Abstract

Embodiments of the present invention provide an uplink control information sending method, an uplink control information receiving method, an apparatus, and a system. The method includes: receiving, by a terminal device, channel indication information from an access network device on a physical control channel; determining the channel resource set that is of N channel resource sets and that matches a type or a size of the UCI as a first channel resource set; determining a channel resource that is in the first channel resource set and that is indicated by the channel indication information; and sending uplink control information UCI to the access network device on the channel resource. A quantity of bits that need to be added to the channel indication information in the embodiments of the present invention is less than that in the prior art.

First claim

determining, by the terminal device, a channel resource set of the N channel resource sets as a first channel resource set;
determining, by the terminal device, a channel resource from the first channel resource set according to the channel indication information; and
sending, by the terminal device, uplink control information (UCI) to the access network device on the determined channel resource.

2. The method according to claim 1 , further comprising:
determining, by the terminal device, 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 method according to claim 2 , wherein the first channel resource set is the i th channel resource set in the N channel resource sets, and wherein R a meets R i-1 <R a ≤R i , 2≤i≤4, R a is equal to the quantity of bits of the UCI, R i is a channel capacity corresponding to the i th channel resource set, and R i-1 is a channel capacity corresponding to the (i−1) th channel resource set.

4. The method 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 method according to claim 1 , wherein at least one of the N channel resource sets comprises at least two channel resources corresponding to different physical uplink control channel (PUCCH) formats.

6. The method according to claim 1 , wherein at least one of the N channel resource sets comprises at least two channel resources.

7. The method according to claim 1 , wherein the UCI comprises channel state information (CSI).

8. The method according to claim 1 , wherein the UCI comprises CSI and hybrid automatic repeat request-acknowledgment (HARQ-ACK) information.

9. The method according to claim 1 , wherein the UCI is HARQ-ACK information or CSI.

10. A method, comprising:
sending, by an access network device, 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, by the access network device, channel indication information to the terminal device on a physical control channel, wherein the channel indication information indicates a channel resource of a first channel resource set, wherein the first channel resource set is one channel resource set in the N channel resource sets; and
receiving, by the access network device, uplink control information (UCI) from the terminal device on the channel resource.

11. The method according to claim 10 , wherein the first channel resource set is in accordance with a quantity of bits of the UCI.

12. The method according to claim 10 , wherein the first channel resource set is the i th channel resource set in the N channel resource sets, and wherein R a meets R i-1 <R a ≤R i , 2≤i≤4, R a is equal to a quantity of bits of the UCI, R i is a channel capacity corresponding to the i th channel resource set, and R i-1 is a channel capacity corresponding to the (i−1) th channel resource set.

13. The method 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 method according to claim 10 , wherein at least one of the N channel resource sets comprises at least two channel resources corresponding to different physical uplink control channel (PUCCH) formats.

15. The method according to claim 10 , wherein at least one of the N channel resource sets comprises at least two channel resources.

16. The method according to claim 10 , wherein the UCI comprises channel state information (CSI).

17. The method according to claim 10 , wherein the UCI comprises CSI and hybrid automatic repeat request-acknowledgment (HARQ-ACK) information.
