Abstract
In this invention, base stations established in service areas use sector antennas to cover a multiplicity of sector cells. When a communication request arises between a wireless terminal and a sector cell within the sector cell, the base station determines the arrival directions of interference waves on all channels and the arrival direction of the desired waves from the wireless terminal, selects channel in order for which the difference between arrival directions of interference waves and desired waves are closest to 180.degree. and allocates the first channel to satisfy allocation conditions.
