Multi-carrier wireless network using flexible fractional frequency reuse

摘要

A base station for use in a wireless network capable of communicating according to a multi-carrier protocol. The base station communicates with subscriber stations using a first pre-defined set of subcarriers (A1-A5). If the base station determines that no additional subcarriers are available in the first pre-defined set to communicate with a first subscriber station, the base station borrows subcarrier resources by selecting a first subcarrier in a second pre-defined set of subcarriers (B1-B5) used by a first neighboring base station and allocates the first subcarrier in the second pre-defined set to communicate with the first subscriber station.
