the reference signal resource set is on (on), each reference signal resource in the reference signal resource set corresponds to the same beam. When the repetition state corresponding to the reference signal resource set is an on (off) state, each reference signal resource in the reference signal resource set corresponds to a different beam.

本公开实施例提供的方法，参考信号资源位置信息可以理解为与参考信号的时频资源位置相关的信息。示例的，资源位置信息例如可以包括至少一个时域起始符号位置、至少一个子载波位置、至少一个端口数、参考信号资源数、参考信号资源占用的slot数、参考信号资源占用的小时隙(mini-slot)数、参考信号资源占用的时间单元、参考信号资源占用的起始资源块位置、参考信号资源占用的资源块数量、参考信号资源标识、以及参考信号资源集合标识之一或组合。其中，参考信号资源占用的时间单元可以是slot或mini-slot。其中，mini-slot是相对于以slot为粒度而言。以slot为粒度进行调度时，占用的符号数最小可以为3。以mini-slot为粒度进行调度时，占用的符号数最小可以为1或2。而且一个slot可以包含多个mini-slot的调度单元，一个mini-slot还可以占用两个相邻slot的符号。In the method provided by the embodiments of the present disclosure, the reference signal resource location information may be understood as information related to the time-frequency resource location of the reference signal. Exemplarily, the resource position information may include at least one start symbol position in the time domain, at least one subcarrier position, at least one port number, the number of reference signal resources, the number of slots occupied by reference signal resources, and the small slots occupied by reference signal resources ( mini-slot), the time unit occupied by the reference signal resource, the position of the starting resource block occupied by the reference signal resource, the number of resource blocks occupied by the reference signal resource, the reference signal resource identifier, and one or a combination of reference signal resource set identifiers. Wherein, the time unit occupied by the reference signal resource may be slot or mini-slot. Among them, mini-slot is relative to the granularity of slot. When the slot is used as the granularity for scheduling, the minimum number of occupied symbols can be 3. When scheduling at the granularity of mini-slot, the minimum number of occupied symbols can be 1 or 2. Moreover, a slot can contain multiple mini-slot scheduling units, and a mini-slot can also occupy symbols of two adjacent slots.

本公开实施例提供的方法，资源位置信息可以包括参考信号时域起始符号位置信息(例如sl-CSI-RS-FirstSymbol)，以及包括参考信号频域资源位置信息(例如sl-CSI-RS-FreqAllocation)。其中，sl-CSI-RS-FirstSymbol用于指示参考信号资源对应的时域起始符号位置，sl-CSI-RS-FreqAllocation用于指示参考信号资源对应的RE位置以及端口数。In the method provided by the embodiments of the present disclosure, the resource position information may include reference signal time domain start symbol position information (such as sl-CSI-RS-FirstSymbol), and reference signal frequency domain resource position information (such as sl-CSI-RS-FirstSymbol) FreqAllocation). Wherein, sl-CSI-RS-FirstSymbol is used to indicate the time-domain start symbol position corresponding to the reference signal resource, and sl-CSI-RS-FreqAllocation is used to indicate the RE position and port number corresponding to the reference signal resource.

本公开实施例中，参考信号资源配置信息包括参考信号资源位置信息。一实施方式中，可以通过参考信号资源位置信息配置sl-CSI-RS-FirstSymbol和sl-CSI-RS-FreqAllocation。并且，示例的，资源位置信息可以包括一个或多个sl-CSI-RS-FirstSymbol，以及包括一个或多个sl-CSI-RS-FreqAllocation。In the embodiment of the present disclosure, the reference signal resource configuration information includes reference signal resource location information. In one embodiment, the sl-CSI-RS-FirstSymbol and sl-CSI-RS-FreqAllocation can be configured through reference signal resource location information. And, for example, the resource location information may include one or more sl-CSI-RS-FirstSymbols, and one or more sl-CSI-RS-FreqAllocation.

一实施方式中，资源位置信息包括多个sl-CSI-RS-FirstSymbol以及多个sl-CSI-RS-FreqAllocation。其中，多个sl-CSI-RS-FirstSymbol用于确定多个参考信号资源各自分别对应的时域起始符号位置l，多个sl-CSI-RS-FreqAllocation用于确定多个参考信号资源各自分别对应的RE位置以及端口数。In one embodiment, the resource location information includes multiple sl-CSI-RS-FirstSymbols and multiple sl-CSI-RS-FreqAllocations. Among them, multiple sl-CSI-RS-FirstSymbols are used to determine the time-domain start symbol positions 1 respectively corresponding to multiple reference signal resources, and multiple sl-CSI-RS-FreqAllocation are used to determine multiple reference signal resources respectively Corresponding RE position and number of ports.

其中，多个参考信号资源与多个sl-CSI-RS-FirstSymbol之间是一一对应的关系，多个参考信号资源与多个sl-CSI-RS-FreqAllocation之间也是一一对应的关系。该情况下，相当于为多个参考信号资源中的每个参考信号资源，分别独立配置了sl-CSI-RS-FirstSymbol和sl-CSI-RS-FreqAllocation。也即，为多个参考信号资源中的每个参考信号资源，分别独立配置了时域起始符号位置、RE位置以及端口数。There is a one-to-one correspondence between multiple reference signal resources and multiple sl-CSI-RS-FirstSymbols, and there is also a one-to-one correspondence between multiple reference signal resources and multiple sl-CSI-RS-FreqAllocations. In this case, it is equivalent to configuring sl-CSI-RS-FirstSymbol and sl-CSI-RS-FreqAllocation independently for each of the plurality of reference signal resources. That is, for each reference signal resource among the plurality of reference signal resources, the time-domain start symbol position, RE position, and port number are independently configured.

示例的，终端通过sl-CSI-RS-FirstSymbol来确定时域起始符号位置的方式，可以适用于一个slot包含一个CSI-RS资源的情况，也可以适用于一个slot包含多个CSI-RS资源的情况。在此基础上，为使终端可以进一步明确slot包含CSI-RS资源的具体情况，可使用资源位置信息，通过显式指示方式或默认规则，对slot包含CSI-RS资源的情况做出指示。For example, the way the terminal uses sl-CSI-RS-FirstSymbol to determine the position of the start symbol in the time domain can be applied to the case where a slot contains one CSI-RS resource, or it can be applied to a slot containing multiple CSI-RS resources Case. On this basis, in order to enable the terminal to further clarify the specific situation that the slot contains CSI-RS resources, the resource location information can be used to indicate the situation that the slot contains CSI-RS resources through an explicit indication method or a default rule.

一示例中，可以通过资源位置信息指示每个CSI-RS资源对应的slot位置，相当于资源以显式指示方式对slot包含CSI-RS资源的情况进行了指示。在此基础上，资源位置信息可以用于确定多个参考信号资源各自分别对应的slot位置，第一设备可基于资源位置信息确定每个CSI-RS资源对应的slot位置。In an example, the slot position corresponding to each CSI-RS resource may be indicated through the resource position information, which is equivalent to the fact that the resource indicates that the slot contains the CSI-RS resource in an explicit manner. On this basis, the resource location information may be used to determine slot locations corresponding to the multiple reference signal resources, and the first device may determine the slot location corresponding to each CSI-RS resource based on the resource location information.

另一示例中，可以通过资源位置信息对CSI-RS资源所占用的时间单元做出指示。例如，资源位置信息可以用于指示多个参考信号资源占用的slot数。在此基础上，资源位置信息可以用于确定多个参考信号资源占用的slot数，第一设备可基于资源位置信息确定多个参考信号资源占用的slot数。此外，资源位置信息还可以用于指示多个参考信号资源占用的mini-slot数。在此基础上，资源位置信息可以用于确定多个参考信号资源占用的mini-slot数，第一设备可基于资源位置信息确定多个参考信号资源占用的mini-slot数。In another example, the time unit occupied by the CSI-RS resource may be indicated through resource location information. For example, the resource location information may be used to indicate the number of slots occupied by multiple reference signal resources. On this basis, the resource location information may be used to determine the number of slots occupied by multiple reference signal resources, and the first device may determine the number of slots occupied by multiple reference signal resources based on the resource location information. In addition, the resource location information may also be used to indicate the number of mini-slots occupied by multiple reference signal resources. On this basis, the resource location information may be used to determine the number of mini-slots occupied by multiple reference signal resources, and the first device may determine the number of mini-slots occupied by multiple reference signal resources based on the resource location information.

其中，不同参考信号资源可以对应相同或不同的slot位置。Wherein, different reference signal resources may correspond to the same or different slot positions.

例如，当资源位置信息用于确定多个参考信号资源各自分别对应的slot位置时，对于对应相同slot位置的参考信号资源而言，不同参考信号资源对应的时域起始符号位置需要不同。而对于对应不同slot位置的参考信号资源而言，不同参考信号资源对应的时域起始符号位置可以相同或不同。又例如，当资源位置信息用于确定多个参考信号资源占用的slot数时，不同CSI-RS资源对应的slot不同。又例如，当资源位置信息用于确定多个参考信号资源占用的mini-slot数时，资源位置信息指示基于mini-slot的传输，不同CSI-RS资源对应的slot可以相同或不同。For example, when the resource position information is used to determine slot positions corresponding to multiple reference signal resources, for reference signal resources corresponding to the same slot position, the time-domain start symbol positions corresponding to different reference signal resources need to be different. For reference signal resources corresponding to different slot positions, the time-domain start symbol positions corresponding to different reference signal resources may be the same or different. For another example, when the resource location information is used to determine the number of slots occupied by multiple reference signal resources, the slots corresponding to different CSI-RS resources are different. For another example, when the resource location information is used to determine the number of mini-slots occupied by multiple reference signal resources, the resource location information indicates mini-slot-based transmission, and slots corresponding to different CSI-RS resources may be the same or different.

本公开实施例提供的方法，参考信号可以是sidelink CSI-RS。以sidelink CSI-RS为例，后续我们简称为CSI-RS。每个CSI-RS资源需要占用M个符号位，且CSI-RS资源前需要配置自动增益控制(automatic gain control，AGC)调整，需要在CSI-RS资源所占用的符号位前额外占用用于AGC的一个符号位。换言之，对于一个CSI-RS资源的配置，需要占用M+1个符号位。此外，slot本身需要预留一个符号为gap，因此，当一个CSI-RS资源的配置需要M个符号位且M＝1时，且slot支持配置的符号位数为N(示例的，N为正整数)时，一个slot可配置的CSI-RS资源的数量为N/2-1。例如，当slot支持12个符号位的配置时，一个slot可以包含最多5个CSI-RS资源。当slot支持14个符号位的配置时，一个slot可以包含最多6个CSI-RS。当一个slot的符号位被占满时，配置后续的CSI-RS资源配置时，则继续占用连续slot中的下一个slot。In the method provided by the embodiments of the present disclosure, the reference signal may be a sidelink CSI-RS. Taking sidelink CSI-RS as an example, we will refer to it as CSI-RS for short. Each CSI-RS resource needs to occupy M sign bits, and automatic gain control (automatic gain control, AGC) adjustment needs to be configured before the CSI-RS resource, and it needs to be additionally occupied before the sign bit occupied by the CSI-RS resource for AGC A sign bit of . In other words, for the configuration of one CSI-RS resource, M+1 sign bits need to be occupied. In addition, the slot itself needs to reserve a symbol as a gap. Therefore, when the configuration of a CSI-RS resource requires M sign bits and M=1, and the number of sign bits supported by the slot is N (in the example, N is positive integer), the number of configurable CSI-RS resources for one slot is N/2-1. For example, when the slot supports the configuration of 12 sign bits, a slot can contain up to 5 CSI-RS resources. When the slot supports the configuration of 14 sign bits, a slot can contain a maximum of 6 CSI-RSs. When the sign bit of a slot is fully occupied, when configuring the subsequent CSI-RS resource configuration, continue to occupy the next slot in the continuous slots.

一实施方式中，资源位置信息包括多个sl-CSI-RS-FirstSymbol以及单一sl-CSI-RS-FreqAllocation。其中，多个sl-CSI-RS-FirstSymbol用于确定多个参考信号资源各自分别对应的时域起始符号位置，单一sl-CSI-RS-FreqAllocation用于确定多个参考信号资源对应的RE位置以及端口数。In one embodiment, the resource location information includes multiple sl-CSI-RS-FirstSymbols and a single sl-CSI-RS-FreqAllocation. Among them, multiple sl-CSI-RS-FirstSymbols are used to determine the time-domain start symbol positions corresponding to multiple reference signal resources, and a single sl-CSI-RS-FreqAllocation is used to determine the RE positions corresponding to multiple reference signal resources and the number of ports.

其中，多个参考信号资源与多个sl-CSI-RS-FirstSymbol之间是一一对应的关系。该情况下，相当于为多个参考信号资源中的每个参考信号资源，分别独立配置了sl-CSI-RS-FirstSymbol，且不同参考信号资源相比，时域起始符号位置可以相同或不同。此外，资源位置信息还包括用于确定多个参考信号资源对应RE位置以及端口数的单一sl-CSI-RS-FreqAllocation，该单一sl-CSI-RS-FreqAllocation可以理解为多个参考信号资源共用的sl-CSI-RS-FreqAllocation。换言之，多个参考信号资源各自对应了同样的sl-CSI-RS-FreqAllocation。该情况下，每个参考信号资源对应的RE位置和端口数是一样的。There is a one-to-one correspondence between multiple reference signal resources and multiple sl-CSI-RS-FirstSymbols. In this case, it is equivalent to configuring sl-CSI-RS-FirstSymbol independently for each of the multiple reference signal resources, and compared with different reference signal resources, the position of the start symbol in the time domain can be the same or different . In addition, the resource location information also includes a single sl-CSI-RS-FreqAllocation for determining the RE location and the number of ports corresponding to multiple reference signal resources. The single sl-CSI-RS-FreqAllocation can be understood as a shared sl-CSI-RS-FreqAllocation. In other words, the multiple reference signal resources each correspond to the same sl-CSI-RS-FreqAllocation. In this case, the RE positions and port numbers corresponding to each reference signal resource are the same.

示例的，终端通过sl-CSI-RS-FirstSymbol来确定时域起始符号位置的方式，可以适用于一个slot包含一个CSI-RS资源的情况，也可以适用于一个slot包含多个CSI-RS资源的情况。在此基础上，为使终端可以进一步明确slot包含CSI-RS资源的具体情况，可使用资源位置信息，通过显式指示方式或默认规则，对slot包含CSI-RS资源的情况做出指示。其中，由于通过资源位置信息指示CSI-RS资源所占用的时间单元的实现方式，本公开上述实施例中已经进行了说明，因此具体实现方式可直接参考上述实施例，本公开在此不做赘述。For example, the way the terminal uses sl-CSI-RS-FirstSymbol to determine the position of the start symbol in the time domain can be applied to the case where a slot contains one CSI-RS resource, or it can be applied to a slot containing multiple CSI-RS resources Case. On this basis, in order to enable the terminal to further clarify the specific situation that the slot contains CSI-RS resources, the resource location information can be used to indicate the situation that the slot contains CSI-RS resources through an explicit indication method or a default rule. Wherein, since the implementation of indicating the time unit occupied by the CSI-RS resources through the resource location information has been described in the above-mentioned embodiments of the present disclosure, the specific implementation may directly refer to the above-mentioned embodiments, and the present disclosure will not repeat them here. .

一实施方式中，资源位置信息包括单一sl-CSI-RS-FirstSymbol以及多个sl-CSI-RS-FreqAllocation。其中，单一sl-CSI-RS-FirstSymbol用于确定多个参考信号资源对应的时域起始符号位置，多个sl-CSI-RS-FreqAllocation用于确定多个参考信号资源各自分别对应的RE位置以及端口数。In one embodiment, the resource location information includes a single sl-CSI-RS-FirstSymbol and multiple sl-CSI-RS-FreqAllocations. Among them, a single sl-CSI-RS-FirstSymbol is used to determine the time-domain start symbol positions corresponding to multiple reference signal resources, and multiple sl-CSI-RS-FreqAllocation are used to determine the RE positions corresponding to multiple reference signal resources respectively and the number of ports.

例如，资源位置信息包括单一sl-CSI-RS-FirstSymbol以及多个sl-CSI-RS-FreqAllocation。其中，多个参考信号资源中不同参考信号资源对应相同时域起始符号位置。而多个参考信号资源与多个sl-CSI-RS-FreqAllocation之间是一一对应的关系，相当于为多个参考信号资源中的每个参考信号资源，分别独立配置了sl-CSI-RS-FreqAllocation。也即，为多个参考信号资源中的每个参考信号资源，分别独立配置了RE位置以及端口数。此时，不同CSI-RS资源对应不同slot，但对应相同时域起始符号位置。并且，不同CSI-RS资源对应的RE位置和端口数可以相同或不同。For example, the resource location information includes a single sl-CSI-RS-FirstSymbol and multiple sl-CSI-RS-FreqAllocations. Wherein, different reference signal resources among the multiple reference signal resources correspond to the same time-domain start symbol position. There is a one-to-one correspondence between multiple reference signal resources and multiple sl-CSI-RS-FreqAllocations, which is equivalent to independently configuring sl-CSI-RS for each of the multiple reference signal resources. -FreqAllocation. That is, for each reference signal resource among the plurality of reference signal resources, the position of RE and the number of ports are independently configured. At this time, different CSI-RS resources correspond to different slots, but correspond to the same start symbol position in the time domain. In addition, RE positions and port numbers corresponding to different CSI-RS resources may be the same or different.

例如，资源位置信息包括单一sl-CSI-RS-FirstSymbol以及多个sl-CSI-RS-FreqAllocation，并包括slot数量和/或参考信号资源数量。其中，多个参考信号资源中不同参考信号资源对应相同时域起始符号位置。而多个参考信号资源与多个sl-CSI-RS-FreqAllocation之间是一一对应的关系，相当于为多个参考信号资源中的每个参考信号资源，分别独立配置了sl-CSI-RS-FreqAllocation。也即，为多个参考信号资源中的每个参考信号资源，分别独立配置了RE位置以及端口数。此时，不同CSI-RS资源对应不同slot，但对应相同时域起始符号位置。并且，不同CSI-RS资源对应的RE位置和端口数可以相同或不同。For example, the resource location information includes a single sl-CSI-RS-FirstSymbol and multiple sl-CSI-RS-FreqAllocations, and includes the number of slots and/or the number of reference signal resources. Wherein, different reference signal resources among the multiple reference signal resources correspond to the same time-domain start symbol position. There is a one-to-one correspondence between multiple reference signal resources and multiple sl-CSI-RS-FreqAllocations, which is equivalent to independently configuring sl-CSI-RS for each of the multiple reference signal resources. -FreqAllocation.

At this time, different CSI-RS resources correspond to different slots, but correspond to the same start symbol position in the time domain. In addition, RE positions and port numbers corresponding to different CSI-RS resources may be the same or different.

又例如，资源位置信息包括单一sl-CSI-RS-FirstSymbol以及多个sl-CSI-RS-FreqAllocation。其中，多个参考信号资源与多个sl-CSI-RS-FreqAllocation之间是一一对应的关系，相当于为多个参考信号资源中的每个参考信号资源，分别独立配置了sl-CSI-RS-FreqAllocation。也即，为多个参考信号资源中的每个参考信号资源，分别独立配置了RE位置以及端口数，不同CSI-RS资源对应的RE位置和端口数可以相同或不同。并且，多个参考信号资源中不同参考信号资源对应的时域起始符号位置为首个mini-slot所对应符号位置，多个mini-slot中相邻mini-slot之间具有设定数量符号间隔，且不同参考信号资源对应相同或不同的RE位置和端口数。For another example, the resource location information includes a single sl-CSI-RS-FirstSymbol and multiple sl-CSI-RS-FreqAllocations. Among them, there is a one-to-one correspondence relationship between multiple reference signal resources and multiple sl-CSI-RS-FreqAllocations, which is equivalent to independently configuring sl-CSI-RS-FreqAllocation for each of the multiple reference signal resources.

That is, for each reference signal resource among the plurality of reference signal resources, RE positions and port numbers are configured independently, and the RE positions and port numbers corresponding to different CSI-RS resources may be the same or different. In addition, the time-domain starting symbol positions corresponding to different reference signal resources in the multiple reference signal resources are the symbol positions corresponding to the first mini-slot, and there is a set number of symbol intervals between adjacent mini-slots in the multiple mini-slots, And different reference signal resources correspond to the same or different RE positions and port numbers.

又例如，资源位置信息包括单一sl-CSI-RS-FirstSymbol以及多个sl-CSI-RS-FreqAllocation，并包括mini-slot数量和/或参考信号资源数量。其中，多个参考信号资源与多个sl-CSI-RS-FreqAllocation之间是一一对应的关系，相当于为多个参考信号资源中的每个参考信号资源，分别独立配置了sl-CSI-RS-FreqAllocation。也即，为多个参考信号资源中的每个参考信号资源，分别独立配置了RE位置以及端口数，不同CSI-RS资源对应的RE位置和端口数可以相同或不同。并且，多个参考信号资源中不同参考信号资源对应的时域起始符号位置为首个mini-slot所对应符号位置，多个mini-slot中相邻mini-slot之间具有设定数量符号间隔，且不同参考信号资源对应相同或不同的RE位置和端口数。For another example, the resource location information includes a single sl-CSI-RS-FirstSymbol and multiple sl-CSI-RS-FreqAllocations, and includes the number of mini-slots and/or the number of reference signal resources. Among them, there is a one-to-one correspondence relationship between multiple reference signal resources and multiple sl-CSI-RS-FreqAllocations, which is equivalent to independently configuring sl-CSI-RS-FreqAllocation for each of the multiple reference signal resources. RS-FreqAllocation. That is, for each reference signal resource among the plurality of reference signal resources, RE positions and port numbers are configured independently, and the RE positions and port numbers corresponding to different CSI-RS resources may be the same or different. In addition, the time-domain starting symbol positions corresponding to different reference signal resources in the multiple reference signal resources are the symbol positions corresponding to the first mini-slot, and there is a set number of symbol intervals between adjacent mini-slots in the multiple mini-slots, And different reference signal resources correspond to the same or different RE positions and port numbers.

示例的，参考信号可以是sidelink CSI-RS。以sidelink CSI-RS为例，后面简称CSI-RS。每个CSI-RS资源需要占用M个符号位，且CSI-RS资源前需要配置自动增益控制(automatic gain control，AGC)调整，需要在CSI-RS资源所占用的符号位前额外占用用于AGC的一个符号位。换言之，对于一个CSI-RS资源的配置，需要占用M+1个符号位。此外，slot本身需要预留一个符号为gap，因此，当一个CSI-RS资源的配置需要占用M+1个符号位且M＝1时，且slot支持配置的符号位数为N(示例的，N为正整数)时，一个slot可配置的CSI-RS资源的数量为N/2-1。例如，当slot支持12个符号位的配置时，一个slot可以包含最多5个CSI-RS资源。当slot支持14个符号位的配置时，一个slot可以包含最多6个CSI-RS资源。当一个slot的符号位被占满时，配置后续的CSI-RS资源配置时，则继续占用连续slot中的下一个slot。Exemplarily, the reference signal may be a sidelink CSI-RS. Take sidelink CSI-RS as an example, hereinafter referred to as CSI-RS. Each CSI-RS resource needs to occupy M sign bits, and automatic gain control (automatic gain control, AGC) adjustment needs to be configured before the CSI-RS resource, and it needs to be additionally occupied before the sign bit occupied by the CSI-RS resource for AGC A sign bit of . In other words, for the configuration of one CSI-RS resource, M+1 sign bits need to be occupied. In addition, the slot itself needs to reserve a symbol as a gap. Therefore, when the configuration of a CSI-RS resource needs to occupy M+1 symbol bits and M=1, and the number of symbol bits supported by the slot is N (for example, When N is a positive integer), the number of CSI-RS resources that can be configured in one slot is N/2-1. For example, when the slot supports the configuration of 12 sign bits, a slot can contain up to 5 CSI-RS resources. When the slot supports the configuration of 14 sign bits, one slot can contain a maximum of 6 CSI-RS resources. When the sign bit of a slot is fully occupied, when configuring the subsequent CSI-RS resource configuration, continue to occupy the next slot in the continuous slots.

当然，参考信号资源占用一个符号位仅是一可行实施例，参考信号资源实际占用的符号数并不限于此。相应的，对于一个slot而言，其可支持的参考信号资源的配置数量，是可以通过参考信号资源实际占用的符号数，以及slot自身的符号数限制(示例的，符号数限制可以理解为对参考信号资源的配置数量产生影响的因素，例如可以是上述涉及的预留gap位)做出相应调整的。Of course, it is only a feasible embodiment that the reference signal resources occupy one symbol bit, and the number of symbols actually occupied by the reference signal resources is not limited thereto. Correspondingly, for a slot, the configuration quantity of reference signal resources that it can support is the number of symbols that can be actually occupied by reference signal resources, and the limitation of the number of symbols of the slot itself (for example, the limitation of the number of symbols can be understood as Factors affecting the configuration quantity of reference signal resources, for example, may be adjusted accordingly by the above-mentioned reserved gap bits).

此外，对于资源位置信息包括单一sl-CSI-RS-FirstSymbol、多个sl-CSI-RS-FreqAllocation以及mini-slot数量和/或参考信号资源数量的情况，第一个mini-slot的时域起始位置可以通过sl-CSI-RS-FirstSymbol确定，而后续的mini-slot的时域起始位置则是基于第一个mini-slot的时域起始位置陆续确定的。例如，第二个mini-slot的时域起始位置，是基于第一个mini-slot的时域结束位置确定的。第三个mini-slot的时域起始位置，是基于第二个mini-slot的时域结束位置确定的。其中，以通过第一个mini-slot的时域结束位置确定第二个mini-slot的时域起始位置为例，第一个mini-slot的时域结束位置与第二个mini-slot的时域起始位置之间通过AGC占用的符号进行间隔，在第一个mini-slot的时域结束位置的基础上，补入AGC所占用的符号数，就可以得到第二个mini-slot的时域起始位置。In addition, when the resource location information includes a single sl-CSI-RS-FirstSymbol, multiple sl-CSI-RS-FreqAllocation and the number of mini-slots and/or the number of reference signal resources, the time domain of the first mini-slot starts from The initial position can be determined by sl-CSI-RS-FirstSymbol, and the initial position of the time domain of subsequent mini-slots is successively determined based on the initial position of the first mini-slot in the time domain. For example, the start position of the time domain of the second mini-slot is determined based on the end position of the time domain of the first mini-slot. The start position of the time domain of the third mini-slot is determined based on the end position of the time domain of the second mini-slot. Among them, taking the time domain end position of the first mini-slot to determine the time domain start position of the second mini-slot as an example, the time domain end position of the first mini-slot is the same as the second mini-slot The start position of the time domain is separated by the symbols occupied by AGC. On the basis of the end position of the time domain of the first mini-slot, the number of symbols occupied by AGC is added to obtain the second mini-slot. Time domain start position.

一实施方式中，资源位置信息包括单一sl-CSI-RS-FirstSymbol以及单一sl-CSI-RS-FreqAllocation，并包括slot数量和/或参考信号资源数量。In one embodiment, the resource location information includes a single sl-CSI-RS-FirstSymbol and a single sl-CSI-RS-FreqAllocation, and includes the number of slots and/or the number of reference signal resources.

其中，单一sl-CSI-RS-FirstSymbol用于确定多个参考信号资源对应的时域起始符号位置，单一sl-CSI-RS-FreqAllocation用于确定多个参考信号资源对应的RE位置以及端口数。Among them, a single sl-CSI-RS-FirstSymbol is used to determine the time-domain start symbol positions corresponding to multiple reference signal resources, and a single sl-CSI-RS-FreqAllocation is used to determine the RE positions and port numbers corresponding to multiple reference signal resources .

其中，多个参考信号资源中不同参考信号资源对应相同时域起始符号位置，且同一slot内的参考信号资源对应相同RE位置和端口数。换言之，对于资源位置信息包括用于确定多个参考信号资源对应时域起始符号位置的单一sl-CSI-RS-FirstSymbol，以及包括用于确定多个参考信号资源对应RE位置以及端口数的单一sl-CSI-RS-FreqAllocation，并包括slot数量和/或参考信号数量的情况。多个slot保持连续或不连续，CSI-RS资源的数量与slot数量保持一致。此时，不同CSI-RS资源对应不同slot，但不同CSI-RS资源对应了相同的时域起始符号位置、相同的RE位置、以及相同的端口数。Among the multiple reference signal resources, different reference signal resources correspond to the same time-domain start symbol position, and the reference signal resources in the same slot correspond to the same RE position and port number. In other words, the resource location information includes a single sl-CSI-RS-FirstSymbol used to determine the position of the start symbol in the time domain corresponding to multiple reference signal resources, and a single sl-CSI-RS-FreqAllocation, and includes the number of slots and/or the number of reference signals. Multiple slots are continuous or discontinuous, and the number of CSI-RS resources is consistent with the number of slots. At this time, different CSI-RS resources correspond to different slots, but different CSI-RS resources correspond to the same time-domain start symbol position, the same RE position, and the same number of ports.

本公开实施例提供的方法，当资源位置信息包括单一sl-CSI-RS-FirstSymbol、单一sl-CSI-RS-FreqAllocation以及slot数量和/或参考信号资源数量时，资源位置信息适用于基于slot的配置。In the method provided by the embodiments of the present disclosure, when the resource location information includes a single sl-CSI-RS-FirstSymbol, a single sl-CSI-RS-FreqAllocation, and the number of slots and/or the number of reference signal resources, the resource location information is suitable for slot-based configuration.

一实施方式中，资源位置信息包括单一sl-CSI-RS-FirstSymbol以及单一sl-CSI-RS-FreqAllocation，并包括mini-slot数量和/或参考信号资源数量。In one embodiment, the resource location information includes a single sl-CSI-RS-FirstSymbol and a single sl-CSI-RS-FreqAllocation, and includes the number of mini-slots and/or the number of reference signal resources.

其中，单一sl-CSI-RS-FirstSymbol用于确定多个参考信号资源对应的时域起始符号位置，单一sl-CSI-RS-FreqAllocation用于确定多个参考信号资源对应的RE位置以及端口数。Among them, a single sl-CSI-RS-FirstSymbol is used to determine the time-domain start symbol positions corresponding to multiple reference signal resources, and a single sl-CSI-RS-FreqAllocation is used to determine the RE positions and port numbers corresponding to multiple reference signal resources .

其中，多个参考信号资源中不同参考信号资源对应的时域起始符号位置为首个mini-slot所对应符号位置，多个mini-slot中相邻mini-slot之间具有设定数量符号间隔，且不同参考信号资源对应相同RE位置和端口数。Wherein, the time-domain starting symbol position corresponding to different reference signal resources in the multiple reference signal resources is the symbol position corresponding to the first mini-slot, and there is a set number of symbol intervals between adjacent mini-slots in the multiple mini-slots, And different reference signal resources correspond to the same RE position and number of ports.

Take sidelink CSI-RS as an example, hereinafter referred to as CSI-RS. Each CSI-RS resource needs to occupy M sign bits, and automatic gain control (automatic gain control, AGC) adjustment needs to be configured before the CSI-RS resource, and it needs to be additionally occupied before the sign bit occupied by the CSI-RS resource for AGC A sign bit of . In other words, for the configuration of one CSI-RS resource, M+1 sign bits need to be occupied. In addition, the slot itself needs to reserve a symbol as a gap. Therefore, when the configuration of a CSI-RS resource needs to occupy M+1 symbol bits and M=1, and the number of symbol bits supported by the slot is N (for example, When N is a positive integer), the number of CSI-RS resources that can be configured in one slot is N/2-1. For example, when the slot supports the configuration of 12 sign bits, a slot can contain up to 5 CSI-RS resources. When the slot supports the configuration of 14 sign bits, one slot can contain a maximum of 6 CSI-RS resources. When the sign bit of a slot is fully occupied, when configuring the subsequent CSI-RS resource configuration, continue to occupy the next slot in the continuous slots.

当然，参考信号资源占用一个符号位仅是一可行实施例，参考信号资源实际占用的符号数并不限于此。相应的，对于一个slot而言，其可支持的参考信号资源的配置数量，是可以通过参考信号资源实际占用的符号数，以及slot自身的符号数限制(示例的，符号数限制可以理解为对参考信号资源的配置数量产生影响的因素，例如可以是上述涉及的预留gap位)做出相应调整的。Of course, it is only a feasible embodiment that the reference signal resources occupy one symbol bit, and the number of symbols actually occupied by the reference signal resources is not limited thereto. Correspondingly, for a slot, the configuration quantity of reference signal resources that it can support is the number of symbols that can be actually occupied by reference signal resources, and the limitation of the number of symbols of the slot itself (for example, the limitation of the number of symbols can be understood as Factors affecting the configuration quantity of reference signal resources, for example, may be adjusted accordingly by the above-mentioned reserved gap bits).

此外，对于资源位置信息包括单一sl-CSI-RS-FirstSymbol、单一sl-CSI-RS-FreqAllocation以及mini-slot数量和/或参考信号资源数量的情况，第一个mini-slot的时域起始位置可以通过sl-CSI-RS-FirstSymbol确定，而后续的mini-slot的时域起始位置则是基于第一个mini-slot的时域起始位置陆续确定的。例如，第二个mini-slot的时域起始位置，是基于第一个mini-slot的时域结束位置确定的。第三个mini-slot的时域起始位置，是基于第二个mini-slot的时域结束位置确定的。其中，以通过第一个mini-slot的时域结束位置确定第二个mini-slot的时域起始位置为例，第一个mini-slot的时域结束位置与第二个mini-slot的时域起始位置之间通过AGC占用的符号进行间隔，在第一个mini-slot的时域结束位置的基础上，补入AGC所占用的符号数，就可以得到第二个mini-slot的时域起始位置。In addition, for resource location information including a single sl-CSI-RS-FirstSymbol, a single sl-CSI-RS-FreqAllocation and the number of mini-slots and/or the number of reference signal resources, the time domain start of the first mini-slot The position can be determined by sl-CSI-RS-FirstSymbol, and the time-domain starting positions of subsequent mini-slots are successively determined based on the time-domain starting position of the first mini-slot. For example, the start position of the time domain of the second mini-slot is determined based on the end position of the time domain of the first mini-slot. The start position of the time domain of the third mini-slot is determined based on the end position of the time domain of the second mini-slot. Among them, taking the time domain end position of the first mini-slot to determine the time domain start position of the second mini-slot as an example, the time domain end position of the first mini-slot is the same as the second mini-slot The start position of the time domain is separated by the symbols occupied by AGC. On the basis of the end position of the time domain of the first mini-slot, the number of symbols occupied by AGC is added to obtain the second mini-slot. Time domain start position.

在步骤S32中，基于第二配置信息确定参考信号资源配置信息。In step S32, reference signal resource configuration information is determined based on the second configuration information.

其中，方式一及方式二可以理解为通过配置信息的传输完成的参考信号资源配置信息的配置，方式三可以理解为通过协议规定的方式，对参考信号资源配置信息进行了预配置。Among them, mode 1 and mode 2 can be understood as the configuration of the reference signal resource configuration information completed through the transmission of configuration information, and mode 3 can be understood as the pre-configuration of the reference signal resource configuration information in a manner specified in the protocol.

The second configuration information may also be carried by, for example, a physical sidelink shared channel (Physical Sidelink Shared Channel, PSSCH) used between terminals, for example, carried by an SL MAC CE on the PSSCH. The second configuration information may also be carried by, for example, a physical sidelink control channel (Physical Sidelink Control Channel, PSCCH) used between terminals, for example, carried by sidelink control information SCI on the PSCCH.

基于相同的技术构思，本公开还提出了一种基于侧链路的通信方法，该方法由网络设备执行，通过与第一设备的交互，完成对第一设备的参考信号资源配置信息的配置。如若下述实施例中存在不清楚之处，可参见上述任意实施例。Based on the same technical idea, this disclosure also proposes a side link-based communication method, which is executed by a network device, and configures reference signal resource configuration information of the first device through interaction with the first device. In the event that something is unclear in the following examples, reference should be made to any of the above examples.

图5是根据一示例性实施例示出的一种基于侧链路的通信方法的流程图，如图5所示，基于侧链路的通信方法由网络设备执行，包括以下步骤。Fig. 5 is a flowchart showing a communication method based on a side link according to an exemplary embodiment. As shown in Fig. 5 , the communication method based on a side link is executed by a network device, and includes the following steps.

在步骤S41中，发送第一配置信息。In step S41, the first configuration information is sent.

本公开实施例中，第一配置信息是由网络设备发送的、用于使第一设备确定用于波束测量的参考信号资源配置信息，参考信号资源配置信息用于确定第一设备进行sidelink波束测量所对应的参考信号资源信息。网络设备将发送第一配置信息，以使终端通过第一配置信息获取参考信号资源配置信息，并通过参考信号资源配置信息确定进行sidelink波束测量所对应的参考信号资源信息。In the embodiment of the present disclosure, the first configuration information is sent by the network device and used to enable the first device to determine reference signal resource configuration information for beam measurement, and the reference signal resource configuration information is used to determine that the first device performs sidelink beam measurement Corresponding reference signal resource information. The network device will send the first configuration information, so that the terminal obtains reference signal resource configuration information through the first configuration information, and determines reference signal resource information corresponding to performing sidelink beam measurement through the reference signal resource configuration information.

本公开实施例提供的方法，参考信号资源配置信息包括参考信号资源位置信息和参考信号资源集合对应的重复状态中的至少一项。In the method provided by the embodiments of the present disclosure, the reference signal resource configuration information includes at least one item of reference signal resource position information and a repetition state corresponding to the reference signal resource set.

一示例中，参考信号资源信息包括参考信号资源位置信息。In an example, the reference signal resource information includes reference signal resource location information.

另一示例中，参考信号资源信息包括参考信号资源集合对应的重复状态。In another example, the reference signal resource information includes a repetition state corresponding to the reference signal resource set.

另一示例中，参考信号资源信息同时包括参考信号资源位置信息和参考信号资源集合对应的重复状态。In another example, the reference signal resource information includes reference signal resource location information and a repetition state corresponding to the reference signal resource set.

上述实施例中，参考信号资源集合包括多个参考信号资源，重复状态用于指示多个参考信号资源各自对应的波束是否相同。In the above embodiment, the reference signal resource set includes multiple reference signal resources, and the repetition state is used to indicate whether beams corresponding to the multiple reference signal resources are the same.

示例的，参考信号资源集合对应的重复状态包括开启(on)状态和关闭(off)状态。当参考信号资源集合对应的重复状态为开启(on)状态时，参考信号资源集合内的各个参考信号对应同一的波束。当参考信号资源集合对应的重复状态为开启(off)状态时，参考信号资源集合内的各个参考信号对应不同的波束。Exemplarily, the repeated states corresponding to the reference signal resource set include an on state and an off state. When the repetition state corresponding to the reference signal resource set is an on state, each reference signal in the reference signal resource set corresponds to the same beam. When the repetition state corresponding to the reference signal resource set is an on (off) state, each reference signal in the reference signal resource set corresponds to a different beam.

本公开实施例提供的方法，参考信号资源位置信息可以理解为与参考信号的时频资源位置相关的信息。示例的，资源位置信息例如可以包括至少一个时域起始符号位置、至少一个子载波位置、至少一个端口数、参考信号资源数、参考信号资源占用的slot数、参考信号资源占用的mini-slot数、参考信号资源占用的时间单元参考信号资源占用的起始资源块位置、参考信号资源占用的资源块数量、参考信号资源标识、以及参考信号资源集合标识之一或组合。其中，参考信号资源占用的时间单元可以是slot或mini-slot。In the method provided by the embodiments of the present disclosure, the reference signal resource location information may be understood as information related to the time-frequency resource location of the reference signal. For example, the resource location information may include at least one time domain start symbol location, at least one subcarrier location, at least one port number, number of reference signal resources, number of slots occupied by reference signal resources, and mini-slot occupied by reference signal resources One or a combination of number, time unit occupied by reference signal resources, starting resource block position occupied by reference signal resources, number of resource blocks occupied by reference signal resources, reference signal resource identifier, and reference signal resource set identifier. Wherein, the time unit occupied by the reference signal resource may be slot or mini-slot.

其中，mini-slot是相对于以slot为粒度而言。以slot为粒度进行调度时，占用的符号数最小可以为3。以mini-slot为粒度进行调度时，占用的符号数最小可以为1或2。而且一个slot可以包含多个mini-slot的调度单元，一个mini-slot还可以占用两个相邻slot的符号。Among them, mini-slot is relative to the granularity of slot. When the slot is used as the granularity for scheduling, the minimum number of occupied symbols can be 3. When scheduling at the granularity of mini-slot, the minimum number of occupied symbols can be 1 or 2. Moreover, a slot can contain multiple mini-slot scheduling units, and a mini-slot can also occupy symbols of two adjacent slots.

本公开实施例提供的方法，资源位置信息可以包括参考信号时域起始符号位置信息(例如sl-CSI-RS-FirstSymbol)，以及包括参考信号频域资源位置信息(例如sl-CSI-RS-FreqAllocation)。其中，sl-CSI-RS-FirstSymbol用于确定参考信号资源对应的时域起始符号位置，sl-CSI-RS-FreqAllocation用于确定参考信号资源对应的RE位置以及端口数。In the method provided by the embodiments of the present disclosure, the resource position information may include reference signal time domain start symbol position information (such as sl-CSI-RS-FirstSymbol), and reference signal frequency domain resource position information (such as sl-CSI-RS-FirstSymbol) FreqAllocation). Among them, sl-CSI-RS-FirstSymbol is used to determine the time-domain start symbol position corresponding to the reference signal resource, and sl-CSI-RS-FreqAllocation is used to determine the RE position and port number corresponding to the reference signal resource.

本公开实施例中，参考信号资源配置信息包括参考信号资源位置信息。一实施方式中，可以通过参考信号资源位置信息配置sl-CSI-RS-FirstSymbol和sl-CSI-RS-FreqAllocation。并且，示例的，资源位置信息可以包括一个或多个sl-CSI-RS-FirstSymbol，以及包括一个或多个sl-CSI-RS-FreqAllocation。In the embodiment of the present disclosure, the reference signal resource configuration information includes reference signal resource location information. In one embodiment, the sl-CSI-RS-FirstSymbol and sl-CSI-RS-FreqAllocation can be configured through reference signal resource location information. And, for example, the resource location information may include one or more sl-CSI-RS-FirstSymbols, and one or more sl-CSI-RS-FreqAllocation.

一实施方式中，资源位置信息包括多个sl-CSI-RS-FirstSymbol以及多个sl-CSI-RS-FreqAllocation。其中，多个sl-CSI-RS-FirstSymbol用于确定多个参考信号资源各自分别对应的时域起始符号位置，多个sl-CSI-RS-FreqAllocation用于确定多个参考信号资源各自分别对应的RE位置以及端口数。In one embodiment, the resource location information includes multiple sl-CSI-RS-FirstSymbols and multiple sl-CSI-RS-FreqAllocations. Among them, multiple sl-CSI-RS-FirstSymbols are used to determine the time-domain start symbol positions corresponding to multiple reference signal resources, and multiple sl-CSI-RS-FreqAllocation are used to determine multiple reference signal resources. The location of the RE and the number of ports.

其中，多个参考信号资源与多个sl-CSI-RS-FirstSymbol之间是一一对应的关系，多个参考信号资源与多个sl-CSI-RS-FreqAllocation之间也是一一对应的关系。该情况下，相当于为多个参考信号资源中的每个参考信号资源，分别独立配置了sl-CSI-RS-FirstSymbol和sl-CSI-RS-FreqAllocation。也即，为多个参考信号资源中的每个参考信号资源，分别独立配置了时域起始符号位置、RE位置以及端口数。There is a one-to-one correspondence between multiple reference signal resources and multiple sl-CSI-RS-FirstSymbols, and there is also a one-to-one correspondence between multiple reference signal resources and multiple sl-CSI-RS-FreqAllocations. In this case, it is equivalent to configuring sl-CSI-RS-FirstSymbol and sl-CSI-RS-FreqAllocation independently for each of the plurality of reference signal resources. That is, for each reference signal resource among the plurality of reference signal resources, the time-domain start symbol position, RE position, and port number are independently configured.

示例的，通过sl-CSI-RS-FirstSymbol确定时域起始符号位置的方式，可以适用于一个slot包含一个CSI-RS资源的情况，也可以适用于一个slot包含多个CSI-RS资源的情况。在此基础上，为使终端可以进一步明确slot包含CSI-RS资源的具体情况，网络设备可进一步使用资源位置信息，通过显式指示方式或默认规则，对slot包含CSI-RS资源的情况做出指示。For example, the method of determining the start symbol position in the time domain through sl-CSI-RS-FirstSymbol can be applied to the case where a slot contains one CSI-RS resource, and can also be applied to the case where a slot contains multiple CSI-RS resources . On this basis, in order for the terminal to further clarify the specific situation that the slot contains CSI-RS resources, the network device can further use the resource location information to make a decision on the situation that the slot contains CSI-RS resources through explicit instructions or default rules. instruct.

一示例中，可以通过资源位置信息指示每个CSI-RS资源对应的slot位置，相当于资源以显式指示方式对slot包含CSI-RS资源的情况进行了指示。在此基础上，资源位置信息可以用于指示多个参考信号资源各自分别对应的slot位置，第一设备可基于资源位置信息确定每个CSI-RS资源对应的slot位置。In an example, the slot position corresponding to each CSI-RS resource may be indicated through the resource position information, which is equivalent to the fact that the resource indicates that the slot contains the CSI-RS resource in an explicit manner. On this basis, the resource location information may be used to indicate slot locations corresponding to the multiple reference signal resources, and the first device may determine the slot location corresponding to each CSI-RS resource based on the resource location information.

另一示例中，可以通过资源位置信息对CSI-RS资源所占用的时间单元做出指示。例如，资源位置信息可以用于指示多个参考信号资源占用的slot数。在此基础上，资源位置信息可以用于指示多个参考信号资源占用的slot数，第一设备可基于资源位置信息确定多个参考信号资源占用的slot数。此外，资源位置信息还可以用于指示多个参考信号资源占用的mini-slot数。在此基础上，资源位置信息可以用于指示多个参考信号资源占用的mini-slot数，第一设备可基于资源位置信息确定多个参考信号资源占用的mini-slot数。In another example, the time unit occupied by the CSI-RS resource may be indicated through resource location information. For example, the resource location information may be used to indicate the number of slots occupied by multiple reference signal resources. On this basis, the resource location information may be used to indicate the number of slots occupied by multiple reference signal resources, and the first device may determine the number of slots occupied by multiple reference signal resources based on the resource location information. In addition, the resource location information may also be used to indicate the number of mini-slots occupied by multiple reference signal resources. On this basis, the resource location information may be used to indicate the number of mini-slots occupied by multiple reference signal resources, and the first device may determine the number of mini-slots occupied by multiple reference signal resources based on the resource location information.

其中，不同参考信号资源可以对应相同或不同的slot位置。Wherein, different reference signal resources may correspond to the same or different slot positions.

例如，当资源位置信息用于指示多个参考信号资源各自分别对应的slot位置时，对于对应相同slot位置的参考信号资源而言，不同参考信号资源对应的时域起始符号位置需要不同。而对于对应不同slot位置的参考信号资源而言，不同参考信号资源对应的时域起始符号位置可以相同或不同。又例如，当资源位置信息用于指示多个参考信号资源占用的slot数时，不同CSI-RS资源对应的slot位置不同。又例如，当资源位置信息用于指示多个参考信号资源占用的mini-slot数时，资源位置信息指示基于mini-slot的传输，不同CSI-RS资源对应的slot位置可以相同或不同。For example, when the resource position information is used to indicate the respective slot positions corresponding to multiple reference signal resources, for reference signal resources corresponding to the same slot position, the time-domain start symbol positions corresponding to different reference signal resources need to be different. For reference signal resources corresponding to different slot positions, the time-domain start symbol positions corresponding to different reference signal resources may be the same or different. For another example, when the resource position information is used to indicate the number of slots occupied by multiple reference signal resources, slot positions corresponding to different CSI-RS resources are different. For another example, when the resource location information is used to indicate the number of mini-slots occupied by multiple reference signal resources, the resource location information indicates mini-slot-based transmission, and slot locations corresponding to different CSI-RS resources may be the same or different.

本公开实施例提供的方法，参考信号可以是sidelink CSI-RS。以sidelink CSI-RS为例，后续我们简称为CSI-RS。每个CSI-RS资源需要占用M个符号位，且CSI-RS资源前需要AGC调整，需要在CSI-RS资源所占用的符号位前额外占用用于AGC的一个符号位。换言之，对于一个CSI-RS资源的配置，需要占用M+1个符号位。此外，slot本身需要预留一个符号为gap，因此，当一个CSI-RS资源的配置需要M个符号位且M＝1时，且slot支持配置的符号位数为N(示例的，N为正整数)时，一个slot可配置的CSI-RS资源的数量为N/2-1。例如，当slot支持12个符号位的配置时，一个slot可以包含最多5个CSI-RS资源。当slot支持14个符号位的配置时，一个slot可以包含最多6个CSI-RS。当一个slot的符号位被占满时，配置后续的CSI-RS资源配置时，则继续占用连续slot中的下一个slot。In the method provided by the embodiments of the present disclosure, the reference signal may be a sidelink CSI-RS. Taking sidelink CSI-RS as an example, we will refer to it as CSI-RS for short. Each CSI-RS resource needs to occupy M sign bits, and AGC adjustment is required before the CSI-RS resource, and an additional sign bit for AGC needs to be occupied before the sign bit occupied by the CSI-RS resource. In other words, for the configuration of one CSI-RS resource, M+1 sign bits need to be occupied. In addition, the slot itself needs to reserve a symbol as a gap. Therefore, when the configuration of a CSI-RS resource requires M sign bits and M=1, and the number of sign bits supported by the slot is N (in the example, N is positive integer), the number of configurable CSI-RS resources for one slot is N/2-1. For example, when the slot supports the configuration of 12 sign bits, a slot can contain up to 5 CSI-RS resources. When the slot supports the configuration of 14 sign bits, a slot can contain a maximum of 6 CSI-RSs. When the sign bit of a slot is fully occupied, when configuring the subsequent CSI-RS resource configuration, continue to occupy the next slot in the continuous slots.

一实施方式中，资源位置信息包括多个sl-CSI-RS-FirstSymbol以及单一sl-CSI-RS-FreqAllocation。其中，多个sl-CSI-RS-FirstSymbol用于确定多个参考信号资源各自分别对应的时域起始符号位置，单一sl-CSI-RS-FreqAllocation用于确定多个参考信号资源对应的RE位置以及端口数。In one embodiment, the resource location information includes multiple sl-CSI-RS-FirstSymbols and a single sl-CSI-RS-FreqAllocation. Among them, multiple sl-CSI-RS-FirstSymbols are used to determine the time-domain start symbol positions corresponding to multiple reference signal resources, and a single sl-CSI-RS-FreqAllocation is used to determine the RE positions corresponding to multiple reference signal resources and the number of ports.

其中，多个参考信号资源与多个sl-CSI-RS-FirstSymbol之间是一一对应的关系。该情况下，相当于为多个参考信号资源中的每个参考信号资源，分别独立配置了sl-CSI-RS-FirstSymbol，且不同参考信号资源相比，时域起始符号位置可以相同或不同。此外，资源位置信息还包括用于确定多个参考信号资源对应RE位置以及端口数的单一sl-CSI-RS-FreqAllocation，该单一sl-CSI-RS-FreqAllocation可以理解为多个参考信号资源共用的sl-CSI-RS-FreqAllocation。换言之，多个参考信号资源各自对应了同样的sl-CSI-RS-FreqAllocation。该情况下，每个参考信号资源对应的RE位置和端口数是一样的。There is a one-to-one correspondence between multiple reference signal resources and multiple sl-CSI-RS-FirstSymbols. In this case, it is equivalent to configuring sl-CSI-RS-FirstSymbol independently for each of the multiple reference signal resources, and compared with different reference signal resources, the position of the start symbol in the time domain can be the same or different . In addition, the resource location information also includes a single sl-CSI-RS-FreqAllocation for determining the RE location and the number of ports corresponding to multiple reference signal resources. The single sl-CSI-RS-FreqAllocation can be understood as a shared sl-CSI-RS-FreqAllocation. In other words, the multiple reference signal resources each correspond to the same sl-CSI-RS-FreqAllocation. In this case, the RE positions and port numbers corresponding to each reference signal resource are the same.

示例的，通过sl-CSI-RS-FirstSymbol来确定时域起始符号位置的方式，可以适用于一个slot包含一个CSI-RS资源的情况，也可以适用于一个slot包含多个CSI-RS资源的情况。在此基础上，为使终端可以进一步明确slot包含CSI-RS资源的具体情况，可使用资源位置信息，通过显式指示方式或默认规则，对slot包含CSI-RS资源的情况做出指示。其中，由于通过资源位置信息确定CSI-RS资源所占用的时间单元的实现方式，本公开上述实施例中已经进行了说明，因此具体实现方式可直接参考上述实施例，本公开在此不做赘述。For example, the method of determining the start symbol position in the time domain through sl-CSI-RS-FirstSymbol can be applied to the case where a slot contains one CSI-RS resource, and can also be applied to the case where a slot contains multiple CSI-RS resources Condition. On this basis, in order to enable the terminal to further clarify the specific situation that the slot contains CSI-RS resources, the resource location information can be used to indicate the situation that the slot contains CSI-RS resources through an explicit indication method or a default rule. Wherein, since the implementation of determining the time unit occupied by the CSI-RS resources through the resource location information has been described in the above-mentioned embodiments of the present disclosure, the specific implementation methods can directly refer to the above-mentioned embodiments, and the present disclosure will not repeat them here. .

一实施方式中，资源位置信息包括单一sl-CSI-RS-FirstSymbol以及多个sl-CSI-RS-FreqAllocation。其中，单一sl-CSI-RS-FirstSymbol用于确定多个参考信号资源对应的时域起始符号位置的，多个sl-CSI-RS-FreqAllocation用于确定多个参考信号资源各自分别对应的RE位置以及端口数。In one embodiment, the resource location information includes a single sl-CSI-RS-FirstSymbol and multiple sl-CSI-RS-FreqAllocations. Among them, a single sl-CSI-RS-FirstSymbol is used to determine the time-domain start symbol positions corresponding to multiple reference signal resources, and multiple sl-CSI-RS-FreqAllocation are used to determine REs corresponding to multiple reference signal resources respectively location and number of ports.

例如，资源位置信息包括单一sl-CSI-RS-FirstSymbol以及多个sl-CSI-RS-FreqAllocation，并包括slot数量和/或参考信号资源数量。其中，多个参考信号资源中不同参考信号资源对应相同时域起始符号位置。而多个参考信号资源与多个sl-CSI-RS-FreqAllocation之间是一一对应的关系，相当于为多个参考信号资源中的每个参考信号资源，分别独立配置了sl-CSI-RS-FreqAllocation。也即，为多个参考信号资源中的每个参考信号资源，分别独立配置了RE位置以及端口数。此时，不同CSI-RS资源对应不同slot，但对应相同时域起始符号位置。并且，不同CSI-RS资源对应的RE位置和端口数可以相同或不同。For example, the resource location information includes a single sl-CSI-RS-FirstSymbol and multiple sl-CSI-RS-FreqAllocations, and includes the number of slots and/or the number of reference signal resources. Wherein, different reference signal resources among the multiple reference signal resources correspond to the same time-domain start symbol position. There is a one-to-one correspondence between multiple reference signal resources and multiple sl-CSI-RS-FreqAllocations, which is equivalent to independently configuring sl-CSI-RS for each of the multiple reference signal resources. -FreqAllocation. That is, for each reference signal resource among the plurality of reference signal resources, the position of RE and the number of ports are independently configured. At this time, different CSI-RS resources correspond to different slots, but correspond to the same start symbol position in the time domain. In addition, RE positions and port numbers corresponding to different CSI-RS resources may be the same or different.

又例如，资源位置信息包括单一sl-CSI-RS-FirstSymbol以及多个sl-CSI-RS-FreqAllocation，并包括mini-slot数量和/或参考信号资源数量。其中，多个参考信号资源与多个sl-CSI-RS-FreqAllocation之间是一一对应的关系，相当于为多个参考信号资源中的每个参考信号资源，分别独立配置了sl-CSI-RS-FreqAllocation。也即，为多个参考信号资源中的每个参考信号资源，分别独立配置了RE位置以及端口数，不同CSI-RS资源对应的RE位置和端口数可以相同或不同。并且，多个参考信号资源中不同参考信号资源对应的时域起始符号位置为首个mini-slot所对应符号位置，多个mini-slot中相邻mini-slot之间具有设定数量符号间隔，且不同参考信号资源对应相同或不同的RE位置和端口数。For another example, the resource location information includes a single sl-CSI-RS-FirstSymbol and multiple sl-CSI-RS-FreqAllocations, and includes the number of mini-slots and/or the number of reference signal resources. Among them, there is a one-to-one correspondence relationship between multiple reference signal resources and multiple sl-CSI-RS-FreqAllocations, which is equivalent to independently configuring sl-CSI-RS-FreqAllocation for each of the multiple reference signal resources. RS-FreqAllocation. That is, for each reference signal resource among the plurality of reference signal resources, RE positions and port numbers are configured independently, and the RE positions and port numbers corresponding to different CSI-RS resources may be the same or different. In addition, the time-domain starting symbol positions corresponding to different reference signal resources in the multiple reference signal resources are the symbol positions corresponding to the first mini-slot, and there is a set number of symbol intervals between adjacent mini-slots in the multiple mini-slots, And different reference signal resources correspond to the same or different RE positions and port numbers.

示例的，参考信号可以是sidelink CSI-RS。以sidelink CSI-RS为例，后面简称CSI-RS。每个CSI-RS资源需要占用M个符号位，且CSI-RS资源前需要配置自动增益控制(automatic gain control，AGC)调整，需要在CSI-RS资源所占用的符号位前额外占用用于AGC的一个符号位。换言之，对于一个CSI-RS资源的配置，需要占用M+1个符号位。此外，slot本身需要预留一个符号为gap，因此，当一个CSI-RS资源的配置需要占用M+1个符号位且M＝1时，且slot支持配置的符号位数为N(示例的，N为正整数)时，一个slot可配置的CSI-RS资源的数量为N/2-1。例如，当slot支持12个符号位的配置时，一个slot可以包含最多5个CSI-RS资源。当slot支持14个符号位的配置时，一个slot可以包含最多6个CSI-RS资源。当一个slot的符号位被占满时，配置后续的CSI-RS资源配置时，则继续占用连续slot中的下一个slot。Exemplarily, the reference signal may be a sidelink CSI-RS. Take the sidelink CSI-RS as an example, hereinafter referred to as CSI-RS. Each CSI-RS resource needs to occupy M sign bits, and automatic gain control (automatic gain control, AGC) adjustment needs to be configured before the CSI-RS resource, and it needs to be additionally occupied before the sign bit occupied by the CSI-RS resource for AGC A sign bit of . In other words, for the configuration of one CSI-RS resource, M+1 sign bits need to be occupied. In addition, the slot itself needs to reserve a symbol as a gap. Therefore, when the configuration of a CSI-RS resource needs to occupy M+1 symbol bits and M=1, and the number of symbol bits supported by the slot is N (for example, When N is a positive integer), the number of CSI-RS resources that can be configured in one slot is N/2-1. For example, when the slot supports the configuration of 12 sign bits, a slot can contain up to 5 CSI-RS resources. When the slot supports the configuration of 14 sign bits, one slot can contain a maximum of 6 CSI-RS resources. When the sign bit of a slot is fully occupied, when configuring the subsequent CSI-RS resource configuration, continue to occupy the next slot in the continuous slots.

当然，参考信号资源占用一个符号位仅是一可行实施例，参考信号资源实际占用的符号数并不限于此。相应的，对于一个slot而言，其可支持的参考信号资源的配置数量，是可以通过参考信号资源实际占用的符号数，以及slot自身的符号数限制(示例的，符号数限制可以理解为对参考信号资源的配置数量产生影响的因素，例如可以是上述涉及的预留gap位)做出相应调整的。Of course, it is only a feasible embodiment that the reference signal resources occupy one symbol bit, and the number of symbols actually occupied by the reference signal resources is not limited thereto. Correspondingly, for a slot, the configuration quantity of reference signal resources that it can support is the number of symbols that can be actually occupied by reference signal resources, and the limitation of the number of symbols of the slot itself (for example, the limitation of the number of symbols can be understood as Factors affecting the configuration quantity of reference signal resources, for example, may be adjusted accordingly by the above-mentioned reserved gap bits).

此外，对于资源位置信息包括单一sl-CSI-RS-FirstSymbol、多个sl-CSI-RS-FreqAllocation以及mini-slot数量和/或参考信号资源数量的情况，第一个mini-slot的时域起始位置可以通过sl-CSI-RS-FirstSymbol确定，而后续的mini-slot的时域起始位置则是基于第一个mini-slot的时域起始位置陆续确定的。例如，第二个mini-slot的时域起始位置，是基于第一个mini-slot的时域结束位置确定的。第三个mini-slot的时域起始位置，是基于第二个mini-slot的时域结束位置确定的。其中，以通过第一个mini-slot的时域结束位置确定第二个mini-slot的时域起始位置为例，第一个mini-slot的时域结束位置与第二个mini-slot的时域起始位置之间通过AGC占用的符号进行间隔，在第一个mini-slot的时域结束位置的基础上，补入AGC所占用的符号数，就可以得到第二个mini-slot的时域起始位置。In addition, when the resource location information includes a single sl-CSI-RS-FirstSymbol, multiple sl-CSI-RS-FreqAllocation and the number of mini-slots and/or the number of reference signal resources, the time domain of the first mini-slot starts from The initial position can be determined by sl-CSI-RS-FirstSymbol, and the initial position of the time domain of subsequent mini-slots is successively determined based on the initial position of the first mini-slot in the time domain. For example, the start position of the time domain of the second mini-slot is determined based on the end position of the time domain of the first mini-slot. The start position of the time domain of the third mini-slot is determined based on the end position of the time domain of the second mini-slot. Among them, taking the time domain end position of the first mini-slot to determine the time domain start position of the second mini-slot as an example, the time domain end position of the first mini-slot is the same as the second mini-slot The start position of the time domain is separated by the symbols occupied by AGC. On the basis of the end position of the time domain of the first mini-slot, the number of symbols occupied by AGC is added to obtain the second mini-slot. Time domain start position.

一实施方式中，资源位置信息包括单一sl-CSI-RS-FirstSymbol以及单一sl-CSI-RS-FreqAllocation，并包括slot数量和/或参考信号资源数量。In one embodiment, the resource location information includes a single sl-CSI-RS-FirstSymbol and a single sl-CSI-RS-FreqAllocation, and includes the number of slots and/or the number of reference signal resources.

其中，单一sl-CSI-RS-FirstSymbol用于确定多个参考信号资源对应的时域起始符号位置，单一sl-CSI-RS-FreqAllocation用于确定多个参考信号资源对应的RE位置以及端口数。Among them, a single sl-CSI-RS-FirstSymbol is used to determine the time-domain start symbol positions corresponding to multiple reference signal resources, and a single sl-CSI-RS-FreqAllocation is used to determine the RE positions and port numbers corresponding to multiple reference signal resources .

其中，多个参考信号资源中不同参考信号资源对应相同时域起始符号位置，且同一slot内的参考信号资源对应相同RE位置和端口数。换言之，对于资源位置信息包括用于确定多个参考信号资源对应时域起始符号位置的单一sl-CSI-RS-FirstSymbol，以及包括用于确定多个参考信号资源对应RE位置以及端口数的单一sl-CSI-RS-FreqAllocation，并包括slot数量和/或参考信号数量的情况。多个slot保持连续或不连续，CSI-RS资源的数量与slot数量保持一致。此时，不同CSI-RS资源对应不同slot，但不同CSI-RS资源对应了相同的时域起始符号位置、相同的RE位置、以及相同的端口数。Among the multiple reference signal resources, different reference signal resources correspond to the same time-domain start symbol position, and the reference signal resources in the same slot correspond to the same RE position and port number. In other words, the resource location information includes a single sl-CSI-RS-FirstSymbol used to determine the position of the start symbol in the time domain corresponding to multiple reference signal resources, and a single sl-CSI-RS-FreqAllocation, and includes the number of slots and/or the number of reference signals. Multiple slots are continuous or discontinuous, and the number of CSI-RS resources is consistent with the number of slots. At this time, different CSI-RS resources correspond to different slots, but different CSI-RS resources correspond to the same time-domain start symbol position, the same RE position, and the same number of ports.

本公开实施例提供的方法，当资源位置信息包括单一sl-CSI-RS-FirstSymbol、单一sl-CSI-RS-FreqAllocation以及slot数量和/或参考信号资源数量时，资源位置信息适用于基于slot的配置。In the method provided by the embodiments of the present disclosure, when the resource location information includes a single sl-CSI-RS-FirstSymbol, a single sl-CSI-RS-FreqAllocation, and the number of slots and/or the number of reference signal resources, the resource location information is suitable for slot-based configuration.

一实施方式中，资源位置信息包括单一sl-CSI-RS-FirstSymbol以及单一sl-CSI-RS-FreqAllocation，并包括mini-slot数量和/或参考信号资源数量。In one embodiment, the resource location information includes a single sl-CSI-RS-FirstSymbol and a single sl-CSI-RS-FreqAllocation, and includes the number of mini-slots and/or the number of reference signal resources.

其中，单一sl-CSI-RS-FirstSymbol用于确定多个参考信号资源对应的时域起始符号位置，单一sl-CSI-RS-FreqAllocation用于确定多个参考信号资源对应的RE位置以及端口数。Among them, a single sl-CSI-RS-FirstSymbol is used to determine the time-domain start symbol positions corresponding to multiple reference signal resources, and a single sl-CSI-RS-FreqAllocation is used to determine the RE positions and port numbers corresponding to multiple reference signal resources .

其中，多个参考信号资源中不同参考信号资源对应的时域起始符号位置为首个mini-slot所对应符号位置，多个mini-slot中相邻mini-slot之间具有设定数量符号间隔，且不同参考信号资源对应相同RE位置和端口数。Wherein, the time-domain starting symbol position corresponding to different reference signal resources in the multiple reference signal resources is the symbol position corresponding to the first mini-slot, and there is a set number of symbol intervals between adjacent mini-slots in the multiple mini-slots, And different reference signal resources correspond to the same RE position and number of ports.

示例的，参考信号可以是sidelink CSI-RS。以sidelink CSI-RS为例，后面简称CSI-RS。每个CSI-RS资源需要占用M个符号位，且CSI-RS资源前需要配置AGC调整，需要在CSI-RS资源所占用的符号位前额外占用用于AGC的一个符号位。换言之，对于一个CSI-RS资源的配置，需要占用M+1个符号位。此外，slot本身需要预留一个符号为gap，因此，当一个CSI-RS资源的配置需要占用M+1个符号位且M＝1时，且slot支持配置的符号位数为N(示例的，N为正整数)时，一个slot可配置的CSI-RS资源的数量为N/2-1。例如，当slot支持12个符号位的配置时，一个slot可以包含最多5个CSI-RS资源。当slot支持14个符号位的配置时，一个slot可以包含最多6个CSI-RS资源。当一个slot的符号位被占满时，配置后续的CSI-RS资源配置时，则继续占用连续slot中的下一个slot。Exemplarily, the reference signal may be a sidelink CSI-RS. Take the sidelink CSI-RS as an example, hereinafter referred to as CSI-RS. Each CSI-RS resource needs to occupy M sign bits, and AGC adjustment needs to be configured before the CSI-RS resource, and an additional sign bit for AGC needs to be occupied before the sign bit occupied by the CSI-RS resource. In other words, for the configuration of one CSI-RS resource, M+1 sign bits need to be occupied. In addition, the slot itself needs to reserve a symbol as a gap. Therefore, when the configuration of a CSI-RS resource needs to occupy M+1 symbol bits and M=1, and the number of symbol bits supported by the slot is N (for example, When N is a positive integer), the number of CSI-RS resources that can be configured in one slot is N/2-1. For example, when the slot supports the configuration of 12 sign bits, a slot can contain up to 5 CSI-RS resources. When the slot supports the configuration of 14 sign bits, one slot can contain a maximum of 6 CSI-RS resources. When the sign bit of a slot is fully occupied, when configuring the subsequent CSI-RS resource configuration, continue to occupy the next slot in the continuous slots.

当然，参考信号资源占用一个符号位仅是一可行实施例，参考信号资源实际占用的符号数并不限于此。相应的，对于一个slot而言，其可支持的参考信号资源的配置数量，是可以通过参考信号资源实际占用的符号数，以及slot自身的符号数限制(示例的，符号数限制可以理解为对参考信号资源的配置数量产生影响的因素，例如可以是上述涉及的预留gap位)做出相应调整的。Of course, it is only a feasible embodiment that the reference signal resources occupy one symbol bit, and the number of symbols actually occupied by the reference signal resources is not limited thereto. Correspondingly, for a slot, the configuration quantity of reference signal resources that it can support is the number of symbols that can be actually occupied by reference signal resources, and the limitation of the number of symbols of the slot itself (for example, the limitation of the number of symbols can be understood as Factors affecting the configuration quantity of reference signal resources, for example, may be adjusted accordingly by the above-mentioned reserved gap bits).

此外，对于资源位置信息包括单一sl-CSI-RS-FirstSymbol、单一sl-CSI-RS-FreqAllocation以及mini-slot数量和/或参考信号资源数量的情况，第一个mini-slot的时域起始位置可以通过sl-CSI-RS-FirstSymbol确定，而后续的mini-slot的时域起始位置则是基于第一个mini-slot的时域起始位置陆续确定的。例如，第二个mini-slot的时域起始位置，是基于第一个mini-slot的时域结束位置确定的。第三个mini-slot的时域起始位置，是基于第二个mini-slot的时域结束位置确定的。其中，以通过第一个mini-slot的时域结束位置确定第二个mini-slot的时域起始位置为例，第一个mini-slot的时域结束位置与第二个mini-slot的时域起始位置之间通过AGC占用的符号进行间隔，在第一个mini-slot的时域结束位置的基础上，补入AGC所占用的符号数，就可以得到第二个mini-slot的时域起始位置。In addition, for resource location information including a single sl-CSI-RS-FirstSymbol, a single sl-CSI-RS-FreqAllocation and the number of mini-slots and/or the number of reference signal resources, the time domain start of the first mini-slot The position can be determined by sl-CSI-RS-FirstSymbol, and the time-domain starting positions of subsequent mini-slots are successively determined based on the time-domain starting position of the first mini-slot. For example, the start position of the time domain of the second mini-slot is determined based on the end position of the time domain of the first mini-slot. The start position of the time domain of the third mini-slot is determined based on the end position of the time domain of the second mini-slot. Among them, taking the time domain end position of the first mini-slot to determine the time domain start position of the second mini-slot as an example, the time domain end position of the first mini-slot is the same as the second mini-slot The start position of the time domain is separated by the symbols occupied by AGC. On the basis of the end position of the time domain of the first mini-slot, the number of symbols occupied by AGC is added to obtain the second mini-slot. Time domain start position.

本公开实施例提供的方法，当资源位置信息包括单一sl-CSI-RS-FirstSymbol、单一sl-CSI-RS-FreqAllocation以及mini-slot数量和/或参考信号资源数量时，资源位置信息适用于基于mini-slot的配置。In the method provided by the embodiments of the present disclosure, when the resource location information includes a single sl-CSI-RS-FirstSymbol, a single sl-CSI-RS-FreqAllocation, and the number of mini-slots and/or the number of reference signal resources, the resource location information is applicable to Configuration of mini-slots.

本公开实施例提供的方法，基于上述实施例可知，同一slot内可以包括一个或多个参考信号资源。The method provided by the embodiments of the present disclosure can be known based on the above embodiments, one or more reference signal resources may be included in the same slot.

此外，本公开一可行实施方式中，参考信号资源配置信息还可以进一步包括起始RB位置和带宽配置中的至少一项。其中，对于起始资源块位置和带宽配置，可采用的配置方式包括显式配置方式以及默认配置方式。以默认配置方式为例，可以将起始资源块位置和/或带宽配置默认配置为与指定PSSCH的起始RB位置和带宽相一致。其中，指定PSSCH例如可以是最近一次已传输的PSSCH。或指定PSSCH可以是波束测量请求所在的SCI中指示的时域资源和频域资源对应的PSSCH，其中时域资源和频域资源可以是SCI中直接指示的也可以是SCI中的预留资源指示的。即波束测量请求对应的SCI与PSSCH资源指示对应的SCI相同，其中该SCI可以是第一阶段SCI和/或第二阶段SCI。In addition, in a feasible implementation manner of the present disclosure, the reference signal resource configuration information may further include at least one of a starting RB position and a bandwidth configuration. Wherein, for the starting resource block position and bandwidth configuration, available configuration methods include an explicit configuration method and a default configuration method. Taking the default configuration mode as an example, the starting resource block position and/or bandwidth configuration can be configured by default to be consistent with the starting RB position and bandwidth of the specified PSSCH. Wherein, the specified PSSCH may be, for example, the last transmitted PSSCH. Or the specified PSSCH can be the PSSCH corresponding to the time domain resources and frequency domain resources indicated in the SCI where the beam measurement request is located, where the time domain resources and frequency domain resources can be directly indicated in the SCI or reserved resource indications in the SCI of. That is, the SCI corresponding to the beam measurement request is the same as the SCI corresponding to the PSSCH resource indication, where the SCI may be the first-stage SCI and/or the second-stage SCI.

示例的，参考信号包括侧链路信道状态信息和侧链路同步信号块中的至少一项。Exemplarily, the reference signal includes at least one item of sidelink channel state information and sidelink synchronization signal block.

可以理解的是，本公开实施例中网络设备进行基于sidelink的通信的过程中涉及的技术实现，可以适用于本公开实施例第一设备进行基于sidelink的通信的过程，故对于网络设备进行基于sidelink的通信的过程一些技术实现描述不够详尽的地方可以参阅第一设备进行基于sidelink的通信的实施过程中的相关描述，在此不再赘述。It can be understood that the technical implementation involved in the sidelink-based communication process of the network device in the embodiment of the present disclosure can be applied to the sidelink-based communication process of the first device in the embodiment of the present disclosure, so the sidelink-based communication of the network device For some technical implementation descriptions of the communication process that are not detailed enough, please refer to the related description in the implementation process of the sidelink-based communication performed by the first device, which will not be repeated here.

基于相同的技术构思，本公开还提出了一种基于侧链路的通信方法，该方法由第二设备执行，通过与第一设备的交互，完成对第一设备的参考信号资源配置信息的配置。如若下述实施例中存在不清楚之处，可参见上述任意实施例。Based on the same technical concept, this disclosure also proposes a side link-based communication method, which is executed by the second device, and completes the configuration of the reference signal resource configuration information of the first device through interaction with the first device . In the event that something is unclear in the following examples, reference should be made to any of the above examples.

图6是根据一示例性实施例示出的一种基于侧链路的通信方法的流程图，如图6所示，基于侧链路的通信方法由第二设备执行，包括以下步骤。Fig. 6 is a flow chart showing a communication method based on a side link according to an exemplary embodiment. As shown in Fig. 6 , the communication method based on a side link is executed by a second device, and includes the following steps.

在步骤S51中，发送第二配置信息。In step S51, the second configuration information is sent.

本公开实施例中，第二配置信息是由第二设备发送的、用于使第一设备确定用于波束测量的参考信号资源配置信息，参考信号资源配置信息用于确定第一设备进行sidelink波束测量所对应的参考信号资源信息。网络设备将发送第一配置信息，以使终端通过第一配置信息获取参考信号资源配置信息，并通过参考信号资源配置信息确定进行sidelink波束测量所对应的参考信号资源信息。In the embodiment of the present disclosure, the second configuration information is sent by the second device and used to enable the first device to determine reference signal resource configuration information for beam measurement, and the reference signal resource configuration information is used to determine that the first device performs sidelink beam Reference signal resource information corresponding to the measurement. The network device will send the first configuration information, so that the terminal obtains reference signal resource configuration information through the first configuration information, and determines reference signal resource information corresponding to performing sidelink beam measurement through the reference signal resource configuration information.

示例的，第二配置信息例如可以是通过用于终端之间的交互的PC5 RRC来承载。第二配置信息例如还可以是通过用于终端之间的PSSCH来承载，例如通过PSSCH上的SL MACCE来承载。第二配置信息例如还可以是通过用于终端之间的物理侧链路控制信道PSCCH来承载，例如通过PSCCH上的sidelink控制信息SCI来承载。Exemplarily, the second configuration information may be carried by, for example, PC5 RRC used for interaction between terminals. For example, the second configuration information may also be carried by a PSSCH used between terminals, such as by an SL MACCE on the PSSCH. The second configuration information may also be carried, for example, through a physical sidelink control channel PSCCH used between terminals, for example, through sidelink control information SCI on the PSCCH.

本公开实施例提供的方法，参考信号资源配置信息包括参考信号资源位置信息和参考信号资源集合对应的重复状态中的至少一项。In the method provided by the embodiments of the present disclosure, the reference signal resource configuration information includes at least one item of reference signal resource position information and a repetition state corresponding to the reference signal resource set.

一示例中，参考信号资源信息包括参考信号资源位置信息。In an example, the reference signal resource information includes reference signal resource location information.

另一示例中，参考信号资源信息包括参考信号资源集合对应的重复状态。In another example, the reference signal resource information includes a repetition state corresponding to the reference signal resource set.

另一示例中，参考信号资源信息同时包括参考信号资源位置信息和参考信号资源集合对应的重复状态。In another example, the reference signal resource information includes reference signal resource location information and a repetition state corresponding to the reference signal resource set.

上述实施例中，参考信号资源集合包括多个参考信号资源，重复状态用于指示多个参考信号资源各自对应的波束是否相同。In the above embodiment, the reference signal resource set includes multiple reference signal resources, and the repetition state is used to indicate whether beams corresponding to the multiple reference signal resources are the same.

示例的，参考信号资源集合对应的重复状态包括开启(on)状态和关闭(off)状态。当参考信号资源集合对应的重复状态为开启(on)状态时，参考信号资源集合内的各个参考信号资源对应同一的波束。当参考信号资源集合对应的重复状态为开启(off)状态时，参考信号资源集合内的各个参考信号资源对应不同的波束。Exemplarily, the repeated states corresponding to the reference signal resource set include an on state and an off state. When the repetition state corresponding to the reference signal resource set is on (on), each reference signal resource in the reference signal resource set corresponds to the same beam. When the repetition state corresponding to the reference signal resource set is an on (off) state, each reference signal resource in the reference signal resource set corresponds to a different beam.

本公开实施例提供的方法，资源位置信息可以理解为与参考信号的时频资源位置相关的信息。示例的，资源位置信息例如可以包括至少一个时域起始符号位置、至少一个子载波位置、至少一个端口数、参考信号资源数、参考信号资源占用的slot数、参考信号资源占用的mini-slot数、参考信号资源占用的时间单元参考信号资源占用的起始资源块位置、参考信号资源占用的资源块数量、参考信号资源标识、以及参考信号资源集合标识之一或组合。其中，参考信号资源占用的时间单元可以是slot或mini-slot。In the method provided by the embodiments of the present disclosure, the resource location information may be understood as information related to the time-frequency resource location of the reference signal. For example, the resource location information may include at least one time domain start symbol location, at least one subcarrier location, at least one port number, number of reference signal resources, number of slots occupied by reference signal resources, and mini-slot occupied by reference signal resources One or a combination of number, time unit occupied by reference signal resources, starting resource block position occupied by reference signal resources, number of resource blocks occupied by reference signal resources, reference signal resource identifier, and reference signal resource set identifier. Wherein, the time unit occupied by the reference signal resource may be slot or mini-slot.

其中，mini-slot是相对于以slot为粒度而言。以slot为粒度进行调度时，占用的符号数最小可以为3。以mini-slot为粒度进行调度时，占用的符号数最小可以为1或2。而且一个slot可以包含多个mini-slot的调度单元，一个mini-slot还可以占用两个相邻slot的符号。Among them, mini-slot is relative to the granularity of slot. When the slot is used as the granularity for scheduling, the minimum number of occupied symbols can be 3. When scheduling at the granularity of mini-slot, the minimum number of occupied symbols can be 1 or 2. Moreover, a slot can contain multiple mini-slot scheduling units, and a mini-slot can also occupy symbols of two adjacent slots.

本公开实施例提供的方法，资源位置信息可以包括参考信号时域起始符号位置信息(例如sl-CSI-RS-FirstSymbol)，以及包括参考信号频域资源位置信息(例如sl-CSI-RS-FreqAllocation)。其中，sl-CSI-RS-FirstSymbol用于指示参考信号资源对应的时域起始符号位置，sl-CSI-RS-FreqAllocation用于指示参考信号资源对应的RE位置以及端口数。In the method provided by the embodiments of the present disclosure, the resource position information may include reference signal time domain start symbol position information (such as sl-CSI-RS-FirstSymbol), and reference signal frequency domain resource position information (such as sl-CSI-RS-FirstSymbol) FreqAllocation). Wherein, sl-CSI-RS-FirstSymbol is used to indicate the time-domain start symbol position corresponding to the reference signal resource, and sl-CSI-RS-FreqAllocation is used to indicate the RE position and port number corresponding to the reference signal resource.

本公开实施例中，参考信号资源配置信息包括参考信号资源位置信息。一实施方式中，可以通过参考信号资源位置信息配置sl-CSI-RS-FirstSymbol和sl-CSI-RS-FreqAllocation。并且，示例的，资源位置信息可以包括一个或多个sl-CSI-RS-FirstSymbol，以及包括一个或多个sl-CSI-RS-FreqAllocation。In the embodiment of the present disclosure, the reference signal resource configuration information includes reference signal resource location information. In one embodiment, the sl-CSI-RS-FirstSymbol and sl-CSI-RS-FreqAllocation can be configured through reference signal resource location information. And, for example, the resource location information may include one or more sl-CSI-RS-FirstSymbols, and one or more sl-CSI-RS-FreqAllocation.

一实施方式中，资源位置信息包括多个sl-CSI-RS-FirstSymbol以及多个sl-CSI-RS-FreqAllocation。其中，多个sl-CSI-RS-FirstSymbol用于确定多个参考信号资源各自分别对应的时域起始符号位置l，多个sl-CSI-RS-FreqAllocation用于确定多个参考信号资源各自分别对应的RE位置以及端口数。In one embodiment, the resource location information includes multiple sl-CSI-RS-FirstSymbols and multiple sl-CSI-RS-FreqAllocations. Among them, multiple sl-CSI-RS-FirstSymbols are used to determine the time-domain start symbol positions 1 respectively corresponding to multiple reference signal resources, and multiple sl-CSI-RS-FreqAllocation are used to determine multiple reference signal resources respectively Corresponding RE position and number of ports.

其中，多个参考信号资源与多个sl-CSI-RS-FirstSymbol之间是一一对应的关系，多个参考信号资源与多个sl-CSI-RS-FreqAllocation之间也是一一对应的关系。该情况下，相当于为多个参考信号资源中的每个参考信号资源，分别独立配置了sl-CSI-RS-FirstSymbol和sl-CSI-RS-FreqAllocation。也即，为多个参考信号资源中的每个参考信号资源，分别独立配置了时域起始符号位置、RE位置以及端口数。There is a one-to-one correspondence between multiple reference signal resources and multiple sl-CSI-RS-FirstSymbols, and there is also a one-to-one correspondence between multiple reference signal resources and multiple sl-CSI-RS-FreqAllocations. In this case, it is equivalent to configuring sl-CSI-RS-FirstSymbol and sl-CSI-RS-FreqAllocation independently for each of the plurality of reference signal resources. That is, for each reference signal resource among the plurality of reference signal resources, the time-domain start symbol position, RE position, and port number are independently configured.

示例的，通过sl-CSI-RS-FirstSymbol确定时域起始符号位置的方式，可以适用于一个slot包含一个CSI-RS资源的情况，也可以适用于一个slot包含多个CSI-RS资源的情况。在此基础上，为使终端可以进一步明确slot包含CSI-RS资源的具体情况，第二设备可进一步使用资源位置信息，通过显式指示方式或默认规则，对slot包含CSI-RS资源的情况做出指示。For example, the method of determining the start symbol position in the time domain through sl-CSI-RS-FirstSymbol can be applied to the case where a slot contains one CSI-RS resource, and can also be applied to the case where a slot contains multiple CSI-RS resources . On this basis, in order to enable the terminal to further clarify the specific situation that the slot contains CSI-RS resources, the second device can further use the resource location information to make a decision on the situation that the slot contains CSI-RS resources through an explicit indication method or a default rule. give directions.

一示例中，可以通过资源位置信息确定每个CSI-RS资源对应的slot位置，相当于资源以显式指示方式对slot包含CSI-RS资源的情况进行了指示。在此基础上，资源位置信息可以用于确定多个参考信号资源各自分别对应的slot位置，第一设备可基于资源位置信息确定每个CSI-RS资源对应的slot位置。In an example, the slot position corresponding to each CSI-RS resource may be determined through the resource position information, which is equivalent to the fact that the resource indicates that the slot contains the CSI-RS resource in an explicit manner. On this basis, the resource location information may be used to determine slot locations corresponding to the multiple reference signal resources, and the first device may determine the slot location corresponding to each CSI-RS resource based on the resource location information.

另一示例中，可以通过资源位置信息对CSI-RS资源所占用的时间单元做出指示。例如，资源位置信息可以用于指示多个参考信号资源占用的slot数，第一设备可基于资源位置信息确定多个参考信号资源占用的slot数。此外，资源位置信息还可以用于指示多个参考信号资源占用的mini-slot数，第一设备可基于资源位置信息确定多个参考信号资源占用的mini-slot数。In another example, the time unit occupied by the CSI-RS resource may be indicated through resource location information. For example, the resource location information may be used to indicate the number of slots occupied by multiple reference signal resources, and the first device may determine the number of slots occupied by multiple reference signal resources based on the resource location information. In addition, the resource location information may also be used to indicate the number of mini-slots occupied by multiple reference signal resources, and the first device may determine the number of mini-slots occupied by multiple reference signal resources based on the resource location information.

其中，不同参考信号资源可以对应相同或不同的slot位置。Wherein, different reference signal resources may correspond to the same or different slot positions.

例如，当资源位置信息用于确定多个参考信号资源各自分别对应的slot位置时，对于对应相同slot位置的参考信号资源而言，不同参考信号资源对应的时域起始符号位置需要不同。而对于对应不同slot位置的参考信号资源而言，不同参考信号资源对应的时域起始符号位置可以相同或不同。又例如，当资源位置信息用于确定多个参考信号资源占用的slot数时，不同CSI-RS资源对应的slot位置不同。又例如，当资源位置信息用于确定多个参考信号资源占用的mini-slot数时，资源位置信息指示基于mini-slot的传输，不同CSI-RS资源对应的slot位置可以相同或不同。For example, when the resource position information is used to determine slot positions corresponding to multiple reference signal resources, for reference signal resources corresponding to the same slot position, the time-domain start symbol positions corresponding to different reference signal resources need to be different. For reference signal resources corresponding to different slot positions, the time-domain start symbol positions corresponding to different reference signal resources may be the same or different. For another example, when the resource position information is used to determine the number of slots occupied by multiple reference signal resources, slot positions corresponding to different CSI-RS resources are different. For another example, when the resource location information is used to determine the number of mini-slots occupied by multiple reference signal resources, the resource location information indicates mini-slot-based transmission, and slot locations corresponding to different CSI-RS resources may be the same or different.

本公开实施例提供的方法，参考信号可以是sidelink CSI-RS。以sidelink CSI-RS为例，后续我们简称为CSI-RS。每个CSI-RS资源需要占用M个符号位，且CSI-RS资源前需要配置AGC调整，需要在CSI-RS资源所占用的符号位前额外占用用于AGC的一个符号位。换言之，对于一个CSI-RS资源的配置，需要占用M+1个符号位。此外，slot本身需要预留一个符号为gap，因此，当一个CSI-RS资源的配置需要M个符号位且M＝1时，且slot支持配置的符号位数为N(示例的，N为正整数)时，一个slot可配置的CSI-RS资源的数量为N/2-1。例如，当slot支持12个符号位的配置时，一个slot可以包含最多5个CSI-RS资源。当slot支持14个符号位的配置时，一个slot可以包含最多6个CSI-RS。当一个slot的符号位被占满时，配置后续的CSI-RS资源配置时，则继续占用连续slot中的下一个slot。In the method provided by the embodiments of the present disclosure, the reference signal may be a sidelink CSI-RS. Taking sidelink CSI-RS as an example, we will refer to it as CSI-RS for short. Each CSI-RS resource needs to occupy M sign bits, and AGC adjustment needs to be configured before the CSI-RS resource, and an additional sign bit for AGC needs to be occupied before the sign bit occupied by the CSI-RS resource. In other words, for the configuration of one CSI-RS resource, M+1 sign bits need to be occupied. In addition, the slot itself needs to reserve a symbol as a gap. Therefore, when the configuration of a CSI-RS resource requires M sign bits and M=1, and the number of sign bits supported by the slot is N (in the example, N is positive integer), the number of configurable CSI-RS resources for one slot is N/2-1. For example, when the slot supports the configuration of 12 sign bits, a slot can contain up to 5 CSI-RS resources. When the slot supports the configuration of 14 sign bits, a slot can contain a maximum of 6 CSI-RSs. When the sign bit of a slot is fully occupied, when configuring the subsequent CSI-RS resource configuration, continue to occupy the next slot in the continuous slots.

一实施方式中，资源位置信息包括多个sl-CSI-RS-FirstSymbol以及单一sl-CSI-RS-FreqAllocation。其中，多个sl-CSI-RS-FirstSymbol用于确定多个参考信号资源各自分别对应的时域起始符号位置，单一sl-CSI-RS-FreqAllocation用于确定多个参考信号资源对应的RE位置以及端口数。In one embodiment, the resource location information includes multiple sl-CSI-RS-FirstSymbols and a single sl-CSI-RS-FreqAllocation. Among them, multiple sl-CSI-RS-FirstSymbols are used to determine the time-domain start symbol positions corresponding to multiple reference signal resources, and a single sl-CSI-RS-FreqAllocation is used to determine the RE positions corresponding to multiple reference signal resources and the number of ports.

其中，多个参考信号资源与多个sl-CSI-RS-FirstSymbol之间是一一对应的关系。该情况下，相当于为多个参考信号资源中的每个参考信号资源，分别独立配置了sl-CSI-RS-FirstSymbol，且不同参考信号资源相比，时域起始符号位置可以相同或不同。此外，资源位置信息还包括用于确定多个参考信号资源对应RE位置以及端口数的单一sl-CSI-RS-FreqAllocation，该单一sl-CSI-RS-FreqAllocation可以理解为多个参考信号资源共用的sl-CSI-RS-FreqAllocation。换言之，多个参考信号资源各自对应了同样的sl-CSI-RS-FreqAllocation。该情况下，每个参考信号资源对应的RE位置和端口数是一样的。There is a one-to-one correspondence between multiple reference signal resources and multiple sl-CSI-RS-FirstSymbols. In this case, it is equivalent to configuring sl-CSI-RS-FirstSymbol independently for each of the multiple reference signal resources, and compared with different reference signal resources, the position of the start symbol in the time domain can be the same or different . In addition, the resource location information also includes a single sl-CSI-RS-FreqAllocation for determining the RE location and the number of ports corresponding to multiple reference signal resources. The single sl-CSI-RS-FreqAllocation can be understood as a shared sl-CSI-RS-FreqAllocation. In other words, the multiple reference signal resources each correspond to the same sl-CSI-RS-FreqAllocation. In this case, the RE positions and port numbers corresponding to each reference signal resource are the same.

示例的，通过sl-CSI-RS-FirstSymbol来确定时域起始符号位置的方式，可以适用于一个slot包含一个CSI-RS资源的情况，也可以适用于一个slot包含多个CSI-RS资源的情况。在此基础上，为使终端可以进一步明确slot包含CSI-RS资源的具体情况，可使用资源位置信息，通过显式指示方式或默认规则，对slot包含CSI-RS资源的情况做出指示。其中，由于通过资源位置信息指示CSI-RS资源所占用的时间单元的实现方式，本公开上述实施例中已经进行了说明，因此具体实现方式可直接参考上述实施例，本公开在此不做赘述。For example, the method of determining the start symbol position in the time domain through sl-CSI-RS-FirstSymbol can be applied to the case where a slot contains one CSI-RS resource, and can also be applied to the case where a slot contains multiple CSI-RS resources Condition. On this basis, in order to enable the terminal to further clarify the specific situation that the slot contains CSI-RS resources, the resource location information can be used to indicate the situation that the slot contains CSI-RS resources through an explicit indication method or a default rule. Wherein, since the implementation of indicating the time unit occupied by the CSI-RS resources through the resource location information has been described in the above-mentioned embodiments of the present disclosure, the specific implementation may directly refer to the above-mentioned embodiments, and the present disclosure will not repeat them here. .

一实施方式中，资源位置信息包括单一sl-CSI-RS-FirstSymbol以及多个sl-CSI-RS-FreqAllocation。其中，单一sl-CSI-RS-FirstSymbol用于确定多个参考信号资源对应的时域起始符号位置的，多个sl-CSI-RS-FreqAllocation用于确定多个参考信号资源各自分别对应的RE位置以及端口数。In one embodiment, the resource location information includes a single sl-CSI-RS-FirstSymbol and multiple sl-CSI-RS-FreqAllocations. Among them, a single sl-CSI-RS-FirstSymbol is used to determine the time-domain start symbol positions corresponding to multiple reference signal resources, and multiple sl-CSI-RS-FreqAllocation are used to determine REs corresponding to multiple reference signal resources respectively location and number of ports.

例如，资源位置信息包括单一sl-CSI-RS-FirstSymbol以及多个sl-CSI-RS-FreqAllocation，并包括slot数量和/或参考信号资源数量。其中，多个参考信号资源中不同参考信号资源对应相同时域起始符号位置。而多个参考信号资源与多个sl-CSI-RS-FreqAllocation之间是一一对应的关系，相当于为多个参考信号资源中的每个参考信号资源，分别独立配置了和sl-CSI-RS-FreqAllocation。也即，为多个参考信号资源中的每个参考信号资源，分别独立配置了RE位置以及端口数。此时，不同CSI-RS资源对应不同slot，但对应相同时域起始符号位置。并且，不同CSI-RS资源对应的RE位置和端口数可以相同或不同。For example, the resource location information includes a single sl-CSI-RS-FirstSymbol and multiple sl-CSI-RS-FreqAllocations, and includes the number of slots and/or the number of reference signal resources. Wherein, different reference signal resources among the multiple reference signal resources correspond to the same time-domain start symbol position. There is a one-to-one correspondence between multiple reference signal resources and multiple sl-CSI-RS-FreqAllocations, which is equivalent to independently configuring and sl-CSI-RS-FreqAllocation for each of the multiple reference signal resources. RS-FreqAllocation. That is, for each reference signal resource among the plurality of reference signal resources, the position of RE and the number of ports are independently configured. At this time, different CSI-RS resources correspond to different slots, but correspond to the same start symbol position in the time domain. In addition, RE positions and port numbers corresponding to different CSI-RS resources may be the same or different.

又例如，资源位置信息包括单一sl-CSI-RS-FirstSymbol以及多个sl-CSI-RS-FreqAllocation，并包括mini-slot数量和/或参考信号资源数量。其中，多个参考信号资源与多个sl-CSI-RS-FreqAllocation之间是一一对应的关系，相当于为多个参考信号资源中的每个参考信号资源，分别独立配置了和sl-CSI-RS-FreqAllocation。也即，为多个参考信号资源中的每个参考信号资源，分别独立配置了RE位置以及端口数，不同CSI-RS资源对应的RE位置和端口数可以相同或不同。并且，多个参考信号资源中不同参考信号资源对应的时域起始符号位置为首个mini-slot所对应符号位置，多个mini-slot中相邻mini-slot之间具有设定数量符号间隔，且不同参考信号资源对应相同或不同的RE位置和端口数。For another example, the resource location information includes a single sl-CSI-RS-FirstSymbol and multiple sl-CSI-RS-FreqAllocations, and includes the number of mini-slots and/or the number of reference signal resources. Among them, there is a one-to-one correspondence relationship between multiple reference signal resources and multiple sl-CSI-RS-FreqAllocations, which is equivalent to independently configuring and sl-CSI for each reference signal resource among the multiple reference signal resources. -RS-FreqAllocation. That is, for each reference signal resource among the plurality of reference signal resources, RE positions and port numbers are configured independently, and the RE positions and port numbers corresponding to different CSI-RS resources may be the same or different. In addition, the time-domain starting symbol positions corresponding to different reference signal resources in the multiple reference signal resources are the symbol positions corresponding to the first mini-slot, and there is a set number of symbol intervals between adjacent mini-slots in the multiple mini-slots, And different reference signal resources correspond to the same or different RE positions and port numbers.

示例的，参考信号可以是sidelink CSI-RS。以sidelink CSI-RS为例，后面简称CSI-RS。每个CSI-RS资源需要占用M个符号位，且CSI-RS资源前需要配置自动增益控制(automatic gain control，AGC)调整，需要在CSI-RS资源所占用的符号位前额外占用用于AGC的一个符号位。换言之，对于一个CSI-RS资源的配置，需要占用M+1个符号位。此外，slot本身需要预留一个符号为gap，因此，当一个CSI-RS资源的配置需要占用M+1个符号位且M＝1时，且slot支持配置的符号位数为N(示例的，N为正整数)时，一个slot可配置的CSI-RS资源的数量为N/2-1。例如，当slot支持12个符号位的配置时，一个slot可以包含最多5个CSI-RS资源。当slot支持14个符号位的配置时，一个slot可以包含最多6个CSI-RS资源。当一个slot的符号位被占满时，配置后续的CSI-RS资源配置时，则继续占用连续slot中的下一个slot。Exemplarily, the reference signal may be a sidelink CSI-RS. Take the sidelink CSI-RS as an example, hereinafter referred to as CSI-RS. Each CSI-RS resource needs to occupy M sign bits, and automatic gain control (automatic gain control, AGC) adjustment needs to be configured before the CSI-RS resource, and it needs to be additionally occupied before the sign bit occupied by the CSI-RS resource for AGC A sign bit of . In other words, for the configuration of one CSI-RS resource, M+1 sign bits need to be occupied. In addition, the slot itself needs to reserve a symbol as a gap. Therefore, when the configuration of a CSI-RS resource needs to occupy M+1 symbol bits and M=1, and the number of symbol bits supported by the slot is N (for example, When N is a positive integer), the number of CSI-RS resources that can be configured in one slot is N/2-1. For example, when the slot supports the configuration of 12 sign bits, a slot can contain up to 5 CSI-RS resources. When the slot supports the configuration of 14 sign bits, one slot can contain a maximum of 6 CSI-RS resources. When the sign bit of a slot is fully occupied, when configuring the subsequent CSI-RS resource configuration, continue to occupy the next slot in the continuous slots.

当然，参考信号资源占用一个符号位仅是一可行实施例，参考信号资源实际占用的符号数并不限于此。相应的，对于一个slot而言，其可支持的参考信号资源的配置数量，是可以通过参考信号资源实际占用的符号数，以及slot自身的符号数限制(示例的，符号数限制可以理解为对参考信号资源的配置数量产生影响的因素，例如可以是上述涉及的预留gap位)做出相应调整的。Of course, it is only a feasible embodiment that the reference signal resources occupy one symbol bit, and the number of symbols actually occupied by the reference signal resources is not limited thereto. Correspondingly, for a slot, the configuration quantity of reference signal resources that it can support is the number of symbols that can be actually occupied by reference signal resources, and the limitation of the number of symbols of the slot itself (for example, the limitation of the number of symbols can be understood as Factors affecting the configuration quantity of reference signal resources, for example, may be adjusted accordingly by the above-mentioned reserved gap bits).

此外，对于资源位置信息包括单一sl-CSI-RS-FirstSymbol、单一sl-CSI-RS-FirstSymbol以及mini-slot数量和/或参考信号资源数量的情况，第一个mini-slot的时域起始位置可以通过sl-CSI-RS-FirstSymbol确定，而后续的mini-slot的时域起始位置则是基于第一个mini-slot的时域起始位置陆续确定的。例如，第二个mini-slot的时域起始位置，是基于第一个mini-slot的时域结束位置确定的。第三个mini-slot的时域起始位置，是基于第二个mini-slot的时域结束位置确定的。其中，以通过第一个mini-slot的时域结束位置确定第二个mini-slot的时域起始位置为例，第一个mini-slot的时域结束位置与第二个mini-slot的时域起始位置之间通过AGC占用的符号进行间隔，在第一个mini-slot的时域结束位置的基础上，补入AGC所占用的符号数，就可以得到第二个mini-slot的时域起始位置。In addition, when the resource location information includes a single sl-CSI-RS-FirstSymbol, a single sl-CSI-RS-FirstSymbol and the number of mini-slots and/or the number of reference signal resources, the time domain start of the first mini-slot The position can be determined by sl-CSI-RS-FirstSymbol, and the time-domain starting positions of subsequent mini-slots are successively determined based on the time-domain starting position of the first mini-slot. For example, the start position of the time domain of the second mini-slot is determined based on the end position of the time domain of the first mini-slot. The start position of the time domain of the third mini-slot is determined based on the end position of the time domain of the second mini-slot. Among them, taking the time domain end position of the first mini-slot to determine the time domain start position of the second mini-slot as an example, the time domain end position of the first mini-slot is the same as the second mini-slot The start position of the time domain is separated by the symbols occupied by AGC. On the basis of the end position of the time domain of the first mini-slot, the number of symbols occupied by AGC is added to obtain the second mini-slot. Time domain start position.

一实施方式中，资源位置信息包括单一sl-CSI-RS-FirstSymbol以及单一sl-CSI-RS-FreqAllocation，并包括slot数量和/或参考信号资源数量。In one embodiment, the resource location information includes a single sl-CSI-RS-FirstSymbol and a single sl-CSI-RS-FreqAllocation, and includes the number of slots and/or the number of reference signal resources.

其中，单一sl-CSI-RS-FirstSymbol用于确定多个参考信号资源对应的时域起始符号位置，单一sl-CSI-RS-FreqAllocation用于确定多个参考信号资源对应的RE位置以及端口数。Among them, a single sl-CSI-RS-FirstSymbol is used to determine the time-domain start symbol positions corresponding to multiple reference signal resources, and a single sl-CSI-RS-FreqAllocation is used to determine the RE positions and port numbers corresponding to multiple reference signal resources .

其中，多个参考信号资源中不同参考信号资源对应相同时域起始符号位置，且同一slot内的参考信号资源对应相同RE位置和端口数。换言之，对于资源位置信息包括用于确定多个参考信号资源对应时域起始符号位置的单一sl-CSI-RS-FirstSymbol，以及包括用于确定多个参考信号资源对应RE位置以及端口数的单一sl-CSI-RS-FreqAllocation，并包括slot数量和/或参考信号数量的情况。多个slot保持连续或不连续，CSI-RS资源的数量与slot数量保持一致。此时，不同CSI-RS资源对应不同slot，但不同CSI-RS资源对应了相同的时域起始符号位置、相同的RE位置、以及相同的端口数。Among the multiple reference signal resources, different reference signal resources correspond to the same time-domain start symbol position, and the reference signal resources in the same slot correspond to the same RE position and port number. In other words, the resource location information includes a single sl-CSI-RS-FirstSymbol used to determine the position of the start symbol in the time domain corresponding to multiple reference signal resources, and a single sl-CSI-RS-FreqAllocation, and includes the number of slots and/or the number of reference signals. Multiple slots are continuous or discontinuous, and the number of CSI-RS resources is consistent with the number of slots. At this time, different CSI-RS resources correspond to different slots, but different CSI-RS resources correspond to the same time-domain start symbol position, the same RE position, and the same number of ports.

本公开实施例提供的方法，当资源位置信息包括单一sl-CSI-RS-FirstSymbol、单一sl-CSI-RS-FreqAllocation以及slot数量和/或参考信号资源数量时，资源位置信息适用于基于slot的配置。In the method provided by the embodiments of the present disclosure, when the resource location information includes a single sl-CSI-RS-FirstSymbol, a single sl-CSI-RS-FreqAllocation, and the number of slots and/or the number of reference signal resources, the resource location information is suitable for slot-based configuration.

一实施方式中，资源位置信息包括单一sl-CSI-RS-FirstSymbol以及单一sl-CSI-RS-FreqAllocation，并包括mini-slot数量和/或参考信号资源数量。In one embodiment, the resource location information includes a single sl-CSI-RS-FirstSymbol and a single sl-CSI-RS-FreqAllocation, and includes the number of mini-slots and/or the number of reference signal resources.

其中，单一sl-CSI-RS-FirstSymbol用于确定多个参考信号资源对应的时域起始符号位置，单一sl-CSI-RS-FreqAllocation用于确定多个参考信号资源对应的RE位置以及端口数。Among them, a single sl-CSI-RS-FirstSymbol is used to determine the time-domain start symbol positions corresponding to multiple reference signal resources, and a single sl-CSI-RS-FreqAllocation is used to determine the RE positions and port numbers corresponding to multiple reference signal resources .

其中，多个参考信号资源中不同参考信号资源对应的时域起始符号位置为首个mini-slot所对应符号位置，多个mini-slot中相邻mini-slot之间具有设定数量符号间隔，且不同参考信号资源对应相同RE位置和端口数。Wherein, the time-domain starting symbol position corresponding to different reference signal resources in the multiple reference signal resources is the symbol position corresponding to the first mini-slot, and there is a set number of symbol intervals between adjacent mini-slots in the multiple mini-slots, And different reference signal resources correspond to the same RE position and number of ports.

示例的，参考信号可以是sidelink CSI-RS。以sidelink CSI-RS为例，后面简称CSI-RS。每个CSI-RS资源需要占用M个符号位，且CSI-RS资源前需要配置自动增益控制(automatic gain control，AGC)调整，需要在CSI-RS资源所占用的符号位前额外占用用于AGC的一个符号位。换言之，对于一个CSI-RS资源的配置，需要占用M+1个符号位。此外，slot本身需要预留一个符号为gap，因此，当一个CSI-RS资源的配置需要占用M+1个符号位且M＝1时，且slot支持配置的符号位数为N(示例的，N为正整数)时，一个slot可配置的CSI-RS资源的数量为N/2-1。例如，当slot支持12个符号位的配置时，一个slot可以包含最多5个CSI-RS资源。当slot支持14个符号位的配置时，一个slot可以包含最多6个CSI-RS资源。当一个slot的符号位被占满时，配置后续的CSI-RS资源配置时，则继续占用连续slot中的下一个slot。Exemplarily, the reference signal may be a sidelink CSI-RS. Take the sidelink CSI-RS as an example, hereinafter referred to as CSI-RS. Each CSI-RS resource needs to occupy M sign bits, and automatic gain control (automatic gain control, AGC) adjustment needs to be configured before the CSI-RS resource, and it needs to be additionally occupied before the sign bit occupied by the CSI-RS resource for AGC A sign bit of . In other words, for the configuration of one CSI-RS resource, M+1 sign bits need to be occupied. In addition, the slot itself needs to reserve a symbol as a gap. Therefore, when the configuration of a CSI-RS resource needs to occupy M+1 symbol bits and M=1, and the number of symbol bits supported by the slot is N (for example, When N is a positive integer), the number of CSI-RS resources that can be configured in one slot is N/2-1. For example, when the slot supports the configuration of 12 sign bits, a slot can contain up to 5 CSI-RS resources. When the slot supports the configuration of 14 sign bits, one slot can contain a maximum of 6 CSI-RS resources. When the sign bit of a slot is fully occupied, when configuring the subsequent CSI-RS resource configuration, continue to occupy the next slot in the continuous slots.

当然，参考信号资源占用一个符号位仅是一可行实施例，参考信号资源实际占用的符号数并不限于此。相应的，对于一个slot而言，其可支持的参考信号资源的配置数量，是可以通过参考信号资源实际占用的符号数，以及slot自身的符号数限制(示例的，符号数限制可以理解为对参考信号资源的配置数量产生影响的因素，例如可以是上述涉及的预留gap位)做出相应调整的。Of course, it is only a feasible embodiment that the reference signal resources occupy one symbol bit, and the number of symbols actually occupied by the reference signal resources is not limited thereto. Correspondingly, for a slot, the configuration quantity of reference signal resources that it can support is the number of symbols that can be actually occupied by reference signal resources, and the limitation of the number of symbols of the slot itself (for example, the limitation of the number of symbols can be understood as Factors affecting the configuration quantity of reference signal resources, for example, may be adjusted accordingly by the above-mentioned reserved gap bits).

此外，对于资源位置信息包括单一sl-CSI-RS-FirstSymbol、单一sl-CSI-RS-FirstSymbol以及mini-slot数量和/或参考信号资源数量的情况，第一个mini-slot的时域起始位置可以通过sl-CSI-RS-FirstSymbol确定，而后续的mini-slot的时域起始位置则是基于第一个mini-slot的时域起始位置陆续确定的。例如，第二个mini-slot的时域起始位置，是基于第一个mini-slot的时域结束位置确定的。第三个mini-slot的时域起始位置，是基于第二个mini-slot的时域结束位置确定的。其中，以通过第一个mini-slot的时域结束位置确定第二个mini-slot的时域起始位置为例，第一个mini-slot的时域结束位置与第二个mini-slot的时域起始位置之间通过AGC占用的符号进行间隔，在第一个mini-slot的时域结束位置的基础上，补入AGC所占用的符号数，就可以得到第二个mini-slot的时域起始位置。In addition, when the resource location information includes a single sl-CSI-RS-FirstSymbol, a single sl-CSI-RS-FirstSymbol and the number of mini-slots and/or the number of reference signal resources, the time domain start of the first mini-slot The position can be determined by sl-CSI-RS-FirstSymbol, and the time-domain starting positions of subsequent mini-slots are successively determined based on the time-domain starting position of the first mini-slot. For example, the start position of the time domain of the second mini-slot is determined based on the end position of the time domain of the first mini-slot. The start position of the time domain of the third mini-slot is determined based on the end position of the time domain of the second mini-slot. Among them, taking the time domain end position of the first mini-slot to determine the time domain start position of the second mini-slot as an example, the time domain end position of the first mini-slot is the same as the second mini-slot The start position of the time domain is separated by the symbols occupied by AGC. On the basis of the end position of the time domain of the first mini-slot, the number of symbols occupied by AGC is added to obtain the second mini-slot. Time domain start position.
