COLLABORATIVE SCHEDULING METHOD AND NETWORK DEVICE

摘要

Disclosed are a collaborative scheduling method and a network device, which can improve transmission performance in case in which multiple cells are not strictly synchronized. The method is used for a wireless communications system. A main serving cell and a collaborative cell of a user equipment (UE) in the system collaborate with each other to provide a communications service to the UE. The method comprises: a network device obtaining a phase compensation quantity of a first signal relative to a second signal, the first signal being a physical downlink shared channel (PDSCH) signal transmitted by the collaborative cell to the UE, and the second signal being a physical downlink control channel (PDCCH) signal transmitted by the main serving cell to the UE; and then, the network device controlling the collaborative cell to transmit the first signal obtained after phase precompensation is performed according to the phase compensation quantity, so as to enable the first signal and the second signal obtained after the phase precompensation is performed to be synchronous. The present invention is applicable to the field of communications.
