<P>PROBLEM TO BE SOLVED: To provide a radio communication terminal device, a radio communication system, and a radio communication method which allow a propagation delay time to be measured with a high precision by selecting a frequency band signal for measurement of the propagation delay time in accordance with a reception state of a prescribed frequency band signal. <P>SOLUTION: When performing processing of specifying a present position, a propagation delay time measurement part 13 determines which of a pilot signal in the band of 800 MHz and a signal in the band of 2 GHz should be used to measure the propagation delay time, on the basis of a reception signal intensity. <P>COPYRIGHT: (C)2007,JPO&INPIT |
