Abstract

The present disclosure relates to uplink control information sending methods, uplink control information receiving methods, apparatus, and systems. One example method includes receiving, by a terminal device, channel indication information from an access network device on a physical control channel, determining a channel resource set of N channel resource sets that matches a size of uplink control information (UCI) as a first channel resource set, determining a first channel resource from the first channel resource set according to the channel indication information, and sending the UCI to the access network device on the first channel resource.

First claim

What is claimed is:

1. A non-transitory computer readable storage medium comprising instructions which, when executed by one or more processors, cause a terminal device to perform operations comprising:
receiving configuration information from an access network device, wherein the configuration information indicates N channel resource sets, and N is a positive integer greater than or equal to 2;
receiving channel indication information from the access network device on a physical control channel;
determining a channel resource set of the N channel resource sets as a first channel resource set;
determining a first channel resource from the first channel resource set according to the channel indication information; and
sending uplink control information (UCI) to the access network device on the first channel resource.

2. The non-transitory computer readable storage medium according to claim 1 , wherein the operations further comprise:
determining the channel resource set of the N channel resource sets as the first channel resource set according to a quantity of bits of the UCI.

3. The non-transitory computer readable storage medium according to claim 2 , wherein the first channel resource set is the i th channel resource set in the N channel resource sets, wherein R a meets R i−1 <R a ≤R i , 2≤i≤4, wherein R a is equal to the quantity of bits of the UCI, and wherein R is a channel capacity corresponding to each channel resource in the i th channel resource set.

4. The non-transitory computer readable storage medium according to claim 1 , wherein quantities of channel resources comprised in each channel resource set of the N channel resource sets are the same.

5. The non-transitory computer readable storage medium according to claim 1 , wherein at least one channel resource set of the N channel resource sets comprises at least two channel resources with different physical uplink control channel (PUCCH) formats.

6. The non-transitory computer readable storage medium according to claim 1 , wherein the UCI comprises channel state information (CSI).

7. The non-transitory computer readable storage medium according to claim 1 , wherein the UCI is CSI or hybrid automatic repeat request-acknowledgment (HARQ-ACK) information.

8. The non-transitory computer readable storage medium according to claim 1 , wherein at least one of the N channel resource sets comprises at least two channel resources.

9. The non-transitory computer readable storage medium according to claim 1 , wherein the UCI comprises CSI and HARQ-ACK information.

10. A non-transitory computer readable storage medium comprising instructions which, when executed by one or more processors, cause an access network device to perform operations comprising:
sending configuration information to a terminal device, wherein the configuration information indicates N channel resource sets, and N is a positive integer greater than or equal to 2;
sending channel indication information to the terminal device on a physical control channel, wherein the channel indication information indicates a first channel resource in a first channel resource set, wherein the first channel resource set is one channel resource set in the N channel resource sets; and
receiving uplink control information (UCI) from the terminal device on the first channel resource.

11. The non-transitory computer readable storage medium according to claim 10 , wherein the first channel resource set is in accordance with a quantity of bits of the UCI.

12. The non-transitory computer readable storage medium according to claim 11 , wherein the first channel resource set is the i th channel resource set in the N channel resource sets, wherein R a meets R i−1 <R a ≤R i , 2≤i≤4, wherein Ra is equal to the quantity of bits of the UCI, and wherein R i is a channel capacity corresponding to each channel resource in the i th channel resource set.

13. The non-transitory computer readable storage medium according to claim 10 , wherein quantities of channel resources comprised in each channel resource set of the N channel resource sets are the same.

14. The non-transitory computer readable storage medium according to claim 10 , wherein at least one channel resource set of the N channel resource sets comprises at least two channel resources with different physical uplink control channel (PUCCH) formats.

15. The non-transitory computer readable storage medium according to claim 10 , wherein the UCI comprises channel state information (CSI).

16. The non-transitory computer readable storage medium according to claim 10 , wherein the UCI is CSI or hybrid automatic repeat request-acknowledgment (HARQ-ACK) information.

17. The non-transitory computer readable storage medium according to claim 10 , wherein at least one of the N channel resource sets comprises at least two channel resources.

18. The non-transitory computer readable storage medium according to claim 10 , wherein the UCI comprises CSI and HARQ-ACK information.

19. An apparatus, comprising:
at least one processor; and
a non-transitory computer readable storage medium coupled with the at least one processor and storing programming instructions which, when executed by the at least one processor, cause the apparatus to:
receive configuration information from an access network device, wherein the configuration information indicates N channel resource sets, and N is a positive integer greater than or equal to 2;
receive channel indication information from the access network device on a physical control channel;
determine a channel resource set of the N channel resource sets as a first channel resource set;
determine a first channel resource from the first channel resource set according to the channel indication information; and
send uplink control information (UCI) to the access network device on the first channel resource.

20. The apparatus according to claim 15 , wherein the programing instructions which, when executed by the at least one processor, cause the apparatus to:
determine the channel resource set of the N channel resource sets as the first channel resource set according to a quantity of bits of the UCI.

21. The apparatus according to claim 20 , wherein the first channel resource set is the i th channel resource set in the N channel resource sets, wherein R a meets R i−1 <R a ≤R i , 2≤i≤4, wherein R a is equal to the quantity of bits of the UCI, and wherein R i is a channel capacity corresponding to each channel resource in the i th channel resource set.

22. The apparatus according to claim 19 , wherein quantities of channel resources comprised in each channel resource set of the N channel resource sets are the same.

23. The apparatus according to claim 19 , wherein at least one channel resource set of the N channel resource sets comprises at least two channel resources with different physical uplink control channel (PUCCH) formats.
