Abstract
A sleep length calculation unitof a terminal calculates a sleep length based on what is contained in a PLCP header of a frame, and sets the calculated length on a timer. An address detection unitof the terminal detects a destination address from inside a MAC header of the frame to see if this frame is destined for another terminal. If the frame is found destined for another terminal, then this terminal gives a power supply unitan instruction to start sleeping while causing the timerto start counting time. When the sleep length is found to have elapsed on the timer, the terminal gives the power supply unitan instruction to stop sleeping. If what is contained in the PLCP header or MAC header is not deemed reliable, then a sleep inhibit determination unitinhibits the power supply unitfrom going to sleep. The structure allows a wireless communication system to effect a transition into power-saving mode upon acquiring necessary information, without making changes to existing standards.
