Title:
METHOD AND APPARATUS FOR DESIGNING WMMSE BEAMFORMING MATRIX ROBUST TO CHANNEL ERROR FOR MU-MISO SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/249177
Kind Code:
A1
Abstract:
The present invention relates to a method and an apparatus for designing a WMMSE beamforming matrix robust to a channel error for a MU-MISO system. A method by which a base station transmits a signal in a communication system, according to one embodiment of the present invention, may comprise the steps of: receiving, from a mobile station, channel feedback information generated on the basis of a channel between the base station and the mobile station; determining a beamforming matrix that maximizes a weighted sum rate (WSR) by using the channel feedback information; and transmitting a signal to the mobile station on the basis of the beamforming matrix, wherein the channel between the base station and the mobile station may consist of 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 on the basis of the second component corresponding to the quantization error.
