Detailed Description
The inventor notices in the process of invention that:
when the terminal is configured to use the semi-static HARQ-ACK codebook, the UE (User Equipment) first determines a PDSCH position set M corresponding to the same timeslot n for HARQ-ACK feedback on each carrier c according to the HARQ-ACK feedback timing sequence (K1), the semi-static timeslot structure (if configured), and the candidate time domain resource allocation information of the PDSCH (Physical Downlink Shared Channel)A，C. Then according to MA，CAnd mapping the HARQ-ACK of the PDSCH received in the PDSCH position set to the corresponding position in the HARQ-ACK feedback sequence, thereby obtaining the HARQ-ACK codebook transmitted in the time slot n.
Specifically, the UE first determines the number of slots that need to be fed back in a slot on a carrier based on the HARQ feedback timing configured by the higher layer signaling, and then determines the maximum number of PDSCHs that can be transmitted in each slot in the slots. If a semi-static slot structure is configured, candidate PDSCHs that do not satisfy the PDSCH transmission condition need to be removed based on the slot structure. When carrier aggregation exists, the HARQ-ACK codebook on each carrier needs to be determined according to the process, and finally the HARQ-ACK codebooks of different carriers are cascaded according to the carrier sequence to obtain the final HARQ-ACK codebook.
In the NR 15 system, when a PUCCH (Physical Uplink Control Channel) carrying HARQ-ACK overlaps a PUCCH (CSI: Channel state Information; SR: Scheduling Request), UCI (Uplink Control Information) needs to be multiplexed and transmitted. The 5G NR system does not support simultaneous transmission of PUCCH and PUSCH (Physical Uplink Shared Channel), and therefore when PUCCH and PUSCH overlap in time, Uplink control information carried by PUCCH needs to be transferred to PUSCH and data needs to be multiplexed and transmitted.
In the prior art, only one PUCCH carrying HARQ-ACK can be transmitted in one slot, so there is only a case where one PUCCH carrying HARQ-ACK overlaps with PUCCH or PUSCH carrying other UCI. However, in the future, a scheme supporting multiple time-division PUCCHs in one slot to carry HARQ-ACK may appear, for example, in the Rel-16 stage, and there is no specific scheme for how to multiplex the HARQ-ACK codebook carried on the PUCCHs on the PUCCH or PUSCH for transmission when the PUCCHs are overlapped with the PUCCHs or PUSCHs carrying other UCIs. One possible approach is to concatenate multiple feedback codebooks, each of which is independent in the prior art to produce a semi-static codebook, but this results in larger feedback redundancy bits.
Fig. 1 is a schematic diagram of HARQ-ACK feedback, as shown in fig. 1, assuming that the configured K1 set is {2,3,4,5}, the uplink is configured with two sub-slots for HARQ-ACK feedback, and assuming that the downlink PDSCH is also divided based on the uplink sub-slot when determining the semi-static codebook, i.e. the boundary of the downlink sub-slot is aligned with the boundary of the uplink sub-slot, then there is a large overlapping region for the feedback windows corresponding to the PUCCH in the first sub-slot in the slot n +3, e.g. the feedback window corresponding to the PUCCH in the first sub-slot in the slot n +3 includes the second sub-slot in the slot n, the slot n +1 and the first sub-slot in the slot n +2, and the feedback window corresponding to the PUCCH in the second sub-slot in the slot n +3 includes the slot n +1 and the slot n +2, so the overlapping region of the two feedback windows is the first sub-slot in the slot n +1 and the slot n +2, in the PDSCH transmission position in the overlapping region, the base station only indicates that the corresponding HARQ-ACK feedback is fed back in one PUCCH resource, but the PDSCH transmission positions in the overlapping region occupy the corresponding HARQ-ACK feedback bit positions in HARQ-ACK feedback codebooks carried by two PUCCHs, if the two HARQ-ACK codebooks need to be multiplexed for transmission, if each codebook is independently used for generating a semi-static codebook according to the existing mode, two feedback bits corresponding to the PDSCH transmission position in the overlapping region exist, and the redundant one feedback bit belongs to redundant information.
In summary, in the 5G NR, since only one PUCCH carrying HARQ-ACK can be transmitted in one slot in the Rel-15 phase, there is only a case where one PUCCH carrying HARQ-ACK overlaps with PUCCH carrying other UCI or with PUSCH. Taking the Rel-16 stage as an example, a scheme supporting multiple time-division PUCCHs to carry HARQ-ACKs in one slot will occur, when these PUCCHs are overlapped with another PUCCH carrying other UCIs or with one PUSCH, if the HARQ-ACKs carried on these PUCCHs are multiplexed and transmitted on the PUCCH or PUSCH, there is no corresponding multiplexing transmission scheme at present, so when a multiple HARQ-ACK multiplexing transmission is given in the embodiment of the present invention, a determination scheme of a semi-static codebook is used to avoid generating redundant feedback bit information, and ensure the performance of the multiple HARQ-ACK codebook multiplexing transmission.
The following describes embodiments of the present invention with reference to the drawings.
Fig. 2 is a schematic diagram of an implementation flow of a terminal-side HARQ-ACK feedback method, as shown in the figure, the implementation flow may include:
step 201, when multiple HARQ-ACK codebooks are multiplexed for transmission and the HARQ-ACK codebooks are all semi-static codebooks, determining that overlapped parts exist in corresponding PDSCH transmission positions in the multiple HARQ-ACK codebooks;
step 202, generating feedback bits only once for the overlapped part in the HARQ-ACK codebook.
Specifically, when multiple HARQ-ACK codebooks are multiplexed for transmission and the multiple codebooks are all semi-static codebooks, if an overlapped part exists in the corresponding PDSCH transmission positions in the multiple HARQ-ACK codebooks, HARQ-ACK feedback information is only generated once for the overlapped part.
In implementation, if there is an overlapping portion in corresponding PDSCH transmission positions in a plurality of HARQ-ACK codebooks, generating feedback bits only once for the overlapping portion in the HARQ-ACK codebooks may include at least the following two ways, which are separately described below.
The first method is as follows:
generating feedback bits only once for an overlapped part in the HARQ-ACK codebook may include:
and determining a PDSCH position set corresponding to the HARQ-ACK codebooks based on the configured HARQ-ACK feedback time sequence K1 and the time slots or the sub-time slots of the HARQ-ACK codebooks, and determining HARQ-ACK feedback information according to the PDSCH position set corresponding to the HARQ-ACK codebooks.
Specifically, a PDSCH position set corresponding to a plurality of HARQ-ACK codebooks is determined based on a configured HARQ-ACK feedback time sequence (K1) and the time slots/sub-time slots where the plurality of HARQ-ACK codebooks are located, and HARQ-ACK feedback information is determined according to the PDSCH position set corresponding to the plurality of HARQ-ACK codebooks.
In a specific implementation, the determining, based on the configured HARQ-ACK feedback timing K1 and the slot or sub-slot in which the multiple HARQ-ACK codebooks are located, a PDSCH position set corresponding to the multiple HARQ-ACK codebooks may include:
after determining a time slot or sub-time slot set corresponding to each HARQ-ACK codebook on a carrier based on the configured HARQ feedback time sequence, combining the time slot or sub-time slot sets corresponding to a plurality of HARQ-ACK codebooks, and removing repeated time slots or sub-time slots to obtain a combined time slot or sub-time slot set;
determining the maximum number of PDSCHs which can be transmitted in each time slot or sub-time slot in the set based on the combined time slot or sub-time slot set;
and under the configuration of the semi-static time slot structure, removing the candidate PDSCH which does not meet the PDSCH transmission condition based on the time slot structure to obtain a PDSCH position set corresponding to a plurality of HARQ-ACK codebooks.
Specifically, firstly, determining a time slot/sub-time slot set corresponding to each HARQ-ACK codebook on a carrier based on a configured HARQ feedback time sequence, then combining the time slot/sub-time slot sets corresponding to a plurality of HARQ-ACK codebooks, and removing repeated time slots/sub-time slots in the combined time slot/sub-time slot sets to obtain a combined time slot/sub-time slot set;
the maximum number of PDSCHs that can be transmitted in each slot/sub-slot is then determined based on the combined set of slots/sub-slots. If a semi-static time slot structure is configured, the candidate PDSCH which does not meet the PDSCH transmission condition is required to be removed based on the time slot structure, and a PDSCH position set corresponding to a plurality of HARQ-ACK codebooks is obtained.
The second method comprises the following steps:
generating HARQ-ACK feedback information only once for the overlapping part may include:
after a PDSCH position set corresponding to each HARQ-ACK codebook is determined based on a configured HARQ-ACK feedback time sequence K1 and a time slot or a sub-time slot where the HARQ-ACK codebooks are located, the PDSCH position sets corresponding to the HARQ-ACK codebooks are combined, repeated PDSCH positions in the PDSCH position sets are removed, PDSCH position sets corresponding to the HARQ-ACK codebooks are obtained, and HARQ-ACK feedback information is determined according to the PDSCH position sets corresponding to the HARQ-ACK codebooks.
Specifically, a PDSCH position set corresponding to each HARQ-ACK codebook is determined based on a configured HARQ-ACK feedback time sequence (K1) and a time slot/sub-time slot where the HARQ-ACK codebook is located, then PDSCH position sets corresponding to a plurality of HARQ-ACK codebooks are combined, repeated PDSCH positions in the PDSCH position sets are removed, PDSCH position sets corresponding to the HARQ-ACK codebooks are obtained, and HARQ-ACK feedback information is determined according to the PDSCH position sets corresponding to the HARQ-ACK codebooks.
Correspondingly, the embodiment of the invention also provides a scheme for receiving the HARQ-ACK feedback, and the following description is provided.

step 301, when multiple HARQ-ACK codebooks are multiplexed for transmission and the HARQ-ACK codebooks are all semi-static codebooks, determining that overlapped parts exist in corresponding PDSCH transmission positions in the multiple HARQ-ACK codebooks;
step 302, receiving HARQ-ACK feedback information, wherein the HARQ-ACK feedback information is HARQ-ACK feedback information of the UE which generates feedback bits only once for the overlapping part.
In an implementation, receiving HARQ-ACK feedback information, where the HARQ-ACK feedback information is HARQ-ACK feedback information in which the UE generates feedback bits only once for the overlap portion, may include:
the first method is as follows:

The following is a description of the two embodiments by way of example.
Embodiment mode 1:
fig. 4 is a schematic diagram of HARQ-ACK feedback in embodiment mode 1, as shown in the figure, it is assumed that a terminal is configured with one carrier for transmitting URLLC (Ultra Reliable and Ultra Low delay) service, uses a subcarrier interval of 15kHz for transmission, is configured with two sub-slots in one slot for HARQ-ACK feedback, and configures HARQ feedback using a semi-static codebook for high-level signaling, and a HARQ timing set K1 includes {2,3,4,5 }.
As shown in fig. 4, in slot 3, PUCCH resources corresponding to HARQ-ACKs in two sub-slots overlap with one SR resource, and assuming that the two HARQ-ACKs and SRs need to be multiplexed on one PUCCH resource for transmission, the terminal determines the HARQ-ACK feedback codebook for multiplexed transmission based on the following ways:
the terminal determines, based on the K1 set {2,3,4,5}, that the downlink sub-slot corresponding to the first sub-slot in slot 3 is the second sub-slot in slot 0, two sub-slots in slot 1, and the first sub-slot in slot 2. The downlink transmission sub-time slot corresponding to the second sub-time slot in the time slot 3 is four sub-time slots in the time slot 1 and the time slot 2.
Therefore, the downlink transmission sub-slot sets corresponding to the two sub-slots in the slot 3 are sub-slots {1,2,3,4,2,3,4,5}, and then repeated sub-slots are removed to obtain a combined sub-slot set {1,2,3,4,5}, and based on the combined slot/sub-slot set, the terminal can determine the maximum number of PDSCHs that can be transmitted in each sub-slot.
Assuming that the time slots 0/1/2 are all downlink time slots, and 1 PDSCH is transmitted in each sub-time slot at maximum, it can be obtained that the PDSCH transmission position set includes 5 PDSCH transmission positions, and if the PDSCH transmissions scheduled by the base station in sub-time slot 3 and sub-time slot 4 are correctly received by the terminal, the terminal multiplexes the HARQ-ACK feedback codebook 00110 for transmission.
Embodiment mode 2:
fig. 5 is a schematic diagram of HARQ-ACK feedback in embodiment 2, and as shown in fig. 5, PUCCH resources corresponding to HARQ-ACKs in two sub-slots in slot 3 are overlapped with one PUSCH, assuming that the two HARQ-ACKs need to be multiplexed on a PUSCH resource for transmission, and using a joint coding method, the terminal determines a HARQ-ACK feedback codebook for multiplexed transmission based on the following methods:
the terminal determines, based on the K1 set {2,3,4,5}, that the downlink transmission sub-slot corresponding to the first sub-slot in slot 3 is the second sub-slot in slot 0, two sub-slots in slot 1, and the first sub-slot in slot 2, so that the corresponding PDSCH transmission location set is PDSCH transmission location {1,2,3,4,5,6,7 }.
The downlink transmission sub-slot corresponding to the second sub-slot in slot 3 is four sub-slots in slot 1 and slot 2, and therefore the corresponding PDSCH transmission position set is PDSCH transmission position {3,4,5,6,7,8 }.
Therefore, the PDSCH transmission position sets corresponding to two sub-slots in slot 3 are combined to obtain PDSCH transmission positions {1,2,3,4,5,6,7,3,4,5,6,7,8}, and then repeated PDSCH transmission positions in the PDSCH transmission positions are removed to obtain a combined PDSCH transmission position set {1,2,3,4,5,6,7,8 }. The combined PDSCH transmission location set contains 8 PDSCH transmission locations, and if the base station schedules PDSCH transmissions in PDSCH transmission location 3/4/6/7/8, the terminal multiplexes the HARQ-ACK feedback codebook 00110111 for transmissions when the terminal correctly receives the PDSCH transmissions.
