Method and apparatus for designing wmmse beamforming matrix robust to channel errors in mu-miso systems

Abstract

The present invention relates to a method and an apparatus for designing a WMMSE beamforming matrix robust to channel errors for MU-MISO systems. A method for transmitting signals from a base station in a communication system according to an embodiment of the present invention may include the steps of: receiving, from a mobile station, channel feedback information generated based on a channel between the base station and the mobile station; determining a beamforming matrix that maximizes the weighted sum rate (WSR) using the channel feedback information; and transmitting a signal to the mobile station based on the beamforming matrix, wherein the channel between the base station and the mobile station may consist a first component corresponding to the channel feedback information and a second component corresponding to a quantization error, and the beamforming matrix may be determined based on the second component corresponding to the quantization error.
