- the existing unicast HARQ scheduling and The feedback indication mechanism is not suitable for cellular broadcast and multicast feedback.
- Sidelink is based on the terminal-to-terminal communication link.
- Sidelink broadcast multicast communication there are two main Sidelink HARQ feedback modes:
- Mode 1 HARQ NACK-based feedback mode: In this mode, all receiving terminals share the same physical side link feedback channel (PSFCH) resource for HARQ-ACK feedback. If any terminal fails to correctly receive the physical side link shared channel (PSSCH) used to transmit service data, it sends HARQ NACK information on the shared PSFCH resource. For this method, the base station cannot identify which terminal has fed back the NACK, so it cannot adjust the link quality of these NACK-backed terminals adaptively. That is, the channel quality information cannot be effectively used, resulting in a waste of wireless air interface resources. When the broadcast/multicast scheduling signaling is not detected, the terminal will not feed back NACK, so the base station will think that all terminals have received the data correctly, which will cause the performance of broadcast/multicast data transmission to deteriorate.
- PSFCH physical side link feedback channel
- Mode 2 HARQ ACK/NACK feedback mode: In this mode, each receiving terminal has its own independent PSFCH resource, and each receiving terminal sends HARQ ACK on the corresponding PSFCH resource according to whether it receives the PSSCH correctly or not. /NACK information; the main application scenario is when there are fewer terminals in the group. For this method, it is necessary to allocate uplink feedback resources to all terminals. When the number of terminals receiving the broadcast multicast service is relatively large, it will be more difficult to allocate uplink channel resources; different receiving ends and base stations have different locations, in order to effectively feedback HARQ -ACK, some need to occupy 2 symbols, some need to occupy 4 symbols, and some even need to occupy 14 symbols. However, the resource allocation of the existing scheme is a unified format, which cannot satisfy the cellular feedback HARQ-ACK Demand.
- the present disclosure provides the following embodiments:
- Step 101 Receive the broadcast multicast scheduling signaling sent by the base station, and determine the uplink resource corresponding to the unicast.
- the uplink resources corresponding to unicast can be used to feed back unicast HARQ-ACK, and the uplink resources include PUCCH resources or PUSCH resources.
- Step 102 When it is detected that the preset condition is met, multiplex the first HARQ-ACK codebook corresponding to the broadcast multicast scheduling signaling to the uplink resource corresponding to the unicast.
- the preset condition is that the HARQ-ACK feedback time slot indicated by the broadcast multicast scheduling signaling and the time slot where the uplink resource is located simultaneously exist in the preset window.
- the terminal receives the broadcast multicast scheduling signaling sent by the base station, if the HARQ-ACK feedback time slot indicated by the broadcast multicast scheduling signaling and the uplink resource corresponding to the unicast exist in the preset window at the same time Time slot, the first HARQ-ACK codebook corresponding to broadcast multicast scheduling signaling is multiplexed onto the uplink resource corresponding to unicast, which simplifies the protocol design and complexity of the HARQ-ACK feedback from broadcast and multicast, and is effective at the same time This solves the problem that the PUCCH needs different formats in different locations of the cell.
- the broadcast multicast scheduling information may not be checked.
- the HARQ-ACK information indicated is fed back; or, the HARQ-ACK information is fed back on the PUCCH resource indicated by the broadcast multicast scheduling signaling.
- the terminal when determining the uplink resources corresponding to unicast, may receive unicast scheduling signaling sent by the base station, where the unicast scheduling signaling carries scheduling information of uplink resources; or, the receiving base station passes The periodic uplink resource information configured by high-layer signaling and the uplink resource corresponding to unicast is determined based on the periodic uplink resource information; the periodic uplink resource information includes the transmission period and time slot offset of the uplink resource, and the uplink resource is PUCCH resource or PUSCH resources.
- the uplink resource corresponding to unicast can be determined by means of unicast scheduling signaling or high-level signaling configuration.
- the information elements included in the downlink control information (DCI) in the unicast scheduling signaling are represented as follows: frequency domain resource allocation indication, time domain resource allocation indication, modulation and coding format, redundant coding version, new data indication, HARQ Process ID, PUCCH resource indicator and HARQ feedback time indicator.
- the HARQ-ACK feedback time slot can be calculated through the "time domain resource allocation indication" and the "HARQ feedback time indication" in the above-mentioned control signaling.
- the preset condition also includes: the receiving moment of unicast scheduling signaling is in the broadcast group
- the HARQ-ACK feedback slot indicated by the broadcast scheduling signaling is at least X symbols before and at least X symbols away, and the time slot where the uplink resource is located meets the reception processing time of the service data corresponding to the broadcast multicast scheduling signaling;
- X is the terminal receiving unicast The sum of the processing time of the scheduling signaling and the multiplexing time of the first HARQ-ACK corresponding to the broadcast multicast scheduling signaling. This provides a condition for the terminal to multiplex the first HARQ-ACK codebook corresponding to the broadcast multicast scheduling signaling to the uplink resource corresponding to the unicast.
- the DCI of the broadcast multicast scheduling signaling and the unicast scheduling signaling is added to instruct the terminal to multiplex the first HARQ-ACK codebook corresponding to the broadcast multicast scheduling signaling to the uplink resources of the unicast scheduling.
- the request message includes a first indication field and an identification number of the first HARQ-ACK codebook.
- the first indication field is used to indicate whether the terminal waits for information carried in the unicast scheduling signaling, and a new field is added to the first DCI.
- a request message is added to the newly added field or the original field in the first DCI is newly added to indicate the meaning of the request message;
- the response message includes the second indication field and the identification number of the first HARQ-ACK codebook, and the second The indication field is used to indicate whether to carry the first HARQ-ACK codebook on the uplink resource, where a new field is added to the second DCI and a response message is added to the added field or the original field in the second DCI is added Have the indication meaning to the response message;
- the first indication field and the identification number of the first HARQ-CAK codebook may be added to the first DCI in the broadcast multicast scheduling signaling, and the first indication field may be 1 bit, in which case the bit is 0 indicates that the terminal waits for the information carried in the unicast scheduling signaling, and when the bit is 1, indicates that the terminal does not wait for the information carried in the unicast scheduling signaling.
- the broadcast multicast scheduling signaling carrying the request message may be referred to as specific broadcast multicast scheduling signaling.
- the request message can also be carried in the first DCI by adding an indication meaning to the request message to the original field in the first DCI.
- the 2bit of the "PUCCH power control command” is used to indicate the identification number of the first HARQ-ACK codebook.
- the PUCCH power control command is invalid in broadcast and multicast and can be used as a reserved bit; the above “modulation coding format-5
- the number of bits used for "bit” is reduced by 1 bit, that is, the modulation and coding format becomes 4 bits.
- the saved 1 bit is used to indicate "whether the terminal waits for the information carried in the unicast scheduling signaling", and 5 bits can be saved to 4 bits. The reason is based on the broadcast multicast scheduling situation, which needs to meet the performance requirements of most terminals, so its code rate and modulation order will not be too high.
- the second indication field and the identification number of the first HARQ-CAK codebook can be added to the second DCI in the unicast scheduling signaling.
- the second indication field may be 1 bit. At this time, when this bit is 0, it indicates that the first HARQ-ACK codebook is carried on the uplink resource, and when the bit is 1, it indicates that the first HARQ-ACK codebook is not carried on the uplink resource;
- the identification number of a HARQ-CAK codebook can be 2 bits and is used to distinguish 4 codebooks.
- the unicast scheduling signaling that carries the response message may be referred to as specific unicast scheduling signaling.
- the response message includes a K-bit portability bitmap
- K represents the maximum number of HARQ-ACK codebooks for broadcast and multicast
- -ACK codebook when the value of the bit is the second preset value, it means that the corresponding HARQ-ACK codebook is not carried. That is, it can also indicate whether to carry the corresponding HARQ-ACK codebook of broadcast and multicast by means of a bitmap.
- the above-mentioned explicit indication is used to indicate that the terminal needs to multiplex the first HARQ-ACK codebook of the broadcast and multicast to the uplink resource corresponding to the unicast, so that the terminal can pass through before judging whether the multiplexing preset condition is satisfied.
- the signaling determines whether to perform HARQ-ACK multiplexing, which improves multiplexing efficiency.
- this embodiment before determining whether the preset condition is satisfied, it is also necessary to determine the specific information of the preset window. At this time, this embodiment can obtain the configuration information of the preset window predefined by the protocol; or, receive the configuration information of the preset window sent by the base station through high-level signaling, where the configuration information includes the start of the preset window The reference position (P0), the starting position offset value (offset) and the window length (L) of the preset window.

This value d allows the terminal to complete the reception/analysis and multiplexing of the scheduling signaling.
- the parameter value can be 14 symbols or other values.
- Condition 2 Time Y meets the requirements of the terminal receiving the broadcast/multicast service data delay, that is, the terminal can complete the last broadcast/multicast service data reception and HARQ-ACK multiplexing.
- the above two conditions can also be changed into the following description: if the specific unicast scheduling signaling is received within the first d symbols of the uplink PUCCH resource indicated by the broadcast multicast, or the HARQ- indicated by the specific unicast scheduling signaling
- the ACK feedback resource PUCCH does not meet the receiving processing time of the broadcast/multicast service data, and the terminal does not multiplex the HARQ-ACK of the broadcast/multicast to the uplink resource of the unicast scheduling.
- the specific broadcast multicast scheduling signaling is received in slot n, and the scheduling information indicates that the position of the HARQ-ACK feedback from the broadcast and multicast is in slot n+10; the terminal receives specific unicast in slot n+7 Scheduling signaling, and the time distance between slot n+7 and slot n+10 meets the requirement of d, and the uplink feedback resource indicated by unicast scheduling signaling is on slot n+15, which satisfies the terminal to complete broadcast and multicast service data Minimum time requirement for receiving and HARQ-ACK multiplexing.

- the terminal detects uplink unicast scheduling signaling, and the codebook bitmap indication carried by the signaling indication is 1100, which means that the unicast scheduling carries codebook
- the HARQ-ACK information of codebook 2 and codebook 3 does not carry the HARQ-ACK information of codebook 0 and codebook 1.
- unicast scheduling signaling containing the bitmap may also be referred to as specific unicast scheduling signaling.
- Step 3 If the terminal detects that the preset condition is met, it multiplexes the first HARQ-ACK codebook of the broadcast and multicast to the uplink resource indicated by the unicast scheduling signaling.
- the process of judging whether the preset condition is satisfied is as follows: first obtain the configuration information of the preset window.
