Radiocommunication system, base station, mobile station and radiocommunication method

摘要

RADIOCOMMUNICATION SYSTEM, BASE STATION, MOBILE STATION AND RADIOCOMMUNICATION METHOD. In a radio communication system, which includes a plurality of base stations and a plurality of mobile stations, a base station includes a receive distribution difference reporting unit which measures a receive distribution difference of reference signals transmitted by adjacent base stations, and reports the difference in reception distribution to one or more base stations. A base station has a transmission distribution difference computation unit, which computes a reference signal transmission distribution difference between the base station and adjacent base stations, based on the receiving distribution direction, and a transmission distribution difference information reporting unit, which reports the transmission distribution difference to the mobile station. The mobile station further includes a cell search unit which performs cell search within a limited cell search scope based on the transmission distribution direction transmitted by the base station.
