BASE STATION, MOBILE COMMUNICATION SYSTEM AND CHANNEL ASSIGNMENT METHOD

摘要

A base station communicates with plural terminals with using plural frequency channels having different bandwidths. The base station includes: a carrier-sensing unit that carrier-senses the plurality of frequency channels; a first calculating unit that estimates whether the frequency channels are used or not, and calculates first priorities of respective frequency channels; a second calculating unit that calculates a plurality of second priorities of respective communication frequency channels having a bandwidth to be used in communication with a terminal based on the first priorities of the communication frequency channels and the first priorities of reference frequency channels having a bandwidth wider than the communication frequency channels have; a third calculating unit that calculates an assignment order of the communication frequency channels based on the plural second priorities; and a channel assigning unit that assigns a communication frequency channel to the communication in accordance with the assignment order.
