Abstract

A data transmitting/receiving method capable of effectively suppressing power consumption includes: establishing synchronization between a master device and a slave device based on predetermined synchronization information that is transmitted from the master device or the slave device; setting a contention access period (CAP) between the master device and the slave device at predetermined timing based on the established synchronization; starting data transmission/reception between the master device and the slave device within the CAP; and extending the data transmission/reception even after the CAP in a case where the data transmission/reception does not end within the CAP.
