Title:
METHOD AND DEVICE FOR TRANSMITTING SIGNAL IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/250221
Kind Code:
A1
Abstract:
As one embodiment of the present disclosure, a method for operating a terminal in a wireless communication system comprises steps in which: a terminal receives a channel status information-reference signal (CSI-RS) from a base station; feedback is transmitted on the basis of the received CSI-RS; and an intelligent reflecting surface (IRS) reflection matrix is set on the basis of the received CSI-RS. The CSI-RS can be transmitted through an IRS. In addition, the method comprises the steps of: setting a precoder and a combiner on the basis of the received CSI-RS; determining beamforming on the basis of the set precoder and combiner; and receiving a signal from the base station through the IRS on the basis of the determined beamforming.
