<P>PROBLEM TO BE SOLVED: To secure maximum throughput and number of simultaneous connection users according to a situation, without restricted by the presently allocated frequency bandwidth in radio communication. <P>SOLUTION: A base station 11 and a terminal 21 include a communication function using a shared frequency in a white space, in addition to a dedicated frequency allocated to the radio communication system. When communication traffic to be transmitted between the base station 11 and the terminal 21 includes a first traffic GT with band guarantee given thereto and a second traffic NT without band guarantee, uplink and downlink radio resource determination units 114, 115 allocate the GT to a radio resource DRR of the dedicated frequency and, if the dedicated frequency is usable, allocate the NT (or GT depending on a case) to a radio resource SRR of the shared frequency. <P>COPYRIGHT: (C)2012,JPO&INPIT |
