本发明涉及通信技术领域，尤其涉及一种通信方法及上行资源确定方法。The present invention relates to the field of communication technologies, and in particular, to a communication method and a method for determining uplink resources.
背景技术Background technique
随着无线通信技术的发展以及业务量的增加，无线通信系统的频谱资源日益稀缺，这就要求无线通信系统需要提高频谱利用率，从而时分双工(time divisionduplexing，TDD)技术和载波聚合(carrier aggregation，CA)技术应运而生。With the development of wireless communication technology and the increase of business volume, the spectrum resources of wireless communication systems are becoming increasingly scarce, which requires the wireless communication system to improve spectrum utilization, so that time division duplexing (TDD) technology and carrier aggregation (carrier aggregation) need to be improved. aggregation, CA) technology came into being.
在TDD技术和CA技术中，存在终端设备需要在同一个上行控制信息(uplinkcontrol information，UCI)反馈网络设备发送的多个下行数据对应的多个ACK/NACK应答情况，如图1所示，为在TDD技术中的在同一UCI中反馈多个下行数据的ACK/NACK应答的一种示例，在图1中，网络设备通过在3个物理下行控制信道(physical downlink controlchannel，PDCCH)资源中发送的3个DCI，向终端设备指示了3个物理下行共享信道(physicaldownlink shared channel，PDSCH)资源，终端设备在接收到的该3个DCI后，则根据与网络设备预定好的目标DCI以及该目标DCI所占用的PDCCH资源，例如，基站发送的最后一个DCI以及该最后一个DCI所占用的PDCCH资源，确定网络设备为终端设备配置的用于发送UCI的物理上行控制信道(physical uplink control channel，PUCCH)资源。这样，当终端设备通过该3个PDSCH资源接收到下行数据后，则在该PUCCH资源上反馈该下行数据的接收情况。In TDD technology and CA technology, there is a situation where the terminal device needs to feed back multiple ACK/NACK responses corresponding to multiple downlink data sent by the network device in the same uplink control information (UCI), as shown in Figure 1, for An example of feeding back ACK/NACK responses of multiple downlink data in the same UCI in the TDD technology, in FIG. 1, the network device sends the 3 DCIs, indicating 3 physical downlink shared channel (PDSCH) resources to the terminal equipment. After the terminal equipment receives the 3 DCIs, the terminal equipment determines the target DCI and the target DCI according to the predetermined target DCI with the network equipment. The occupied PDCCH resources, for example, the last DCI sent by the base station and the PDCCH resources occupied by the last DCI, determine the physical uplink control channel (physical uplink control channel, PUCCH) configured by the network device for the terminal device for sending UCI resource. In this way, after the terminal device receives downlink data through the three PDSCH resources, it feeds back the reception situation of the downlink data on the PUCCH resource.
然而，在通信过程中，网络设备向终端设备发送的DCI可能存在丢失或者终端设备没有接收到的情况，例如，网络设备向终端设备发送了3个DCI，但是在传输过程中，第3个DCI丢失，则终端设备只接收到了第1个DCI和第2个DCI。由于终端设备并不知道第3个DCI丢失，因此，终端设备将根据接收到的最后一个DCI，即网络设备发送的第2个DCI，以及该DCI所占用的PDCCH资源来确定发送UCI的PUCCH资源。However, during the communication process, the DCI sent by the network device to the terminal device may be lost or not received by the terminal device. For example, the network device sends 3 DCIs to the terminal device, but during the transmission process, the third DCI If it is lost, the terminal device only receives the first DCI and the second DCI. Since the terminal device does not know that the third DCI is lost, the terminal device will determine the PUCCH resource for sending UCI according to the last received DCI, that is, the second DCI sent by the network device, and the PDCCH resource occupied by the DCI. .
由于终端设备接收到的最后一个DCI并不是网络设备发送的最后一个DCI，那么，终端设备接收到的最后一个DCI所占用的PDCCH资源也不是网络设备调度的最后一个PDCCH资源，则终端设备确定出的用于发送UCI的PUCCH资源便不是网络设备实际指示给终端设备用于发送UCI的PUCCH资源，从而造成PUCCH资源的确定错误，导致和其他终端设备使用的PUCCH资源冲突，网络设备可能接收不到终端设备反馈的ACK/NACK应答。Since the last DCI received by the terminal device is not the last DCI sent by the network device, then the PDCCH resource occupied by the last DCI received by the terminal device is not the last PDCCH resource scheduled by the network device, then the terminal device determines that The PUCCH resource used for sending UCI is not the PUCCH resource actually indicated by the network device to the terminal device for sending UCI, resulting in an error in the determination of the PUCCH resource, resulting in a conflict with the PUCCH resource used by other terminal devices, and the network device may not receive it. The ACK/NACK response fed back by the terminal device.

在现有技术中，请参考图3，终端设备根据网络设备发送的DCI以及该DCI所占用的PDCCH资源，确定用于发送UCI的PUCCH资源的步骤如下。本发明主要考虑终端设备接收多个DCI，并在同一上行PUCCH资源上反馈该多个DCI指示的下行数据的接收情况的情形。In the prior art, please refer to FIG. 3 , the terminal device determines the PUCCH resource for sending UCI according to the DCI sent by the network device and the PDCCH resource occupied by the DCI as follows. The present invention mainly considers a situation where a terminal device receives multiple DCIs and feeds back the reception conditions of downlink data indicated by the multiple DCIs on the same uplink PUCCH resource.
S301：网络设备向终端设备配置多个PUCCH资源集合。S301: The network device configures multiple PUCCH resource sets to the terminal device.
网络设备通过高层信令，例如RRC信令给终端设备配置多个PUCCH资源，通常为4-8个，例如，PUCCH资源1表示占用物理资源块1(Physical Resource Block，PRB)以及符号1并使用PUCCH format0传输UCI，PUCCH资源2表示占用PRB2以及符号2，符号3，符号4和符号5，并使用PUCCH format1传输UCI等。根据DCI中PUCCH资源指示(PUCCH resource indicator)字段包含的比特数(2比特)将该多个PUCCH资源分为4个PUCCH资源集合，以网络设备给终端设备配置了8个PUCCH资源为例，则每个PUCCH资源集合中包含有两个PUCCH资源，如图4所示。The network device configures multiple PUCCH resources for the terminal device through high-layer signaling, such as RRC signaling, usually 4-8. For example, PUCCH resource 1 indicates that physical resource block 1 (Physical Resource Block, PRB) and symbol 1 are occupied and used. PUCCH format0 transmits UCI, and PUCCH resource 2 indicates that PRB2 and symbol 2, symbol 3, symbol 4 and symbol 5 are occupied, and UCI is transmitted using PUCCH format 1, etc. According to the number of bits (2 bits) contained in the PUCCH resource indicator (PUCCH resource indicator) field in the DCI, the multiple PUCCH resources are divided into 4 PUCCH resource sets. Each PUCCH resource set includes two PUCCH resources, as shown in FIG. 4 .
S302：网络设备确定终端设备用于发送UCI的PUCCH资源。S302: The network device determines the PUCCH resource used by the terminal device to send the UCI.
网络设备从多个PUCCH资源中确定一个PUCCH资源，用于终端设备发送UCI的PUCCH资源。例如，网络设备确定PUCCH资源集合01中的第一个PUCCH资源为终端设备发送UCI的PUCCH资源。The network device determines one PUCCH resource from multiple PUCCH resources, which is used by the terminal device to send the UCI PUCCH resource. For example, the network device determines that the first PUCCH resource in the PUCCH resource set 01 is the PUCCH resource for the terminal device to send UCI.
S303：网络设备在多个PDCCH资源上向终端设备发送多个DCI。S303: The network device sends multiple DCIs to the terminal device on multiple PDCCH resources.
网络设备在多个PDCCH资源上向终端设备发送DCI，以通过DCI指示的PDSCH资源向终端设备发送下行数据，并通过DCI以及该最后一个DCI所占用的PDCCH资源向终端设备指示该用于发送UCI的PUCCH资源。该多个PDCCH资源中的每个PDCCH资源是由控制信道元素CCE组成的。如图5所示，假设整个无线通信系统的控制信道的带宽可以分为16个CCE，分别为CCE0-CCE15，假设网络设备调度3个PDCCH资源，则第一个PDCCH资源可以由CCE0和CCE1组成，第二个PDCCH资源可以由CCE2组成，第三个PDCCH资源可以由CCE3和CCE4组成，网络设备在该3个PDCCH资源上发送3个DCI。该3个DCI中的每个DCI除了包含指示的PDSCH资源的信息，还包含有上行控制信道资源指示信息(PUCCH resource indicator)，该指示信息包含2个比特，该指示信息用于向终端设备指示使用网络设备配置的4个PUCCH资源集合中的哪一个PUCCH资源集合，该指示信息的值对应PUCCH资源集合的序号，例如，该指示信息为01，则指示使用PUCCH资源集合01。终端设备根据最后一个DCI所占用的PDCCH资源确定用于发送UCI的PUCCH资源的公式如下：The network equipment sends DCI to the terminal equipment on multiple PDCCH resources, so as to send downlink data to the terminal equipment through the PDSCH resources indicated by the DCI, and indicates to the terminal equipment that the UCI is used for sending UCI through the DCI and the PDCCH resources occupied by the last DCI. the PUCCH resource. Each PDCCH resource in the plurality of PDCCH resources is composed of a control channel element CCE. As shown in Figure 5, it is assumed that the bandwidth of the control channel of the entire wireless communication system can be divided into 16 CCEs, which are CCE0-CCE15 respectively. Assuming that the network device schedules 3 PDCCH resources, the first PDCCH resource can be composed of CCE0 and CCE1 , the second PDCCH resource may be composed of CCE2, the third PDCCH resource may be composed of CCE3 and CCE4, and the network device sends three DCIs on the three PDCCH resources. Each of the 3 DCIs includes, in addition to the indicated PDSCH resource information, also includes uplink control channel resource indication information (PUCCH resource indicator), the indication information includes 2 bits, and the indication information is used to indicate to the terminal equipment Which PUCCH resource set among the four PUCCH resource sets configured by the network device is used, the value of the indication information corresponds to the serial number of the PUCCH resource set, for example, if the indication information is 01, it indicates that the PUCCH resource set 01 is used. The formula for the terminal equipment to determine the PUCCH resource for sending UCI according to the PDCCH resource occupied by the last DCI is as follows:
其中，r为用于发送UCI的PUCCH资源在PUCCH资源集合01中的序号，由于每个PUCCH资源集合中包含1个或者2个PUCCH资源，例如，网络设备给终端设备配置了8个PUCCH资源，则每个PUCCH资源集合中有2个PUCCH资源；网络设备给终端设备配置了少于8个PUCCH资源，则有些PUCCH资源集合中则只包含1个PUCCH资源，因此，该序号的取值为0，或者1；M为PUCCH资源集合中包含的PUCCH资源个数，为1或者2，L为最后一个DCI所占用的PDCCH的聚合级别，可以为1,2,4,8,16，C为最后一个DCI所占用的PDCCH资源的起始CCE序号。若网络设备调度3个PDCCH资源，则最后一个DCI所占用的PDCCH资源为第三个PDCCH资源，为了使终端设备能够确定出使用PUCCH资源集合01中的第一个PUCCH资源，则网络设备要控制第三个PDCCH资源的起始CCE与该PDCCH的聚合级别的比值与M进行取模运算后的值为0，因此，若网络设备控制第三个PDCCH资源的聚合级别为2，则第三个PDCCH资源的起始CCE的序号可以为0、4、8、12中的任意一个，则网络设备在调度第三个PDCCH资源时，则该第三个PDCCH资源必须为CCE0-CCE1、CCE4-CCE5、CCE8-CCE9以及CCE12-CCE13中的一个，网络设备可以根据实际情况选择其中一个，例如，确定第三个PDCCH资源为CCE0-CCE1。而对第一个PDCCH资源和第二个PDCCH资源的起始CCE序号和聚合级别没有限制，网络设备可以任意配置，然后网络设备则在这3个PDCCH资源上发送3个DCI。Among them, r is the sequence number of the PUCCH resource used for sending UCI in the PUCCH resource set 01. Since each PUCCH resource set contains 1 or 2 PUCCH resources, for example, the network device configures 8 PUCCH resources for the terminal device, Then there are 2 PUCCH resources in each PUCCH resource set; the network device configures less than 8 PUCCH resources for the terminal device, and some PUCCH resource sets only contain 1 PUCCH resource, therefore, the value of the sequence number is 0 , or 1; M is the number of PUCCH resources included in the PUCCH resource set, which is 1 or 2, L is the aggregation level of the PDCCH occupied by the last DCI, which can be 1, 2, 4, 8, 16, and C is the last The starting CCE sequence number of the PDCCH resource occupied by a DCI. If the network device schedules three PDCCH resources, the PDCCH resource occupied by the last DCI is the third PDCCH resource. In order for the terminal device to determine to use the first PUCCH resource in the PUCCH resource set 01, the network device must control the The ratio of the starting CCE of the third PDCCH resource to the aggregation level of the PDCCH is 0 after modulo operation with M. Therefore, if the network device controls the aggregation level of the third PDCCH resource to be 2, then the third The sequence number of the starting CCE of the PDCCH resource can be any one of 0, 4, 8, and 12. When the network device schedules the third PDCCH resource, the third PDCCH resource must be CCE0-CCE1, CCE4-CCE5 , one of CCE8-CCE9 and CCE12-CCE13, the network device may select one of them according to the actual situation, for example, determine the third PDCCH resource as CCE0-CCE1. However, there is no restriction on the initial CCE sequence number and aggregation level of the first PDCCH resource and the second PDCCH resource, the network device can configure it arbitrarily, and then the network device sends three DCIs on the three PDCCH resources.
S304：终端设备在多个PDCCH资源上接收到多个DCI。S304: The terminal device receives multiple DCIs on multiple PDCCH resources.
终端设备在接收到该DCI信息后，根据接收到的DCI以及最后一个DCI占用的PDCCH资源的起始CCE序号以及该PDCCH资源的聚合级别来确定用于发送UCI的PUCCH资源。具体确定方式如公式(1)所示，在此不再赘述。After receiving the DCI information, the terminal device determines the PUCCH resource for sending UCI according to the received DCI, the starting CCE sequence number of the PDCCH resource occupied by the last DCI, and the aggregation level of the PDCCH resource. The specific determination method is shown in formula (1), which is not repeated here.
然而，由于在传输过程中存在丢失的情况，导致终端设备接收到的最后一个DCI并不是网络设备发送的最后一个DCI，那么，终端设备接收到的最后一个DCI所占用的PDCCH资源也不是网络设备调度的最后一个PDCCH资源，则终端设备确定出的用于发送UCI的PUCCH资源便不是网络设备实际指示给终端设备用于发送UCI的PUCCH资源，从而造成PUCCH资源的确定错误，与其他终端设备发送UCI的上行资源发生冲突，并导致网络设备可能接收不到终端设备反馈的ACK/NACK应答或者接收到错误的ACK/NACK应答。However, due to the loss in the transmission process, the last DCI received by the terminal device is not the last DCI sent by the network device, so the PDCCH resources occupied by the last DCI received by the terminal device are not the network device. The last PDCCH resource scheduled, the PUCCH resource determined by the terminal device for sending UCI is not the PUCCH resource actually indicated by the network device to the terminal device for sending UCI, resulting in an error in the determination of the PUCCH resource and sending it with other terminal devices. The uplink resources of the UCI collide, and the network device may not receive the ACK/NACK response fed back by the terminal device or receive an erroneous ACK/NACK response.
鉴于此，本申请实施例提供一种上行资源的确定方法，该方法包括：网络设备在N个下行资源上向终端设备发送下行信息；其中，该N个下行资源包含至少两个能够确定终端设备用于发送上行控制信息UCI的上行资源的第一下行资源，该至少两个第一下行资源都用于确定该上行资源，或者该至少两个第一下行资源中的一个资源用于确定该上行资源，该下行资源为下行控制信道资源和/或下行共享信道资源；若至少两个第一下行资源为网络设备发送的第一个下行信息所占的下行资源以及网络设备发送的最后一个下行信息所占用的下行资源，则该终端设备在接收该网络设备发送的K个下行信息时，若该K个下行信息中包含由该网络设备发送的第一个下行信息，该终端设备则根据该第一个下行信息所占用的下行资源确定用于发送上行控制信息UCI的上行资源，否则，该终端设备则根据该K个下行信息中最后接收到的下行信息所占用的下行资源确定用于发送所述UCI的上行资源；若至少两个第一下行资源为网络设备发送的第一个下行信息所占的下行资源以及网络设备发送的第二个下行信息所占用的下行资源，则该终端设备在接收该网络设备发送的K个下行信息时，若该K个下行信息中包含由该网络设备发送的第一个下行信息，该终端设备则根据该第一个下行信息所占用的下行资源确定用于发送上行控制信息UCI的上行资源，否则，该终端设备根据该K个下行信息中接收到的由该网络设备发送的第二个下行信息所占用的下行资源确定用于发送UCI的上行资源，该终端设备在确定用于发送UCI的上行资源后，则在该上行资源上发送UCI，从而该网络设备则在该上行资源上接收该终端设备发送的UCI。In view of this, an embodiment of the present application provides a method for determining uplink resources. The method includes: a network device sends downlink information to a terminal device on N downlink resources; wherein the N downlink resources include at least two that can determine the terminal device. The first downlink resource of the uplink resource used to send the uplink control information UCI, both of the at least two first downlink resources are used to determine the uplink resource, or one resource of the at least two first downlink resources is used to determine the uplink resource Determine the uplink resources, and the downlink resources are downlink control channel resources and/or downlink shared channel resources; if the at least two first downlink resources are the downlink resources occupied by the first downlink information sent by the network device and the downlink resources sent by the network device The downlink resources occupied by the last downlink information, when the terminal equipment receives K pieces of downlink information sent by the network equipment, if the K pieces of downlink information include the first downlink information sent by the network equipment, the terminal equipment Then determine the uplink resource for sending the uplink control information UCI according to the downlink resource occupied by the first downlink information, otherwise, the terminal device determines the downlink resource occupied by the last received downlink information in the K pieces of downlink information Uplink resources used for sending the UCI; if the at least two first downlink resources are the downlink resources occupied by the first downlink information sent by the network device and the downlink resources occupied by the second downlink information sent by the network device, Then, when the terminal device receives the K pieces of downlink information sent by the network device, if the K pieces of downlink information include the first downlink information sent by the network device, the terminal device will occupy the information according to the first downlink information. determine the uplink resource used for sending the uplink control information UCI, otherwise, the terminal device determines the downlink resource used for sending the second downlink information received from the K pieces of downlink information and occupied by the second downlink information sent by the network device. The uplink resource of the UCI, after the terminal device determines the uplink resource for sending the UCI, it sends the UCI on the uplink resource, so that the network device receives the UCI sent by the terminal device on the uplink resource.
在上述技术方案中，网络设备首先使用了至少两个第一下行资源来隐示指示终端设备用于发送UCI的上行资源，这样，当终端设备接收到该至少两个第一下行资源上的下行信息中的任意一个时，则根据接收到的该下行信息占用的下行资源确定用于发送UCI的上行资源，由于至少两个第一下行资源同时丢失的概率较低，因此，可以提高终端设备确定用于发送UCI的上行资源的正确率，不会与其他终端设备发送UCI的上行资源发生冲突，进一步可以提高ACK/NACK应答的传输可靠性。In the above technical solution, the network device firstly uses at least two first downlink resources to implicitly instruct the terminal device to use uplink resources for sending UCI, so that when the terminal device receives the at least two first downlink resources When any one of the downlink information received, the uplink resource used for sending UCI is determined according to the downlink resource occupied by the received downlink information. Since the probability of at least two first downlink resources being lost at the same time is low, it can be improved. The terminal device determines the correct rate of the uplink resources used for sending UCI, and will not conflict with the uplink resources used by other terminal devices to send UCI, which can further improve the transmission reliability of the ACK/NACK response.
下面将结合说明书附图以及具体的实施方式对本申请实施例中的技术方案进行详细的说明。在下面的介绍过程中，以本申请实施例提供的技术方案应用于图2所示的应用场景，以终端设备为UE，且网络设备是基站为例。The technical solutions in the embodiments of the present application will be described in detail below with reference to the accompanying drawings and specific implementation manners. In the following introduction process, the technical solutions provided by the embodiments of the present application are applied to the application scenario shown in FIG. 2 , and the terminal device is a UE and the network device is a base station as an example.
请参见图6，本申请实施例提供一种通信方法及上行资源的确定方法，该方法的流程描述如下：Referring to FIG. 6 , an embodiment of the present application provides a communication method and a method for determining uplink resources. The process of the method is described as follows:
S601：基站在N个下行资源上向所述终端设备发送下行信息。S601: The base station sends downlink information to the terminal device on the N downlink resources.
在本申请实施例中，下行资源可以是PDCCH资源和/或PDSCH资源，相应地，下行信息可以是DCI和/或下行数据，即基站可以在PDCCH资源上向UE发送DCI，也可以在PDSCH资源上向UE发送下行数据，也可以是基站先通过PDCCH资源向UE发送DCI，并通过PDSCH资源向UE发送下行数据，或者基站在不同的频域位置上同时调度PDCCH资源向UE发送DCI以及调度PDSCH资源向UE发送下行数据。当然，下行资源也可以是MPDCCH资源等，在本申请实施例中以下行资源为PDCCH资源和PDSCH资源为例进行说明。In this embodiment of the present application, the downlink resources may be PDCCH resources and/or PDSCH resources, and correspondingly, the downlink information may be DCI and/or downlink data, that is, the base station may send DCI to the UE on the PDCCH resources, or may use the PDSCH resources to send DCI to the UE. The uplink sends downlink data to the UE, or the base station first sends DCI to the UE through PDCCH resources, and then sends downlink data to the UE through PDSCH resources, or the base station simultaneously schedules PDCCH resources in different frequency domain locations to send DCI to the UE and schedule PDSCH. The resource sends downlink data to the UE. Of course, the downlink resources may also be MPDCCH resources, etc. In this embodiment of the present application, the downlink resources are PDCCH resources and PDSCH resources as an example for description.
基站通过调度PDCCH资源和PDSCH资源与UE进行通信。例如，可以采用时分双工(time division duplexing，TDD)方式或载波聚合(carrier aggregation，CA)方式与UE进行通信。下面将以基站调度PDCCH资源与UE通信为例，对这两种工作方式进行说明：The base station communicates with the UE by scheduling PDCCH resources and PDSCH resources. For example, a time division duplexing (time division duplexing, TDD) manner or a carrier aggregation (carrier aggregation, CA) manner may be used to communicate with the UE. The following will take the base station scheduling PDCCH resources to communicate with the UE as an example to describe these two working modes:
1)TDD方式：1) TDD method:
基站可以在不同的时域位置上调度多个位于不同或相同的频域位置的PDCCH资源，向UE发送DCI信息。如图5所示，基站调度了3个PDCCH资源，其中，PDCCH资源1对应时隙(slot)1及频率1，PDCCH资源2对应slot2及频率2，PDCCH资源3对应slot3及频率3。The base station may schedule multiple PDCCH resources located at different or the same frequency domain location at different time domain locations, and send DCI information to the UE. As shown in FIG. 5 , the base station schedules three PDCCH resources, wherein PDCCH resource 1 corresponds to slot 1 and frequency 1, PDCCH resource 2 corresponds to slot 2 and frequency 2, and PDCCH resource 3 corresponds to slot 3 and frequency 3.
2)CA方式：2) CA method:
基站可以在同一个时域位置上调度多个位于不同载波上的PDCCH资源，向UE发送DCI信息。如图7所示，基站调度了3个PDCCH资源，其中，PDCCH资源1位于载波1上，且占用的载波1的PDCCH资源为CCE0-CCE1，PDCCH资源2位于载波2上，且占用的载波2的PDCCH资源为CCE4-CCE6，PDCCH资源3对应载波3上，且占用的载波3的PDCCH资源为CCE9。需要说明的是，各个载波上的CCE的编号可以是相互独立的，即载波1对应由9个CCE，PDCCH资源1的CCE序号为在载波1的9个CCE中的序号，PDCCH资源2的CCE序号为在载波2的多个CCE中的序号。The base station may schedule multiple PDCCH resources located on different carriers at the same time domain location, and send DCI information to the UE. As shown in Figure 7, the base station schedules 3 PDCCH resources, among which, PDCCH resource 1 is located on carrier 1, and the occupied PDCCH resources of carrier 1 are CCE0-CCE1, and PDCCH resource 2 is located on carrier 2, and occupied carrier 2 The PDCCH resources are CCE4-CCE6, PDCCH resource 3 corresponds to carrier 3, and the occupied PDCCH resource of carrier 3 is CCE9. It should be noted that the numbers of CCEs on each carrier can be independent of each other, that is, carrier 1 corresponds to 9 CCEs, the CCE sequence number of PDCCH resource 1 is the sequence number of the 9 CCEs of carrier 1, and the CCE of PDCCH resource 2 The sequence number is the sequence number in the multiple CCEs of carrier 2 .
当基站在多个PDCCH资源向UE发送多个DCI，并在DCI指示的PDSCH资源上向UE发送下行数据，该PDSCH资源的位置与图5、图7类似，在此不再赘述。When the base station sends multiple DCIs to the UE on multiple PDCCH resources, and sends downlink data to the UE on the PDSCH resources indicated by the DCI, the positions of the PDSCH resources are similar to those in FIG. 5 and FIG. 7 , and are not repeated here.
在本申请实施例中，基站还需要根据指示给UE用于发送UCI的资源确定多个PDCCH资源，和/或根据指示给UE用于发送UCI的资源确定多个PDSCH资源。例如，在多个PDCCH资源中，存在至少两个第一PDCCH资源，该至少两个第一PDCCH资源用于向UE隐示指示用于发送UCI的上行资源，通过该至少两个第一PDCCH中的每一个PDCCH的频域资源，确定的UE用于发送UCI的PUCCH资源相同，则基站需要根据指示的UE发送UCI的资源确定该至少两个第一PDCCH资源，除该至少两个第一PDCCH资源外的PDCCH资源，基站可以直接根据下行资源的实际使用情况确定。In this embodiment of the present application, the base station also needs to determine multiple PDCCH resources according to the resources indicated to the UE for sending UCI, and/or determine multiple PDSCH resources according to the resources indicated to the UE for sending UCI. For example, among the multiple PDCCH resources, there are at least two first PDCCH resources, and the at least two first PDCCH resources are used to implicitly indicate to the UE uplink resources used for sending UCI, through the at least two first PDCCH resources The frequency domain resources of each PDCCH are the same as the determined PUCCH resources used by the UE to send UCI, then the base station needs to determine the at least two first PDCCH resources according to the indicated resources for the UE to send UCI, except for the at least two first PDCCH resources For PDCCH resources other than resources, the base station can directly determine the actual usage of downlink resources.
需要说明的是，基站或UE可以使用该至少两个第一PDCCH资源中的任意一个确定UE发送UCI的上行资源，也可以根据该至少两个第一PDCCH资源一起确定UE发送UCI的上行资源，在本申请中不作限制。另外，至少两个第一PDCCH资源的名称只是为了方便与N个PDCCH中的其他不用于确定该PUCCH资源的PDCCH进行区别，而使用的一个称呼，该至少两个第一PDCCH资源也可以使用别的名称，在此不作限制。It should be noted that the base station or the UE can use any one of the at least two first PDCCH resources to determine the uplink resources for the UE to send UCI, or can also determine the uplink resources for the UE to send UCI according to the at least two first PDCCH resources, No limitation is made in this application. In addition, the names of the at least two first PDCCH resources are only used to distinguish them from other PDCCHs in the N PDCCHs that are not used to determine the PUCCH resources, but are used as names. The at least two first PDCCH resources may also use other names. name, which is not limited here.
在一种可能的实现方式中，当下行资源为PDCCH资源时，该至少两个第一PDCCH资源包括：该N个PDCCH资源中的第一个PDCCH资源及该N个PDCCH资源中的最后一个PDCCH资源；或该N个PDCCH资源中的第一个PDCCH资源及该N个PDCCH资源中的第二个PDCCH资源；或该N个PDCCH资源中的最后两个PDCCH资源；或该N个PDCCH资源中的任意三个PDCCH资源；或该N个PDCCH资源中的任意i个PDCCH资源，i为大于等于2且小于等于N的整数。当下行资源为PDSCH资源时，该至少两个第一PDSCH资源与该至少两个第一PDCCH资源类似，在此不再赘述。In a possible implementation manner, when the downlink resources are PDCCH resources, the at least two first PDCCH resources include: the first PDCCH resource in the N PDCCH resources and the last PDCCH resource in the N PDCCH resources resource; or the first PDCCH resource among the N PDCCH resources and the second PDCCH resource among the N PDCCH resources; or the last two PDCCH resources among the N PDCCH resources; or among the N PDCCH resources or any i PDCCH resources in the N PDCCH resources, where i is an integer greater than or equal to 2 and less than or equal to N. When the downlink resources are PDSCH resources, the at least two first PDSCH resources are similar to the at least two first PDCCH resources, and details are not repeated here.
需要说明的是，该至少两个第一PDCCH资源或该至少两个第一PDSCH资源可以是基站预先与UE约定好的，或者标准规定的，或者静态/半静态配置的，也可以是基站在确定该至少两个第一PDCCH资源或该至少两个第一PDSCH资源后，通过指示信息指示给UE的，在本申请实施例中不作限制。It should be noted that the at least two first PDCCH resources or the at least two first PDSCH resources may be pre-agreed by the base station with the UE, or specified by the standard, or statically/semi-statically configured, or the base station may After the at least two first PDCCH resources or the at least two first PDSCH resources are determined, what is indicated to the UE through the indication information is not limited in this embodiment of the present application.
在一种可能实施方式中，上行资源可以为PUCCH资源。当然，若还可以通过其他上行资源承载UCI，则上行资源也可以是其他资源，在此不作限制。为方便说明，下面将上行资源以PUCCH资源为例进行说明。该PUCCH资源可以是基站预先为UE配置的，如图3中的S301所述，在此不再赘述。In a possible implementation, the uplink resources may be PUCCH resources. Of course, if the UCI can also be carried through other uplink resources, the uplink resources can also be other resources, which is not limited here. For convenience of description, the uplink resource is described below by taking the PUCCH resource as an example. The PUCCH resource may be pre-configured by the base station for the UE, as described in S301 in FIG. 3 , and details are not described herein again.
在本申请实施例中，当下行资源为PDCCH资源时，该PDCCH资源包括：PDCCH的频域资源、时域资源、码域资源以及端口号中的一种或多种，即基站可以通过PDCCH的频域资源、时域资源、码域资源以及端口号中的一种或多种，向UE隐示指示用于发送UCI的PUCCH资源的序号。具体的可以根据PDCCH的频域资源和/或时域资源的起始位置、结束位置或个数隐示指示用于发送UCI的PUCCH资源的序号。基站隐示指示用于发送UCI的PUCCH资源的序号的方式可以如图3中的S303中的公式(1)所示，其中，当基站通过PDCCH的任意一种资源确定用于发送UCI的PUCCH资源的序号时，公式(1)中的M的定义不变，为PDCCH资源中发送的DCI指示的PUCCH资源集合中包含的PUCCH资源的个数，而公式C和L的定义根据基站使用的PDCCH资源的不同而改变，公式(1)中也可以不使用参数L。例如，当基站可以通过PDCCH的频域资源隐示指示用于发送UCI的PUCCH资源的序号时，C为PDCCH的频域资源的起始CCE序号，或者结束CCE序号，或者CCE个数等，L为PDCCH的聚合级别，或者公式(1)中可以不使用参数L；当基站可以通过PDCCH的时域资源隐示指示用于发送UCI的PUCCH资源的序号时，C为PDCCH的时域资源的起始符号，或结束符号，或符号个数等，此时公式(1)中可以不使用参数L；当基站可以通过PDCCH的码域资源隐示指示用于发送UCI的PUCCH资源的序号时，C为PDCCH的码域资源的序列标识，此时公式(1)中可以不使用参数L；当基站通过PDCCH的端口号隐示指示用于发送UCI的PUCCH资源的序号时，计算公式可以变成：r＝Mod(Q,M)，其中，Q为PDCCH的端口号。当基站使用PDCCH的多种资源隐示指示用于发送UCI的PUCCH资源的序号时，例如，基站使用PDCCH的频域资源与端口号隐示指示用于发送UCI的PUCCH资源的序号，则计算公式可以为：r＝Mod((C/L)+Q,M)，当然，也可以采用其他计算公式，在此不作限制。In this embodiment of the present application, when the downlink resources are PDCCH resources, the PDCCH resources include: one or more of the frequency domain resources, time domain resources, code domain resources and port numbers of the PDCCH, that is, the base station can pass the PDCCH resources. One or more of frequency domain resources, time domain resources, code domain resources and port numbers, implicitly indicating to the UE the sequence number of the PUCCH resource used for sending UCI. Specifically, the sequence number of the PUCCH resource used for sending the UCI may be implicitly indicated according to the start position, end position or number of the frequency domain resources and/or time domain resources of the PDCCH. The manner in which the base station implicitly indicates the sequence number of the PUCCH resource used for sending UCI may be as shown in formula (1) in S303 in FIG. 3 . When the serial number is , the definition of M in formula (1) remains unchanged, which is the number of PUCCH resources included in the PUCCH resource set indicated by the DCI sent in the PDCCH resource, and the definitions of formulas C and L are based on the PDCCH resources used by the base station. The parameter L may not be used in formula (1). For example, when the base station can implicitly indicate the sequence number of the PUCCH resource used for sending UCI through the frequency domain resource of the PDCCH, C is the starting CCE sequence number of the frequency domain resource of the PDCCH, or the ending CCE sequence number, or the number of CCEs, etc., L is the aggregation level of PDCCH, or parameter L may not be used in formula (1); when the base station can implicitly indicate the sequence number of the PUCCH resource used to send UCI through the time domain resource of the PDCCH, C is the start of the time domain resource of the PDCCH. Start symbol, or end symbol, or the number of symbols, etc. In this case, the parameter L may not be used in formula (1); when the base station can implicitly indicate the sequence number of the PUCCH resource used for sending UCI through the code domain resource of the PDCCH, C is the sequence identifier of the code domain resource of the PDCCH, and the parameter L may not be used in formula (1) at this time; when the base station implicitly indicates the sequence number of the PUCCH resource used for sending UCI through the port number of the PDCCH, the calculation formula can become: r=Mod(Q, M), where Q is the port number of the PDCCH. When the base station uses multiple resources of PDCCH to implicitly indicate the sequence number of the PUCCH resource used for sending UCI, for example, the base station uses the frequency domain resource and port number of the PDCCH to implicitly indicate the sequence number of the PUCCH resource used for sending UCI, then the calculation formula It can be: r=Mod((C/L)+Q, M). Of course, other calculation formulas can also be used, which is not limited here.
当下行资源为PDSCH资源时，该PDSCH资源包括：PDSCH的频域资源、时域资源、码域资源以及端口号中的一种或多种。具体隐示指示的方法与PDCCH资源相同，在此不再赘述。When the downlink resources are PDSCH resources, the PDSCH resources include: one or more of PDSCH frequency domain resources, time domain resources, code domain resources and port numbers. The specific implicit indication method is the same as that of the PDCCH resource, and will not be repeated here.
需要说明的是，基站使用的何种资源隐示指示PUCCH资源的序号以及每一种资源确定PUCCH资源的序号的计算公式可以是基站与UE预先预定好的，或者标准规定的，或者静态/半静态配置的，也可以是基站指示给UE的，在此不作限制。It should be noted that what kind of resource used by the base station implicitly indicates the sequence number of the PUCCH resource and the calculation formula for determining the sequence number of the PUCCH resource for each resource may be predetermined by the base station and the UE, or specified by the standard, or static/semi- The static configuration may also be indicated to the UE by the base station, which is not limited here.
基站确定至少两个PDCCH资源的方式有如下两种方式，基站可以采用任意一种：There are two ways for the base station to determine at least two PDCCH resources, and the base station can use any one of them:
第一种方式：The first way:
基站从多个PUCCH资源中确定一个PUCCH资源，为UE发送UCI的PUCCH资源。例如，确定PUCCH资源集合01中的第一个PUCCH资源为UE发送UCI的PUCCH资源。若基站通过PDCCH的频域资源隐示指示该PUCCH资源的在PUCCH资源集合01中的序号，则基站可以采用S303中的方法，确定出该至少两个PDCCH中每个PDCCH的频域资源起始CCE序号以及每个PDCCH的聚合级别，以使该至少两个PDCCH中的每一个PDCCH的频域资源确定的UE用于发送UCI的PUCCH资源相同。具体到计算公式，则有：The base station determines one PUCCH resource from multiple PUCCH resources, and sends the PUCCH resource of UCI to the UE. For example, it is determined that the first PUCCH resource in the PUCCH resource set 01 is the PUCCH resource for the UE to send UCI. If the base station implicitly indicates the sequence number of the PUCCH resource in the PUCCH resource set 01 through the frequency domain resource of the PDCCH, the base station can use the method in S303 to determine the start of the frequency domain resource of each PDCCH in the at least two PDCCHs The CCE sequence number and the aggregation level of each PDCCH are used to make the PUCCH resources used by the UE for sending UCI to be the same as determined by the frequency domain resources of each PDCCH in the at least two PDCCHs. Specific to the calculation formula, there are:
例如，该至少两个PDCCH资源为N个PDCCH资源中的第一个PDCCH资源及最后一个PDCCH资源，为了使第一个PDCCH和最后一个PDCCH的频域资源均隐示指示PUCCH资源集合01中的第一个PUCCH资源，则可以调控第一个PDCCH的频域资源为CCE0-CCE1(L＝2)，以及调控最后一个PDCCH的频域资源为CCE2(L＝1)。For example, the at least two PDCCH resources are the first PDCCH resource and the last PDCCH resource in the N PDCCH resources, so that the frequency domain resources of the first PDCCH and the last PDCCH all implicitly indicate the For the first PUCCH resource, the frequency domain resource of the first PDCCH can be regulated to be CCE0-CCE1 (L=2), and the frequency domain resource of the last PDCCH can be regulated to be CCE2 (L=1).
第二种方式：The second way:
基站不需要预先从多个PUCCH资源中确定UE发送UCI的PUCCH资源，而是通过至少两个PDCCH中的第一个PDCCH资源来确定该至少两个PDCCH中其他的的PDCCH的资源，以使该至少两个PDCCH中的每一个PDCCH的频域资源确定的UE用于发送UCI的PUCCH资源相同。例如，该至少两个PDCCH资源为N个PDCCH资源中的第一个PDCCH资源及最后一个PDCCH资源，基站通过PDCCH的频域资源隐示指示该PUCCH资源的在PUCCH资源集合01中的序号，则基站可以按照正常的调度算法确定第一个PDCCH的频域资源，例如，第一个PDCCH的频域资源为CCE2-CCE3(L＝2)，然后，基站根据第一个PDCCH的频域资源确定出其隐示指示的PUCCH资源的序号为1，则基站确定最后一个PDCCH的频域资源隐示指示的PUCCH资源的序号为1，基站可以确定最后一个PDCCH的频域资源为CCE4-CCE7(L＝4)。The base station does not need to determine the PUCCH resource for the UE to send the UCI from the multiple PUCCH resources in advance, but determines the other PDCCH resources in the at least two PDCCHs by using the first PDCCH resource in the at least two PDCCHs, so that the The PUCCH resources used by the UE to transmit the UCI are the same as determined by the frequency domain resources of each of the at least two PDCCHs. For example, the at least two PDCCH resources are the first PDCCH resource and the last PDCCH resource in the N PDCCH resources, and the base station indicates the sequence number of the PUCCH resource in the PUCCH resource set 01 through the frequency domain resource of the PDCCH implicitly, then The base station can determine the frequency domain resources of the first PDCCH according to the normal scheduling algorithm. For example, the frequency domain resources of the first PDCCH are CCE2-CCE3 (L=2), and then the base station determines according to the frequency domain resources of the first PDCCH. The sequence number of the PUCCH resource indicated by its implicit indication is 1, then the base station determines that the sequence number of the PUCCH resource implicitly indicated by the frequency domain resource of the last PDCCH is 1, and the base station can determine that the frequency domain resource of the last PDCCH is CCE4-CCE7 (L = 4).
基站确定至少两个PDSCH资源的方式与确定至少两个PDCCH资源的方式相同，在此不再赘述。The manner in which the base station determines the at least two PDSCH resources is the same as the manner in which the at least two PDCCH resources are determined, and details are not described herein again.
当基站确定N个PDCCH资源或N个PDSCH资源后，则在对应的资源上向UE发送相应的信息。具体来讲，基站向UE发送相应的信息的方式可以是如下两种情况中的一种。以基站通过N个PDCCH资源向UE发送DCI为例，基站可以是确定一个PDCCH资源后，在在该PDCCH资源上发送DCI，然后在确定下一个PDCCH资源；或者，基站也可以是先确定N个PDCCH资源中的每个PDCCH资源后，然后在依次在该N个PDCCH资源上发送DCI，在此不作限制。After the base station determines N PDCCH resources or N PDSCH resources, it sends corresponding information to the UE on the corresponding resources. Specifically, the manner in which the base station sends the corresponding information to the UE may be one of the following two cases. Taking the base station sending DCI to the UE through N PDCCH resources as an example, the base station may determine a PDCCH resource, send DCI on the PDCCH resource, and then determine the next PDCCH resource; or, the base station may first determine N PDCCH resources. After each PDCCH resource in the PDCCH resources, DCI is then sent on the N PDCCH resources in sequence, which is not limited here.
需要说明的是，当下行资源为PDSCH资源时，基站的处理方式的原理与下行资源为PDCCH资源时相同，因此，在本申请实施例中不再对下行资源为PDSCH资源的情况进行单独描述。It should be noted that when the downlink resources are PDSCH resources, the principle of the processing method of the base station is the same as when the downlink resources are PDCCH resources. Therefore, the case where the downlink resources are PDSCH resources is not described separately in this embodiment of the present application.
S602：UE接收基站发送的K个下行信息。S602: The UE receives K pieces of downlink information sent by the base station.
为方便描述，下面以下行资源为PDCCH资源、下行信息为DCI为例进行说明。For the convenience of description, the following description is given as an example that the downlink resources are PDCCH resources and the downlink information is DCI.
UE通过盲检的方式，在公共搜索空间(Common Search Space，CSS)和特定搜索空间(Specific Search Space，SSS)中进行搜索，从而获取基站发送的DCI。The UE searches in a common search space (Common Search Space, CSS) and a specific search space (Specific Search Space, SSS) by means of blind detection, so as to obtain the DCI sent by the base station.
需要说明的是，虽然基站向UE发送了N个DCI，但是UE可能没有全部接收，例如，UE只接收到N-1个DCI，因此，K小于等于N，并且K大于等于零的正整数It should be noted that although the base station sends N DCIs to the UE, the UE may not receive all of them. For example, the UE only receives N-1 DCIs. Therefore, K is less than or equal to N, and K is a positive integer greater than or equal to zero
当UE接收到基站发送的DCI后，则通过承载DCI的至少两个PDCCH资源中的一个，确定用于发送UCI的PUCCH资源。根据至少两个PDCCH资源是N个PDCCH资源中具体哪个资源，UE确定用于发送UCI的PUCCH资源的方式不同，主要分为如下四种方式。After receiving the DCI sent by the base station, the UE determines the PUCCH resource for sending the UCI by using one of the at least two PDCCH resources carrying the DCI. Depending on which of the N PDCCH resources the at least two PDCCH resources are, the manner in which the UE determines the PUCCH resource for sending the UCI is different, and is mainly divided into the following four manners.
第一种确定方式，至少两个第一下行资源为该N个PDCCH资源中的第一个PDCCH资源及该N个PDCCH资源中的最后一个PDCCH资源；或至少两个第一下行资源为该N个PDCCH资源中的第一个PDCCH资源、倒数第二个PDCCH资源以及最后一个PDCCH资源：In the first determination method, the at least two first downlink resources are the first PDCCH resource in the N PDCCH resources and the last PDCCH resource in the N PDCCH resources; or the at least two first downlink resources are The first PDCCH resource, the penultimate PDCCH resource and the last PDCCH resource among the N PDCCH resources:
S603：若K个下行信息中包含基站发送的第一个下行信息，UE根据该第一个下行信息所占用的下行资源确定用于发送UCI的PUCCH资源。S603: If the K pieces of downlink information include the first downlink information sent by the base station, the UE determines a PUCCH resource for sending UCI according to the downlink resources occupied by the first downlink information.
当UE接收到K个DCI后，则根据DCI中携带的counter下行链路任务索引(downlinkassignment index，DAI)和/或total DAI确定出是否接收到基站发送的第一个DCI。以下以counter DAI为例说明。具体来讲，当UE接收到第一个DCI时，获取该DCI中的counter DAI的取值，当该取值为1时，则表示该DCI为基站发送的第一个DCI，然后，UE则接收到的第一个DCI中包含的PUCCH resource indicator的取值确定用于发送UCI的PUCCH资源所在的PUCCH资源集合，然后根据接收到的第一个DCI所占用的PDCCH资源确定用于发送UCI的PUCCH资源在该PUCCH资源集合中的序号。由于PDCCH资源包含PDCCH的频域资源、时域资源、码域资源以及端口号中的任意一种或多种，而基站会根据预先约定好的资源进行隐示指示或者基站会向UE指示使用了何种资源进行隐示指示，因此，UE在获取对应的PDCCH资源后，则根据S601中记载的方法确定出PUCCH资源的序号，在此不再赘述。After the UE receives K pieces of DCI, it determines whether the first DCI sent by the base station is received according to the counter downlink assignment index (downlink assignment index, DAI) and/or total DAI carried in the DCI. The following uses counter DAI as an example. Specifically, when the UE receives the first DCI, it obtains the value of the counter DAI in the DCI. When the value is 1, it means that the DCI is the first DCI sent by the base station. The value of the PUCCH resource indicator included in the received first DCI determines the PUCCH resource set where the PUCCH resources used for sending UCI are located, and then determines the PUCCH resource set used for sending UCI according to the PDCCH resources occupied by the first received DCI. The sequence number of the PUCCH resource in the PUCCH resource set. Since the PDCCH resources include any one or more of the frequency domain resources, time domain resources, code domain resources and port numbers of the PDCCH, the base station will implicitly indicate according to the pre-agreed resources, or the base station will indicate to the UE that it has been used. Which resource is implicitly indicated, therefore, after the UE obtains the corresponding PDCCH resource, it determines the sequence number of the PUCCH resource according to the method described in S601, which will not be repeated here.
S604：若K个下行信息中未包含基站发送的第一个下行信息，UE根据该K个下行信息中最后接收到的下行信息所占用的下行资源确定用于发送UCI的PUCCH资源。S604: If the K pieces of downlink information do not include the first downlink information sent by the base station, the UE determines a PUCCH resource for sending UCI according to downlink resources occupied by the last received downlink information in the K pieces of downlink information.
当UE接收到第一个DCI时，获取该DCI中的counter DAI的取值，当该取值不为1，例如为2，则表示UE接收到的第一个DCI为基站发送的第二个DCI。然后，UE则根据接收到的多个DCI中任意一个DCI以及最后一个DCI所占用的PDCCH资源确定用于发送UCI的PUCCH资源，具体的确定方法与S603中相同，在此不再赘述。When the UE receives the first DCI, it obtains the value of the counter DAI in the DCI. When the value is not 1, such as 2, it means that the first DCI received by the UE is the second one sent by the base station. DCI. Then, the UE determines the PUCCH resource for sending the UCI according to any one of the received multiple DCIs and the PDCCH resource occupied by the last DCI. The specific determination method is the same as that in S603, which is not repeated here.
需要说明的是，UE根据是否接收到基站发送的第一个DCI确定执行S603或S604，即S603和S604是选择一个进行执行的。在图6中，以S604为可选步骤为例。It should be noted that the UE determines to execute S603 or S604 according to whether the first DCI sent by the base station is received, that is, S603 and S604 are selected to execute. In FIG. 6 , S604 is taken as an optional step as an example.
若基站在根据指示给UE用于发送UCI的PUCCH资源确定多个PDCCH资源时，控制倒数第二个PDCCH中隐式指示的PUCCH资源，与该第一个PDCCH资源及最后一个PDCCH资源隐式指示的PUCCH资源不一样，则本申请实施例中的方法还包括：If the base station determines multiple PDCCH resources according to the PUCCH resource indicated to the UE for sending UCI, it controls the PUCCH resource implicitly indicated in the penultimate PDCCH, and the first PDCCH resource and the last PDCCH resource implicitly indicated different PUCCH resources, the method in this embodiment of the present application further includes:
S605：UE确定丢失基站发送的最后一个下行信息。S605: The UE determines that the last downlink information sent by the base station is lost.
在至少两个第一下行资源包含该N个PDCCH资源中的第一个PDCCH资源及该N个PDCCH资源中的最后一个PDCCH资源，且UE通过S603确定接收到基站发送的第一个DCI，则若UE根据第一个DCI确定的用于发送UCI的PUCCH资源与UE根据接收到的最后一个DCI确定的用于发送UCI的PUCCH资源不同，则UE确定丢失基站发送的最后一个DCI，由于UE丢失了最后一个DCI，自然也无法从基站指示的最后一个PDSCH资源中接收基站发送的最后一个下行数据，因此，当UE在发送UCI时，可以增加对该丢失的最后一个下行数据的NACK应答，这样，基站在接收该UCI时则可以不用盲解码便能够确定UE丢失了最后一个下行数据。When the at least two first downlink resources include the first PDCCH resource in the N PDCCH resources and the last PDCCH resource in the N PDCCH resources, and the UE determines through S603 that it has received the first DCI sent by the base station, Then, if the PUCCH resource for sending UCI determined by the UE according to the first DCI is different from the PUCCH resource for sending UCI determined by the UE according to the last DCI received, the UE determines that the last DCI sent by the base station is lost. If the last DCI is lost, it is naturally impossible to receive the last downlink data sent by the base station from the last PDSCH resource indicated by the base station. Therefore, when the UE is sending UCI, it can add a NACK response to the lost last downlink data, In this way, the base station can determine that the UE has lost the last downlink data without blind decoding when receiving the UCI.
需要说明的是，S605是可选的，即不是必须执行的，即，UE可以不确定是否丢失最后一个DCI，即UE如果丢失了最后一个DCI，但没有使用S605的方法确定，则UE在发送UCI时，就不能够发送对该丢失的最后一个下行数据的NACK应答，即UCI中缺少了针对最后一个下行数据的应答比特，UCI的比特数目比基站预期接收到的UCI的比特数目要少，因此基站需要在接收该UCI时需要进行一次盲解码才能够确定UE丢失了最后一个下行数据。It should be noted that S605 is optional, that is, it is not mandatory to perform, that is, the UE may not determine whether the last DCI is lost, that is, if the UE loses the last DCI, but does not use the method of S605 to determine, the UE is sending In UCI, the NACK response to the lost last downlink data cannot be sent, that is, the UCI lacks the response bit for the last downlink data, and the number of UCI bits is less than the number of UCI bits expected to be received by the base station. Therefore, the base station needs to perform a blind decoding when receiving the UCI to be able to determine that the UE has lost the last downlink data.
S606：UE在PUCCH资源上发送UCI。S606: The UE sends the UCI on the PUCCH resource.
当UE接收到K个DCI后，则根据K个DCI确定K个PDSCH资源，然后在该K个PDSCH资源上接收基站发送的下行数据，并根据接收到的下行数据生成与每个PDSCH资源对应的ACK/NACK应答。例如，UE可以在UCI中使用K个比特来携带与这K个PDSCH资源中的下行数据的ACK/NACK应答，其中，每一个比特表征对对应的下行数据的ACK/NACK应答，例如，第1个比特为对接收到的第一个DCI指示的PDSCH资源中的下行数据的ACK/NACK应答，第2个比特为对接收到的第二个DCI指示的PDSCH资源中的下行数据的ACK/NACK应答，以此类推。当然，这只是UE反馈ACK/NACK应答的一种示例，在本申请中不对UE如何反馈ACK/NACK应答进行限制。When the UE receives K DCIs, it determines K PDSCH resources according to the K DCIs, and then receives the downlink data sent by the base station on the K PDSCH resources, and generates a corresponding PDSCH resource according to the received downlink data. ACK/NACK response. For example, the UE may use K bits in the UCI to carry the ACK/NACK response to the downlink data in the K PDSCH resources, wherein each bit represents the ACK/NACK response to the corresponding downlink data, for example, the first bits are the ACK/NACK response to the downlink data in the PDSCH resource indicated by the first DCI received, and the second bit is the ACK/NACK response to the downlink data in the PDSCH resource indicated by the second DCI received answer, and so on. Of course, this is only an example for the UE to feed back the ACK/NACK response, and how the UE feeds back the ACK/NACK response is not limited in this application.
第二种确定方式，请参考图8，至少两个第一下行资源为该N个PDCCH资源中的第一个PDCCH资源及该N个PDCCH资源中的第二个PDCCH资源：The second determination method, please refer to FIG. 8, the at least two first downlink resources are the first PDCCH resource in the N PDCCH resources and the second PDCCH resource in the N PDCCH resources:
S607：若K个下行信息中包含基站发送的第一个下行信息，UE根据该第一个下行信息所占用的下行资源确定用于发送上行控制信息UCI的PUCCH资源。S607: If the K pieces of downlink information include the first downlink information sent by the base station, the UE determines a PUCCH resource for sending the uplink control information UCI according to the downlink resources occupied by the first downlink information.
S608：若K个下行信息中未包含基站发送的第一个下行信息，则UE根据该K个下行信息中接收到的由基站发送的第二个下行信息所占用的下行资源确定用于发送UCI的PUCCH资源。在图8中，S608为可选的。S608: If the K pieces of downlink information do not include the first downlink information sent by the base station, the UE determines, according to the K pieces of downlink information, the downlink resources occupied by the second downlink information sent by the base station to be used for sending UCI the PUCCH resource. In FIG. 8, S608 is optional.
当UE接收到第一个DCI中的counter DAI的取值，当该取值不为1，UE确定未接收到基站发送的第一个DCI，则UE确定该取值是否为2，若该取值为2，则表示该DCI为基站发送的第二个DCI，则UE根据该DCI以及该DCI所占用的PDCCH资源确定用于发送UCI的PUCCH资源，具体的确定方法与S603中相同，在此不再赘述。When the UE receives the value of counter DAI in the first DCI, when the value is not 1, and the UE determines that it has not received the first DCI sent by the base station, the UE determines whether the value is 2, and if the value is 2 If the value is 2, it means that the DCI is the second DCI sent by the base station, and the UE determines the PUCCH resource for sending the UCI according to the DCI and the PDCCH resources occupied by the DCI. The specific determination method is the same as that in S603, here No longer.
需要说明的是，UE根据是否接收到基站发送的第一个DCI确定执行S607或S608，即S607和S608是选择一个进行执行的。It should be noted that the UE determines to execute S607 or S608 according to whether the first DCI sent by the base station is received, that is, S607 and S608 are selected to execute.
S609：UE在PUCCH资源上发送UCI。S609: The UE sends the UCI on the PUCCH resource.
S609与S606相同，在此不再赘述。需要说明的是，UE可以根据DCI中的counter DAI确定当前接收到的DCI为基站发送的第几个DCI，则UE接收到的第一个DCI的counter DAI为3时，则UE确定未接收到基站发送的第一个DCI及第二个DCI，即UE未接收到基站通过该至少两个PDCCH中的任意一个PDCCH发送的DCI，则UE可以选择不发送UCI。S609 is the same as S606 and will not be repeated here. It should be noted that the UE can determine, according to the counter DAI in the DCI, that the currently received DCI is the number of DCIs sent by the base station, and when the counter DAI of the first DCI received by the UE is 3, the UE determines that the DCI has not been received. The first DCI and the second DCI sent by the base station, that is, the UE does not receive the DCI sent by the base station through any one of the at least two PDCCHs, the UE may choose not to send the UCI.
第三种确定方式，至少两个第一下行资源为该N个PDCCH资源中的最后两个PDCCH资源时，UE则直接根据接收到的K个DCI中的任意一个DCI以及接收到的最后一个DCI的所占用的PDCCH资源确定用于发送UCI的上行资源。In the third determination method, when the at least two first downlink resources are the last two PDCCH resources in the N PDCCH resources, the UE directly determines according to any one of the received K DCIs and the last received The occupied PDCCH resource of the DCI determines the uplink resource for transmitting the UCI.
在这种情况下，若基站在根据指示给UE用于发送UCI的PUCCH资源确定多个PDCCH资源时，控制倒数第三个PDCCH中隐式指示的PUCCH资源，与该最后两个PDCCH资源隐式指示的PUCCH资源不一样，则本申请实施例中的方法还包括：In this case, if the base station determines multiple PDCCH resources according to the PUCCH resources indicated to the UE for sending UCI, it controls the PUCCH resources implicitly indicated in the third-to-last PDCCH, which are implicitly associated with the last two PDCCH resources. If the indicated PUCCH resources are different, the method in this embodiment of the present application further includes:
若UE根据接收到的倒数第二个DCI确定的用于发送UCI的PUCCH资源与UE根据接收到的最后一个DCI确定的用于发送UCI的PUCCH资源不同，则UE确定丢失基站发送的最后一个DCI，因此，当UE在发送UCI时，可以增加对该丢失的最后一个下行数据的NACK应答，从而基站在接收该UCI时则可以不用盲解码便能够确定UE丢失了最后一个下行数据。If the PUCCH resource for sending UCI determined by the UE according to the penultimate DCI received is different from the PUCCH resource for sending UCI determined by the UE according to the last DCI received, the UE determines that the last DCI sent by the base station is lost. Therefore, when the UE sends UCI, it can add a NACK response to the lost last downlink data, so that the base station can determine that the UE has lost the last downlink data without blind decoding when receiving the UCI.
第四种方式，请参考图9，至少两个第一下行资源为该N个PDCCH资源中的第一个PDCCH资源、第二个PDCCH资源以及最后一个PDCCH资源：The fourth way, please refer to FIG. 9, the at least two first downlink resources are the first PDCCH resource, the second PDCCH resource and the last PDCCH resource among the N PDCCH resources:
S610：若K个下行信息中包含基站发送的第一个下行信息，UE根据该第一个下行信息所占用的下行资源确定用于发送上行控制信息UCI的PUCCH资源。S610: If the K pieces of downlink information include the first downlink information sent by the base station, the UE determines a PUCCH resource for sending the uplink control information UCI according to the downlink resources occupied by the first downlink information.
S611：若K个下行信息中未包含基站发送的第一个下行信息，则UE根据该K个下行信息中接收到的由基站发送的第二个下行信息所占用的下行资源确定用于发送UCI的PUCCH资源；S611: If the K pieces of downlink information do not include the first downlink information sent by the base station, the UE determines, according to the K pieces of downlink information, the downlink resources occupied by the second downlink information sent by the base station to be used for sending UCI the PUCCH resource;
S610-S611与S607-S608相同，在此不再赘述。S610-S611 are the same as S607-S608, and are not repeated here.
S612：若UE确定未接收到基站发送的第一个DCI及第二个DCI，则根据接收到的最后一个DCI所占用的下行资源确定用于发送UCI的PUCCH资源。S612: If the UE determines that the first DCI and the second DCI sent by the base station have not been received, the UE determines the PUCCH resource for sending the UCI according to the downlink resources occupied by the last received DCI.
当UE通过DCI中的counter DAI的取值，确定未接收到基站发送的第一个DCI以及第二DCI，则UE根据接收到的多个DCI中任意一个DCI以及最后一个DCI所占用的PDCCH资源确定用于发送UCI的PUCCH资源，具体的确定方法与S603中相同，在此不再赘述。When the UE determines that it has not received the first DCI and the second DCI sent by the base station through the value of the counter DAI in the DCI, the UE determines the PDCCH resources occupied by any one of the received DCIs and the last DCI according to the received DCI. The specific determination method for determining the PUCCH resource used for sending the UCI is the same as that in S603, which is not repeated here.
需要说明的是，若基站在根据指示给UE用于发送UCI的PUCCH资源确定多个PDCCH资源时，控制N个PDCCH中的每一个PDCCH资源隐式指示的PUCCH资源均相同，则UE可以根据接收到的任意一个DCI所占用的PDCCH资源确定用于发送UCI的PUCCH资源。It should be noted that, if the base station determines multiple PDCCH resources according to the PUCCH resources indicated to the UE for sending UCI, and controls the PUCCH resources implicitly indicated by each of the N PDCCH resources to be the same, the UE can The PDCCH resource occupied by any DCI obtained determines the PUCCH resource used for sending the UCI.
在上述技术方案中，网络设备首先使用了至少两个下行资源来隐示指示终端设备用于发送UCI的上行资源，这样，当终端设备接收到该至少两个下行资源上的下行信息中的任意一个时，则根据接收到的该下行信息占用的下行资源确定用于发送UCI的上行资源，由于至少两个下行资源同时丢失的概率较低，因此，可以提高终端设备确定用于发送UCI的上行资源的正确率，不会与其他终端设备发送UCI的上行资源发生冲突，进一步可以提高ACK/NACK应答的传输可靠性。In the above technical solution, the network device first uses at least two downlink resources to implicitly instruct the terminal device to use the uplink resources for sending UCI, so that when the terminal device receives any of the downlink information on the at least two downlink resources When one of the downlink resources is received, the uplink resources used for sending UCI are determined according to the downlink resources occupied by the received downlink information. Since the probability of at least two downlink resources being lost at the same time is low, the determination of the uplink resources for sending UCI by the terminal equipment can be improved. The correct rate of resources will not collide with the uplink resources used by other terminal devices to send UCI, which can further improve the transmission reliability of ACK/NACK responses.
