Abstract
A wireless control unit transmits to a plurality of analog sections a control signal for performing control so as to cause the plurality of analog sections to transition to a loopback mode, transmits to the plurality of analog sections an observation signal for observing delay times, calculates, for each of the plurality of analog sections, a path delay based on the number of clocks generated from when the observation signal is transmitted to when the observation signal is received, and transmits to the plurality of analog sections a control signal for canceling the loopback mode of the plurality of analog sections. In addition, the wireless control unit transmits a downlink signal at a timing calculated for each of the plurality of analog sections according to the path delay.
