FREQUENCY ALLOCATION METHOD IN WIRELESS BASE STATION APPARATUS AND WIRELESS BASE STATION APPARATUS

摘要

A frequency allocation method in a base station communicating wirelessly with a terminal, for dividing a cell into six areas in a clockwise direction, and allocating a frequency to each of the divided sectors, including: dividing the cell into an outer circle and an inner circle; allocating to a first terminal positioned in the outer circle of the sector, a frequency different from a frequency allocated to a second terminal positioned in an adjacent sector of the same cell, and the frequency different from a frequency allocated to a third terminal positioned in the outer circle of an adjacent sector of the adjacent cell; and allocating the frequency allocated to the first terminal to fourth and fifth terminal positioned in the inner circle of two sectors respectively arranged two sectors away from the sector in which the first terminal is positioned.
