Abstract
A method, a system, and an apparatus for improving throughput performance of an SDMA system are disclosed herein. The method includes BTS receiving feedback information sent by a UE, where the feedback information comprises an ID of a preferred beam of the UE in a pre-coding codebook, information related to a channel vector modulus value, and information about phase difference between a channel vector and the preferred beam of the UE, and the BTS using a set estimation algorithm to estimate sum throughputs supported by a current SDMA system in each sending mode according to the received feedback information and information about space correlation between multiple antennas of the BTS, selecting a maximum sum throughput among the estimated sum throughputs, and using the sending mode corresponding to this sum throughput to send data. The method, system, and apparatus provided herein improve transmitting performance of the SDMA system.
