MOBILE COMMUNICATION SYSTEM, BASE STATION, MOBILE STATION, AND WIRELESS COMMUNICATION METHOD

摘要

A base station (12) performs communication to and from a mobile station via at least a part of a plurality of radio channels. The base station (12) includes: a channel allocation section (30) for allocating a radio channel having an allocation effective period of two or more frames to the mobile station; and a channel notification section (34) for notifying the mobile station of a radio channel newly allocated by the channel allocation section (30) in response to an expiration of the allocation effective period of the radio channel which has been allocated by the channel allocation section (30). The mobile station uses the radio channel notified from the base station (12) for communicating to and from the base station (12) until an allocation effective period of the new radio channel expires.
