Abstract

A method for processing a HARQ-ACK feedback, applied to a user equipment (UE), the method including: sending, in response to a collision between a first physical uplink control channel (PUCCH) resource and a preset transmission resource, a hybrid automatic retransmission request acknowledgement (HARQ-ACK) feedback on a second PUCCH resource; wherein the first PUCCH resource is a resource for transmitting the HARQ-ACK feedback of a downlink semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH) resource, and the second PUCCH resource is located after the first PUCCH resource in a time domain and does not collide with the preset transmission resource.

Claims (39)

1. A method for processing a HARQ-ACK feedback, performed by a user equipment (UE), comprising:

sending, in response to a collision between a first physical uplink control channel (PUCCH) resource and a preset transmission resource, a hybrid automatic retransmission request acknowledgement (HARQ-ACK) feedback on a second PUCCH resource; wherein the first PUCCH resource is a resource for transmitting the HARQ-ACK feedback of a downlink semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH) resource, and the second PUCCH resource is located after the first PUCCH resource in a time domain and does not collide with the preset transmission resource;

wherein the second PUCCH resource is determined based on an increased K1 value, the increased K1 value is increased based on a K1 value, the K1 value is a slot offset between a slot where the HARQ-ACK feedback is located and a slot where an SPS PDSCH resource corresponding to the HARQ-ACK feedback is located, and the K1 value is less than or equal to a preset value.

2. The method according to claim 1 , wherein the preset transmission resource comprises:

the preset transmission resource that is semi-statically configured, or the preset transmission resource that is dynamically configured.

3. The method according to claim 1 , wherein the preset transmission resource comprises at least one of:

a PDSCH resource, a physical uplink shared channel (PUSCH) resource, a physical downlink control channel (PDCCH) resource, or a PUCCH resource for transmitting other than the HARQ-ACK feedback.

4. The method according to claim 1 , further comprising:

increasing the K1 value; and

determining the second PUCCH resource based on the increased K1 value.

5. The method according to claim 4 , wherein increasing the K1 value comprises:

increasing the K1 value according to the preset transmission resource colliding with the first PUCCH resource.

6. A method for processing a HARQ-ACK feedback, performed by a base station, comprising:

receiving, in response to a collision between a first physical uplink control channel (PUCCH) resource and a preset transmission resource, a hybrid automatic retransmission request acknowledgement (HARQ-ACK) feedback on a second PUCCH resource; wherein the first PUCCH resource is a resource for transmitting the HARQ-ACK feedback of a downlink semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH) resource, and the second PUCCH resource is located after the first PUCCH resource in a time domain and does not collide with the preset transmission resource;

wherein the second PUCCH resource is determined based on an increased K1 value, the increased K1 value is increased based on a K1 value, the K1 value is a slot offset between a slot where the HARQ-ACK feedback is located and a slot where an SPS PDSCH resource corresponding to the HARQ-ACK feedback is located, and the K1 value is less than or equal to a preset value.

7. The method according to claim 6 , wherein the preset transmission resource comprises:

the preset transmission resource that is semi-statically configured, or the preset transmission resource that is dynamically configured.

8. The method according to claim 6 , wherein the preset transmission resource comprises at least one of:

a PDSCH resource, a physical uplink shared channel (PUSCH) resource, a physical downlink control channel (PDCCH) resource, or a PUCCH resource for transmitting other than the HARQ-ACK feedback.

9. The method according to claim 6 , further comprising:

increasing the K1 value; and

determining the second PUCCH resource based on the increased K1 value.

10. The method according to claim 9 , wherein increasing the K1 value comprises:

increasing the K1 value according to the preset transmission resource colliding with the first PUCCH resource.

11. A communication device, comprising:

a processor; and

a memory, configured to store an instruction executable by the processor;

wherein the processor, when running the executable instruction applied to a user equipment (UE) for processing a HARQ-ACK feedback, is configured to:

send, in response to a collision between a first physical uplink control channel (PUCCH) resource and a preset transmission resource, a hybrid automatic retransmission request acknowledgement (HARQ-ACK) feedback on a second PUCCH resource; wherein the first PUCCH resource is a resource for transmitting the HARQ-ACK feedback of a downlink semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH) resource, and the second PUCCH resource is located after the first PUCCH resource in a time domain and does not collide with the preset transmission resource;

wherein the second PUCCH resource is determined based on an increased K1 value, the increased K1 value is increased based on a K1 value, the K1 value is a slot offset between a slot where the HARQ-ACK feedback is located and a slot where an SPS PDSCH resource corresponding to the HARQ-ACK feedback is located, and the K1 value is less than or equal to a preset value.

12. A non-transitory computer-readable storage medium, wherein the computer storage medium stores with a computer-executable program, and when the executable program is executed by a processor, the method for processing the HARQ-ACK feedback according to claim 1 is implemented.

13. The communication device according to claim 11 , wherein the processor is further configured to:

increase the K1 value; and

determine the second PUCCH resource based on the increased K1 value.

14. A communication device, comprising:

a processor; and

a memory, configured to store an instruction executable by the processor;

wherein the processor is configured to implement the method for processing the HARQ-ACK feedback according to claim 6 when running the executable instruction.

15. A non-transitory computer-readable storage medium, wherein the computer storage medium stores with a computer-executable program, and when the executable program is executed by a processor, the method for processing the HARQ-ACK feedback according to claim 6 is implemented.
