Technical field

The present disclosure relates to the field of communication technology, and in particular to a method, device, terminal and network device for transmitting information of Hybrid Automatic Repeat Request-Acknowledgement (HARQ-ACK).

Background technique

With the development and change of mobile communication business requirements, the International Telecommunication Union (International Telecommunication Union, ITU) Telecommunications Standards Branch and other organizations have begun to study new wireless communication systems (that is, the fifth-generation new wireless access technology) for future mobile communication systems. (5th Generation New RAT, 5G NR)). 5G NR supports multiple subcarrier spacing configurations. Specifically, the subcarrier spacing configuration can be 15kHz, 30kHz, 60kHz, 120kHz, and 240kHz. When the subcarrier spacing is configured to 60kHz, it supports the use of conventional cyclic prefix (CP). (I.e. non-extended CP) and extended CP transmission, other sub-carrier spacing configurations only support the use of regular CP transmission.

In addition, 5G NR supports flexible timing relationships. For the physical downlink shared channel (Physical Downlink Shared CHannel, PDSCH), the physical downlink control channel (Physical Downlink Control CHannel, PDCCH) that carries its scheduling information indicates the scheduling timing relationship between the PDSCH and the PDCCH (Scheduling timing, namely K0) and PDSCH Confirm the feedback timing relationship between HARQ-ACK (HARQ-ACK timing, namely K1) to its corresponding hybrid automatic repeat request. Specifically, the time domain resource allocation indication field in the Downlink Control Information (DCI) format used by the PDCCH indicates the time slot offset K0 between the time slot where the PDSCH is located and the time slot where the DCI is located; the PDSCH to HARQ in the DCI format -The ACK feedback timing indicator field indicates the number of time slots K1 between the end of the PDSCH and the beginning of HARQ-ACK, that is, the PDSCH transmission at the end position in time slot n performs HARQ-ACK transmission in time slot n+K1, as shown in Figure 1. (The ECP in the figure stands for extended CP, which is extended CP, and NCP stands for normal CP, which is regular CP). The full set of K1 is {0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15}, and it is usually configured with up to 8 values for the terminal. The value of K1 is in units of time slots, that is, K1=1 means one time slot is separated. K1=0 corresponds to the last physical uplink control channel (PUCCH) time slot that overlaps with the received PDSCH or the PDCCH indicating semi-persistent scheduling (Semi-Persistent Scheduling, SPS) PDSCH release.

In the related art, in the NR communication system, the HARQ-ACK feedback is supported to use a semi-static codebook scheme and a dynamic codebook scheme.

When configured to use the semi-static HARQ-ACK codebook, the terminal (User Equipment, UE) first according to HARQ-ACK feedback timing (K1), semi-static time slot structure (if configured) and PDSCH candidate time domain resource allocation information Determine the PDSCH position set M _A,c corresponding to the HARQ-ACK feedback in the same time slot n on each carrier _c . Then, according to M _A,c , 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 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 set configured by the higher layer 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 configured to use the dynamic HARQ-ACK codebook, the UE determines the corresponding PDCCH detection position set based on the HARQ feedback timing set configured by high-layer signaling and the scheduling timing relationship between the PDSCH and the PDCCH contained in the configured time domain allocation resource table , And then based on the count downlink assignment index (Counter Downlink Assignment Index, C-DAI) and the total downlink assignment index (Total Downlink Assignment Index, T-DAI) contained in the DCI received in the PDCCH detection position set to determine HARQ- ACK codebook.

Specifically, in 5G NR, in a carrier aggregation (Carrier Aggregation, CA) scenario, when a carrier with an extended CP configuration and a carrier with a regular CP are aggregated, the slot boundaries may not be aligned. According to the requirements of the HARQ feedback timing and feedback codebook in the standard of the related technology, some time slots have no corresponding feedback positions in the feedback codebook. For example, the terminal is configured to use Carrier 1 and Carrier 2 for carrier aggregation. Carrier 1 is the main carrier. When the subcarrier spacing of Carrier 1 is configured to 60kHz and the extended CP configuration is used, the subcarrier spacing of Carrier 2 is also 60kHz but the regular CP is used. During configuration, if the configured HARQ feedback timing set contains only one K1 value of 2, according to the relevant technical standards, K1=0 indicates the last physical uplink control channel PUCCH that overlaps the received physical downlink shared channel PDSCH Transmission time slot, as shown in Figure 2, K1=0 means that the PDSCH transmitted in time slot n on carrier 2 corresponds to time slot n+1 on carrier 1 for feedback, so K1=2 corresponds to carrier 2 The PDSCH transmitted in time slot n corresponds to the time slot n+3 on carrier 1, and the PDSCH transmitted in time slot n+1 on carrier 2 is also fed back in time slot n+3 on carrier 1. However, according to the standard For the PUCCH transmitted in time slot n+3, when determining the feedback codebook, only one downlink time slot corresponding to carrier 2 that is time slot n+1 can be found according to the value of K1 when determining the feedback codebook. The static codebook still uses the dynamic codebook scheme. The PDSCH transmitted in time slot n on carrier 2 has no corresponding feedback position in the feedback codebook. Therefore, it is necessary to consider modifying the HARQ feedback timing determination method of the related technology.

It can be seen from the above that in the CA scenario, when a carrier with an extended CP configuration and a carrier with a regular CP are aggregated, there is a situation where the slot boundaries are not aligned. According to the HARQ feedback timing and feedback codebook determination scheme defined in the standards of related technologies, in some cases, some time slots have no corresponding feedback positions in the feedback codebook.

Among them, formula one is:

The method for transmitting the HARQ-ACK information provided in the embodiments of the present disclosure will be further described below.

In response to the above technical problems, the embodiments of the present disclosure provide a HARQ-ACK information transmission method, which mainly involves: if the UE detects that the end position is in the preset channel of time slot n (that is, if the UE detects the end position of the preset channel When the time slot is time slot n), the UE sends the HARQ-ACK information corresponding to the preset channel in the PUCCH of time slot n+k, where k is the HARQ-ACK feedback timing, that is, when the end position of the preset channel is The number of slot offsets between the slots where the HARQ-ACK information corresponding to the slot and the preset channel is located, where k is the K1 value configured by the higher layer or the K1 value indicated in the DCI issued by the network device; in the above description, time Slot n is determined based on PDSCH transmission carrier configuration information, the number of slot offsets indicated by k is determined based on PUCCH transmission carrier configuration information, and slot n+k is determined based on PUCCH transmission carrier configuration information; preset channels include PDSCH or indicate SPS PDSCH release PDCCH transmission;

Specifically, the UE may determine the PUCCH transmission slot corresponding to k=0 (that is, the HARQ-ACK information feedback slot) based on any of the following methods:

Method 1: Use different HARQ-ACK information feedback timing determination methods for different carrier aggregation situations:

When the CP of the PUCCH transmission carrier (which can be the primary carrier) is configured as an extended CP configuration and the subcarrier interval is 60kHz, if the CP of the transmission carrier of the preset channel is configured as a regular (ie non-extended) CP configuration and the subcarrier interval is 60kHz Or 120kHz, then k=0 corresponds to the first PUCCH transmission time slot that overlaps with the time slot where the end position of the preset channel is located; otherwise k=0 corresponds to the last PUCCH that overlaps the time slot where the end position of the preset channel is located Transmission time slot;

Method 2: Use the same HARQ-ACK information feedback timing determination method for different carrier aggregation situations:

However, k is the K1 value determined by the network device and delivered to the terminal through high-level signaling or DCI.

The terminal uses K1=0 as the reference point to determine the actual DCI indication K1 or the PUCCH transmission time slot corresponding to the K1 value configured by the upper layer, that is, for the PDSCH received by the terminal in time slot 4n and time slot 4n+1 on carrier 3, K1=0 corresponds to time slot 2n on carrier 1, then K1=2 corresponds to time slot 2n+2 on carrier 1; for the PDSCH received by the terminal in time slot 4n+2 and time slot 4n+3 on carrier 3, K1=0 corresponds to time slot 2n on carrier 1. +1, then K1=2 corresponds to the time slot 2n+3 on carrier 1;

For the PDSCH received by the terminal on carrier 4, K1=0 corresponds to the last PUCCH transmission time slot that overlaps with the time slot where the end position of the preset channel is located. The terminal uses K1=0 as a reference point to determine the actual DCI indicated K1 Or the PUCCH transmission time slot corresponding to the K1 value configured by the upper layer, that is, for the PDSCH received by the terminal in time slot n on carrier 4, K1=0 corresponds to time slot 2n+1 on carrier 1, and K1=2 corresponds to Time slot 2n+3 on carrier 1;

When using the second method to determine the HARQ feedback timing, as shown in Figure 6:

For the PDSCH received by the terminal on carrier 4, K1=0 corresponds to the first PUCCH transmission time slot that overlaps with the time slot where the end position of the preset channel is located. The terminal uses K1=0 as the reference point to determine the actual DCI indication K1 or the PUCCH transmission time slot corresponding to the K1 value configured by the higher layer, that is, for the PDSCH received by the terminal in time slot n on carrier 4, K1=0 corresponds to time slot 2n on carrier 1, and K1=2 corresponds to carrier Time slot 2n+2 on 1.
