Abstract:
1. A wireless communication device configured to perform an intermittent receiving operation during standby, comprising: a frame detection monitoring unit configured to monitor detection of a frame during a receiving operation in the intermittent receiving operation; a timer unit configured to extend a period of the receiving operation when receiving a notice of detection of the frame from the frame detection monitoring unit, and to extend the period of the receiving operation again when receiving again the notice of detection of the frame from the frame detection monitoring unit during an extended period of the receiving operation; a physical layer processing unit configured to receive a received signal and detect the frame from the received signal; a transmission/reception managing unit configured to control the timer unit, the frame detection monitoring unit and the physical layer processing unit, and to manage transmission and reception; and a power/clock managing unit configured to, based on control by the timer unit, supply power and a clock to the frame detection monitoring unit, the physical layer processing unit and the transmission/reception managing unit during the period of the receiving operation, and to stop supplying at least one of the power and the clock to the frame detection monitoring unit, the physical layer processing unit and the transmission/reception managing unit during a sleep period other than the period of the receiving operation in the intermittent receiving operation, wherein the frame detection monitoring unit monitors the detection of the frame by the physical layer processing unit; and wherein the frame detection monitoring unit, the physical layer processing unit and the transmission/reception managing unit operate based on the clock.
