COMMUNICATION APPARATUS AND COMMUNICATION METHOD

摘要

A communication apparatus according to an embodiment of the invention comprises: a single communication unit that operates in a first mode corresponding to short distance radio communications or in a second mode corresponding to radio communications at distances longer than the communication distances of the short distance radio communications; and a control unit that causes radio transmissions or receptions in the first or second mode to be intermittently executed, causes radio receptions in the second mode to be intermittently executed at intervals based on reported information that is repeatedly reported by an external apparatus at predetermined intervals, and that causes radio transmissions or receptions in the first mode to be intermittently executed in synchronization with the execution timing of the second mode while no radio receptions in the second mode are being performed.
