WIRELESS COMMUNICATION SYSTEM.BASE STATION.MOBILE STATION

摘要

PROBLEM TO BE SOLVED: To provide a wireless communication system adopting the space division multiple access system (SDMA) that avoids a scale of base stations from being enlarged. SOLUTION: A mobile station in the wireless communication system of this invention is provided with a radio wave arrival direction measurement means that measures the arrival direction of a radio wave sent from the based station, an attitude measurement means the measures deviation in the attitude of the mobile station from the coordinated with respect to the earth, and a delay time measurement means that obtains the distance between the mobile station and the base station. The mobile station obtains a vector that takes the base station as a start point and the mobile station as an end point, informs the base station about this vector and the base station controls the direction of the directivity directed to the mobile station.
