Patent ID: 8565147

Claim:
A frequency block allocation apparatus which is provided in a wireless base station, performs frequency block allocation using a single carrier frequency division multiple access method so that a terminal sends a wireless signal to the wireless base station, the apparatus comprising: a frequency block manager that stores allocation information which indicates whether or not each frequency block has been allocated to any terminal; an allocation index computation target selector that selects frequency block groups, each consisting of one or more non-allocated frequency blocks from a set of non-allocated frequency blocks, based on the allocation information, wherein the selected groups include those each consisting of continuous non-allocated frequency blocks, and do not include any that consists of non-continuous non-allocated frequency blocks; an allocation index computation unit that computes an allocation index for each target pair of each frequency block group and a terminal, based on channel quality information about the frequency block group with respect to the terminal; and a frequency block allocation unit that determines one of the target pairs to be a frequency block allocation target, in accordance with priority based on the computed allocation indexes.
