WIRELESS COMMUNICATION SYSTEM, WIRELESS COMMUNICATION METHOD, AND WIRELESS COMMUNICATION CONTROL DEVICE

WIPO Patent Application WO/2024/023912

A1

The present disclosure relates to a wireless communication system, a wireless communication method, and a wireless communication control device. This wireless communication system comprises a base station, an RIS device that reflects a radio wave from the base station to a terminal device, and a control device that controls the RIS device. The control device is configured to execute processing for estimating wireless quality within an area in advance, processing for receiving positioning information from the terminal device, processing for performing wake-up determination that determines whether or not the RIS device is required to be activated, and activation processing for transmitting, when it is determined that the RIS device is required to be activated, an RIS parameter signal and a wake-up signal for instructing the activation to the RIS device. The RIS device is configured to execute processing for activating the RIS device when the wake-up signal is received and processing for carrying out reflection control for the radio wave at a reflecting portion of the RIS device on the basis of the RIS parameter signal.
