摘要： A method and a device for feeding back and receiving downlink channel information are disclosed, whereby spectrum utilization ratio of downlink channel information feedback is enhanced. According to the present invention, a wireless terminal superposes an uplink user information sequence with spectrum-spread downlink channel information before transmission. A network side de-spreads a received signal before estimating the downlink channel information, and then detects the user information sequence after subtracting the estimated downlink channel information from the received signal. An orthogonal code can be employed to spread the spectrum of the downlink channel information. The wireless terminal and base station use a plurality of antennas for transmission and reception.

摘要： 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.
