Abstract:
1. A method for performing weighted processing on a downlink signal, comprising: acquiring a first Channel Impulse Response (CIR) from a Base Station (BS) of a relay communications system to a relay station of a plurality of relay stations of the relay communication system and a second CIR from the relay station to a Mobile Station (MS); determining a pre-coding weight and a relay weight according to the first CIR and the second CIR; and sending the pre-coding weight to the BS and sending the relay weight to the relay station, so that the BS is enabled to perform weighted processing on a downlink signal according to the pre-coding weight to obtain a downlink pre-coding weighted signal and send the downlink pre-coding weighted signal to the relay station, and the relay station is enabled to perform weighted processing on the downlink pre-coding weighted signal received from the BS according to the relay weight to obtain a downlink relay weighted signal and send the downlink relay weighted signal to the MS, wherein the determining the pre-coding weight and the relay weight according to the first CIR and the second CIR comprises:
