Detailed ways

In order to make the technical problems, technical solutions and advantages to be solved by the present disclosure clearer, a detailed description will be given below with reference to the drawings and specific embodiments.

As shown in FIG. 1, an embodiment of the present disclosure provides a method for processing hybrid automatic repeat request feedback, including:

Step 101: Receive first downlink control information, where the first downlink control information is used for multi-slot scheduling, and the first downlink control information includes first indication information, and the first indication information is used to indicate The position of the same feedback time slot corresponding to all the first physical downlink shared channels, where the first physical downlink shared channel is a physical downlink shared channel scheduled with multiple time slots;

Step 102: Feed back first feedback information in the feedback time slot, where the first feedback information is feedback information corresponding to multi-slot scheduling of the first downlink control information.

The method of the embodiment of the present disclosure is applied to a user equipment. Through the

above steps

101 and 102, the first downlink control information DCI for multi-slot scheduling is first received, where the first DCI includes first indication information, and the first The indication information indicates the position of the same feedback time slot corresponding to all the first physical downlink shared channel PDSCH scheduled by the first DCI multi-slot scheduling. The user equipment can determine a feedback time slot through the first indication information. The first feedback information is fed back, that is, the feedback information of all the first PDSCHs corresponding to the first DCI multi-slot scheduling. Therefore, there is no need to separately indicate the feedback time slots of each first PDSCH of the first DCI multi-slot scheduling, which avoids DCI The problem of excessive overhead.

It should be known that the first DCI in this embodiment is carried on the physical downlink control channel PDCCH, and PDSCHs on different time slots are scheduled through the first DCI. Specifically, the feedback information is hybrid automatic repeat request HARQ feedback information.

As shown in the scheduling schematic diagram in Figure 2, the base station configures the user equipment to use two carrier aggregation transmissions, the SCS of carrier 1 is configured to 15 kHz, and the subcarrier spacing of carrier 2 is configured to 60 kHz. The base station performs cross-carrier scheduling on the PDSCH transmitted on carrier 2 through carrier 1, and the physical uplink control channel PUCCH is transmitted on carrier 1. The PDCCH transmitted in time slot n of carrier 1 carries DCI. The DCI is used for multi-slot scheduling to schedule PDSCH transmission in time slot 4n+1 and time slot 4n+2 on carrier 2. The PDCCH transmitted in time slot n+1 of carrier 1 carries DCI, and the DCI is used for multi-slot scheduling to schedule PDSCH transmission in time slot 4n+4, time slot 4n+5, and time slot 4n+7 on carrier 2.

Optionally, in this embodiment, in order to clarify the feedback slot position, the first indication information includes the slot offset;

Assuming that the last PDSCH scheduled by the first DCI corresponds to time slot n, based on the time slot offset K of the first indication information, time slot n+K will be used as the feedback time slot, and HARQ of all PDSCHs scheduled by the first DCI Feedback.

Here, the first time slot is not the time slot position of the current carrier of the second PDSCH, but corresponds to the time slot position on the carrier carrying the HARQ-ACK feedback information corresponding to the PDSCH scheduled by the first DCI. Continuing the example of FIG. 2, the slot offset set (HARQ feedback timing set) configured by the base station contains two K values: {1, 2}. According to the time slot offset K=2 indicated by the DCI received in time slot n, and the last scheduled PDSCH corresponds to time slot n, the user equipment determines that the corresponding feedback time slot is time slot n+2; The time slot offset indicated by the DCI received in n+1 is K=1, and the last PDSCH scheduled corresponds to time slot n+1, then it is determined that the corresponding feedback time slot is time slot n+2.

It should be understood that the feedback information in this embodiment can optionally use a dynamic feedback codebook. Therefore, optionally, after step 101, it further includes:

Optionally, in the case of cross-carrier scheduling,

Here, both μ ₁ and μ ₂ are pre-configured according to the SCS configuration of the subcarrier spacing of the carrier.

Taking the DCI received in time slot n in Figure 2 as an example, since the SCS of carrier 1 is configured as 15 kHz, and the sub-carrier spacing of carrier 2 is configured as 60 kHz, according to the pre-configuration, it can be seen that μ ₁ = 2, and μ ₂ =0.

If the user equipment is not configured to use code block group CGB-based transmission, and is configured on both carriers to be configured for single-codeword transmission, M*N*L=1*4 is generated for the PDSCH scheduled by DCI in time slot n *1=4-bit feedback information. Similarly, in FIG. 2, M*N*L=1*4*1=4-bit feedback information is generated for the PDSCH scheduled by the DCI in the time slot n+1. In this way, a total of 8 bits of feedback information is generated.

In this embodiment, because the first feedback information corresponds to all the scheduled physical downlink shared channels, in order to better feedback each PDSCH, optionally, the first downlink control information is All the scheduled physical downlink shared channels generate first feedback information of M*N*L bits, as shown in Figure 3, including:

Step 301: Determine, according to the second time slot where the first physical downlink shared channel is located, the time slot ordering number of the second time slot among the multiple time slots scheduled by the first downlink control information;

Step 302: Determine the position of the second feedback information of the first physical downlink shared channel in the first feedback information according to the time slot sorting number.

Here, the second feedback information is the feedback information of a PDSCH scheduled by the first DCI. According to the

above steps

301 and 302, the user equipment will pass the corresponding bit position in the generated first feedback information of M*N*L bits. To realize the feedback of each PDSCH.

For example, as shown in Figure 2, the DCI received in time slot n of carrier 1 is scheduled for the PDSCH in time slot 4n+1 on carrier 2, and its time slot arrangement number is 2; the PDSCH in time slot 4n+2 on carrier 2 is scheduled , And its time slot arrangement number is 3. And because the feedback information of DCI scheduling received in time slot n of carrier 1 and the feedback information of DCI scheduling received in time slot n+1 of carrier 1 will be fed back in the same feedback time slot,

Considering the corresponding configuration of the user equipment, specifically, step 302 includes:

Where, x is the sequence number of the time slot, y=M*L*x-1, and p=M*L.

Here, for the second feedback information for only one PDSCH, that is, ACK feedback information, when the number of bits is equal to 1, the second feedback information will be placed at the x-th bit position in the first feedback information, such as M=1 , L=1 In N time slots, PDSCH transmission is scheduled on the a-th time slot, and the corresponding 1-bit feedback information is placed at the a-th bit position in the N-bit feedback information. When the number of bits is greater than 1, on the one hand, the second feedback information can be placed at consecutive p bit positions starting from the yth bit position in the first feedback information, such as M=2, L=1 when N In the slot, PDSCH transmission is scheduled on the a-th time slot, and the corresponding 2-bit feedback information is placed in the 2a-1 and 2a-th bit positions in the N-bit feedback information; on the other hand, it can be The first feedback information starts with the x-th bit position, and the second feedback information is placed at p bit positions where N is the period. For example, M=2, L=1 in N time slots, the a-th time slot If PDSCH transmission is scheduled on the above, the corresponding 2-bit feedback information is placed at the ath and a+Nth bit positions in the N-bit feedback information.

Continuing the example in Figure 2, a total of 8 bits of feedback information are generated, where the second bit corresponds to the PDSCH transmitted in carrier 2 time slot 4n+1, and the third bit corresponds to the PDSCH transmitted in carrier 2 time slot 4n+2 , The fifth bit corresponds to the PDSCH transmitted in carrier 2 timeslot 4n+4, the sixth bit corresponds to the PDSCH transmitted in carrier 2 timeslot 4n+5, and the eighth bit corresponds to carrier 2 timeslot 4n+7 PDSCH in transmission.

In addition, when the number of PDSCH slots actually scheduled by the multi-slot scheduling DCI is less than N, the generated first feedback information of M*N*L bits cannot completely correspond to the scheduled PDSCH. Therefore, optionally, the pair The generation of first feedback information of M*N*L bits for all physical downlink shared channels scheduled by the first downlink control information includes:

In this way, the user equipment will generate negative NACK feedback information for the time slots where the PDSCH is not received, for example, fill the remaining bit positions of the first feedback information with 0.

Continuing the example of FIG. 2, if the user equipment demodulates all PDSCHs correctly, the first feedback information (HARQ-ACK codebook) fed back in the PUCCH resource of time slot n+2 is 01101101.

In addition, based on the configuration of the user equipment, in this embodiment, optionally, when the user equipment is configured for multi-carrier transmission and the maximum schedulable physical downlink shared channel of the first downlink control information on each carrier of the current multi-carrier The number of time slots is different. Before or after step 101, it also includes:

According to the above content, the user equipment will receive the second DCI before or after receiving the first DCI, and the second DCI is used for single-slot scheduling, multi-slot scheduling or channel release (ie semi-persistent scheduling SPS PDSCH release), and When the second DCI is used for multi-slot scheduling, the maximum number of physical downlink shared channel time slots that can be scheduled by the second DCI is greater than or less than the number of physical downlink shared channel time slots that can be scheduled for the first DCI, In this way, when the fourth feedback information feedback is performed for the same feedback time slot, in addition to the first feedback information, it also includes feedback information corresponding to single-slot scheduling, multi-slot scheduling, and channel release (fifth feedback information). In this way, more efficient feedback can be achieved on the feedback slot.

For example, based on the example in Figure 2, suppose that the base station also instructs SPS PDSCH release (channel release) on carrier 2 through a DCI in time slot n of carrier 1, and also schedules time slot n of carrier 1 through another DCI. For PDSCH transmission (single-slot scheduling), the feedback time slot of both is also time slot n+2. Then, the SPS PDSCH release and the feedback information of the PDSCH in time slot n of carrier 1 will also be transmitted in the PUCCH resource of time slot n+2.

Optionally, before feeding back the fourth feedback information in the feedback time slot, the method further includes:

Generating the fourth feedback information;

Here, for the realization of generating the first feedback information and the fifth feedback information, on the one hand, according to the type of DCI, the feedback information corresponding to single-slot scheduling or channel release is used as the first subcodebook, corresponding to the feedback information of multi-slot scheduling As the second sub-codebook, it is obtained through the concatenation of the first sub-codebook and the second sub-codebook; on the other hand, the feedback information of the carrier channels belonging to the same multi-slot scheduling configuration is used as the same sub-codebook. The cascade of multiple sub-codebooks is obtained. Among them, the cascade will sort the sub-codebooks based on preset rules. For example, for the cascade of the first sub-codebook and the second sub-codebook, you can put the first sub-codebook first and then the second sub-codebook. It is also possible to put the second sub-codebook first and then the first sub-codebook.

In addition, optionally, when the second downlink control information is used for multi-slot scheduling, the second subcodebook is M*N _max *L*I bits of information;

Here, for the case where the second DCI is used for multi-slot scheduling, refer to the generation of the first feedback information, and the second subcodebook is M*N _max *L*I bits of information.

For example, based on the example in Figure 2, suppose that the base station also instructs SPS PDSCH release (channel release) on carrier 2 through a DCI in time slot n of carrier 1, and also schedules time slot n of carrier 1 through another DCI. For PDSCH transmission (single-slot scheduling), the feedback time slot of both is also time slot n+2, and the feedback time slot has the following realizations:

Implementation 1: Carrier 1 instructs the SPS PDSCH on carrier 2 to release the DCI and the feedback information corresponding to the PDSCH transmitted in time slot n as a sub-codebook. Carrier 2 time slot 4n+1/4n+2/4n+4/4n+ The feedback information corresponding to the PDSCH transmitted in 5/4n+7 is a sub-codebook. Assuming that the user equipment is configured for single codeword transmission on both carriers, the first sub-codebook contains 2 feedback bits, and the second sub-codebook contains 8 feedback bits. These 8 bits (corresponding to Figure 2 two The determination of the feedback information of the first DCI scheduling) is as described above, and will not be repeated here. The cascading sequence is that the 2-bit feedback information corresponding to the DCI that does not use multi-slot scheduling comes first, and the 10-bit feedback information corresponding to the feedback information corresponding to the DCI that uses multi-slot scheduling is last. Of course, the cascading sequence may also be that the 10-bit feedback information corresponding to the feedback information corresponding to the DCI using multi-slot scheduling is first, and the 2-bit feedback information corresponding to the DCI not using the multi-slot scheduling is last.

Implementation 2: The feedback information corresponding to the PDSCH transmitted in carrier 1 time slot n is a subcodebook, carrier 1 indicates the DCI released by the SPS PDSCH on carrier 2, and carrier 2 time slot 4n+1/4n+2/4n+4/ The feedback information corresponding to the DCI for transmitting the PDSCH in 4n+5/4n+7 is a sub-codebook. The user equipment is configured with single codeword transmission on both carriers, so the first subcodebook contains only 1 feedback bit, and the second subcodebook contains 12 feedback bits, that is, the PDSCH scheduled for 3 DCIs Generate 4-bit feedback information respectively. For the DCI indicating the release of SPS PDSCH on carrier 2, the user equipment can generate repeated bit information based on the demodulation result, for example, the user equipment generates a 4-bit ACK when the demodulation is correct, or generates a 4-bit NACK when the demodulation fails, or the user equipment It is also possible to generate 1-bit valid feedback information and supplement NACK in the remaining 3-bit positions. The user equipment cascades the two sub-codebooks to obtain 13-bit feedback information. The specific cascading sequence can be cascaded according to the carrier number sequence, for example, the 1-bit feedback information corresponding to carrier 1 comes first, and the 12-bit feedback information corresponding to carrier 2 comes later. Of course, it is also possible that the 12-bit feedback information corresponding to carrier 2 comes first, and the 1-bit feedback information corresponding to carrier 1 comes later.

Implementation 3: There are 3 DCIs in the same PDCCH detection opportunity in time slot n of carrier 1, which are used to indicate the release of SPS PDSCH on carrier 2, scheduling PDSCH transmission in time slot n of carrier 1, and scheduling For PDSCH transmission, there is 1 DCI in the time slot n+1 of carrier 1, and then 4-bit feedback information is generated for each DCI, and 16-bit feedback information is generated in total. The first 4 bits of information are feedback information indicating the DCI released by the SPS PDSCH on carrier 2. The user equipment can generate repeated bit information based on the demodulation result, or generate 1-bit effective feedback information, and supplement the remaining 3 bits. NACK. The 5th to 8th bits of information are feedback information for the PDSCH transmission in time slot n of carrier 1. Similarly, the user equipment can generate repeated bit information based on the demodulation result, or it can generate 1-bit effective feedback information. NACK is added to the bit position. The final 8-bit information (corresponding to the feedback information of the two first DCI scheduling in FIG. 2) is determined as described above, and will not be repeated here.

Generally speaking, in this embodiment, whether the DCI is a multi-slot scheduling DCI can be determined according to the DCI format or the carrier configuration corresponding to the DCI scheduling information. For example, the DCI using multi-slot scheduling corresponds to the DCI format 1_1 corresponding to the PDSCH transmitted on the carrier configured to use multi-slot scheduling, and the DCI not using multi-slot scheduling corresponds to the PDSCH transmitted on the carrier that is not configured to use multi-slot scheduling. DCI format 1_0 and DCI format 1_1, the DCI indicating SPS PDSCH release transmitted on the carrier configured to use multi-slot scheduling, and the DCI format 1_0 corresponding to the PDSCH transmitted on the carrier configured to use multi-slot scheduling.

Further optionally, the first downlink control information and the second downlink control information include:

For example, based on the example in Figure 2, suppose that the base station also instructs the release of SPS PDSCH on carrier 2 through a DCI in time slot n of carrier 1, and also schedules PDSCH transmission in time slot n of carrier 1 through another DCI. The feedback time slot of the person is also time slot n+2. In the first implementation of the above feedback method, the base station sets the C-DAI (second indication information) and T-DAI (third indication information) in the DCI corresponding to the two subcodebooks respectively, that is, for multi-slot scheduling based C-DAI and T-DAI in DCI and DCI that are not used for multi-slot scheduling are counted separately. In the second implementation of the above feedback method, the base station sets the C-DAI and T-DAI in the DCI of the two carriers respectively, that is, sets the C-DAI and T-DAI in the DCI of carrier 1 and the DCI of carrier 2 respectively. Count: Carrier 1 time slot n indicates that the SPS PDSCH on carrier 2 releases the DCI in which C-DAI is 1 and T-DAI is 2; carrier 1 time slot n schedules time slot 4n+1 and time slot 4n on carrier 2 The values of C-DAI and T-DAI in the DCI transmitted by PDSCH in +2 are both 2; the values of C-DAI and T-DAI in the DCI of time slot n+1 of carrier 1 are both 3. Time slot 4n on carrier 2 is scheduled +4, PDSCH transmission in time slot 4n+5 and time slot 4n+7. In the third implementation of the above feedback method, the base station counts the C-DAI and T-DAI in the DCI of carrier 1 and the DCI of carrier 2 jointly: instructs the release of SPS PDSCH on carrier 2, and schedules the In the DCI for PDSCH transmission and PDSCH transmission on scheduling carrier 2, the corresponding C-DAI is 1/2/3, T-DAI is 3, and the C-DAI and T contained in the DCI in time slot n+1 of carrier 1 -DAI are all 4.

As shown in Figure 4 below, it is explained that the user equipment's feedback information corresponding to the carrier using multi-slot scheduling and the carrier not using multi-slot scheduling is divided into two subcodebooks. At the same time, because there are multiple multi-slot scheduling carriers and the maximum schedulable The number of time slots is different. For sub-codebooks of carriers that use multi-slot scheduling, the user equipment needs to determine the usage instructions of the feedback codebook size based on the maximum number of PDSCH time slots that can be scheduled by DCI. At this time, the base station configures the user equipment to use three carrier aggregation transmissions, the SCS of carrier 1 is configured to 15kHz, the subcarrier spacing of carrier 2 is configured to 30kHz, and the subcarrier spacing of carrier 3 is configured to 60kHz. The base station performs cross-carrier scheduling on the PDSCHs transmitted on carrier 2 and carrier 3 through carrier 1, PUCCH is transmitted on carrier 1, and the HARQ feedback timing set configured by the base station includes two K values: {1,2}. The base station schedules the PDSCH transmission of time slot n of carrier 1 in the first PDCCH detection opportunity of carrier 1, and the corresponding C-DAI is 1. In the first PDCCH detection opportunity of carrier 1, PDSCH transmissions of time slots 4n+1 and 4n+2 of carrier 3 are also scheduled, and the corresponding C-DAI and T-DAI are both 1. In the second PDCCH detection opportunity of carrier 1, PDSCH transmission of time slot 2n+1 of carrier 2 is scheduled, and the corresponding C-DAI and T-DAI are both 2. In the third PDCCH detection opportunity of carrier 1, the PDSCH transmission of time slot 4n+4 of carrier 3 is scheduled, and the corresponding C-DAI and T-DAI are both 3. In the fourth PDCCH detection opportunity of carrier 1, the PDSCH transmission of time slot 2n+2 of carrier 2 is scheduled, and the corresponding C-DAI and T-DAI are both 4. The first subcodebook only contains feedback information corresponding to PDSCH transmission in carrier 1 time slot n, and the second subcodebook contains feedback information for PDSCH transmission in carrier 2 and carrier 3. Assuming that the user equipment is configured for single codeword transmission on all three carriers, the first subcodebook contains only 1 feedback bit, the second subcodebook contains 16-bit feedback information, and the second subcodebook is It is determined based on the last received T-DAI=4 and the maximum number of multi-slot scheduling of carrier 3 is 4. The first 4 bits of the 16-bit feedback information are the feedback information of the PDSCH scheduled by DCI with C-DAI=1, corresponding to time slots 4n to 4n+3 on carrier 3; the 5th to 8th bits are for C-DAI=2 The feedback information of the PDSCH scheduled by DCI corresponds to the time slots 2n to 2n+1 on carrier 2 (the user equipment generates 2-bit feedback information for the two time slots, and supplements NACK in the remaining 2-bit positions); 12 bits are the feedback information of the PDSCH scheduled by the DCI with C-DAI=3, corresponding to the time slots 4n+4 to 4n+7 on carrier 3; the 13th to 16th bits are the feedback information for the PDSCH scheduled by the DCI with C-DAI=4 Information, corresponding to time slots 2n+2 to 2n+3 on carrier 2 (the user equipment generates 2-bit feedback information for the two time slots and adds NACK to the remaining 2-bit positions); the user equipment adds two more subcodes This is cascaded, and finally 17-bit feedback information is generated. Assuming that the user equipment correctly receives all PDSCHs, the feedback bits generated by the user equipment are 10110010010001000.

In summary, the method of the embodiments of the present disclosure first receives the first downlink control information DCI for multi-slot scheduling, where the first DCI includes first indication information, and the first indication information indicates that the first DCI The position of the same feedback time slot corresponding to all the first physical downlink shared channel PDSCHs scheduled by multiple time slots, the user equipment can determine a feedback time slot through the first indication information, and feed back the first feedback information on the feedback time slot, That is, it corresponds to the feedback information of all the first PDSCHs of the first DCI multi-slot scheduling. Therefore, there is no need to separately indicate the feedback time slots of each first PDSCH of the first DCI multi-slot scheduling, which avoids the problem of excessive DCI overhead.
