COMMUNICATION SYSTEM

摘要

A communication system (1) includes a base station (2), a mobile station (3) capable of relative movement with respect to the base station (2), and a relay station (4) relaying radio communication between the base station (2) and the mobile station (3). The relay station (4) can move relatively to the base station (2) and to the mobile station (3). When the base station (2) and the mobile station (3) perform radio communication, the relay station (4) can be moved to an appropriate position for relaying the communication. As compared to the conventional technique in which the relay station (4) is fixed to a certain position, it is possible to prevent lowing of the reception radio intensity more effectively between the base station (2) and the mobile station (3). Thus, even when the mobile station (3) moves with respect to the base station (2), it is possible to assure preferable radio communication between these stations (2, 3).
