Radio frequency channel management method, apparatus, and related device
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.
