Zusammenfassung:A station side device includes a first requesting unit that requests a counterpart communication device to perform a power saving operation of alternately performing execution and suspension of communication at preset time intervals; a phase specifying unit that specifies a first phase of the power saving operation performed by the counterpart communication device and a second phase corresponding to the first phase in the power saving operation of the station side device, based on communication performed with the counterpart communication device; a time-difference calculating unit that calculates a difference between the first phase and the second phase; and a second requesting unit that requests again the counterpart communication device to perform the power saving operation based on the calculated difference.
