Abstract
In a wireless communication system, a base station device communicates with a terminal device via any relay device (reconfigurable intelligent surface). The base station device stores a CSI when passing through the relay device in association with the object arrangement information. When the current object arrangement information is similar to the stored past object arrangement information, the base station device determines a relay device to be used at the present time on the basis of each CSI stored in association with the past object arrangement information. According to this, it is possible to reduce overhead for acquiring the CSI, and simultaneously execute the use determination of the plurality of reconfigurable intelligent surfaces, by re-using the CSI.
