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

What is claimed is:

1. A method, comprising:
selecting, by a terminal device, a target uplink control channel from a group of uplink control channels comprising a first uplink control channel and a second uplink control channel, wherein the first uplink control channel corresponds to first uplink control information having a first type, and the second uplink control channel corresponds to second uplink control information having a second type, and wherein the first uplink control channel is allocated by a network device using a first preset timing rule that is determined according to the first type of the first uplink control information, and the second uplink control channel is allocated by the network device using a second preset timing rule that is determined according to the second type of the second uplink control information, and selecting the target uplink control channel comprises:
in response to determining that the first uplink control information is control information corresponding to a first-type service, and that a difference between an end moment of the first uplink control channel and an end moment of the second uplink control channel is greater than a first threshold, selecting the target uplink control channel to be an uplink control channel having an earlier end moment of the first uplink control channel and the second uplink control channel; 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; and
wherein 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.

2. The method according to claim 1 , wherein selecting the target uplink control channel further comprises:
in response to determining that the first uplink control information is control information corresponding to the first-type service and that 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, selecting the target uplink control channel to be an uplink control channel having a greater capacity of the first uplink control channel and the second uplink control channel.

3. The method according to claim 1 , wherein:
the first uplink control information is hybrid automatic repeat request-acknowledgement information, and the second uplink control information is first-type channel state information.

4. The method according to claim 3 , wherein the first-type channel state information is periodic channel state information.

5. The method according to claim 1 , wherein before the terminal device sends the target uplink control information on the target uplink control channel, the method further comprises:
receiving, by the terminal device, configuration information, wherein the configuration information indicates that the terminal device is allowed to simultaneously transmit the first uplink control information and the second uplink control information.

6. The method according to claim 1 , wherein:
the first uplink control information is second-type channel state information, and the second uplink control information is first-type channel state information, and wherein the first-type channel state information is periodic channel state information, and the second-type channel state information is low latency channel state information.

7. The method according to claim 1 , wherein:
the first uplink control information is first-type scheduling request information, and the second uplink control information is hybrid automatic repeat request-acknowledgement information, first-type channel state information, or second-type channel state information, and wherein the first-type channel state information is periodic channel state information, the second-type channel state information is low latency channel state information, and the first-type scheduling request information is a scheduling request corresponding to a first-type service.

8. A method, comprising:
selecting, by a network device, a target uplink control channel from a group of uplink control channels comprising a first uplink control channel and a second uplink control channel, wherein the first uplink control channel corresponds to first uplink control information having a first type, and the second uplink control channel corresponds to second uplink control information having a second type, and wherein the first uplink control channel is allocated by the network device using a first preset timing rule that is determined according to the first type of the first uplink control information, and the second uplink control channel is allocated by the network device using a second preset timing rule that is determined according to the second type of the second uplink control information, and selecting the target uplink control channel comprises:
in response to determining that the first uplink control information is control information corresponding to a first-type service, and that a difference between an end moment of the first uplink control channel and an end moment of the second uplink control channel is greater than a first threshold, selecting the target uplink control channel to be an uplink control channel having an earlier end moment of the first uplink control channel and the second uplink control channel; and

receiving, by the network device on the target uplink control channel, target uplink control information sent by a terminal device, wherein the target uplink control information comprises the first uplink control information and the second uplink control information; and
wherein 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.

9. The method according to claim 8 , wherein selecting the target uplink control channel further comprises:
in response to determining that the first uplink control information is control information corresponding to the first-type service and that 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, selecting the target uplink control channel to be an uplink control channel having a greater capacity of the first uplink control channel and the second uplink control channel.

10. An apparatus, comprising:
a non-transitory storage medium including executable instructions; and
a processor;
wherein the executable instructions, when executed by the processor, cause the apparatus to:
select a target uplink control channel from a group of uplink control channels comprising a first uplink control channel and a second uplink control channel, wherein the first uplink control channel corresponds to first uplink control information having a first type, and the second uplink control channel corresponds to second uplink control information having a second type, and wherein the first uplink control channel is allocated by a network device using a first preset timing rule that is determined according to the first type of the first uplink control information, and the second uplink control channel is allocated by the network device using a second preset timing rule that is determined according to the second type of the second uplink control information, and selecting the target uplink control channel comprises:
in response to
