    摘要: The present invention relates to the field of communications, and provides a communication method using spatial division multiple access (SDMA), to optimize an existing spatial division multiplexing mechanism. The method comprises: for each channel including a service channel and a control channel, according to a service information amount and/or a control information amount of the channel and a decision threshold corresponding to the channel, determining whether to activate SDMA for the channel; according to a decision result for a remote radio unit (RRU) to which each user belongs, allocating resources in an SDMA manner for the channel with the SDMA activated, and sending data of each user on the channel only on the RRU to which the user belongs; for a channel with the SDMA not activated, sending all data on the channel on all RRUs. The present invention is applicable to the spatial division multiplexing of various physical channels and physical signals specified by the standards of LTE and LTE-A systems, and can further improve utilization of resources in the system, the throughput of the system, and the data transmission rate.
