<P>PROBLEM TO BE SOLVED: To reduce interference by an adjacent PRU to an anchor channel by dividing the frequency domain of a PRU assigned to anchor and extra channels, and to improve stability in communication. <P>SOLUTION: A base station 120 uses an OFDMA system to communicate with one or a plurality of terminal devices 110 by radio. The base station has a channel allocation section 220 for allocating an extra channel 182 used for data communication and an anchor channel 180 including a map indicating the position of a PRU 170 to which the extra channel is allocated to the PRU. The channel allocation section allocates the anchor channel to the PRU of a prescribed frequency domain 190, and allocates the extra channel to the PRU of a frequency 192 except the prescribed frequency domain. <P>COPYRIGHT: (C)2010,JPO&INPIT |
