Abstract: The present disclosure relates to a 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE). A method and apparatus in the wireless communication system includes detecting at least one first object including at least one user equipment (UE), transmitting, to a second base station (BS), a first message including sensing information of the at least one first object, receiving, as response to the first message, from the second BS, a second message including sensing information of at least one second object, identifying the at least one UE based on the at least one first object and the at least one second object, estimating a location of the identified at least one UE, determining a beamforming vector based on the estimated location, and transmitting data, to the at least one UE, based on the determined beamforming vector.

Abstract: The present disclosure relates to a method and device for communication by a base station in a wireless communication system supporting multiple reconfigurable intelligent surface (RIS) devices. According to an embodiment A method for operating a base station, the method comprises selecting at least two reference reconfigurable intelligent surface (RIS) devices for estimating a position of a user equipment (UE) from among a plurality of RIS devices, estimating position information about the UE using the selected at least two reference RIS devices, receiving an uplink pilot signal of the UE through the selected at least two reference RIS devices; and estimating a multi-RIS channel for the plurality of RIS devices based on the uplink pilot signal of the UE and the estimated position information about the UE.
