<p><P>PROBLEM TO BE SOLVED: To provide a radio communication method, transmitter, receiver and radio communication device with which it is possible to further reduce the power consumption in the reception wait state of the radio communication device and eliminate communication conflict with other communication devices. <P>SOLUTION: A first reception unit 1515 always receives a control frame with a narrow-band channel. According to the control frame, a communication data selection unit 202 controls power save of a second reception unit performing reception with a UWB channel. A communication data generation unit 1520 generates communication time reservation response information by adding information reporting a normal reception to the communication time reservation request received and transmits the information from transmission units 1501-1506 with the narrow-band channel, so that a second reception unit 1514 is set to the operation state only during the time when the UWB communication is performed and use of the time band for performing UWB communication is reported to the radio communication device which has made the communication request and the radio communication device in the transmission-enabled area. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
