Abstract

A communication device includes a first carrier and a second carrier. In a radio frequency channel management process, the communication device obtains a downlink sub-frame, and determines a target sub-frame in the downlink sub-frame, where both the first carrier and the second carrier allow shutting down a target radio frequency channel of the communication device in a time period corresponding to the target sub-frame. The communication device shuts down the target radio frequency channel in the time period corresponding to the target sub-frame. In this way, an energy-saving effect of the communication device is achieved by performing shutdown control on a radio frequency channel in a time period corresponding to a sub-frame granularity without affecting data communication between the communication device and another device based on each carrier.

Claims (34)

1 . A radio frequency channel management method performed by a communication device comprising a first carrier and a second carrier, the method comprising:

obtaining a downlink sub-frame of the communication device;

determining a target sub-frame in the downlink sub-frame, wherein both the first carrier and the second carrier allow shutting down a target radio frequency channel of the communication device in a time period corresponding to the target sub-frame; and

shutting down the target radio frequency channel in the time period corresponding to the target sub-frame when traffic corresponding to a data signal carried by the second carrier in a preset time period is large-packet traffic or when traffic corresponding to a data signal carried by the second carrier in a preset time period is large-packet traffic.

2 . The method according to claim 1 , further comprising:

obtaining a first radio frequency channel that can be shut down and that corresponds to the first carrier; and

determining the target radio frequency channel in the first radio frequency channel.

3 . The method according to claim 1 , wherein the step of determining the target sub- frame in the downlink sub-frame comprises:

determining the target sub-frame based on traffic load corresponding to the first carrier and traffic load corresponding to the second carrier.

4 . The method according to claim 1 , wherein the step of shutting down the target radio frequency channel of the communication device comprises:

setting a weight of transmit power of the target radio frequency channel to zero in the time period corresponding to the target sub-frame.

5 . The method according to claim 1 , wherein the first carrier and the second carrier are of different types.

6 . A radio frequency channel management method performed by a communication device comprising a first carrier and a second carrier, the method comprising:

obtaining a downlink sub-frame of the communication device;

determining a target sub-frame in the downlink sub-frame, wherein both the first carrier and the second carrier allow shutting down a target radio frequency channel of the communication device in a time period corresponding to the target sub-frame; and

skipping shutting down the target radio frequency channel in the time period corresponding to the target sub-frame when traffic corresponding to a data signal carried by the second carrier in a preset time period is large-packet traffic.

7 . The method according to claim 6 , wherein the communication device communicates with user equipment based on the second carrier, and the method further comprises:

skipping shutting down the target radio frequency channel in the time period corresponding to the target sub-frame when a communication distance between the communication device and the user equipment exceeds a preset distance.

8 . A communication device comprising:

a first carrier;

a second carrier;

a processor; and

a memory storing executable instructions that, when executed by the processor, cause the communication device to perform operations of:

obtaining a downlink sub-frame of the communication device;

determining a target sub-frame in the downlink sub-frame, wherein both the first carrier and the second carrier allow shutting down a target radio frequency channel of the communication device in a time period corresponding to the target sub-frame; and

shutting down the target radio frequency channel in the time period corresponding to the target sub-frame when traffic corresponding to a data signal carried by the second carrier in a preset time period is large-packet traffic or when traffic corresponding to a data signal carried by the second carrier in a preset time period is large-packet traffic.

9 . The apparatus according to claim 8 , wherein the communication device is caused to perform operations of:

obtaining a first radio frequency channel that can be shut down and that corresponds to the first carrier; and

determining the target radio frequency channel in the first radio frequency channel.

10 . The apparatus according to claim 8 , wherein the operation of determining the target sub-frame in the downlink sub-frame comprises:

determining the target sub-frame based on traffic load corresponding to the first carrier and traffic load corresponding to the second carrier.

11 . The apparatus according to claim 8 , wherein the operation of shutting down the target radio frequency channel of the communication device comprises:

setting a weight of transmit power of the target radio frequency channel to zero in the time period corresponding to the target sub-frame.

12 . The apparatus according to claim 8 , wherein the first carrier and the second carrier are of different types.
