<p><P>PROBLEM TO BE SOLVED: To provide a mobile wireless communication apparatus capable of reducing the influence of Doppler shift and to provide a wireless communication method and a wireless communication system utilizing the mobile wireless communication apparatus. <P>SOLUTION: The mobile wireless communication apparatus MT1 acquires information of a moving speed and a moving direction from a base station BS1. In a period of transmitting/receiving radio waves through an antenna part 5 of the mobile wireless communication apparatus MT1, the antenna part 5 is oscillated on the basis of the acquired information so that timewise changes in a radio wave propagation distance between the antenna part 5 and the base station BS1 can be suppressed. Since the timewise changes in the propagation distance of radio waves to be transmitted/received to/from the antenna part 5, the influence of Doppler shift can be reduced even when communication is performed during movement. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
