Title:
APPARATUS AND METHOD FOR ESTIMATING CHANNEL RELATED TO INTELLIGENT REFLECTING SURFACE IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/219192
Kind Code:
A1
Abstract:
The present disclosure is to estimate a channel in a wireless communication system, and an operating method of a base station may comprise the steps of: receiving reference signals from at least one user equipment (UE); estimating a channel on the basis of the reference signals; performing scheduling for uplink communication; transmitting an uplink grant to the at least one UE on the basis of a result of the scheduling; and receiving uplink data from the at least one UE according to the uplink grant.
