<P>PROBLEM TO BE SOLVED: To expand a communication distance from a base station to a final terminal in a direction-division duplex communication system. <P>SOLUTION: As for communication between the base station and the terminal in the radio communication system which uses an electromagnetic wave radiated by the base station as a carrier as it is, a radiation electromagnetic field is used for communication between the base station and a repeater station and an induced electromagnetic field is used for communication between the repeater station and a terminal station, where a three-stage constitution is employed which comprise the base station normally allowed to have a large size, the repeater station having a relatively large size, and the terminal station reducible in size. <P>COPYRIGHT: (C)2009,JPO&INPIT |
