This application requires the priority of a Chinese patent application filed with the Chinese Patent Office on April 29, 2020, the application number is 202010355891.8, and the application title is "a feedback codebook, feedback information determination method, device, equipment, and medium". The entire content is incorporated into this application by reference.

Technical field

This application relates to the field of communication technology, and in particular to a method, device, device, and medium for determining feedback codebook and feedback information.

Background technique

In NR (New Radio), HARQ (Hybrid Automatic Repeat reQuest) feedback timing value represents the PUCCH that carries HARQ-ACK (Hybrid Automatic Repeat reQuest-ACKnowledge) feedback (Physical Uplink Control CHannel, physical uplink control channel) relative to the PDSCH (Physical Downlink Shared CHannel, physical downlink shared channel) ending time slot number of time slot offset, or relative indication SPS (Semi-Persistent Scheduling, Semi-persistent scheduling) The number of time slot offsets of the ending time slot of the PDCCH (Physical Downlink Control CHannel) released by the PDSCH. DCI (Downlink Control Information) format 1_0 contains a 3-bit HARQ feedback timing indication information field, which is mapped to a predetermined set of HARQ feedback timing values {1, 2, 3, 4, 5, 6, 7, 8} A value in. DCI format 1_1 may contain 0, 1, 2 or 3-bit HARQ feedback timing indication information field. The specific number of bits depends on the number of elements in the HARQ feedback timing value set configured by higher layer signaling. The HARQ indicated in DCI format 1_1 The feedback timing value is mapped to one of a set of HARQ feedback timing value sets configured by higher layer signaling.

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

When the terminal is configured to use the semi-static HARQ-ACK codebook, the UE (User Equipment) first reports according to the HARQ-ACK timing (K1), the semi-static time slot structure (if configured) and the PDSCH candidate time domain resources The allocation information determines the PDSCH position set M corresponding to the HARQ-ACK feedback in the same time slot n on each carrier c. Then, according to the set M, the HARQ-ACK of the PDSCH received in the PDSCH position set is mapped 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 time slots that need to be fed back in a time slot on the carrier based on the HARQ feedback timing configured by high-level signaling, and then determines the maximum PDSCH that can be transmitted in each time slot in these time slots Number. If a semi-static time slot structure is configured, the candidate PDSCH that does not meet the PDSCH transmission conditions needs to be removed based on the time slot structure. When there is carrier aggregation, the HARQ-ACK codebook on each carrier needs to be determined according to the above process respectively, and finally the HARQ-ACK codebooks of different carriers are concatenated according to the carrier order to obtain the final HARQ-ACK codebook.

When it supports cross-carrier scheduling between different SCS (SubCarrier Spacing) carriers, and the SCS of the PDCCH carrier is smaller than the SCS on the PDSCH carrier, it may support a PDCCH maximum scheduling of the PDSCH carrier

PDSCH transmission in time slots. In order to save uplink resources, it may be supported that all PDSCHs scheduled by this PDCCH are fed back on the same PUCCH, and the existing semi-static codebook determination method cannot include feedback information of all PDSCHs scheduled by this PDCCH. For example, as shown in Fig. 1, the SCS on PDCCH carrier 1 is 15 kHz, and the SCS on PDSCH carrier 2 is 30 kHz, then one PDCCH on carrier 1 can schedule up to 2 PDSCH transmissions on carrier 2. Assuming that the SCS of PUCCH carrier 3 is also 30kHz, the base station configures a K1 value of 1 for the terminal, and the PDCCH in time slot n on carrier 1 schedules two PDSCHs in time slot 2n and time slot 2n+1 on carrier 2. Transmission, and the indication is fed back in time slot 2n+2 in carrier 3, based on the existing semi-static codebook determination method, in the HARQ-ACK codebook carried by PUCCH transmitted in time slot 2n+2 of carrier 3, For the carrier 2 can only contain the PDSCH feedback information in the time slot 2n+1, and cannot contain the PDSCH feedback information in the time slot 2n, resulting in partial PDSCH unable to obtain feedback information.

To sum up, in the existing semi-static codebook determination method, in the case of multi-slot scheduling, some PDSCH transmissions cannot obtain effective feedback information, which causes unnecessary retransmissions of the base station and reduces transmission efficiency.

Detailed ways

In view of the fact that in the prior art, in the case of multi-slot scheduling and/or multi-carrier scheduling, some PDSCH transmissions cannot obtain effective feedback information, thereby causing unnecessary retransmissions by the base station, an embodiment of the present application provides a feedback code This feedback information determination scheme is used to enable effective feedback of all PDSCHs in the case of multi-slot scheduling and/or multi-carrier scheduling, thereby improving data transmission efficiency.

In the embodiment of this application, when multi-slot scheduling or multi-carrier scheduling is configured, based on the maximum number of time slots for multi-slot scheduling, or when the SCS of the scheduled carrier and the scheduled carrier are different during multi-carrier scheduling, the base station is set in advance The configured feedback timing set, namely the K1 set, is converted to the new feedback timing set, namely the K1′ set, or the semi-static HARQ-ACK feedback codebook is determined according to the SCS of the carrier where the PDCCH is located, or the smallest carrier time slot of the SCS in the multi-carrier scheduling .

In a possible implementation manner, the semi-static HARQ-ACK feedback codebook is determined according to the PDCCH time slot.

It should be noted that this method is suitable for cross-carrier scheduling of different SCSs. A PDCCH on a carrier with a smaller SCS schedules multiple timeslots on a larger SCS carrier, and the start positions of the multiple timeslots and the time when the PDCCH is located When the gap is fixed.

During specific implementation, generating the semi-static HARQ-ACK feedback codebook according to the PDCCH time slot includes: for the time slot n where the semi-static HARQ-ACK feedback codebook is transmitted, based on each k value in the K1 set, find the corresponding Uplink time slot nk, and then find all PDCCH time slots that overlap with uplink time slot nk, and then use all the N PDSCH transmission time slots corresponding to the above PDCCH time slots as the PDSCH transmission position corresponding to the semi-static HARQ-ACK feedback codebook The time slot in which it is located to determine the semi-static HARQ-ACK feedback codebook;

Among them, the N PDSCH transmission time slots corresponding to the above PDCCH time slot are the time slots where the maximum N PDSCH transmissions can be scheduled by the PDCCH in a PDCCH time slot in multi-slot scheduling, and N is a predetermined value or configured by a higher layer For example, when the maximum number of time slots scheduled by one PDCCH is 2, N=2.

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

It should be noted that this method is applicable to the situation where one PDCCH transmitted on one carrier schedules multiple carriers, and the start position of the scheduled time slot on multiple scheduled carriers and the interval between the time slots where the PDCCH is located are fixed, and multiple The SCS of the scheduled carrier may be the same or different.

In specific implementation, generating a semi-static HARQ-ACK feedback codebook based on the PDCCH carrier or based on multiple carrier-scheduled carrier time slots with the smallest SCS, including: for the time slot n where the semi-static HARQ-ACK feedback codebook is transmitted , Based on each value of k in the K1 set, find the corresponding uplink time slot nk, and then find all the PDCCH carriers that overlap with the uplink time slot nk or the carrier time slot with the smallest SCS in the multi-carrier scheduling, and then add the above-mentioned PDCCH carrier or more In carrier scheduling, the PDSCH transmission time slot corresponding to the smallest SCS carrier time slot on all scheduled carriers is used as the time slot of the PDSCH transmission position corresponding to the semi-static HARQ-ACK feedback codebook to determine the semi-static HARQ-ACK feedback Codebook.

Among them, the above-mentioned PDCCH carrier or the carrier time slot with the smallest SCS in multi-carrier scheduling corresponds to the PDSCH transmission time slot on all scheduled carriers. In multi-carrier scheduling, the maximum PDSCH transmission that can be scheduled for the PDCCH in a PDCCH carrier is in all scheduled carriers. Scheduling time slots on the carrier.

In a possible implementation manner, the K1 set configured by the base station is converted into a new K1' set according to the maximum number of timeslots for multi-slot scheduling, 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 suitable for the case where one PDCCH schedules multiple time slots and the start positions of the multiple time slots and the interval between the time slots where the PDCCH is located are not fixed. For the same SCS or different SCSs, the multi-slot scheduling is both Be applicable.

During specific implementation, the K1 set configured by the base station is converted to a new K1′ set according to the maximum number of time slots for multi-slot scheduling, including the following three situations:

Case 1: The SCS of the PDSCH carrier and the PUCCH carrier are the same. According to the configured K1 set and the maximum number of time slots N scheduled by a PDCCH, the feedback timing set {K1, K1+1,..., K1+N-1} is obtained, and then Delete the overlapping values to obtain a new K1' set;

Case 2: The SCS of the PDSCH carrier is greater than the SCS of the PUCCH carrier, and the feedback timing set is obtained according to the configured K1 set and the maximum number of time slots N scheduled by a PDCCH

Then delete the overlapping values to get a new K1'set;

Case 3: The SCS of the PDSCH carrier is smaller than the SCS of the PUCCH carrier. According to the configured K1 set and the maximum number of time slots N scheduled by a PDCCH, the feedback timing set {K1, K1+1,..., K1+(N·2 ^μPUCCH- μPDSCH -1)}, and then delete the overlapping values to ^{obtain a new K1' set.}

The method for determining the feedback codebook provided in the embodiments of the present application will be described in detail below with specific embodiments in conjunction with the accompanying drawings.

Example one

As shown in Figure 2, the SCS on PDCCH carrier 1 is 15 kHz, and the SCS on PDSCH carrier 2 is 30 kHz. If the configured carrier 2 uses carrier 1 for multi-slot scheduling, one PDCCH on carrier 1 can schedule up to 2 PDSCH transmissions on carrier 2. Assuming that the SCS of PUCCH carrier 3 is also 30kHz, the base station configures a K1 value of 1 for the terminal, and a PDCCH in time slot n on carrier 1 schedules the PDSCH transmission in time slot n of carrier 1 and indicates the transmission of PDSCH in carrier 3 Feedback in time slot 2n+2, another PDCCH schedules two PDSCH transmissions in time slot 2n and time slot 2n+1 on carrier 2 and indicates feedback in time 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, the uplink time slot corresponding to carrier 3 is found to be 2n+1, because the PDCCH time slots corresponding to carrier 1 and carrier 2 are all on carrier 1. Time slot, the semi-static HARQ-ACK feedback codebook corresponding to the PDSCH transmission time slot corresponding to the time slot 2n+2 in the carrier 3 is determined based on the time slot n of the carrier 1 as the time slot n of the carrier 1 and the time slot 2n of the carrier 2. And time slot 2n+1.

Assuming that there is only one PDSCH transmission position in each time slot and does not conflict with the TDD (Time Division Duplexing) uplink and downlink configuration, the transmission is a single codeword transmission mode and does not apply based on CBG (Code Block Group, code block group) ) 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 the PDSCH transmission in time slot n on carrier 1, and the second The bit corresponds to the PDSCH transmission in time slot 2n on carrier 2, and the third bit corresponds to the PDSCH transmission in time slot 2n+1 on carrier 2.

It should be noted that, in this embodiment, carrier 2 is configured to use carrier 1 for multi-slot scheduling, which means that the PDCCH transmitted on carrier 1 can schedule PDSCH transmission in 2 time slots on carrier 2, but it is not necessary. Scheduling PDSCH transmission in 2 time slots, or scheduling only 1 PDSCH transmission, for example, only scheduling PDSCH transmission in time slot 2n or time slot 2n+1 on 2, then the semi-static HARQ-ACK feedback codebook The determination method is the same as above.

Example two

As shown in Figure 3, the SCS on PDCCH carrier 1 is 15 kHz, and the SCS on PDSCH carrier 2 is 30 kHz. The PDCCH on carrier 1 is configured for multi-carrier scheduling, and PDSCH transmission on carrier 1 and carrier 2 are scheduled at the same time. Assuming that the SCS of PUCCH carrier 3 is also 30kHz, the base station configures a K1 value of 1 for the terminal, a PDCCH in time slot n on carrier 1 schedules PDSCH transmission in time slot n of carrier 1 and time slot 2n of carrier 2 and The indication is fed back in time 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, the uplink time slot corresponding to carrier 3 is found to be 2n+1. Because of multi-carrier scheduling, the carriers that can be scheduled are carrier 1 and carrier 2. The carrier with the smallest SCS is carrier 1, so the semi-static HARQ-ACK feedback codebook corresponding to the time slot 2n+2 in carrier 3 is determined based on the time slot n of carrier 1, and the PDSCH transmission time slot corresponding to carrier 1 time slot n and Carrier 2 time slot 2n and time slot 2n+1. Assuming that there is only one PDSCH transmission position in each time slot and does not conflict with the TDD uplink and downlink configuration, the transmission is a single codeword transmission mode and CBG-based transmission is not applied, then the semi-static HARQ in time slot 2n+2 on carrier 3 -ACK feedback codebook 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 the PDSCH transmission in time slot 2n+1 on carrier 2.

It should be noted that, in this embodiment, it is configured to use multi-carrier scheduling. When the SCS of multiple carriers is different, a multi-carrier scheduled PDCCH may only support scheduling one time slot on a carrier with a larger SCS. Multiple time slots may be scheduled 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.

Scenario b: The base station configures the terminal with two K1 values {1, 2}, and the maximum number of time slots scheduled by a PDCCH is N=2. Since the SCS of the PDSCH carrier and the PUCCH carrier are the same, according to the configured K1 set and one The maximum number of time slots scheduled by PDCCH is N, and the feedback timing set {K1, K1+1,..., K1+N-1} is {1, 2, 2, 3}, and the new K1′ is obtained after deleting the repeated values Set {1, 2, 3}, and then determine the semi-static HARQ-ACK feedback codebook in slot n+2 based on this new K1' set;

Scenario c: The base station configures the terminal with two K1 values {1, 2}, and the maximum number of time slots scheduled by a PDCCH is N=4. Since the SCS of the PDSCH carrier and the PUCCH carrier are the same, according to the configured K1 set and one PDCCH The maximum number of time slots scheduled is N, and the feedback timing set {K1, K1+1,..., K1+N-1} is {1, 2, 3, 4, 2, 3, 4, 5}, and then delete it The overlapping values obtain a new K1' set {1, 2, 3, 4, 5}, and then based on this new K1' set to determine the semi-static HARQ-ACK feedback codebook in time slot n+2.

Scenario b: The base station configures the terminal with two K1 values {1, 2}, and the maximum number of time slots scheduled by a PDCCH is N=2. Since the SCS of the PDSCH carrier is greater than the SCS of the PUCCH carrier, according to the configured K1 set and The maximum number of timeslots scheduled by a PDCCH is N, and the feedback timing set is obtained

It is {1, 2, 2, 3}, after deleting the repeated values, a new K1' set {1, 2, 3} is obtained, and then based on this new K1' set to determine the semi-static HARQ in time slot n+2 -ACK feedback codebook.

Scenario c: The base station configures the terminal with two K1 values {1, 2}, and the maximum number of time slots scheduled by a PDCCH is N=4.
