Abstract

A sending method includes: determining, by a terminal device, a target uplink control channel in a first uplink control channel and a second uplink control channel, where the first uplink control channel corresponds to first uplink control information and the second uplink control channel corresponds to second uplink control information; and sending, by the terminal device, target uplink control information on the target uplink control channel, where the target uplink control information includes the first uplink control information and the second uplink control information.

First claim

1 .- 19 . (canceled)

20 . A method, comprising:
determining, by a terminal device, a target uplink control channel from a first uplink control channel and a second uplink control channel, wherein the first uplink control channel corresponds to first uplink control information, and the second uplink control channel corresponds to second uplink control information; and sending, by the terminal device, target uplink control information on the target uplink control channel, wherein the target uplink control information comprises the first uplink control information and the second uplink control information.

21 . The method according to claim 20 , wherein determining, by the terminal device, the target uplink control channel from the first uplink control channel and the second uplink control channel comprises:
determining, by the terminal device, the target uplink control channel from the first uplink control channel and the second uplink control channel according to a capacity of the first uplink control channel and a capacity of the second uplink control channel, wherein the target uplink control channel is an uplink control channel having a greater capacity of the first uplink control channel and the second uplink control channel.

22 . The method according to claim 20 , wherein:
the determining, by the terminal device, the target uplink control channel from the first uplink control channel and the second uplink control channel comprises determining, by the terminal device, the target uplink control channel according to a service type corresponding to the first uplink control information, an end moment of the first uplink control channel, and an end moment of the second uplink control channel; determining the target uplink control channel comprises:
when the first uplink control information is control information corresponding to a first-type service and the end moment of the first uplink control channel is the same as the end moment of the second uplink control channel, determining the target uplink control channel as an uplink control channel having a greater capacity of the first uplink control channel and the second uplink control channel;
when the first uplink control information is control information corresponding to the first-type service and a difference between the end moment of the first uplink control channel and the end moment of the second uplink control channel is less than or equal to a first threshold, determining the target uplink control channel as an uplink control channel having a greater capacity of the first uplink control channel and the second uplink control channel;
when the first uplink control information is control information corresponding to the first-type service and the end moment of the first uplink control channel is different from the end moment of the second uplink control channel, determining the target uplink control channel as an uplink control channel having an earlier end moment of the first uplink control channel and the second uplink control channel; or
when the first uplink control information is control information corresponding to the first-type service, and the difference between the end moment of the first uplink control channel and the end moment of the second uplink control channel is greater than the first threshold, determining the target uplink control channel as an uplink control channel having an earlier end moment of the first uplink control channel and the second uplink control channel; and
a service latency of the first-type service is less than or equal to a preset latency threshold, or a service bit error rate of the first-type service is less than or equal to a preset bit error rate threshold.

23 . The method according to claim 20 , wherein determining, by the terminal device, the target uplink control channel from the first uplink control channel and the second uplink control channel comprises determining, by the terminal device, the target uplink control channel from the first uplink control channel and the second uplink control channel according to a service type corresponding to the first uplink control information, a capacity of the first uplink control channel, and a capacity of the second uplink control channel, and wherein:
when the first uplink control information is control information corresponding to a first-type service, the target uplink control channel is an uplink control channel having a greater capacity of the first uplink control channel and the second uplink control channel, and a service latency of the first-type service is less than or equal to a preset latency threshold or a service bit error rate of the first-type service is less than or equal to a preset bit error rate threshold.

24 . The method according to claim 20 , wherein the first uplink control channel and the second uplink control channel overlap in time, and determining, by the terminal device, the target uplink control channel from the first uplink control channel and the second uplink control channel comprises determining, by the terminal device, the target uplink control channel according to an end moment of the first uplink control channel and an end moment of the second uplink control channel, wherein:
the target uplink control channel is an uplink control channel having an earlier end moment of the first uplink control channel and the second uplink control channel; when a difference between the end moment of the first uplink control channel and the end moment of the second uplink control channel is greater than a first threshold, the target uplink control channel is an uplink control channel having an earlier end moment of the first uplink control channel and the second uplink control channel; or when the difference between the end moment of the first uplink control channel and the end moment of the second uplink control channel is less than or equal to the first threshold, the target uplink control channel is the first uplink control channel or the second uplink control channel.

25 . The method according to claim 20 , wherein the first uplink control channel and the second uplink control channel overlap in time, wherein determining, by the terminal device, the target uplink control channel in the first uplink control channel and the second uplink control channel comprises determining, by the terminal device, the target uplink control channel according to a start moment of the first uplink control channel and a start moment of the second uplink control channel or according to an end moment of the first uplink control channel and an end moment of the second uplink control channel, and wherein:
when the end moment of the second uplink control channel is earlier than the end moment of the first uplink control channel and a difference between the start moment of the second uplink control channel and the start moment of the first uplink control channel is less than a second threshold, the target uplink control channel is the second uplink control channel; when the end moment of the second uplink control channel is later than the end moment of the first uplink control channel, the target uplink control channel is the first uplink control channel; or when the end moment of the second uplink control channel is earlier than the end moment of the first uplink control channel and the difference between the start moment of the second uplink control channel and the start moment of the first uplink control channel is greater than or equal to the second threshold, the target uplink control channel is the first uplink control channel.

26 . The method according to claim 20 , wherein:
