Description

Technical Field

[0001] This application belongs to the field of communication technology, and specifically relates to a hybrid automatic repeat request feedback processing method, apparatus and terminal. Background Technology

[0002] Currently, the codebook used in the feedback mechanism based on the one-shot HARQ-ACK codebook can be called the type 3 codebook, which feeds back HARQ-ACK information for each possible codeword of the configuration HARQ process on all carriers currently configured for the terminal.

[0003] To reduce the size of the type 3 codebook, an enhanced type 3 codebook is introduced into this feedback mechanism. The base station configures different enhanced type 3 codebooks through higher-layer parameters. Each codebook contains a specific serving cell index and a HARQ process identifier configured by Radio Resource Control (RRC) signaling. When providing feedback, the terminal only needs to feed back the serving cell corresponding to that codebook and the HARQ-ACK information corresponding to the HARQ process.

[0004] However, when two HARQ-ACK messages need to be transmitted in the same time unit (time slot / sub-time slot), and one of the HARQ-ACK messages requires a type 3 codebook or an enhanced type 3 codebook, such as when a terminal (User Equipment, UE) simultaneously receives unicast and multicast services, how to perform HARQ-ACK feedback in that time unit has become an urgent problem to be solved. Summary of the Invention

[0005] This application provides a hybrid automatic repeat request feedback processing method, apparatus, and terminal, which can solve the problem of how to implement feedback when at least one HARQ-ACK message is generated based on a specific codebook and two HARQ-ACK messages need to be transmitted in the same time unit.

[0027] The hybrid automatic repeat request feedback processing method, apparatus and terminal provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0028] like Figure 2 As shown in the figure, a hybrid automatic repeat request feedback processing method according to an embodiment of this application includes:

[0029] Step 201: When the first Hybrid Automatic Repeat Request (HARQ-ACK) and the second HARQ-ACK are in the same time unit, and the codebook used by the first HARQ-ACK is the first codebook, the terminal generates HARQ-ACK information for the first HARQ-ACK and the second HARQ-ACK according to the first codebook, or generates HARQ-ACK information according to the priority of the first HARQ-ACK and the priority of the second HARQ-ACK.

[0030] Here, the first HARQ-ACK and the second HARQ-ACK can be scheduled by their respective corresponding information, such as the first information scheduling the first HARQ-ACK and the second information scheduling the second HARQ-ACK. Of course, the second HARQ-ACK can also be a semi-persistent scheduling (SPS) HARQ-ACK, that is, a HARQ-ACK for a Physical Downlink Shared Channel (PDSCH) that is not scheduled by a Physical Downlink Control Channel (PDCCH), i.e., an SPS PDSCH. Specifically, the first HARQ-ACK requires the use of a first codebook to generate its corresponding PDCCH / PDSCH HARQ-ACK. For example, the higher-layer signaling configuration may specify that the codebook type of the first HARQ-ACK includes the first codebook and / or Downlink Control Information (DCI) triggering the first codebook. The second HARQ-ACK requires the use of the first codebook or other codebooks to generate its corresponding PDCCH / PDSCH HARQ-ACK.

[0031] Thus, according to step 201, when the first HARQ-ACK and the second HARQ-ACK are in the same time unit, and the codebook used by the first HARQ-ACK is the first codebook, one approach is to generate the HARQ-ACK information of the first HARQ-ACK and the second HARQ-ACK only based on the first codebook, thereby reducing redundant information in the HARQ-ACK feedback; another approach is to generate the HARQ-ACK information based on the priority of the first HARQ-ACK and the priority of the second HARQ-ACK, thereby ensuring the reliability of the high-priority HARQ-ACK.

[0032] It should be understood that the first HARQ-ACK and the second HARQ-ACK are in the same time unit, which can be understood as the first HARQ-ACK and the second HARQ-ACK being triggered / scheduled within one time unit.

[0033] In this embodiment, a higher priority for HARQ-ACK indicates that HARQ-ACK is fed back more preferentially. The priority of HARQ-ACK can be represented using a priority index, such as 0 or 1. For example, if the priority indices are the same, they indicate the same priority; a higher priority index value indicates a higher priority.

[0034] Optionally, in this embodiment, the first HARQ-ACK is a unicast HARQ-ACK, and the second HARQ-ACK is a multicast HARQ-ACK. Specifically, the first HARQ-ACK is a unicast HARQ-ACK, meaning it is a HARQ-ACK that feeds back a unicast PDCCH / PDSCH, or it can be a HARQ-ACK triggered / scheduled by a unicast PDCCH / PDSCH. The second HARQ-ACK is a groupcast, multicast, or group-common HARQ-ACK, meaning it is a HARQ-ACK that feeds back a groupcast / multicast / group-common PDCCH / PDSCH, or it can be a HARQ-ACK triggered / scheduled by a groupcast / multicast / group-common PDCCH / PDSCH. Of course, the first HARQ-ACK can also be a multicast HARQ-ACK, and the second HARQ-ACK can also be a unicast HARQ-ACK.

[0035] It should be noted that multicast in this invention can also be called groupcast or group common transmission, and no distinction is made in this invention.

[0036] Optionally, in this embodiment, the first codebook is a type 3 codebook or an enhanced type 3 codebook.

[0037] For example, in a certain time unit (such as a time slot / sub-time slot), if a terminal is triggered to send a unicast HARQ-ACK (first HARQ-ACK), and the unicast HARQ-ACK uses a type 3 codebook or an enhanced type 3 codebook (first codebook), and if the terminal is also triggered / scheduled to send a multicast HARQ-ACK (second HARQ-ACK) in the same time unit, and the multicast HARQ-ACK uses a type 1 codebook or a type 2 codebook (second codebook), then the terminal will send the feedback as follows:

[0038] Method 1: The terminal generates unicast HARQ-ACK and multicast HARQ-ACK information based solely on the type 3 codebook or enhanced type 3 codebook. Specifically, the terminal generates the type 3 codebook or enhanced type 3 codebook based on the serving cell and the HARQ process. For a given HARQ process number, if the terminal receives the corresponding PDCCH / PDSCH (whether unicast or multicast), the terminal sets the HARQ-ACK information corresponding to that HARQ process based on the decoding result of the PDCCH / PDSCH. If decoding is successful, ACK is set; otherwise, NACK is set. Here, the unicast HARQ-ACK codebook generated and returned by the terminal can also contain HARQ-ACK information for the multicast PDCCH / PDSCH.

[0039] Method 2: The terminal will generate HARQ-ACK information based on the priority of unicast HARQ-ACK and multicast HARQ-ACK.

[0040] In this embodiment, generating HARQ-ACK information for the first HARQ-ACK and the second HARQ-ACK based on the first codebook can be understood as using the first codebook to generate feedback HARQ-ACK information for the first HARQ-ACK and the second HARQ-ACK.

[0041] Of course, in this embodiment, if the first HARQ-ACK and the second HARQ-ACK are in the same time unit, and the codebook used by the first HARQ-ACK is the first codebook, the terminal will generate HARQ-ACK information for the first HARQ-ACK and the second HARQ-ACK based on the first codebook when the first resource and the second resource overlap. When the first resource and the second resource do not overlap, the terminal can generate their respective HARQ-ACK information.

[0042] Therefore, optionally, the terminal generates HARQ-ACK information for the first HARQ-ACK and the second HARQ-ACK based on the first codebook, including:

[0043] Based on the HARQ process identifier, the terminal generates an acknowledgment or denial message according to the decoding result of the corresponding Physical Downlink Shared Channel (PDSCH) or Physical Downlink Control Channel (PDCCH) when it receives the corresponding PDSCH or PDCCH; or, if it does not receive the corresponding PDSCH or PDCCH, it generates a denial message.

[0044] In other words, when constructing the HARQ-ACK information corresponding to the first codebook, for a certain HARQ process ID (which can also represent the HARQ process number), if the terminal receives the PDSCH / PDCCH corresponding to the HARQ process ID, regardless of whether the PDSCH / PDCCH is unicast or multicast, the terminal will generate an ACK or NACK message based on the decoding result of the PDSCH / PDCCH; if the terminal receives the PDSCH / PDCCH corresponding to the HARQ process ID, regardless of whether the PDSCH / PDCCH is unicast or multicast, the terminal will generate a NACK message.

[0045] Specifically, an ACK is generated when the decoding result of the PDSCH / PDCCH indicates successful decoding; a NACK is generated when the decoding result of the PDSCH / PDCCH indicates failure. A NACK is generated when no corresponding PDCCH / PDSCH is received.

[0046] Optionally, the terminal generates HARQ-ACK information for the first HARQ-ACK and the second HARQ-ACK based on the first codebook, further including:

[0047] The terminal transmits the HARQ-ACK information of the first HARQ-ACK and the second HARQ-ACK generated through the first resource transmission;

[0048] The first resource is the transmission resource of the first HARQ-ACK.

[0049] Alternatively, the first resource may be the transmission resource of the unicast HARQ-ACK.

[0050] That is, for the HARQ-ACK information generated by method one in the above example, the transmission resources of the first HARQ-ACK can be used to complete the feedback.

[0051] Optionally, the first HARQ-ACK and the second HARQ-ACK mentioned above have the same priority.

[0052] Furthermore, considering the enhanced type 3 codebook, each codebook contains a specific serving cell index and HARQ process ID. Therefore, optionally, in this embodiment, the first HARQ-ACK and the second HARQ-ACK are in the same time unit, and the codebook used by the first HARQ-ACK is an enhanced type 3 codebook. The method further includes at least one of the following:

[0053] If the HARQ process identifier corresponding to the enhancement type 3 codebook includes all HARQ process identifiers corresponding to the second HARQ-ACK, then the terminal generates HARQ-ACK information for the first HARQ-ACK and the second HARQ-ACK according to the enhancement type 3 codebook, or generates HARQ-ACK information according to the priority of the first HARQ-ACK and the priority of the second HARQ-ACK.

[0054] If the HARQ process identifier corresponding to the enhancement type 3 codebook does not include all the HARQ process identifiers corresponding to the second HARQ-ACK, then the terminal generates the HARQ-ACK information of the first HARQ-ACK according to the enhancement type 3 codebook, and generates the HARQ-ACK information of the second HARQ-ACK according to the second codebook; wherein, the second codebook is the codebook used by the second HARQ-ACK indicated by the network-side device.

[0055] In other words, if the first codebook is an enhanced type 3 codebook, the terminal determines whether the HARQ process ID corresponding to the enhanced type 3 codebook includes the HARQ process ID corresponding to the second HARQ-ACK.

[0056] When the HARQ process ID corresponding to the enhanced type 3 codebook includes all the HARQ process IDs corresponding to the second HARQ-ACK, the HARQ-ACK information of the first HARQ-ACK and the second HARQ-ACK is generated according to the enhanced type 3 codebook, or the HARQ-ACK information is generated according to the priority of the first HARQ-ACK and the priority of the second HARQ-ACK.

[0057] When the HARQ process ID corresponding to the enhanced type 3 codebook does not include all the HARQ process IDs corresponding to the second HARQ-ACK (i.e., at least one HARQ process ID corresponding to the second HARQ-ACK is not included in the HARQ process IDs corresponding to the enhanced type 3 codebook), the respective HARQ-ACK information is generated according to their respective codebooks.

[0058] For example, in a certain time unit (time slot / sub-time slot), if the terminal is triggered / scheduled for a unicast HARQ-ACK (first HARQ-ACK) and the unicast HARQ-ACK uses an enhanced type 3 codebook, and if the terminal is also triggered / scheduled for a multicast HARQ-ACK (second HARQ-ACK) in the same time unit, and the multicast HARQ-ACK uses a type 1 or type 2 codebook, then the terminal will respond as follows:

[0059] The terminal determines whether the HARQ process ID corresponding to the enhanced type 3 codebook includes the HARQ process ID corresponding to the second HARQ-ACK.

[0060] When the HARQ process ID corresponding to the enhanced type 3 codebook includes all HARQ process IDs corresponding to the second HARQ-ACK, HARQ-ACK information can be generated according to method one or method two of the above example;

[0061] When the HARQ process ID corresponding to the enhanced type 3 codebook does not include all the HARQ process IDs corresponding to the second HARQ-ACK, the HARQ-ACK information for unicast HARQ-ACK is generated according to the enhanced type 3 codebook, and the HARQ-ACK information for multicast HARQ-ACK is generated according to the type 1 codebook.

[0062] Here, the specific implementation of generating the first HARQ-ACK and the second HARQ-ACK information based on the enhanced type 3 codebook, that is, the specific implementation of generating the first HARQ-ACK and the second HARQ-ACK information based on the first codebook by the terminal mentioned above, the first codebook is the implementation of the enhanced type 3 codebook, which will not be described in detail here.

[0063] It should be noted that in this embodiment, the HARQ process ID corresponding to the enhanced type 3 codebook includes all HARQ process IDs corresponding to the second HARQ-ACK. This is determined based on the fact that the HARQ process ID corresponding to the enhanced type 3 codebook and the HARQ process ID corresponding to the second HARQ-ACK belong to the same serving cell. If the HARQ process ID corresponding to the enhanced type 3 codebook and the HARQ process ID corresponding to the second HARQ-ACK are from different serving cells, the HARQ process IDs are not included even if they are the same. That is, only the same HARQ process IDs from the same serving cell belong to the same HARQ process.

[0064] It should also be noted that when the HARQ process ID corresponding to the second HARQ-ACK is included in the HARQ process ID corresponding to the enhanced type 3 codebook, when the UE generates the enhanced type 3 codebook, if a certain HARQ process ID corresponds to the second HARQ-ACK, the UE can set ACK / NACK or set NACK according to the decoding result.

[0065] In addition, optionally, in this embodiment, the terminal generates HARQ-ACK information based on the priority of the first HARQ-ACK and the priority of the second HARQ-ACK, including at least one of the following:

[0066] When the priority of the first HARQ-ACK is greater than or equal to the priority of the second HARQ-ACK, the terminal generates HARQ-ACK information for the first HARQ-ACK and the second HARQ-ACK according to the first codebook.

[0067] When the priority of the first HARQ-ACK is lower than the priority of the second HARQ-ACK, the terminal generates HARQ-ACK information for the first HARQ-ACK based on the first codebook, and generates HARQ-ACK information for the second HARQ-ACK based on the second codebook; wherein, the second codebook is the codebook used by the second HARQ-ACK as indicated by the network-side device.

[0068] Here, HARQ-ACK information is generated in different ways depending on whether the priority of the first HARQ-ACK is greater than or equal to the priority of the second HARQ-ACK, or whether the priority of the first HARQ-ACK is less than the priority of the second HARQ-ACK.

[0069] Continuing with the second method in the example above, when the priority of the first HARQ-ACK is greater than or equal to the priority of the second HARQ-ACK, the HARQ-ACK information is generated according to method one; when the priority of the first HARQ-ACK is less than the priority of the second HARQ-ACK, the HARQ-ACK information for unicast HARQ-ACK is generated according to the type 3 codebook or the enhanced type 3 codebook, and the HARQ-ACK information for multicast HARQ-ACK is generated according to the type 1 or type 2 codebook.

[0070] Optionally, in this embodiment, the terminal generates HARQ-ACK information based on the priority of the first HARQ-ACK and the priority of the second HARQ-ACK, including at least one of the following:

[0071] When the priority of the first HARQ-ACK is equal to the priority of the second HARQ-ACK, the terminal generates HARQ-ACK information for the first HARQ-ACK and the second HARQ-ACK according to the first codebook.

[0072] When the priority of the first HARQ-ACK is not equal to the priority of the second HARQ-ACK, the terminal generates HARQ-ACK information for the first HARQ-ACK based on the first codebook, and generates HARQ-ACK information for the second HARQ-ACK based on the second codebook; wherein, the second codebook is the codebook used by the second HARQ-ACK as indicated by the network-side device.

[0073] Here, HARQ-ACK information is generated in different ways depending on whether the priority of the first HARQ-ACK is equal to the priority of the second HARQ-ACK or the priority of the first HARQ-ACK is not equal to the priority of the second HARQ-ACK.

[0074] Continuing with the second method in the example above, when the priority of the first HARQ-ACK is equal to the priority of the second HARQ-ACK, the HARQ-ACK information is generated according to method one; when the priority of the first HARQ-ACK is not equal to the priority of the second HARQ-ACK, the HARQ-ACK information for unicast HARQ-ACK is generated according to the type 3 codebook or the enhanced type 3 codebook, and the HARQ-ACK information for multicast HARQ-ACK is generated according to the type 1 or type 2 codebook.

[0075] Optionally, the terminal generates HARQ-ACK information for the first HARQ-ACK based on the first codebook and generates HARQ-ACK information for the second HARQ-ACK based on the second codebook, further comprising:

[0076] In the case where the first resource and the second resource overlap, the terminal transmits the HARQ-ACK information of the second HARQ-ACK through the second resource;

[0077] When the first resource and the second resource do not overlap, the terminal transmits the HARQ-ACK information of the first HARQ-ACK through the first resource and transmits the HARQ-ACK information of the second HARQ-ACK through the second resource.

[0078] Wherein, the first resource is the transmission resource of the first HARQ-ACK;

[0079] The second resource is the transmission resource of the second HARQ-ACK.

[0080] In other words, for HARQ-ACKs of different priorities, if each HARQ-ACK codebook is generated separately, when the first resource and the second resource overlap, the terminal will only transmit the HARQ-ACK information of the generated second HARQ-ACK on the second resource, and the terminal will discard the HARQ-ACK information of the first HARQ-ACK; when the first resource and the second resource do not overlap, the terminal will transmit the HARQ-ACK information of the generated first HARQ-ACK on the first resource and transmit the HARQ-ACK information of the generated second HARQ-ACK on the second resource.

[0081] In this embodiment, the first resource and the second resource can be the Physical Uplink Control Channel (PUCCH). Overlapping first and second resources means that the time-domain resources of the two PUCCHs overlap, and non-overlapping first and second resources means that the time-domain resources of the two PUCCHs do not overlap. The overlap of time-domain resources includes partial overlap or full overlap.

[0082] For example, continuing with the above example method 2, and generating unicast HARQ-ACK information according to type 3 codebook or enhanced type 3 codebook, and generating multicast HARQ-ACK information according to type 1 or type 2 codebook, if the first resource and the second resource overlap, and the unicast HARQ-ACK has a lower priority and the multicast HARQ-ACK has a higher priority, then the terminal discards the generated unicast HARQ-ACK information and transmits the generated multicast HARQ-ACK information; if the first resource and the second resource do not overlap, then the terminal transmits the two generated HARQ-ACK information respectively.

[0083] Of course, if the first resource and the second resource overlap, and the unicast HARQ-ACK has a higher priority and the multicast HARQ-ACK has a lower priority, then the terminal will transmit the HARQ-ACK information that has generated the unicast HARQ-ACK and discard the HARQ-ACK information that has generated the multicast HARQ-ACK.

[0084] In addition, optionally, in this embodiment, the terminal generates the HARQ-ACK information of the first HARQ-ACK based on the enhancement type 3 codebook, and generates the HARQ-ACK information of the second HARQ-ACK based on the second codebook, further including at least one of the following:

[0085] The terminal determines the target resource based on whether the priorities of the first HARQ-ACK and the second HARQ-ACK are the same, and transmits HARQ-ACK information through the target resource;

[0086] The terminal transmits the HARQ-ACK information of the first HARQ-ACK through the first resource and transmits the HARQ-ACK information of the second HARQ-ACK through the second resource;

[0087] Wherein, the first resource is the transmission resource of the first HARQ-ACK;

[0088] The second resource is the transmission resource of the second HARQ-ACK.

[0089] That is, when the first codebook is an enhanced type 3 codebook, the terminal determines whether the HARQ process ID corresponding to the enhanced type 3 codebook includes the HARQ process ID corresponding to the second HARQ-ACK. If the HARQ process ID corresponding to the enhanced type 3 codebook does not include all the HARQ process IDs corresponding to the second HARQ-ACK, the terminal generates its own HARQ-ACK information according to the respective codebooks of each HARQ-ACK.

[0090] On the one hand, the terminal can determine the target resource by whether the priority of the first HARQ-ACK is the same as that of the second HARQ-ACK, and then use the target resource to provide feedback.

[0091] On the other hand, each terminal uses its own HARQ-ACK transmission resources to transmit its own HARQ-ACK information.

[0092] Optionally, the terminal determines the target resource based on whether the priorities of the first HARQ-ACK and the second HARQ-ACK are the same, and transmits target information through the target resource, including at least one of the following:

[0093] If the priority of the first HARQ-ACK is different from that of the second HARQ-ACK, and if the first resource and the second resource overlap, the terminal will use the resource with the higher priority HARQ-ACK as the target resource and transmit the HARQ-ACK information of the higher priority HARQ-ACK through the target resource.

[0094] If the priority of the first HARQ-ACK is different from that of the second HARQ-ACK, and if the first resource and the second resource do not overlap, the terminal transmission transmits the HARQ-ACK information of the first HARQ-ACK through the first resource and transmits the HARQ-ACK information of the second HARQ-ACK through the second resource.

[0095] When the priority of the first HARQ-ACK is the same as the priority of the second HARQ-ACK, the terminal selects the first resource, the second resource, or the third resource as the target resource, and transmits the information obtained by concatenating the HARQ-ACK information of the first HARQ-ACK and the HARQ-ACK information of the second HARQ-ACK through the target resource; the third resource is a resource determined based on the number of bits of the concatenated information.

[0096] Therefore, when the first codebook is an enhanced type 3 codebook, the terminal determines whether the HARQ process ID corresponding to the enhanced type 3 codebook includes the HARQ process ID corresponding to the second HARQ-ACK. If the HARQ process ID corresponding to the enhanced type 3 codebook does not include all the HARQ process IDs corresponding to the second HARQ-ACK, the terminal generates its respective HARQ-ACK information according to the codebooks of each HARQ-ACK.

[0097] If the priority of the first HARQ-ACK is different from that of the second HARQ-ACK, and the first and second resources overlap, the terminal will use the resource of the HARQ-ACK with higher priority in the first and second HARQ-ACK as the target resource, and transmit the HARQ-ACK information of the HARQ-ACK with higher priority in the first and second HARQ-ACK through the target resource, while discarding the HARQ-ACK information of the HARQ-ACK with lower priority in the first and second HARQ-ACK.

[0098] If the priority of the first HARQ-ACK is different from that of the second HARQ-ACK, and the first resource and the second resource do not overlap, the terminal will use the first resource and the second resource as target resources and transmit the corresponding HARQ-ACK information respectively.

[0099] If the priority of the first HARQ-ACK is the same as that of the second HARQ-ACK, the terminal can select the first resource, the second resource, or the third resource as the target resource to transmit the information obtained by concatenating the two generated HARQ-ACK messages.

[0100] Here, if the two HARQ-ACKs are unicast HARQ-ACK and multicast HARQ-ACK respectively, the concatenation of the two generated HARQ-ACK messages is to concatenate the HARQ-ACK message of multicast HARQ-ACK after the HARQ-ACK message of unicast HARQ-ACK.

[0101] It should be noted that in this embodiment, the third resource is also a PUCCH resource. The third resource can be determined based on the number of bits after concatenation; alternatively, it can be determined from the PUCCH resources configured for unicast HARQ-ACK.

[0102] The application of the embodiments of this application will be described below with reference to specific scenarios:

[0103] like Figure 3 As shown, PDCCH1 is a unicast PDCCH, and its corresponding HARQ-ACK (first HARQ-ACK) is fed back in time slot n+1. PDCCH2 is a multicast PDCCH, and its corresponding HARQ-ACK (second HARQ-ACK) is also fed back in time slot n+1. That is, the transmission resource PUCCH1 for the HARQ-ACK corresponding to PDCCH1 is in time slot n+1, and the transmission resource PUCCH2 for the HARQ-ACK corresponding to PDCCH2 is also in time slot n+1. When the HARQ-ACK corresponding to the unicast PDCCH / PDSCH is configured with a type 3 codebook or an enhanced type 3 codebook, the terminal can feed back the response in the following manner:

[0104] For type 3 codebook,

[0105] Method 1-1: Regardless of whether the priority of the type 3 codebook (unicast HARQ-ACK) is low / high (small / large) priority, and regardless of whether PUCCH1 and PUCCH2 overlap (the terminal does not need to determine whether PUCCH overlaps), the UE only constructs and transmits the type 3 codebook.

[0106] It should be noted that the UE here only constructs and transmits the type 3 codebook. When constructing the type 3 codebook, as mentioned above, if the UE receives the corresponding PDCCH / PDSCH (regardless of whether it is unicast or multicast) for a certain HARQ process, the UE generates the corresponding HARQ-ACK information according to the decoding result of the PDCCH / PDSCH.

[0107] Method 1-2: Regardless of whether the priority of the type 3 codebook (unicast HARQ-ACK) is low or high, if PUCCH1 and PUCCH2 overlap, the terminal only constructs and transmits the type 3 codebook. If PUCCH1 and PUCCH2 do not overlap, the terminal constructs and transmits the HARQ-ACK information for unicast HARQ-ACK and the HARQ-ACK information for multicast HARQ-ACK respectively, that is, it constructs and transmits the type 3 codebook and the multicast HARQ-ACK codebook respectively.

[0108] It should be noted that here the UE constructs and transmits the type 3 codebook. When constructing the type 3 codebook, as mentioned above, if the PDCCH / PDSCH corresponding to a certain HARQ process is multicast, the UE can generate the corresponding HARQ-ACK information or generate NACK information according to the decoding result of the PDCCH / PDSCH.

[0109] Method 2: If the priority of unicast HARQ-ACK is higher than that of multicast HARQ-ACK, the terminal only constructs and transmits the type 3 codebook. If the priority of multicast HARQ-ACK is higher than that of unicast HARQ-ACK, the terminal constructs and transmits both the unicast HARQ-ACK and multicast HARQ-ACK information, i.e., constructs and transmits both the type 3 codebook and the multicast HARQ-ACK codebook.

[0110] Method 3: If the priority of unicast HARQ-ACK is equal to the priority of multicast HARQ-ACK, the terminal only constructs and transmits the type 3 codebook. If the priority of multicast HARQ-ACK is different from that of unicast HARQ-ACK, the terminal constructs and transmits the HARQ-ACK information for unicast HARQ-ACK and multicast HARQ-ACK separately, i.e., constructs and transmits the type 3 codebook and multicast HARQ-ACK codebook separately. It is worth noting that when constructing and transmitting the type 3 codebook and multicast HARQ-ACK codebook separately, if the PUCCH time-domain resources for transmitting the two HARQ-ACKs overlap, the UE needs to discard the lower-priority PUCCH and its HARQ-ACK information, and transmit the higher-priority PUCCH and its HARQ-ACK information.

[0111] For enhancing the type 3 codebook,

[0112] In addition to methods 1-1, 1-2, and method 2 (which requires replacing type 3codebook with enhanced type3codebook), the following methods can also be used:

[0113] Method 4: Based on whether the HARQ process ID corresponding to the multicast HARQ-ACK is included in enhancement type 3,

[0114] If the HARQ process IDs corresponding to multicast HARQ-ACK are all included in the HARQ process IDs included in enhanced type 3, then use method 1-1, method 1-2, or method 2 as described above.

[0115] If at least one HARQ process ID corresponding to a multicast HARQ-ACK is not included in the HARQ process IDs included in enhancement type 3, then the HARQ-ACK information for unicast HARQ-ACK and multicast HARQ-ACK is constructed separately.

[0116] 1) When PUCCH1 and PUCCH2 overlap and the two PUCCHs have different priorities (which can also be understood as the multicast HARQ-ACK and unicast HARQ-ACK having different priorities), the terminal discards the lower-priority PUCCH and transmits the higher-priority PUCCH. If the PUCCH priorities are the same, the HARQ-ACK is multiplexed onto one PUCCH, where the multicast HARQ-ACK is concatenated after the unicast HARQ-ACK codebook.

[0117] 2) When PUCCH1 and PUCCH2 do not overlap, the terminal transmits two PUCCHs respectively.

[0118] It is worth noting that if part of the HARQ process ID of the multicast HARQ-ACK is included in the enhanced type 3 codebook of the unicast, then when the UE constructs the enhanced type 3 codebook, if the PDCCH / PDSCH corresponding to a certain HARQ process is multicast, the UE can generate ACK / NACK information or directly generate NACK information based on the decoding result of the multicast PDCCH / PDSCH.

[0119] In summary, the method of this application embodiment, for the case where the first HARQ-ACK and the second HARQ-ACK are in the same time unit, and the codebook used by the first HARQ-ACK is the first codebook, has two approaches: one is to generate the HARQ-ACK information of the first HARQ-ACK and the second HARQ-ACK only based on the first codebook, thereby reducing redundant information in the HARQ-ACK feedback; the other is to generate the HARQ-ACK information based on the priority of the first HARQ-ACK and the priority of the second HARQ-ACK, thereby ensuring the reliability of the high-priority HARQ-ACK.

[0120] The hybrid automatic repeat request feedback processing method provided in this application can be executed by a hybrid automatic repeat request feedback processing device. This application uses the execution of the hybrid automatic repeat request feedback processing method by the hybrid automatic repeat request feedback processing device as an example to illustrate the hybrid automatic repeat request feedback processing device provided in this application.

[0126] If the HARQ process identifier corresponding to the enhancement type 3 codebook does not include all the HARQ process identifiers corresponding to the second HARQ-ACK, then the HARQ-ACK information of the first HARQ-ACK is generated according to the enhancement type 3 codebook, and the HARQ-ACK information of the second HARQ-ACK is generated according to the second codebook; wherein, the second codebook is the codebook used by the second HARQ-ACK indicated by the network-side device.

[0153] For cases where the first HARQ-ACK and the second HARQ-ACK are in the same time unit, and the codebook used by the first HARQ-ACK is the first codebook, the device has two approaches: one is to generate the HARQ-ACK information for the first HARQ-ACK and the second HARQ-ACK only based on the first codebook, thus reducing redundant information in the HARQ-ACK feedback; the other is to generate the HARQ-ACK information based on the priority of the first HARQ-ACK and the priority of the second HARQ-ACK, thus ensuring the reliability of the high-priority HARQ-ACK.
