An uplink signal weighted processing method, an uplink signal weighted processing device, and a communication system are provided. The method includes: acquiring a first channel impulse response from a Mobile Station (MS) to a relay station and a second channel impulse response from the relay station to a Base Station (BS); determining a relay weight and a demodulation weight according to the first channel impulse response and the second channel impulse response; sending the relay weight and the demodulation weight respectively to the relay station and the BS, so as to enable the relay station to perform weighted processing on an MS uplink signal received by the relay station according to the relay weight to obtain an uplink relay weighted signal and send the uplink relay weighted signal to the BS, and enable the BS to perform demodulation weighted processing on the uplink relay weighted signal received by the BS according to the demodulation weight to obtain an uplink estimation signal corresponding to the MS uplink signal. Therefore, the uplink signal is respectively optimized at a relay station and a BS, thereby facilitating the optimization of the network capacity and the improvement of the communication quality.
Description
technical field [0001] The present invention relates to the technical field of communication, in particular to an uplink signal weighting processing method, device and communication system. Background technique [0002] The next generation network (Next Generation Network, NGN for short) puts forward higher requirements on spectrum efficiency and power efficiency. Compared with the traditional cellular network, the relay mobile network can effectively improve the network coverage quality, and provides a cost-effective solution for realizing broadband wireless access in the high frequency band. [0003] A repeater mobile network can be composed of multiple repeaters to form a virtual array to work together. In a relay mobile network, a mobile station (Mobile Station, MS for short) can access a wireless network through a base station (Base Station, BS for short) under the cooperation of multiple repeaters. In the relay mobile network, the existing technology usually optimize...
