A non-transitory computer-readable storage medium that stores a program for causing a computer included in a processing device, which functions as an O-RAN Distributed Unit (O-DU) connected to one or more antennas to perform radio communication with a terminal device in an Open-Radio Access Network (O-RAN), to:
- receive setting information regarding pilot symbols transmitted from the terminal device from a control device that functions as a RAN Intelligent Controller (RIC);
- estimate a transmission path between the terminal device and at least a portion of the one or more antennas based on the received setting information;
- and
- execute communication processing for a terminal device other than the terminal device by using a result of the transmission path estimation.
