图1示出了适用于本申请实施例提供的反馈信息传输方法的通信系统100的示意图。如图所示，该通信系统100可以包括：一个或多个网络设备110，一个或多个终端设备120至150。其中，该终端设备120至150可以是移动的或固定的。网络设备110和终端设备120至150中的一个或多个均可以通过无线链路通信。每个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内的终端设备通信。例如，网络设备可以向终端设备发送配置信息，终端设备可以基于该配置信息向网络设备发送上行数据；又例如，网络设备可以向终端设备发送下行数据。可以理解的，本申请对网络设备和终端设备的数量不作限制。FIG. 1 shows a schematic diagram of a communication system 100 suitable for the feedback information transmission method provided by the embodiment of the present application. As shown in the figure, the communication system 100 may include: one or more network devices 110 and one or more terminal devices 120 to 150 . The terminal devices 120 to 150 may be mobile or fixed. Each of the network device 110 and one or more of the end devices 120 to 150 may communicate over a wireless link. Each network device can provide communication coverage for a specific geographic area and can communicate with terminal devices located within that coverage area. For example, the network device may send configuration information to the terminal device, and the terminal device may send uplink data to the network device based on the configuration information; for another example, the network device may send downlink data to the terminal device. It can be understood that this application does not limit the number of network devices and terminal devices.
处于无线资源控制空闲(RRC_IDLE)态的终端设备，接收网络设备通过广播发送的系统信息，完成接入后转为无线资源控制连接(RRC_CONNECTED)态。对于RRC连接态下的终端设备，网络设备可以通过组播或者单播的传输方式向终端设备下发数据业务。例如图1中所示的终端设备120，网络设备110为其分配小区无线网络临时标识(cell-radio network temporary identifier,C-RNTI),终端设备120根据C-RNTI加扰的下行控制信息(downlink control information,DCI)进行数据的接收，这种点对点的数据传输方式即为单播(unicast)。网络设备110为终端设备130至150分配相同的组无线网络临时标识 (group-radio network temporary identifier,G-RNTI)，则终端设备130至150可以根据G-RNTI加扰的DCI接收相同的数据，这种点对多点的数据传输方式即为组播(multicast)，也称多播。在一个时间单元内，一个终端设备可能既接收单播调度数据，也接收组播调度数据，本申请对此不作限定。The terminal equipment in the radio resource control idle (RRC_IDLE) state receives the system information sent by the network equipment through broadcast, and switches to the radio resource control connected (RRC_CONNECTED) state after completing the access. For a terminal device in the RRC connection state, the network device can deliver data services to the terminal device through multicast or unicast transmission. For example, for the terminal device 120 shown in FIG. 1 , the network device 110 allocates a cell-radio network temporary identifier (C-RNTI) to it, and the terminal device 120 scrambles the downlink control information (downlink) according to the C-RNTI. control information, DCI) to receive data, this point-to-point data transmission method is unicast (unicast). The network device 110 allocates the same group-radio network temporary identifier (G-RNTI) to the terminal devices 130 to 150, then the terminal devices 130 to 150 can receive the same data according to the DCI scrambled by the G-RNTI, This point-to-multipoint data transmission method is multicast (multicast), also known as multicast. Within a time unit, a terminal device may receive both unicast scheduling data and multicast scheduling data, which is not limited in this application.
通过在单播和组播传输中引入HARQ反馈机制，可以更好地保证传输的可靠性。以终端设备120为例，终端设备120接收网络设备发送的DCI。DCI中的时域资源分配(time domain resource assignment)比特域指示物理下行共享信道(physical downlink shared channel,PDSCH)的时域信息，包括起始符号、时域长度等。终端设备根据该时域资源分配比特域接收PDSCH数据。如果接收正确，则终端设备120在物理上行控制信道(physical uplink control channel,PUCCH)上反馈HARQ-ACK信息，如果接收不正确，则反馈HARQ-NACK信息。在反馈HARQ-ACK信息时，终端设备120根据DCI中的PDSCH到HARQ反馈的定时指示(PDSCH-to-HARQ feedback timing indicator)比特域确定在哪一个上行时隙中反馈该PDSCH的HARQ-ACK信息，并根据要反馈的比特数确定一个PUCCH资源集合，其中包含多个PUCCH资源，终端设备120根据PUCCH资源指示(PUCCH resource indicator)比特域在PUCCH资源集合中选择一个PUCCH资源进行HARQ-ACK信息的传输。By introducing HARQ feedback mechanism in unicast and multicast transmission, the reliability of transmission can be better guaranteed. Taking the terminal device 120 as an example, the terminal device 120 receives the DCI sent by the network device. The time domain resource assignment (time domain resource assignment) bit field in the DCI indicates the time domain information of the physical downlink shared channel (PDSCH), including the start symbol, time domain length, and the like. The terminal device receives PDSCH data according to the time domain resource allocation bit domain. If the reception is correct, the terminal device 120 feeds back HARQ-ACK information on a physical uplink control channel (PUCCH), and if the reception is incorrect, feeds back HARQ-NACK information. When feeding back the HARQ-ACK information, the terminal device 120 determines in which uplink time slot the HARQ-ACK information of the PDSCH is fed back according to the PDSCH-to-HARQ feedback timing indicator bit field in the DCI , and determine a PUCCH resource set according to the number of bits to be fed back, which includes multiple PUCCH resources, and the terminal device 120 selects a PUCCH resource in the PUCCH resource set according to the PUCCH resource indicator (PUCCH resource indicator) bit field to perform HARQ-ACK information. transmission.

Wherein, if the priority indication bit field is "1", it indicates that the downlink data and its corresponding HARQ-ACK information are of high priority, and if it is "0", it indicates that the downlink data and its corresponding HARQ-ACK information are of low priority . For example, when a terminal device receives unicast scheduling data with a high unicast priority, it feeds back HARQ-ACK information with a high unicast priority accordingly; when it receives unicast scheduling data with a low unicast priority, it feeds back correspondingly low unicast scheduling data. Priority HARQ-ACK information.

For example, if the priority of the first multicast HARQ-ACK information is higher than the priority of the second multicast HARQ-ACK information, correspondingly, the priority of the first multicast codebook is higher than the priority of the second multicast codebook priority.
应理解，第一组播码本包括至少一个第一组播HARQ-ACK信息，第二组播码本包括至少一个所述第二组播HARQ-ACK信息。第一组播码本和第二组播码本重叠，指第一组播码本和第二组播码本在同一个时间单元中反馈，或者，第一组播码本和第二组播码本重叠，指承载第一组播码本和承载第二组播码本的时域资源全部或部分重叠，例如，第一组播码本和第二组播码本在同一个时隙中占用的部分符号重叠。It should be understood that the first multicast codebook includes at least one first multicast HARQ-ACK information, and the second multicast codebook includes at least one second multicast HARQ-ACK information.

At the same time, by multiplexing different multicast codebooks, the integrity of the multicast HARQ-ACK information can be preserved as much as possible, and the transmission reliability can be further improved.
与S210中确定第一HARQ-ACK码本的方法类似地，在S220中，终端设备可以根据几种不同的方法确定第二HARQ-ACK码本，下面分别对几种确定第二HARQ-ACK码本的方法做进一步的说明。Similar to the method for determining the first HARQ-ACK codebook in S210, in S220, the terminal device may determine the second HARQ-ACK codebook according to several different methods, and the following will determine the second HARQ-ACK code for several methods respectively.

For example, if the priority of the first unicast data is higher, the corresponding first unicast priority is higher, and vice versa. Similarly, the second unicast priority may reflect the priority of the second unicast data. Furthermore, the priority of the unicast HARQ-ACK information corresponds to the priority of the unicast data.

具体地，如果第一单播码本和第二单播码本之间有重叠，终端设备将第一单播码本确定为第二HARQ-ACK码本，弃用第二单播码本。Specifically, if there is overlap between the first unicast codebook and the second unicast codebook, the terminal device determines the first unicast codebook as the second HARQ-ACK codebook, and discards the second unicast codebook.
应理解，第一单播码本的优先级对应于第一单播HARQ-ACK信息的优先级，第二单播码本的优先级对应于第二单播HARQ-ACK信息的优先级。例如，若第一单播HARQ-ACK信息的优先级高于第二单播HARQ-ACK信息的优先级，对应地，则第一单播码本的优先级高于第二单播码本的优先级。It should be understood that the priority of the first unicast codebook corresponds to the priority of the first unicast HARQ-ACK information, and the priority of the second unicast codebook corresponds to the priority of the second unicast HARQ-ACK information. For example, if the priority of the first unicast HARQ-ACK information is higher than the priority of the second unicast HARQ-ACK information, correspondingly, the priority of the first unicast codebook is higher than the priority of the second unicast codebook priority.
应理解，第一单播码本包括至少一个第一单播HARQ-ACK信息，第二单播码本包括至少一个所述第二单播HARQ-ACK信息。第一单播码本和第二单播码本重叠，指第一单播码本和第二单播码本在同一时间单元中反馈，或者，承载第一单播码本和承载第二单播码本的时域资源部分或全部重叠。例如，第一单播码本和第二单播码本在同一个时隙中占用的部分符号重叠。It should be understood that the first unicast codebook includes at least one first unicast HARQ-ACK information, and the second unicast codebook includes at least one second unicast HARQ-ACK information. The overlapping of the first unicast codebook and the second unicast codebook means that the first unicast codebook and the second unicast codebook are fed back in the same time unit, or the first unicast codebook and the second unicast codebook are fed back. Part or all of the time domain resources of the broadcast codebook overlap. For example, some symbols occupied by the first unicast codebook and the second unicast codebook in the same time slot overlap.
因此，本申请实施例的传输反馈信息的方法，通过分别处理不同单播优先级的单播HARQ-ACK信息，可以解决单播HARQ-ACK信息的冲突，保证终端设备能够正常反馈不同下行调度数据的单播HARQ-ACK信息，从而提高传输可靠性。Therefore, the method for transmitting feedback information in the embodiments of the present application can resolve the conflict of unicast HARQ-ACK information by separately processing unicast HARQ-ACK information of different unicast priorities, and ensure that the terminal equipment can normally feed back different downlink scheduling data unicast HARQ-ACK information, thereby improving transmission reliability.
在S220中，可选地，根据单播HARQ-ACK信息确定第二HARQ-ACK码本，包括：In S220, optionally, determining the second HARQ-ACK codebook according to the unicast HARQ-ACK information, including:
S411，根据第一单播HARQ-ACK信息确定所述第一HARQ-ACK码本，所述第一单播HARQ-ACK信息为具有第一单播优先级的单播HARQ-ACK信息。S411. Determine the first HARQ-ACK codebook according to first unicast HARQ-ACK information, where the first unicast HARQ-ACK information is unicast HARQ-ACK information with a first unicast priority.
因此，本申请实施例的传输反馈信息的方法，通过在不同的单播HARQ-ACK信息中，选择具有第一单播优先级的单播HARQ-ACK信息，将其确定为第二HARQ-ACK码本， 可以解决不同单播HARQ-ACK信息的冲突，使得终端设备能够正常反馈不同下行调度数据的单播HARQ-ACK信息，从而提高传输可靠性。Therefore, in the method for transmitting feedback information according to the embodiment of the present application, the unicast HARQ-ACK information with the first unicast priority is selected among different unicast HARQ-ACK information, and it is determined as the second HARQ-ACK The codebook can solve the conflict of different unicast HARQ-ACK information, so that the terminal device can normally feed back the unicast HARQ-ACK information of different downlink scheduling data, thereby improving transmission reliability.
在S220中，可选地，根据单播HARQ-ACK信息确定第二HARQ-ACK码本，包括：In S220, optionally, determining the second HARQ-ACK codebook according to the unicast HARQ-ACK information, including:
S412，根据第一单播HARQ-ACK信息确定第一单播码本，第一单播HARQ-ACK信息为第一单播优先级的单播HARQ-ACK信息。S412: Determine the first unicast codebook according to the first unicast HARQ-ACK information, where the first unicast HARQ-ACK information is the unicast HARQ-ACK information of the first unicast priority.
S422，根据第二单播HARQ-ACK信息确定第二单播码本，第二单播HARQ-ACK信息为第二单播优先级的单播HARQ-ACK信息。S422: Determine a second unicast codebook according to the second unicast HARQ-ACK information, where the second unicast HARQ-ACK information is the unicast HARQ-ACK information of the second unicast priority.
S432，确定第二HARQ-ACK码本，第二HARQ-ACK码本包括第一单播码本和所述第二单播码本。S432: Determine a second HARQ-ACK codebook, where the second HARQ-ACK codebook includes a first unicast codebook and the second unicast codebook.
具体地，如果第一单播码本和第二单播码本之间有重叠，终端设备复用第一单播码本和第二单播码本，得到第二HARQ-ACK码本。第一单播码本和第二单播码本重叠，指第一单播码本和第二单播码本在同一时间单元中反馈，或者，承载第一单播码本和承载第二单播码本的时域资源重叠。其中，经过一次复用得到第二HARQ-ACK码本后，若承载该第二HARQ-ACK码本的时域资源，与承载其他第一单播码本或者其他第二单播码本或者其他第二HARQ-ACK码本的时域资源之间有重叠，则继续复用，直至得到与其他第一单播码本或其他第二单播码本或其他第二HARQ-ACK码本不重叠的第二HARQ-ACK码本。Specifically, if there is overlap between the first unicast codebook and the second unicast codebook, the terminal device multiplexes the first unicast codebook and the second unicast codebook to obtain a second HARQ-ACK codebook. The overlapping of the first unicast codebook and the second unicast codebook means that the first unicast codebook and the second unicast codebook are fed back in the same time unit, or the first unicast codebook and the second unicast codebook are fed back. The time domain resources of the broadcast codebook overlap. Wherein, after the second HARQ-ACK codebook is obtained after one multiplexing, if the time domain resources of the second HARQ-ACK codebook are carried, it is different from carrying other first unicast codebooks or other second unicast codebooks or other If there is overlap between the time-domain resources of the second HARQ-ACK codebook, continue to multiplex until the other first unicast codebook or other second unicast codebook or other second HARQ-ACK codebook does not overlap the second HARQ-ACK codebook.
因此，本申请实施例的传输反馈信息的方法，通过分别处理不同单播优先级的单播HARQ-ACK信息，可以解决单播HARQ-ACK信息的冲突，保证终端设备能够正常反馈不同下行调度数据的单播HARQ-ACK信息。同时，通过复用不同的单播码本，能够尽可能地保留单播HARQ-ACK信息的完整性，进一步提升传输可靠性。Therefore, the method for transmitting feedback information in the embodiments of the present application can resolve the conflict of unicast HARQ-ACK information by separately processing unicast HARQ-ACK information of different unicast priorities, and ensure that the terminal equipment can normally feed back different downlink scheduling data unicast HARQ-ACK information. At the same time, by multiplexing different unicast codebooks, the integrity of the unicast HARQ-ACK information can be preserved as much as possible, and the transmission reliability can be further improved.
在S230中，终端设备可以根据几种不同的方法确定第三HARQ-ACK码本，下面分别对几种确定第三HARQ-ACK码本的方法做进一步的说明。In S230, the terminal device may determine the third HARQ-ACK codebook according to several different methods, and the several methods for determining the third HARQ-ACK codebook will be further described below.
在S230中，根据所述第一HARQ-ACK码本和所述第二HARQ-ACK码本，确定第三HARQ-ACK码本，包括：In S230, determining a third HARQ-ACK codebook according to the first HARQ-ACK codebook and the second HARQ-ACK codebook, including:
若第一HARQ-ACK码本的优先级和第二HARQ-ACK码本的优先级相同，则根据第一HARQ-ACK码本和第二HARQ-ACK码本确定第三HARQ-ACK码本；若第一HARQ-ACK码本的优先级和第二HARQ-ACK码本的优先级不同，则将第一HARQ-ACK码本或第二HARQ-ACK码本确定为第三HARQ-ACK码本。If the priority of the first HARQ-ACK codebook and the priority of the second HARQ-ACK codebook are the same, the third HARQ-ACK codebook is determined according to the first HARQ-ACK codebook and the second HARQ-ACK codebook; If the priority of the first HARQ-ACK codebook and the priority of the second HARQ-ACK codebook are different, the first HARQ-ACK codebook or the second HARQ-ACK codebook is determined as the third HARQ-ACK codebook .
具体地，如果第一HARQ-ACK码本和第二HARQ-ACK码本有重叠，则终端设备根据两份码本的优先级关系确定第三HARQ-ACK码本。若第一HARQ-ACK码本的优先级高于第二HARQ-ACK码本的优先级，则将第一HARQ-ACK码本确定为第三HARQ-ACK码本；若第二HARQ-ACK码本的优先级高于第一HARQ-ACK码本的优先级，则将第二HARQ-ACK码本确定为第三HARQ-ACK码本。Specifically, if the first HARQ-ACK codebook and the second HARQ-ACK codebook overlap, the terminal device determines the third HARQ-ACK codebook according to the priority relationship of the two codebooks. If the priority of the first HARQ-ACK codebook is higher than the priority of the second HARQ-ACK codebook, the first HARQ-ACK codebook is determined as the third HARQ-ACK codebook; if the second HARQ-ACK codebook The priority of the book is higher than the priority of the first HARQ-ACK codebook, and the second HARQ-ACK codebook is determined as the third HARQ-ACK codebook.
应理解，第一HARQ-ACK码本的优先级可以预先设置的。第一HARQ-ACK码本包含至少一个第一组播HARQ-ACK信息，和/或至少一个第二组播HARQ-ACK信息。若第一HARQ-ACK码本仅包含第一组播HARQ-ACK信息，则第一HARQ-ACK码本的优先级可以默认为第一组播优先级；若第一HARQ-ACK码本仅包含第二组播HARQ-ACK信息，则第一HARQ-ACK码本的优先级可以默认为第二组播优先级；若第一HARQ-ACK码本包含第一组播HARQ-ACK信息和第二组播HARQ-ACK信息，则第一HARQ-ACK 码本的优先级可以默认为第一组播优先级或第二组播优先级，比如第一HARQ-ACK码本的优先级可以默认为第一组播优先级或第二组播优先级中较高的优先级。It should be understood that the priority of the first HARQ-ACK codebook may be preset. The first HARQ-ACK codebook contains at least one first multicast HARQ-ACK information, and/or at least one second multicast HARQ-ACK information. If the first HARQ-ACK codebook only contains the first multicast HARQ-ACK information, the priority of the first HARQ-ACK codebook may be the first multicast priority by default; if the first HARQ-ACK codebook only contains the first multicast HARQ-ACK information The second multicast HARQ-ACK information, the priority of the first HARQ-ACK codebook can be the second multicast priority by default; if the first HARQ-ACK codebook contains the first multicast HARQ-ACK information and the second multicast HARQ-ACK information, the priority of the first HARQ-ACK codebook can be the first multicast priority or the second multicast priority by default, for example, the priority of the first HARQ-ACK codebook can be the default of the first The higher of the multicast priority or the second multicast priority.
另一种可能的设计是，第一HARQ-ACK码本的优先级可以是基站灵活配置的。例如，第一HARQ-ACK码本的优先级可以大于第一组播优先级，也可以小于第一组播优先级。Another possible design is that the priority of the first HARQ-ACK codebook may be flexibly configured by the base station. For example, the priority of the first HARQ-ACK codebook may be greater than or smaller than the first multicast priority.
应理解，第二HARQ-ACK码本的优先级可以预先设置的。第二HARQ-ACK码本包含至少一个第一单播HARQ-ACK信息，和/或至少一个第二单播HARQ-ACK信息。若第二HARQ-ACK码本仅包含第一单播HARQ-ACK信息，则第二HARQ-ACK码本的优先级可以默认为第一单播优先级；若第二HARQ-ACK码本仅包含第二单播HARQ-ACK信息，则第二HARQ-ACK码本的优先级可以默认为第二单播优先级；若第二HARQ-ACK码本包含第一单播HARQ-ACK信息和第二单播HARQ-ACK信息，则第二HARQ-ACK码本的优先级可以默认为第一单播优先级或第二单播优先级，比如第二HARQ-ACK码本的优先级可以默认为第一单播优先级或第二单播优先级中较高的优先级。It should be understood that the priority of the second HARQ-ACK codebook may be preset. The second HARQ-ACK codebook contains at least one first unicast HARQ-ACK information, and/or at least one second unicast HARQ-ACK information. If the second HARQ-ACK codebook only includes the first unicast HARQ-ACK information, the priority of the second HARQ-ACK codebook may be the first unicast priority by default; if the second HARQ-ACK codebook only includes the first unicast priority The second unicast HARQ-ACK information, the priority of the second HARQ-ACK codebook can be the second unicast priority by default; if the second HARQ-ACK codebook contains the first unicast HARQ-ACK information and the second Unicast HARQ-ACK information, the priority of the second HARQ-ACK codebook can default to the first unicast priority or the second unicast priority, for example, the priority of the second HARQ-ACK codebook can default to the first A unicast priority or a second unicast priority, whichever is higher.
另一种可能的设计是，第二HARQ-ACK码本的优先级可以是基站灵活配置的。例如，第二HARQ-ACK码本的优先级可以大于第一单播优先级，也可以小于第一单播优先级。Another possible design is that the priority of the second HARQ-ACK codebook may be flexibly configured by the base station. For example, the priority of the second HARQ-ACK codebook may be higher than or lower than the first unicast priority.
应理解，第一HARQ-ACK码本和第二HARQ-ACK码本重叠，指第一HARQ-ACK码本和第二HARQ-ACK码本在同一时间单元中反馈，或者承载第一HARQ-ACK码本和承载第二HARQ-ACK码本的时域资源全部或部分重叠。It should be understood that the overlapping of the first HARQ-ACK codebook and the second HARQ-ACK codebook means that the first HARQ-ACK codebook and the second HARQ-ACK codebook are fed back in the same time unit, or carry the first HARQ-ACK The codebook and the time-domain resources carrying the second HARQ-ACK codebook fully or partially overlap.
应理解，在本申请实施例中，组播码本和单播码本之间的优先级关系可以是基站灵活配置的，即第一组播优先级、第二组播优先级、第一单播优先级、第二单播优先级之间的优先级关系可能存在多种情况。例如，DCI中的优先级比特指示域使用1比特来表示组播调度数据的优先级，则组播码本可以包含两种优先级，其中，“1”表示第一组播优先级，“0”表示第二组播优先级。类似地，DCI中的优先级比特指示域使用1比特来表示单播调度数据的优先级，则单播码本可以包含两种优先级，其中，“1”表示第一单播优先级，“0”表示第二单播优先级。则组播和单播码本之间的优先级关系可以如下表一中所示：It should be understood that in this embodiment of the present application, the priority relationship between the multicast codebook and the unicast codebook may be flexibly configured by the base station, that is, the first multicast priority, the second multicast priority, the first The priority relationship between the unicast priority and the second unicast priority may exist in various situations. For example, the priority bit indication field in DCI uses 1 bit to represent the priority of multicast scheduling data, then the multicast codebook can contain two priorities, where "1" represents the first multicast priority, "0" ” indicates the second multicast priority. Similarly, the priority bit indication field in DCI uses 1 bit to represent the priority of unicast scheduling data, then the unicast codebook can contain two priorities, where "1" represents the first unicast priority, " 0" indicates the second unicast priority. Then the priority relationship between the multicast and unicast codebooks can be shown in Table 1 below:

Figure PCTCN2021072293-appb-000001
Figure PCTCN2021072293-appb-000002
Figure PCTCN2021072293-appb-000002
应理解，表一中的“>”代表优先级“高于”，“＝”代表优先级“相等”。例如“第一组播优先级＝第一单播优先级>第二组播优先级＝第二单播优先级”代表“第一单播优先级与第一单播优先级相等，第二组播优先级与第二单播优先级相等，第一单播优先级高于第二单播优先级”。It should be understood that ">" in Table 1 represents priority "higher than", and "=" represents priority "equal". For example, "first multicast priority = first unicast priority > second multicast priority = second unicast priority" means "the first unicast priority is equal to the first unicast priority, the second group The unicast priority is equal to the second unicast priority, and the first unicast priority is higher than the second unicast priority”.
应理解，表一仅用于举例说明。组播码本的优先级可能存在其他的表示方式。例如，用“0”表示第一组播优先级，用“1”表示第二组播优先级；或者，DCI使用两个或多个比特位表示组播业务数据的优先级等，本申请对此不作限定。It should be understood that Table 1 is for illustration only. There may be other representations for the priority of the multicast codebook. For example, "0" is used to represent the first multicast priority, and "1" is used to represent the second multicast priority; or, DCI uses two or more bits to represent the priority of multicast service data, etc. This is not limited.
因此，本申请实施例的传输反馈信息的方法，当根据组播HARQ-ACK信息确定的码本和根据单播HARQ-ACK信息确定的码本发生冲突时，通过弃用两份码本中优先级较低的码本，可以解决组播HARQ-ACK信息和单播HARQ-ACK信息之间的冲突，保证终端设备能够正常反馈不同下行调度数据的HARQ-ACK信息，从而提高传输可靠性。Therefore, in the method for transmitting feedback information according to the embodiment of the present application, when the codebook determined according to the multicast HARQ-ACK information and the codebook determined according to the unicast HARQ-ACK information collide, the priority of the two codebooks is discarded. The lower-level codebook can solve the conflict between multicast HARQ-ACK information and unicast HARQ-ACK information, and ensure that terminal equipment can normally feed back HARQ-ACK information of different downlink scheduling data, thereby improving transmission reliability.
在S230中，可选地，该根据所述第一HARQ-ACK码本和所述第二HARQ-ACK码本，确定第三HARQ-ACK码本，包括：In S230, optionally, determining a third HARQ-ACK codebook according to the first HARQ-ACK codebook and the second HARQ-ACK codebook, including:
终端设备确定第三HARQ-ACK码本，第三HARQ-ACK码本包括第一HARQ-ACK码本和第二HARQ-ACK码本。The terminal device determines a third HARQ-ACK codebook, and the third HARQ-ACK codebook includes the first HARQ-ACK codebook and the second HARQ-ACK codebook.
具体地，如果第一HARQ-ACK码本和第二HARQ-ACK码本有重叠，则终端设备将第一HARQ-ACK码本和第二HARQ-ACK码本复用为第三HARQ-ACK码本。第一HARQ-ACK码本和第二HARQ-ACK码本重叠，指第一HARQ-ACK码本和第二HARQ-ACK码本在同一时间单元中反馈，或者，第一HARQ-ACK码本和第二HARQ-ACK码本重叠，指承载第一HARQ-ACK码本和承载第二HARQ-ACK码本的时域资源全部或部分重叠，例如，第一HARQ-ACK码本和第二HARQ-ACK码本在同一时隙中占用的部分符号重叠。Specifically, if the first HARQ-ACK codebook and the second HARQ-ACK codebook overlap, the terminal device multiplexes the first HARQ-ACK codebook and the second HARQ-ACK codebook into a third HARQ-ACK code Book. The first HARQ-ACK codebook and the second HARQ-ACK codebook overlap, which means that the first HARQ-ACK codebook and the second HARQ-ACK codebook are fed back in the same time unit, or, the first HARQ-ACK codebook and the second HARQ-ACK codebook are fed back in the same time unit. The second HARQ-ACK codebook overlaps, which means that the time domain resources that carry the first HARQ-ACK codebook and the second HARQ-ACK codebook overlap in whole or in part. Some symbols occupied by the ACK codebook in the same time slot overlap.
因此，本申请实施例的传输反馈信息的方法，当根据组播HARQ-ACK信息确定的码本和根据单播HARQ-ACK信息确定的码本发生冲突时，通过复用两份码本，可以解决组播、单播的HARQ-ACK信息的冲突，同时能够尽可能地保留传输反馈信息的完整性，进一步提升传输可靠性。Therefore, in the method for transmitting feedback information according to the embodiment of the present application, when the codebook determined according to the multicast HARQ-ACK information and the codebook determined according to the unicast HARQ-ACK information collide, by multiplexing the two codebooks, it is possible to It solves the conflict between multicast and unicast HARQ-ACK information, and at the same time preserves the integrity of transmission feedback information as much as possible, further improving transmission reliability.
