ABSTRACT:
Provided is a radio communication system for ultra wideband (UWB) impulse communications and a radio communication apparatus and method thereof. The present patent provides a radio communication system that can minimize power consumption by eliminating a need for carrier detection and sharing transmission/reception time information in UWB impulse communications. The system includes a network coordinator; and one or more devices communicating on a superframe basis in subordination to the network coordinator. The devices perform data transmission/reception in predetermined time slots and then they are inactivated to thereby reduce power consumption.
