Abstract

A feedback information determining method and apparatus, and a storage medium. The method comprises: a terminal determines, according to the position of each transmission resource in multiple transmission resources, a HARQ process index corresponding to the transmission resource; the terminal determines a first feedback information codebook according to the HARQ process indexes corresponding to the multiple transmission resources, wherein the first feedback information codebook comprises feedback information corresponding to the multiple transmission resources.

First claim

The invention claimed is:

1. A method for determining feedback information, comprising:
determining, by a terminal according to a position of each of a plurality of transmission resources, a hybrid automatic repeat request (HARQ) process index corresponding to each transmission resource; and
determining, by the terminal, a first feedback information codebook according to HARQ process indexes corresponding to the plurality of transmission resources, wherein the first feedback information codebook comprises feedback information corresponding to the plurality of transmission resources, wherein the plurality of transmission resources are allocated to a semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH);
wherein responsive to that the HARQ process indexes corresponding to at least two transmission resources in the plurality of transmission resources are a first process index, a feedback information bit associated with the first process index in the first feedback information codebook is set as feedback information corresponding to one of a plurality of SPS PDSCHs received on the at least two transmission resource; and
the one of the plurality of SPS PDSCH is a first SPS PDSCH or a last SPS PDSCH.

2. The method of claim 1 , wherein the first feedback information codebook comprises a plurality of feedback information bits; and
the plurality of feedback information bits are ordered according to an order of the HARQ process indexes corresponding to the plurality of transmission resources.

3. The method of claim 1 , wherein the first feedback information codebook further comprises feedback information of a dynamic scheduling PDSCH.

4. The method of claim 3 , wherein the first feedback information codebook comprises:
a first subcodebook comprising the feedback information of the dynamic scheduling PDSCH; and
a second subcodebook comprising feedback information corresponding to the plurality of transmission resources.

5. The method of claim 4 , wherein responsive to that a HARQ process index of the dynamic scheduling PDSCH received by the terminal is a first process index and a HARQ process index corresponding to at least one transmission resource in the plurality of transmission resources is the first process index, the first feedback information codebook comprises the feedback information of the dynamic scheduling PDSCH and feedback information corresponding to transmission resources, other than the at least one transmission resource, in the plurality of transmission resources.

6. The method of claim 5 , wherein the first feedback information codebook comprises:
the first subcodebook comprising the feedback information of the dynamic scheduling PDSCH; and
the second subcodebook comprising the feedback information corresponding to transmission resources, other than the at least one transmission resource, in the plurality of transmission resources.

7. The method of claim 4 , wherein responsive to that a HARQ process index of the dynamic scheduling PDSCH received by the terminal is a first process index and a HARQ process index corresponding to at least one transmission resource in the plurality of transmission resources is the first process index, the terminal does not receive SPS PDSCH on the at least one transmission resource.

8. The method of claim 4 , wherein responsive to that a HARQ process index of the dynamic scheduling PDSCH received by the terminal is a first process index and a HARQ process index corresponding to at least one transmission resource in the plurality of transmission resources is the first process index, at least one SPS PDSCH is received by the terminal on the at least one transmission resource:
feedback information bits associated with the first process index are set as the feedback information of the dynamic scheduling PDSCH and feedback information of a last PDSCH of the at least one SPS PDSCH received by the terminal; or
a feedback information bit associated with the first process index is set as the feedback information of the dynamic scheduling PDSCH.

9. A device for determining feedback information, comprising:
a processor; and
a memory for storing a computer program executable on the processor,
wherein the processor is configured to:
determine a hybrid automatic repeat request (HARQ) process index corresponding to each transmission resource according to a position of each of a plurality of transmission resources; and
determine a first feedback information codebook according to HARQ process indexes corresponding to the plurality of transmission resources, wherein the first feedback information codebook comprises feedback information corresponding to the plurality of transmission resources, wherein the plurality of transmission resources are allocated to a semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH);
wherein responsive to that the HARQ process indexes corresponding to at least two transmission resources in the plurality of transmission resources are a first process index, a feedback information bit associated with the first process index in the first feedback information codebook is set as feedback information corresponding to one of a plurality of SPS PDSCHs on the at least two transmission resources; and
the one of the plurality of SPS PDSCH is a first SPS PDSCH or a last SPS PDSCH.

10. The device of claim 9 , wherein the first feedback information codebook comprises a plurality of feedback information bits; and
the plurality of feedback information bits are ordered according to an order of the HARQ process indexes corresponding to the plurality of transmission resources.

11. The device of claim 9 , wherein the first feedback information codebook comprises:
a first subcodebook comprising feedback information of a dynamic scheduling PDSCH; and
a second subcodebook comprising feedback information corresponding to the plurality of transmission resources.

12. The device of claim 11 , further comprising a transceiver, wherein
responsive to that a HARQ process index of the dynamic scheduling PDSCH received by the transceiver is a first process index and a HARQ process index corresponding to at least one transmission resource in the plurality of transmission resources is the first process index, the transceiver does not receive SPS PDSCH on the at least one transmission resource.

13. The device of claim 11 , further comprising a transceiver,
wherein responsive to that a HARQ process index of the dynamic scheduling PDSCH received by the transceiver is a first process index and a HARQ process index corresponding to at least one transmission resource in the plurality of transmission resources is the first process index, at least one SPS PDSCH is received by the transceiver on the at least one transmission resource:
feedback information bits associated with the first process index are set as the feedback information of the dynamic scheduling PDSCH and feedback information of a last PDSCH of the at least one SPS PDSCH received by the transceiver; or
a feedback information bit associated with the first process index is set as the feedback information of the dynamic scheduling PDSCH.

14. The device of claim 9 , further comprising a transceiver, wherein
responsive to that a HARQ process index of a dynamic scheduling PDSCH received by the transceiver is a first process index and a HARQ process index corresponding to at least one transmission resource in the plurality of transmission resources is the first process index, the first feedback information codebook comprises feedback information of a dynamic scheduling PDSCH and feedback information corresp
