Abstract

Provided in the present application are a method for determining a feedback information transmission location and a device, used when one piece of DCI simultaneously indicates resource release with respect to SPS PDSCHs on a plurality of carrier waves, to implement determining a location of an HARQ-ACK for the DCI in an HARQ-ACK codebook. A method of the present application comprises: Determining that a DCI indicates performing resource release with respect to SPS PDSCHs on a plurality of carrier waves; determining a target location of an HARQ-ACK corresponding to the DCI in an HARQ-ACK codebook according to an SLIV for a first SPS PDSCH among released SPS PDSCHs, wherein the first SPS PDSCH is an SPS PDSCH on a target carrier wave among the plurality of carrier waves. Normal feedback of the HARQ-ACK for the DCI is ensured, and uniform understanding for HARQ-ACK transmission by a network-side device and a terminal ensures normal transmission of the HARQ-ACK.

Claims (36)

1 . A method for determining a feedback information transmission location, comprising:

determining that downlink control information (DCI) indicates semi-persistent scheduling (SPS) physical downlink shared channels (PDSCHs) release on a plurality of carriers; and

determining a target location of a hybrid automatic repeat request-acknowledge (HARQ-ACK) corresponding to the DCI in an HARQ-ACK codebook according to a start and length indicator value (SLIV) for a first SPS PDSCH among the released SPS PDSCHs, wherein the first SPS PDSCH is an SPS PDSCH on a target carrier among the plurality of carriers;

wherein in a case that a plurality of released SPS PDSCHs exist on the target carrier, the first SPS PDSCH is an SPS PDSCH with a smallest SPS configuration index among the plurality of released SPS PDSCHs on the target carrier.

2 . The method according to claim 1 , wherein the target carrier comprises:

a carrier in which the DCI is transmitted; or

a carrier with a largest carrier index among the plurality of carriers; or

a carrier with a smallest carrier index among the plurality of carriers; or

each of the plurality of carriers.

3 . The method according to claim 2 , wherein the HARQ-ACK codebook is a semi-static HARQ-ACK codebook.

4 . The method according to claim 1 , wherein the determining the target location of the HARQ-ACK corresponding to the DCI in the HARQ-ACK codebook according to the SLIV for the first SPS PDSCH among the released SPS PDSCHs, further comprises:

determining the target location of the HARQ-ACK corresponding to the DCI in the HARQ-ACK codebook according to a first time unit of the target carrier, wherein the first time unit is a first or last time unit or each time unit among time units overlapping with the DCI; or

determining the target location of the HARQ-ACK corresponding to the DCI in the HARQ-ACK codebook according to a second time unit of the target carrier, wherein the second time unit is a first or last time unit or each time unit among time units overlapping with a time unit in which the DCI is transmitted.

5 . The method according to claim 4 , wherein each of the time units comprises a predefined time period, or a subframe, or a slot, or a sub-slot composed of N symbols; and N is a positive integer.

6 . The method according to claim 5 , wherein the HARQ-ACK codebook is a semi-static HARQ-ACK codebook.

7 . The method according to claim 4 , wherein the HARQ-ACK codebook is a semi-static HARQ-ACK codebook.

8 . The method according to claim 1 , wherein the HARQ-ACK codebook is a semi-static HARQ-ACK codebook.

9 . A non-transitory computer storage medium, storing a computer program thereon, wherein the program, when executed by a processor, implements steps of the method according to claim 1 .

10 . A device for determining a feedback information transmission location, comprising: a processor and a memory;

wherein the processor is configured to read a program in the memory and execute:

determining that downlink control information (DCI) indicates semi-persistent scheduling (SPS) physical downlink shared channels (PDSCHs) release on a plurality of carriers; and

determining a target location of a hybrid automatic repeat request-acknowledge (HARQ-ACK) corresponding to the DCI in an HARQ-ACK codebook according to a start and length indicator value (SLIV) for a first SPS PDSCH among the released SPS PDSCHs, wherein the first SPS PDSCH is an SPS PDSCH on a target carrier among the plurality of carriers;

wherein in a case that a plurality of released SPS PDSCHs exist on the target carrier, the first SPS PDSCH is an SPS PDSCH with a smallest SPS configuration index among the plurality of released SPS PDSCHs on the target carrier.

11 . The device according to claim 10 , wherein the target carrier comprises:

a carrier in which the DCI is transmitted; or

a carrier with a largest carrier index among the plurality of carriers; or

a carrier with a smallest carrier index among the plurality of carriers; or

each of the plurality of carriers.

12 . The device according to claim 11 , wherein the HARQ-ACK codebook is a semi-static HARQ-ACK codebook.

13 . The device according to claim 10 , wherein the processor is further configured to:

determine the target location of the HARQ-ACK corresponding to the DCI in the HARQ-ACK codebook according to a first time unit of the target carrier, wherein the first time unit is a first or last time unit or each time unit among time units overlapping with the DCI; or

determine the target location of the HARQ-ACK corresponding to the DCI in the HARQ-ACK codebook according to a second time unit of the target carrier, wherein the second time unit is a first or last time unit or each time unit among time units overlapping with a time unit in which the DCI is transmitted.

14 . The device according to claim 13 , wherein each of the time units comprises a predefined time period, or a subframe, or a slot, or a sub-slot composed of N symbols, and N is a positive integer.

15 . The device according to claim 14 , wherein the HARQ-ACK codebook is a semi-static HARQ-ACK codebook.

16 . The device according to claim 13 , wherein the HARQ-ACK codebook is a semi-static HARQ-ACK codebook.

17 . The device according to claim 10 , wherein the HARQ-ACK codebook is a semi-static HARQ-ACK codebook.
