Document Type and Number:
WIPO Patent Application WO/2023/224148
Kind Code:
A1
Abstract:
The objective of the present disclosure is to estimate a channel in a wireless communication system, and a base station operating method may comprise the steps of: transmitting configuration information about at least one downlink reference signal; transmitting the at least one downlink reference signal; transmitting configuration information about an uplink reference signal to at least one user equipment (UE); receiving channel information from a reflecting intelligent surface (RIS); transmitting control information notifying of a scheduling result for transmitting downlink data to the at least one UE; and transmitting the downlink data to the at least one UE according to the scheduling result.
