Abstract

A control device that functions as a RAN Intelligent Controller (RIC) in an Open-Radio Access Network (O-RAN) identifies a plurality of antennas that are expected to receive a signal transmitted from a terminal device with at least a predetermined power, based on a location of the terminal device, and notifies, among O-RAN Distributed Units (O-DUs) connected to the plurality of antennas, a first O-DU that executes communication processing for the terminal device and a second O-DU that executes communication processing for another terminal device interfered by a signal transmitted from the terminal device of setting information regarding pilot symbols transmitted from the terminal device.
