Abstract:
1. A wireless communication device capable of transmitting and receiving frames by occupying a radio channel for a certain time period, the device comprising: a demodulation unit that demodulates a frame received through the radio channel and outputs the demodulated frame as a received frame; an analyzing unit that operates to: a storage unit that stores a source address included in the received frame when the analyzing unit determines that the received frame includes the suspension signal; a determination unit that determines whether the source address included in the received frame is previously stored in the storage unit when the analyzing unit determines that the received frame includes the destination address that is different from the address assigned to the device; and a power controlling unit that suspends at least a part of a power supply to the demodulation unit and the analyzing unit for a remaining time of the time period for occupying the radio channel, the time period being described in the MAC header, when the determination unit determines that the source address included in the received frame is not previously stored in the storage unit.
