Description

Codebook transmission method and device

The present application claims priority from chinese patent application filed on 13/02/2020, having application number 202010091815.0 and entitled "codebook transmission method and apparatus", the entire contents of which are incorporated herein by reference.

Technical Field

The present application relates to the field of communications technologies, and in particular, to a codebook transmission method and apparatus.

Background

Hybrid automatic repeat acknowledgement (HARQ-ACK) feedback is currently supported in new air interface (NR) communication systems using semi-static codebook and dynamic codebook schemes.

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

And when the terminal is configured to use the dynamic HARQ-ACK codebook, determining the bit sequence and the Total bit number of the feedback based on the counting DAI (Counter DAI, C-DAI) and the Total DAI (Total DAI, T-DAI) indicated by the downlink DCI. And the terminal determines a PDCCH detection position set according to the pre-configured HARQ-ACK feedback time sequence candidate set and the scheduling time sequence candidate set, and assumes that the C-DAI and the T-DAI in the DCI are set based on the PDCCH detection position set. And the C-DAI indicates a PDCCH index which is transmitted to the current PDCCH detection position on the current carrier and used for scheduling the PDSCH or indicating the SPS PDSCH release according to the sequence of a frequency domain and a time domain. The T-DAI indicates the total number of PDCCHs transmitted to the current PDCCH detection location set for scheduling PDSCH or for indicating SPS PDSCH release. The T-DAIs in the same PDCCH detection position on multiple carriers are the same. And if any carrier is configured to use data transmission based on CBG, generating two sub-codebooks, wherein the first sub-codebook is used for transmitting the PDSCH based on TB or indicating a PDCCH for releasing the SPS PDSCH, and the second sub-codebook is used for transmitting the PDSCH based on CBG, and the two sub-codebooks are cascaded together into a final HARQ-ACK codebook according to the TB sub-codebook and the CBG sub-codebook sequence. If a plurality of carriers are configured to use CBG-based transmission and the number of configured CBGs is different, a sub-codebook of CBGs is generated based on the maximum number of CBGs.

The 5G NR system does not support simultaneous transmission of PUCCH and PUSCH, 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. When the HARQ-ACK is multiplexed and transmitted on the PUSCH, the corresponding HARQ-ACK codebook needs to be determined in combination with the DAI indication field in the DCI scheduling the PUSCH, specifically, when the UE is configured to use a semi-static codebook, when the UE multiplexes the HARQ-ACK on the PUSCH scheduled in DCI format 0_1 for transmission, the DCI includes a 1-bit DAI field for indicating whether there is HARQ-ACK transmission on the scheduled PUSCH, and if the DAI field value in DCI format 0_1 is 1, the UE reuses the HARQ-ACK codebook determined on the PUCCH according to the configuration for spatial combination of HARQ-ACKs on the PUSCH, and determines the HARQ-ACK codebook transmitted on the PUSCH. If the DAI field value in DCI format 0_1 of the scheduling PUSCH is 0, when the UE is only in M of the main carrier_A,cWhen one SPS PDSCH is received in the set, or one PDSCH scheduled by a DCI format 1_0 or one DCI format 1_0 indicating the release of the SPS PDSCH is received, and the DAI value in the DCI format 1_0 is 1, the UE only generates 1-bit HARQ-ACK for the received one SPS PDSCH or the PDSCH scheduled by the DCI format 1_0 or the DCI indicating the release of the SPS PDSCH; otherwise, the UE does not multiplex HARQ-ACK transmissions on the PUSCH. When the UE is configured to use the dynamic codebook, if the UE is configured to use single carrier transmission, the PDSCH transmission is scheduled or the SPS PDSCH release is instructedThe placed DCI only contains 2 bits of C-DAI indication information and has no T-DAI. When the UE multiplexes HARQ-ACK for transmission on the PUSCH scheduled by DCI format 0_1, a 2-or 4-bit DAI field is included in the DCI to indicate whether there is HARQ-ACK transmission on the scheduled PUSCH and the number of bits for HARQ-ACK. If the UE is not configured to use CBG-based data transmission, the DCI format 0_1 includes a 2-bit DAI. If the UE is configured to use CBG-based data transmission, DCI format 0_1 includes 4-bit DAI, where 2 bits correspond to the first sub-codebook and 2 bits correspond to the second sub-codebook.

In the prior art, only a multiplexing transmission rule that a PUCCH carrying HARQ-ACK and a PUCCH carrying CSI or SR are overlapped and a transmission rule when one PUCCH carrying HARQ-ACK and PUSCH collide are specified.

An illustration of several specific embodiments is given below.

Example 1:

two HARQ-ACK codebooks need to be multiplexed to be transmitted on the same PUCCH or PUSCH under the condition that two PUCCH resources carrying different priority HARQ-ACK are overlapped or two PUCCHs carrying the HARQ-ACK and one PUSCH are overlapped.

Case 1: the predefined N value in the standard is 2, and when the HARQ-ACK codebook of low priority is 0,1 bit, multiplexing feedback needs to be performed according to 2 bits. And feeding back the HARQ-ACK codebook with high priority according to the original bit number. The high priority HARQ-ACK raw codebook contains 6 bits of information, which is (110111).

The HARQ-ACK original codebook of low priority includes 1-bit feedback information, which is (1), and when the feedback is multiplexed, the UE needs to generate 2-bit feedback information, that is (01), for the HARQ-ACK codebook of low priority, where the 1 st bit is NACK of complementary bits. If the two HARQ-ACK codebooks of different priorities are concatenated and then subjected to joint coding feedback, and if the HARQ-ACK feedback information of the high priority is in front, the UE needs to feed back 8-bit HARQ-ACK information on the PUCCH resource subjected to multiplexing feedback, namely (11011101), wherein the first 6 bits are the HARQ-ACK original codebook of the high priority, and the last 2 bits are the actual feedback codebook of the HARQ-ACK of the low priority.

The HARQ-ACK original codebook of the low priority includes 0-bit feedback information, and when the feedback is multiplexed and transmitted, the UE needs to generate 2-bit feedback information for the HARQ-ACK codebook of the low priority, that is, (00), and 2 bits are NACK with complementary bits. If the two HARQ-ACK codebooks of different priorities are concatenated for joint coding feedback, and if the HARQ-ACK feedback information of the high priority is later, the UE needs to feed back 8-bit HARQ-ACK information on the PUCCH resource multiplexed for feedback, that is, (00110111), wherein the first 2 bits are the actual feedback codebook of the low priority HARQ-ACK, and the last 6 bits are the original HARQ-ACK codebook of the high priority.

Case 2: the predefined N value in the standard is 2, any HARQ-ACK codebook is 0, and when 1 bit, multiplexing feedback is required according to 2 bits. The first HARQ-ACK original codebook contains 1 bit of information, which is (1); the second HARQ-ACK raw codebook also contains 1 bit of information, which is (1). When multiplexing transmission feedback, the UE needs to generate 2-bit feedback information for the first HARQ-ACK codebook, that is, (10), where the 2 nd bit is NACK of complementary bit; a 2-bit feedback information, i.e., (10), is generated for the second HARQ-ACK codebook, where the 2 nd bit is also a complementary NACK. When the two codebooks are concatenated and then are fed back in a joint coding manner, the UE feeds back a 4-bit HARQ-ACK codebook on the corresponding resource, that is, (1010), wherein the first 2 bits are the first HARQ-ACK actual transmission codebook, and the last 2 bits are the second HARQ-ACK actual transmission codebook.

Case 3: in the standard, for high-priority HARQ-ACK, the predefined N value is 2, for low-priority HARQ-ACK, the predefined N value is 4, the high-priority HARQ-ACK codebook is 0, when the bit is 1, multiplexing feedback needs to be performed according to 2 bits, and when the low-priority HARQ-ACK codebook is 0,1,2, and 3, multiplexing feedback needs to be performed according to 4 bits.

The high priority HARQ-ACK raw codebook contains 1 bit of information, which is (1). The HARQ-ACK original codebook of the low priority includes 2 bits of information, which is (11), and then when multiplexing feedback, the UE needs to generate 2 bits of feedback information for the HARQ-ACK codebook of the high priority, that is (10), where the 2 nd bit is NACK of complementary bits; 4-bit feedback information, namely (1100), is generated for the low priority HARQ-ACK codebook, wherein the last 2 bits are NACK's of complementary bits. If the two HARQ-ACK codebooks of different priorities are concatenated and then are subjected to joint coding feedback, and if the HARQ-ACK feedback information of the high priority is in the front, the UE needs to feed back 6-bit HARQ-ACK information on the PUCCH resource which is subjected to multiplexing feedback, namely (101100), wherein the first 2 bits are the HARQ-ACK actual transmission codebook of the high priority, and the last 4 bits are the HARQ-ACK actual transmission codebook of the low priority.

The high priority HARQ-ACK raw codebook contains 1 bit of information, which is (1). The low-priority HARQ-ACK original codebook contains 8 bits of information, and is (11101111), when multiplexing feedback, the UE needs to generate 2 bits of feedback information for the high-priority HARQ-ACK codebook, that is, (10), where the 2 nd bit is NACK of complementary bits; the feedback information of the original codebook is used for the low priority HARQ-ACK codebook, i.e., (11101111). If the two HARQ-ACK codebooks of different priorities are concatenated and then are subjected to joint coding feedback, and the HARQ-ACK feedback information of a high priority is assumed to be in the front, the UE needs to feed back 10-bit HARQ-ACK information on the PUCCH resource which is multiplexed and fed back, namely (1011101111), wherein the first 2 bits are the HARQ-ACK actual transmission codebook of the high priority, and the last 8 bits are the HARQ-ACK original transmission codebook of the low priority.

Example 2:

Case 1: the base station indicates that the bit number of the codebook with the low priority is 5 through RRC signaling configuration, and the HARQ-ACK codebook with the low priority always needs to be multiplexed and fed back according to 5 bits. And feeding back the HARQ-ACK codebook with high priority according to the original bit number. The high priority HARQ-ACK raw codebook contains 6 bits of information, which is (110111).

The HARQ-ACK original codebook of low priority includes 1 bit feedback information, which is (1), and when the feedback is multiplexed, the UE needs to generate 5 bits of feedback information, that is (10000), to the HARQ-ACK codebook of low priority, where the last 4 bits are NACK of complementary bits.

Case 2: the base station indicates that the bit numbers of the codebooks with the high and low priorities are both 5 through RRC signaling configuration, that is, the maximum bit number of the codebook is determined to be 5 based on the configuration information of the base station, and then any HARQ-ACK codebook needs to be multiplexed and fed back according to 5 bits. The first HARQ-ACK original codebook contains 1 bit of information, which is (1); the second HARQ-ACK original codebook contains 6 bits of information, which is (101001). When multiplexing transmission feedback, the UE needs to generate 5-bit feedback information, i.e. (10000), for the first HARQ-ACK codebook, where the last 4 bits are NACK of complementary bits; likewise, 5 bits of feedback information are generated for the second HARQ-ACK codebook, i.e. (10100), and the last bit in the original codebook is removed.

Case 3: the number of bits for low priority HARQ-ACK feedback is always 2, which is predefined in the standard.

The high priority HARQ-ACK raw codebook contains 1 bit of information, which is (1). The low-priority HARQ-ACK original codebook contains 5 bits of information, and the bit number is (11011), when multiplexing feedback, the UE generates 1 bit of feedback information to the high-priority HARQ-ACK codebook, namely (1); a 2-bit feedback information is generated for the low priority HARQ-ACK codebook, i.e., (11), where the last three bits in the original codebook are removed.

Case 4: and determining the maximum feedback bit number of the low-priority codebook to be 6 based on the base station configuration information.

Based on the configuration information of the base station, it may be determined that the maximum possible feedback bit number of the codebook with a low priority is 6, for example, the maximum possible feedback bit number is determined based on the maximum number of PDSCH transmission opportunities in the feedback window, the feedback codebook is always determined according to the maximum feedback bit number regardless of how many PDSCHs are received by the terminal in the feedback window, or the maximum possible feedback bit number is determined based on the maximum number of PDCCHs transmitted in all PDCCH detection opportunities corresponding to the feedback slot, the feedback codebook is always determined according to the maximum feedback bit number regardless of how many PDCCHs are actually received by the terminal in the PDCCH detection opportunities, and then the HARQ-ACK codebook with a low priority in this embodiment always needs to be multiplexed and fed back according to 6 bits. And feeding back the HARQ-ACK codebook with high priority according to the original bit number. The high priority HARQ-ACK raw codebook contains 6 bits of information, which is (110111).

The HARQ-ACK original codebook of the low priority includes 0 bit feedback information, and when the feedback is multiplexed and transmitted, the UE needs to generate 6 bit feedback information, that is, (000000), for the HARQ-ACK codebook of the low priority, and all NACK bits are complementary bits.

The multiplexing transmission method of the multiple HARQ-ACK codebooks is provided, the NACK is supplemented to the feedback codebooks with the small bit number to reach the predefined bit number, and the influence on other HARQ-ACK codebooks for multiplexing transmission when the PDSCH corresponding to the HARQ-ACK codebooks with the small bit number loses all packets can be avoided, so that the performance of the multiple HARQ-ACK feedback transmissions in the Rel-16 is ensured.
