Description

Feedback codebook, method, device, equipment and medium for determining feedback information

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, a device, and a medium for determining a feedback codebook and feedback information.

Background

In NR (New Radio, new air interface), the HARQ (Hybrid Automatic Repeat reQuest) feedback timing value indicates a number of slot offsets of a PUCCH (Physical Uplink Control Channel) carrying HARQ-ACK (Hybrid Automatic Repeat reQuest acknowledgement) feedback, or a PDCCH (Physical Downlink Control Channel) indicating a release of an SPS (Semi-persistent scheduling) PDSCH (Physical Downlink Shared Channel). A DCI (Downlink Control Information) format 1 _0includes a HARQ feedback timing indication Information field of 3 bits, which is mapped to one value of a predetermined HARQ feedback timing value set {1,2,3,4,5,6,7,8 }. DCI format 1 \u1 may include a 0, 1,2, or 3-bit HARQ feedback timing indication information field, where the specific bit number depends on the number of elements in the HARQ feedback timing value set configured by the higher layer signaling, and the HARQ feedback timing value indicated by DCI format 1 _1is mapped to one of a group of HARQ feedback timing value sets configured by the higher layer signaling.

At present, in an NR communication system, a scheme of using a semi-static codebook and a dynamic codebook for HARQ-ACK feedback is supported.

When a terminal is configured to use a semi-static HARQ-ACK codebook, a UE (User Equipment) first determines a PDSCH position set M corresponding to a same time slot n for HARQ-ACK feedback on each carrier c according to a HARQ-ACK feedback timing sequence (K1), a semi-static time slot structure (if configured), and PDSCH candidate time domain resource allocation information. And then according to the set M, 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.

When cross-carrier scheduling between different SCS (Subcarrier Spacing) carriers is supported and the SCS of a PDCCH carrier is smaller than the SCS on a PDSCH carrier, it is possible to support one PDCCH maximally scheduled PDSCH carrier

PDSCH transmission in one slot. In order to save uplink resources, it may be supported that all PDSCHs scheduled by the PDSCH are fed back on the same PUCCH, and the existing semi-static codebook determination method cannot include feedback information of all PDSCHs scheduled by the PDCCH. For example, as shown in fig. 1, SCS on PDCCH carrier 1 is 15khz and SCS on PDSCH carrier 2 is 30kHz, then one PDCCH on carrier 1 can schedule 2 PDSCH transmissions on carrier 2 at maximum. Assuming that the SCS of PUCCH carrier 3 is also 30kHz, the base station configures 1K 1 values to the terminal as 1, the PDCCH in slot n on carrier 1 schedules two PDSCH transmissions in slot 2n on carrier 2 and slot 2n +1 and indicates feedback in slot 2n +2 in carrier 3, based on the existing semi-static codebook determination mode, in the HARQ-ACK codebook carried by PUCCH transmitted in slot 2n +2 on carrier 3, for carrier 2, PDSCH feedback information in slot 2n +1 can only be contained, and slot 2 cannot be containedPDSCH feedback information in n, resulting in partial PDSCH not getting feedback information.

In summary, in the conventional semi-static codebook determining method, under the condition of multi-slot scheduling, part of PDSCH transmission cannot obtain effective feedback information, so that unnecessary retransmission is caused to the base station, and the transmission efficiency is reduced.

Detailed Description

In view of the situation that in the prior art, under the condition of multi-slot scheduling and/or multi-carrier scheduling, part of PDSCH transmission cannot obtain effective feedback information, thereby causing unnecessary retransmission of the base station, embodiments of the present invention provide a scheme for determining a feedback codebook and feedback information, so as to enable all PDSCHs to obtain effective feedback and improve data transmission efficiency under the condition of multi-slot scheduling and/or multi-carrier scheduling.

In the embodiment of the invention, for the condition of configuring multi-slot scheduling or multi-carrier scheduling, based on the maximum number of time slots of the multi-slot scheduling or the condition that SCS of scheduling carriers and scheduled carriers are different during the multi-carrier scheduling, a feedback time sequence set (K1 set) pre-configured by a base station is converted into a new feedback time sequence set (K1' set), or a semi-static HARQ-ACK feedback codebook is determined according to the SCS of the carrier where a PDCCH is positioned or the carrier time slot with the minimum SCS in the multi-carrier scheduling.

In one possible implementation, a semi-static HARQ-ACK feedback codebook is determined from a PDCCH slot.

It should be noted that this method is applicable to the case where one PDCCH on a carrier with a smaller SCS schedules multiple slots on a carrier with a larger SCS during cross-carrier scheduling of different SCS, and the starting positions of the multiple slots and the intervals of the slots where the PDCCH is located are fixed.

In specific implementation, generating a semi-static HARQ-ACK feedback codebook according to a PDCCH slot includes: for a time slot N where a semi-static HARQ-ACK feedback codebook is transmitted, finding a corresponding uplink time slot N-K based on each K value in a K1 set, then finding all PDCCH time slots overlapped with the uplink time slot N-K, and then determining the semi-static HARQ-ACK feedback codebook by taking N PDSCH transmission time slots corresponding to all the PDCCH time slots as time slots where PDSCH transmission positions corresponding to the semi-static HARQ-ACK feedback codebook are located;

the N PDSCH transmission time slots corresponding to the PDCCH time slot are time slots in which the maximum N PDSCH transmissions that can be scheduled by the PDCCH in one PDCCH time slot are located during multi-time slot scheduling, and N is a predetermined value or a value configured by a higher layer, for example, when the maximum number of time slots scheduled by one PDCCH is 2, N =2.

In one possible implementation, the semi-static HARQ-ACK feedback codebook is determined according to the carrier slot with the smallest SCS in the multi-carrier scheduling.

It should be noted that this method is applicable to a case where one PDCCH transmitted on one carrier schedules multiple carriers, and the starting positions of the scheduled time slots on multiple scheduled carriers and the intervals of the time slots where the PDCCH is located are fixed, and SCS of the multiple scheduled carriers may be the same or different.

In specific implementation, the generating the semi-static HARQ-ACK feedback codebook based on the PDCCH carrier or based on the carrier timeslot with the smallest SCS in a plurality of carrier schedules includes: and for the time slot n where the semi-static HARQ-ACK feedback codebook is transmitted, based on each K value in the K1 set, finding a corresponding uplink time slot n-K, then finding all PDCCH carriers overlapped with the uplink time slot n-K or the carrier time slot with the minimum SCS in multi-carrier scheduling, and then taking the PDSCH transmission time slot corresponding to the carrier time slot with the minimum SCS in the PDCCH carriers or the multi-carrier scheduling on all scheduled carriers as the time slot where the PDSCH transmission position corresponding to the semi-static HARQ-ACK feedback codebook is located to determine the semi-static HARQ-ACK feedback codebook.

The PDCCH carrier or the PDSCH transmission time slot corresponding to the carrier time slot with the minimum SCS in the multi-carrier scheduling on all the scheduled carriers is the time slot of the PDSCH transmission which can be scheduled on all the scheduled carriers by the PDCCH in one PDCCH carrier in the multi-carrier scheduling.

In a possible implementation manner, a K1 set configured by a base station is converted into a new K1 'set according to the maximum number of timeslots scheduled by multiple timeslots, and then a semi-static HARQ-ACK feedback codebook is generated according to the new K1' set.

It should be noted that this method is applicable to the case where one PDCCH schedules multiple slots and the starting positions of the multiple slots and the intervals of the slots where the PDCCH is located are not fixed, and is applicable to multi-slot scheduling in the same SCS or different SCS.

In specific implementation, the K1 set configured by the base station is converted into a new K1' set according to the maximum number of timeslots scheduled by multiple timeslots, which includes the following three cases:

case 1: SCS of a PDSCH carrier and a PUCCH carrier is the same, a feedback time sequence set { K1, K1+1, \ 8230;, K1+ N-1} is obtained according to a configured K1 set and the maximum time slot number N scheduled by a PDCCH, and then a new K1' set is obtained by deleting an overlapped value;

case 2: SCS of PDSCH carrier is larger than SCS of PUCCH carrier, and feedback time sequence set is obtained according to configured K1 set and maximum time slot number N scheduled by one PDCCH

Then deleting the overlapped value to obtain a new K1' set;

case 3: SCS of PDSCH carrier is smaller than that of PUCCH carrier, and feedback time sequence set { K1, K1+1, \ 8230, K1+ (N.2) } is obtained according to configured K1 set and maximum time slot number N scheduled by one PDCCH ^{μPUCCH-μPDSCH} -1) and then deleting the values overlapping therein to obtain a new K1' set.

The following describes the method for determining a feedback codebook according to an embodiment of the present invention in detail with reference to the accompanying drawings.

Example one

As shown in fig. 2, SCS on PDCCH carrier 1 is 15khz and SCS on pdsch carrier 2 is 30kHz. When the configured carrier 2 uses the carrier 1 for multi-slot scheduling, 2 PDSCH transmissions on one PDCCH on the carrier 1 can be scheduled maximally on the carrier 2. Assuming that the SCS of PUCCH carrier 3 is also 30kHz, the base station configures 1K 1 value to the terminal as 1, one PDCCH in slot n on carrier 1 schedules PDSCH transmission in slot n on carrier 1 and indicates feedback in slot 2n +2 in carrier 3, and the other PDCCH schedules two PDSCH transmissions in slot 2n on carrier 2 and slot 2n +1 and indicates feedback in slot 2n +2 in carrier 3.

For the PUCCH in timeslot 2n +2 on carrier 3, based on the configuration of the K1 set, a carrier is found, the uplink timeslot corresponding to 3 is 2n +1, and since PDCCH timeslots corresponding to carrier 1 and carrier 2 are both timeslots on carrier 1, a PDSCH transmission timeslot corresponding to the semi-static HARQ-ACK feedback codebook of timeslot 2n +2 in carrier 3 is determined to be timeslot n of carrier 1 and timeslot 2n and timeslot 2n +1 of carrier 2 based on timeslot n of carrier 1.

Assuming that each time slot has only one PDSCH transmission position and does not collide with TDD uplink and downlink configuration, and the transmission is in a single codeword transmission mode and is not applicable to CBG-based transmission, the semi-static HARQ-ACK feedback codebook in time slot 2n +2 on carrier 3 contains 3 bits of feedback information, the first bit corresponds to PDSCH transmission in time slot n on carrier 1, the second bit corresponds to PDSCH transmission in time slot 2n on carrier 2, and the third bit corresponds to PDSCH transmission in time slot 2n +1 on carrier 2.

It should be noted that, in this embodiment, the configured carrier 2 uses the carrier 1 to perform multi-slot scheduling, which represents that PDSCH transmission in 2 slots on the PDCCH transmitted on the carrier 1 is schedulable to the carrier 2 at maximum, but PDSCH transmission in 2 slots is not necessarily scheduled, and only 1 PDSCH transmission may be scheduled, for example, only PDSCH transmission in slot 2n or slot 2n +1 on 2 is scheduled, and at this time, the determination manner of the semi-static HARQ-ACK feedback codebook is the same as that described above.

Example two

As shown in fig. 3, SCS on PDCCH carrier 1 is 15khz and SCS on PDSCH carrier 2 is 30kHz, the PDCCH on configured carrier 1 can be multi-carrier scheduled while PDSCH transmission on carrier 1 and carrier 2 is scheduled. Assuming that the SCS of PUCCH carrier 3 is also 30kHz, the base station configures 1K 1 values to the terminal as 1, and one PDCCH in slot n on carrier 1 schedules PDSCH transmission in carrier 1 slot n and carrier 2 slot 2n and indicates feedback in slot 2n +2 in carrier 3.

For the PUCCH in time slot 2n +2 on carrier 3, based on the configuration of the K1 set, finding that the uplink time slot corresponding to carrier 3 is 2n +1, and because the carrier that can be scheduled is carrier 1 and carrier 2 during multi-carrier scheduling, and the carrier with the minimum SCS is carrier 1, determining the PDSCH transmission time slot corresponding to the semi-static HARQ-ACK feedback codebook of time slot 2n +2 in carrier 3 as time slot n of carrier 1 and time slot 2n and time slot 2n +1 of carrier 2 based on time slot n of carrier 1. Assuming that there is only one PDSCH transmission position in each time slot and does not collide with TDD uplink and downlink configurations, the transmission is in a single codeword transmission mode and is not applicable to CBG-based transmission, the semi-static HARQ-ACK feedback codebook in time slot 2n +2 on carrier 3 contains 3 bits of feedback information, the first bit corresponds to PDSCH transmission in time slot n on carrier 1, the second bit corresponds to PDSCH transmission in time slot 2n on carrier 2, and the third bit corresponds to PDSCH transmission in time slot 2n +1 on carrier 2.

It should be noted that, in the embodiment, configured to use multi-carrier scheduling, when SCS of multiple carriers is different, a PDCCH of one multi-carrier scheduling may support scheduling only 1 slot on a carrier with a larger SCS, or may schedule multiple slots at the same time, in either case, the determination method of the semi-static HARQ-ACK feedback codebook is the same as the above process.
