终端设备20和终端设备30可以D2D通信模式进行通信，在进行D2D通信时，终端设备20和终端设备30通过D2D链路即侧行链路(Sidelink，SL)直接进行通信。例如图1或者图2所示，终端设备20和终端设备30通过侧行链路直接进行通信。在图1中，终端设备20和终端设备30之间通过侧行链路通信，其传输资源是由网络设备分配的；在图2中，终端设备20和终端设备30之间通过侧行链路通信，其传输资源是由终端设备自主选取的，不需要网络设备分配传输资源。The terminal device 20 and the terminal device 30 can communicate in a D2D communication mode. During the D2D communication, the terminal device 20 and the terminal device 30 directly communicate through a D2D link, that is, a side link (Sidelink, SL). For example, as shown in FIG. 1 or FIG. 2 , the terminal device 20 and the terminal device 30 directly communicate through a side link.

It should be understood that, the embodiment of the present invention is mainly applied to the scenario of V2X communication, but may also be applied to any other D2D communication scenario, which is not limited in the embodiment of the present invention.

车联网中定义了两种传输模式，即传输模式3(mode 3)和传输模式4(mode 4)。模式3(简称为模式3)的终端设备的传输资源是由基站分配的，终端设备根据基站分配的资源在侧行链路上进行数据的发送；基站可以为终端设备分配单次传输的资源，也可以为终端设备分配半静态传输的资源。传输模式4(简称为模式4)的终端设备如果具备侦听能力，则采用侦听(sensing)和预留(reservation)的方式传输数据，如果不具备侦听能力，则在资源池中随机选取传输资源。具备侦听能力的终端设备在资源池中通过侦听的方式获取可用的资源集合，终端设备从该集合中随机选取一个资源进行数据传输。由于车联网系统中的业务具有周期性特征，因此终端设备通常采用半静态传输的方式，即终端设备选取一个传输资源后，就会在多个传输周期中持续的使用该资源，从而降低资源重选以及资源冲突的概率。终端设备会在本次传输的控制信息中携带预留下次传输资源的信息，从而使得其他终端设备可以通过检测该终端设备的控制信息判断这块资源是否被该终端设备预留和使用，达到降低资源冲突的目的。Two transmission modes are defined in the Internet of Vehicles, namely transmission mode 3 (mode 3) and transmission mode 4 (mode 4). The transmission resources of the terminal equipment in mode 3 (referred to as mode 3 for short) are allocated by the base station, and the terminal equipment transmits data on the sidelink according to the resources allocated by the base station; the base station can allocate resources for a single transmission to the terminal equipment, It is also possible to allocate resources for semi-static transmission to the terminal device. If the terminal device of transmission mode 4 (abbreviated as mode 4) has the ability to listen, it will transmit data in the form of sensing and reservation; if it does not have the ability to listen, it will randomly select from the resource pool transfer resources. A terminal device capable of listening obtains a set of available resources by listening in the resource pool, and the terminal device randomly selects a resource from the set for data transmission. Due to the periodic characteristics of the business in the Internet of Vehicles system, the terminal device usually adopts a semi-static transmission method, that is, after the terminal device selects a transmission resource, it will continue to use the resource in multiple transmission cycles, thereby reducing the resource load. selection and the probability of resource conflicts. The terminal device will carry the information about the resources reserved for the next transmission in the control information of this transmission, so that other terminal devices can judge whether this resource is reserved and used by the terminal device by detecting the control information of the terminal device, so as to achieve The purpose of reducing resource conflicts.

终端设备在数据传输过程中使用的上述各个资源池都是预先配置的或者网络配置的。当终端设备处于网络覆盖范围外的时候，只能使用预配置的资源池与其他终端设备进行数据传输。当终端设备处于网络覆盖范围内时，可以使用预配置的资源池与网络覆盖外的终端设备进行数据传输，也可以使用网络配置的资源池与网络覆盖内的其他终端设备进行数据传输。但是在NR中，对终端设备之间的数据传输性能提出了更高的要求，例如期望更高的吞吐量、更低的时延、更高的可靠性、更大的覆盖范围、更灵活的资源分配方式等。因此，除了预配置的这些资源池外，网络设备还可以为终端设备配置额外的资源池用于网络覆盖范围内的用户与网络覆盖范围外的终端设备进行数据传输。Each resource pool mentioned above used by the terminal device during data transmission is pre-configured or configured by the network. When the terminal device is outside the coverage of the network, it can only use the pre-configured resource pool to transmit data with other terminal devices. When the terminal device is within the coverage of the network, it can use the pre-configured resource pool for data transmission with the terminal device outside the network coverage, or use the resource pool configured by the network for data transmission with other terminal devices within the network coverage. However, in NR, higher requirements are placed on the performance of data transmission between terminal devices, such as expecting higher throughput, lower delay, higher reliability, larger coverage, more flexible Resource allocation methods, etc. Therefore, in addition to these pre-configured resource pools, the network device can also configure additional resource pools for the terminal device for data transmission between users within the network coverage and terminal devices outside the network coverage.

本申请实施例提出，第一终端设备通过发送第一侧行传输信道以指示资源池的资源池配置信息，使得第二终端设备能够接收指示该资源池配置信息的第一侧行传输信道，并获取该资源池的资源池配置信息，从而能够使用该资源池与第一终端设备进行通信。该资源池可以是除了预配置的资源池之外的其他额外的资源池，由于配置了额外的资源池，且第一终端设备可以将该额外的资源池的资源配置信息通知给其他的终端设备，更多的终端设备能够获得该资源池的信息并使用该资源池进行通信，因此一定程度上提高终端设备之间的数据传输性能。The embodiment of the present application proposes that the first terminal device sends the first sidelink transmission channel to indicate the resource pool configuration information of the resource pool, so that the second terminal device can receive the first sidelink transmission channel indicating the resource pool configuration information, and Resource pool configuration information of the resource pool is acquired, so that the resource pool can be used to communicate with the first terminal device. The resource pool may be an additional resource pool other than the preconfigured resource pool. Since the additional resource pool is configured, and the first terminal device may notify other terminal devices of the resource configuration information of the additional resource pool, More terminal devices can obtain the information of the resource pool and use the resource pool for communication, thus improving the performance of data transmission between terminal devices to a certain extent.

图3是本申请一个实施例的资源配置的方法的流程交互图。图3所示的方法可以由第一终端设备和第二终端设备执行，该第一终端设备例如可以为图2中所示的终端设备20或终端设备30，该第二终端设备例如可以为图2中所示的终端设备30或终端设备20。Fig. 3 is an interaction flow diagram of a method for resource allocation according to an embodiment of the present application. The method shown in FIG. 3 can be executed by a first terminal device and a second terminal device. The first terminal device can be, for example, the terminal device 20 or terminal device 30 shown in FIG. 2 , and the second terminal device can be, for example, the The terminal device 30 or the terminal device 20 shown in 2.

如图3所示，该资源配置的方法包括：As shown in Figure 3, the resource configuration method includes:

在310中，第一终端设备发送第一侧行传输信道。In 310, the first terminal device transmits a first sidelink transport channel.

在320中，第二终端设备接收该第一侧行传输信道。In 320, the second terminal device receives the first sidelink transmission channel.

其中，该第一侧行传输信道用于指示目标资源池的资源池配置信息，该目标资源池用于该第一终端设备与该第二终端设备之间进行通信。Wherein, the first sidelink transmission channel is used to indicate resource pool configuration information of a target resource pool, and the target resource pool is used for communication between the first terminal device and the second terminal device.

该目标资源池例如可以是上述的网络设备为终端设备配置的用于进行通信的额外的资源池。或者说，该目标资源池是除了预先配置的用于终端设备进行D2D通信的资源池之外的资源池。The target resource pool may be, for example, the above-mentioned additional resource pool configured by the network device for the terminal device for communication. In other words, the target resource pool is a resource pool other than the pre-configured resource pool for the terminal device to perform D2D communication.

在一个实施例中，该第一终端设备可以为小区内的终端设备，该第二终端设备可以为该小区之外的终端设备。这里，第二终端设备可以位于该第一终端设备所在小区之外且不属于其他小区，或者，第二终端设备可以位于其他小区即第二终端设备和第一终端设备所在的小区不同。In an embodiment, the first terminal device may be a terminal device within a cell, and the second terminal device may be a terminal device outside the cell. Here, the second terminal device may be located outside the cell where the first terminal device is located and not belong to other cells, or the second terminal device may be located in another cell, that is, the second terminal device and the first terminal device are located in different cells.

当该第一终端设备为小区内的终端设备时，第一终端设备可以从网络设备接收该目标资源池的资源池配置信息，从而在该目标资源池中进行数据传输。但是，如果该小区之外存在第二终端设备，那么由于该第二终端设备无法接收网络设备发送的该资源池配置信息，该第二终端设备则无法使用目标资源池进行数据传输。这时，根据本申请实施例的方法，第一终端设备可以向第二终端设备发送第一侧行传输信道，以指示该目标资源池的资源池配置信息，以使第二终端设备能够获知该目标资源池的存在，从而在进行数据传输时可以使用该目标资源池。When the first terminal device is a terminal device in a cell, the first terminal device may receive resource pool configuration information of the target resource pool from the network device, so as to perform data transmission in the target resource pool. However, if there is a second terminal device outside the cell, since the second terminal device cannot receive the resource pool configuration information sent by the network device, the second terminal device cannot use the target resource pool for data transmission. At this time, according to the method of the embodiment of the present application, the first terminal device may send the first sidelink transmission channel to the second terminal device to indicate the resource pool configuration information of the target resource pool, so that the second terminal device can know the resource pool configuration information of the target resource pool. Existence of the target resource pool, so that the target resource pool can be used during data transmission.

在一种实现方式中，该第一侧行传输信道可以为物理侧行链路广播信道(Physical Sidelink broadcast Channel，PSBCH)。该PSBCH中直接携带目标资源池的资源池配置信息。In an implementation manner, the first sidelink transmission channel may be a physical sidelink broadcast channel (Physical Sidelink broadcast Channel, PSBCH).

在一个实施例中，该目标资源池中的控制信道资源和数据信道资源之间的位置关系(或者也可以称为该目标资源池的结构)，包括该控制信道资源与该数据信道资源之间时分复用或者频分复用。In one embodiment, the positional relationship between the control channel resource and the data channel resource in the target resource pool (or also referred to as the structure of the target resource pool) includes the relationship between the control channel resource and the data channel resource Time division multiplexing or frequency division multiplexing.

进一步地，目标资源池的资源池配置信息中可以包括该位置关系的索引，例如，当包括索引1时，指示控制信道资源与该数据信道资源之间时分复用，当包括索引2时，指示控制信道资源与该数据信道资源之间频分复用。Further, the resource pool configuration information of the target resource pool may include an index of the location relationship, for example, whenindex 1 is included, it indicates time division multiplexing between the control channel resource and the data channel resource, and when index 2 is included, it indicates Frequency division multiplexing between the control channel resource and the data channel resource.

在车联网系统中，终端设备进行数据传输时，数据传输和相应的资源调度信息的传输可以采用频分复用(Frequency Division Multiplexing，FDM)或者时分复用(TimeDivision Multiplexing，TDM)的方式。In the Internet of Vehicles system, when the terminal device transmits data, the transmission of data transmission and corresponding resource scheduling information can adopt frequency division multiplexing (Frequency Division Multiplexing, FDM) or time division multiplexing (Time Division Multiplexing, TDM).

具体地，采用频分复用的方式时，用于传输资源调度信息的资源池与用于传输数据的资源池有两种配置方式，即频域相邻(adjacent)和非相邻(non-adjacent)的方式。Specifically, when frequency division multiplexing is adopted, the resource pool used to transmit resource scheduling information and the resource pool used to transmit data have two configuration modes, that is, adjacent in frequency domain (adjacent) and non-adjacent (non-adjacent). adjacent) way.

例如图6所示的频域相邻(adjacent)的情况，用于传输资源调度信息的控制信道资源，与该控制信道对应的数据信道资源在频域上是相邻的。整个系统带宽以子频带(子带)为粒度，每个子带包括多个连续的PRB，每个子带中的第一个PRB和第二个PRB为可以用来传输控制信道，其余的PRB为可以用来传输数据信道。数据信道资源与控制信道资源之间的是一一对应的，控制信道资源上传输的资源调度信息用于调度该控制信道资源对应的数据信道资源上的数据传输，并且该数据信道资源的起始位置由其对应的控制信道资源的位置决定。数据信道资源可以占用一个子带(例如，子帧2上的数据信道资源位于子带1内)，也可以跨过多个子带(例如，子帧4上的数据信道资源位于子带2和子带3内)。当数据信道资源占用多个子带时，数据信道资源在多个子带内是频域连续的，并可以占用其他子带内的控制信道资源，并且该数据信道资源对应的控制信道资源为该数据信道资源所在的第一个子带中的控制信道资源，例如，图6中的子帧4上的数据信道资源占用两个相邻的子带(子带2和子带3)，其对应的控制信道资源为其中的第一个子带(子带2)内的控制信道资源。For example, in the case of frequency domain adjacent (adjacent) shown in FIG. 6 , the control channel resource used to transmit resource scheduling information and the data channel resource corresponding to the control channel are adjacent in the frequency domain. The entire system bandwidth is granular in sub-bands (sub-bands), and each sub-band includes multiple consecutive PRBs. The first PRB and the second PRB in each sub-band can be used to transmit control channels, and the remaining PRBs can be Used to transmit data channels. There is a one-to-one correspondence between data channel resources and control channel resources. The resource scheduling information transmitted on the control channel resources is used to schedule data transmission on the data channel resources corresponding to the control channel resources, and the start of the data channel resources The location is determined by the location of its corresponding control channel resource. The data channel resource can occupy one subband (for example, the data channel resource on subframe 2 is located in subband 1), or it can span multiple subbands (for example, the data channel resource on subframe 4 is located in subband 2 and subband 1). 3). When the data channel resources occupy multiple subbands, the data channel resources are continuous in the frequency domain in multiple subbands, and can occupy control channel resources in other subbands, and the control channel resources corresponding to the data channel resources are the data channel resources The control channel resource in the first subband where the resource is located, for example, the data channel resource on subframe 4 in Figure 6 occupies two adjacent subbands (subband 2 and subband 3), and the corresponding control channel The resource is the control channel resource in the first subband (subband 2).

例如图7所示的频域非相邻(non-adjacent)的情况，控制信道资源和其对应的数据信道资源在频域上是不相邻的，数据信道资源和控制信道资源是独立配置的，但是数据信道资源的位置和控制信道资源的位置仍是一一对应的，控制信道资源上传输的资源调度信息用于调度该控制信道资源对应的数据信道资源上的数据传输，并且该数据信道资源的起始位置可由其对应的该控制信道资源的位置决定。数据信道资源可以占用一个子带(例如，子帧2上示出数据信道资源位于子带1)，也可以占用多个控制信道资源为该数据信道资源所在的第一个子带中的控制信道资源，例如，图7中的子帧4上的数据信道资源位于两个相邻的子带(子带2和子带3)，其对应的控制信道资源为第一个子带(子带2)内的控制信道资源。For example, in the non-adjacent case in the frequency domain shown in Figure 7, the control channel resources and their corresponding data channel resources are not adjacent in the frequency domain, and the data channel resources and control channel resources are configured independently , but the position of the data channel resource and the position of the control channel resource are still in one-to-one correspondence, the resource scheduling information transmitted on the control channel resource is used to schedule the data transmission on the data channel resource corresponding to the control channel resource, and the data channel resource The starting position of a resource may be determined by the corresponding position of the control channel resource. The data channel resource can occupy one subband (for example, the data channel resource shown in subframe 2 is located in subband 1), or multiple control channel resources can be occupied as the control channel in the first subband where the data channel resource is located. Resources, for example, the data channel resources on subframe 4 in Figure 7 are located in two adjacent subbands (subband 2 and subband 3), and the corresponding control channel resources are the first subband (subband 2) The control channel resources within.

当采用时分复用的方式时，例如图8所示，第一终端设备在子帧1的子带3上发送自己的控制信道资源即PSCCH，该控制信道资源对应的数据信道资源即PSSCH在子帧4的子带2上传输，该控制信道资源上承载的侧行链路控制信息(Sindlink Control Information，SCI)中可以携带其对应的数据信道资源的信息；第二终端设备在子帧1的子带4上发送自己的控制信道资源，该控制信道资源对应的数据信道资源在子帧5的子带3上传输，该控制信道资源上承载的SCI可以携带其对应的数据信道资源的信息；第三终端设备在子帧2的子带3上发送自己的控制信道资源，该控制信道资源对应的数据信道资源在子帧6的子带2上传输，该控制信道资源上承载的SCI可以携带其对应的数据信道资源的信息。When time division multiplexing is adopted, for example, as shown in FIG. 8, the first terminal device sends its own control channel resource, that is, PSCCH, on subband 3 ofsubframe 1, and the data channel resource corresponding to the control channel resource, that is, PSSCH, is in subband 3. Transmission on subband 2 of frame 4, the sidelink control information (Sindlink Control Information, SCI) carried on the control channel resource may carry the information of its corresponding data channel resource; the second terminal device insubframe 1 Send its own control channel resource on subband 4, and the data channel resource corresponding to the control channel resource is transmitted on subband 3 of subframe 5, and the SCI carried on the control channel resource can carry the information of its corresponding data channel resource; The third terminal device sends its own control channel resource on subband 3 of subframe 2, and the data channel resource corresponding to the control channel resource is transmitted on subband 2 of subframe 6, and the SCI carried on the control channel resource can carry Information about its corresponding data channel resources.

该目标资源池的资源池配置信息中可以携带该目标资源池中的控制信道资源和数据信道资源之间的该位置关系，第二终端设备接收该资源池配置信息后，就可以知道在该目标资源池中是按照图6或图7所示的方式，还是按照图8所示的方式传输控制信道和其对应的数据信道。The resource pool configuration information of the target resource pool may carry the positional relationship between the control channel resource and the data channel resource in the target resource pool. After receiving the resource pool configuration information, the second terminal device can know Whether the control channel and its corresponding data channel are transmitted in the resource pool according to the manner shown in FIG. 6 or FIG. 7 , or in the manner shown in FIG. 8 .

进一步地，当确定目标资源池的控制信道资源和数据信道资源的位置关系后，该资源池配置信息中还可以包括：该控制信道资源和该数据信道资源的频域资源相邻或者不相邻的信息，和/或，该控制信道资源和该数据信道资源的时域资源相邻或者不相邻的信息。Further, after determining the positional relationship between the control channel resource and the data channel resource of the target resource pool, the resource pool configuration information may also include: the frequency domain resources of the control channel resource and the data channel resource are adjacent or not information, and/or information about whether the time domain resources of the control channel resource and the data channel resource are adjacent or not.

例如，当确定采用频分复用的方式时，该资源池配置信息中包括该控制信道资源和该数据信道资源的频域资源相邻或者不相邻的信息。For example, when it is determined to adopt frequency division multiplexing, the resource pool configuration information includes information about whether the frequency domain resources of the control channel resource and the data channel resource are adjacent or not.

在一个实施例中，该目标资源池的解调参考信号(De Modulation ReferenceSignal，DMRS)图样的信息，包括该目标资源池的DMRS图样的索引。In one embodiment, the information of the demodulation reference signal (De Modulation Reference Signal, DMRS) pattern of the target resource pool includes the index of the DMRS pattern of the target resource pool.

例如，可以预配置多种DMRS图样，并且每个DMRS图样具有自己唯一的索引。该资源池配置信息中可以携带在该目标资源池中进行D2D通信时所使用的DMRS图样的索引。For example, multiple DMRS patterns can be preconfigured, and each DMRS pattern has its own unique index. The resource pool configuration information may carry the index of the DMRS pattern used when performing D2D communication in the target resource pool.

由于NR中可以支持不同的基本参数集，例如，在低频段(例如小于6GHz)的情况下，可以采用15k、30kHz的子载波间隔；在高频段(例如大于6GHz)的情况下，可以采用60k、120kHz的子载波间隔。因此，目标资源池的资源池配置信息中也需要携带基础参数集的信息。Since different basic parameter sets can be supported in NR, for example, in the case of low frequency bands (such as less than 6GHz), subcarrier spacing of 15k and 30kHz can be used; in the case of high frequency bands (such as greater than 6GHz), 60k can be used , 120kHz subcarrier spacing. Therefore, the resource pool configuration information of the target resource pool also needs to carry the information of the basic parameter set.

在一个实施例中，该基本参数集可以包括以下参数中的至少一种：子载波间隔、特定带宽下的子载波数目、物理资源块PRB中的子载波数、正交频分复用OFDM符号的长度、用于生成OFDM信号的傅里叶变换例如快速傅里叶变换(Fast Fourier Transform，简称“FFT”)或傅里叶逆变换例如快速逆傅里叶变换(Inverse Fast Fourier Transform，简称“IFFT”)的点数、传输时间间隔TTI中的OFDM符号数、特定时间长度内包含的TTI的个数和信号前缀的长度。In an embodiment, the basic parameter set may include at least one of the following parameters: subcarrier spacing, the number of subcarriers in a specific bandwidth, the number of subcarriers in a physical resource block PRB, an orthogonal frequency division multiplexing OFDM symbol The length of the Fourier transform used to generate OFDM signals such as Fast Fourier Transform (Fast Fourier Transform, referred to as "FFT") or inverse Fourier transform such as Fast Inverse Fourier Transform (Inverse Fast Fourier Transform, referred to as " IFFT"), the number of OFDM symbols in the transmission time interval TTI, the number of TTIs included in a specific time length, and the length of the signal prefix.

其中，子载波间隔可以指相邻子载波的频率间隔，例如15kHz，60kHz等；特定带宽下的子载波数目例如为每个可能的系统带宽对应的子载波数；PRB中包含的子载波数例如典型的可以是12的整数倍；TTI中包含的OFDM符号数例如典型的可以是14的整数倍；一定时间单位内包含的TTI数可以指1ms或者10ms的时间长度内包含的TTI数目；信号前缀长度例如为信号的循环前缀的时间长度，或者循环前缀使用常规(Cyclic Prefix，CP)还是使用扩展CP。Among them, the subcarrier spacing can refer to the frequency spacing of adjacent subcarriers, such as 15kHz, 60kHz, etc.; the number of subcarriers under a specific bandwidth is, for example, the number of subcarriers corresponding to each possible system bandwidth; the number of subcarriers contained in a PRB is, for example, Typically, it can be an integer multiple of 12; the number of OFDM symbols contained in a TTI, for example, can typically be an integer multiple of 14; the number of TTIs contained in a certain time unit can refer to the number of TTIs contained in a time length of 1ms or 10ms; the signal prefix The length is, for example, the time length of the cyclic prefix of the signal, or whether the cyclic prefix uses a regular (Cyclic Prefix, CP) or an extended CP.

考虑到每个载波上可以配置多个资源池，因此，更方便地，目标资源池的资源池配置信息中还可以携带该目标资源池的索引。例如，可以预配置多个候选的资源池(例如预配置多个候选资源池中每个候选资源池的上述资源配置信息)，每个候选资源池具有各自唯一的索引，根据该第一侧行传输信道上承载的该资源配置信息中携带的索引，就可以获得该目标资源池的上述资源配置信息。Considering that multiple resource pools can be configured on each carrier, more conveniently, the resource pool configuration information of the target resource pool can also carry the index of the target resource pool. For example, a plurality of candidate resource pools may be preconfigured (for example, the resource configuration information of each candidate resource pool in the plurality of candidate resource pools is preconfigured), and each candidate resource pool has its own unique index. According to the first side row The resource configuration information of the target resource pool can be obtained by using the index carried in the resource configuration information carried on the transmission channel.
