Base station apparatus, mobile station apparatus, and method of assigning subscarriers |
摘要 |
A base station assigns a subcarrier for downlink communications under Orthogonal Frequency Division Multiple Access. Before downlink communications with a mobile station, based on carrier sensing by the mobile station, the base station detects information concerning an available subcarrier from downlink signals using a modulating unit. The information concerning the available subcarrier is stored in a downlink-information sharing unit and is shared among the base station and the adjacent base stations. A downlink subcarrier setting unit sets the available subcarrier for downlink communications.
