Abstract: A method includes: receiving, by a first network control device, CoMP pre-scheduling requests respectively corresponding to at least one edge cell and a first edge cell that is adjacent to the at least one edge cell and that belongs to another CoMP cluster; when determining, based on the CoMP pre-scheduling requests, that the at least one edge cell has a second edge cell meeting a preset condition with the first edge cell, sending an inter-cluster pre-scheduling request to a second network control device; and instructing the second network control device to assign a first coordination cell set including the first edge cell and the second edge cell.

Abstract: A communication method and an apparatus are provided. The method includes: A network device determines, in a first time domain unit, whether data of N to-be-scheduled terminals in a second time domain unit in M cells of the network device is delay-sensitive data; and if the network device determines that data of K to-be-scheduled terminals of the N to-be-scheduled terminals is delay-sensitive data, the K to-be-scheduled terminals are separately located in P cells of the M cells, and a power required for sending the delay-sensitive data in each of the P cells is less than or equal to a preset power threshold corresponding to the cell, the network device sends the data of the K to-be-scheduled terminals in a second time domain unit of the P cells.

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.
