Abstract:
1. A subcarrier allocation apparatus that determines, for each subcarrier, a link to which the subcarrier is allocated, from among links between base stations and terminals, the subcarrier allocation apparatus comprising: a memory that stores allocation patterns of the links for an allocation of the subcarriers to the links; a selector that selects the subcarriers one by one in order; allocation evaluation value calculators that are arranged to correspond to cells of the base stations and that calculate, for each allocation pattern, allocation evaluation values indicating a desirability of allocation in the corresponding cells at a time of the allocation of a subcarrier currently selected by the selector to the links in accordance with the allocation pattern; an adder that adds, for each allocation pattern, the allocation evaluation values calculated by the allocation evaluation value calculators; and a maximum value detector that detects a maximum value from an addition result of the allocation evaluation values added by the adder and that determines an optimal allocation pattern of the subcarrier currently selected by the selector according to an allocation pattern for which the addition result indicates the maximum value, wherein there are n allocation evaluation value calculators that are arranged to correspond to cells of n base stations, and n comprises a natural number that is equal to or greater than 2.
