Title:
BASE STATION SERVER COMMUNICATING WITH RIS-EQUIPPED VEHICLE, VEHICULAR WIRELESS COMMUNICATION SERVICE COVERAGE IMPROVEMENT SYSTEM COMRPISING SAME, AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/249240
Kind Code:
A1
Abstract:
The present invention relates to a vehicular wireless communication service coverage improvement system comprising: at least one reconfigurable intelligent surface (RIS)-equipped vehicle having an RIS device and a single reception antenna so as to act as an RIS controller; and a base station server for estimating a reception signal by applying a multi-RIS environment channel model in order to support downlink data communication from a base station to the vehicle. Therefore, a communication blockage problem caused by an obstacle in a V2X communication environment can be overcome.
