BASE STATION, RADIO COMMUNICATION SYSTEM, BAND CONTROL METHOD

摘要

A burst section for transmitting and receiving user data for each of mobile stations owned by a downlink sub-frame and an uplink sub-frame which are defined by the orthogonal frequency division multiplex connection method is divided in a frequency axis direction into a plurality of allocation regions corresponding to the number of sectors. An allocation region for transmitting and receiving user data for each of the mobile stations is allocated to an allocation region corresponding to a sector in which the mobile station exists. When the allocation band required for transmitting the user data in the sector exceeds the communication band of the allocation region, allocation is performed to allocation regions corresponding to other sectors excluding the aforementioned sector.
