1. A communication system using wireless signals for communications including downlink signals to and uplink signals from mobile stations, comprising:

  • a plurality of base stations to communicate with said mobile stations using said downlink signals and said uplink signals with frequency hopping sequences, andhopping sequence control means for controlling said frequency hopping sequences at two or more adjacent ones of said base stations whereby mobile stations in a region between said two or more adjacent ones of said base stations communicate with coordinated orthogonal frequency hopping sequences,wherein,each of said base stations to operate with three or more sector,said hopping sequence control means to control two or more adjacent ones of said sectors for adjacent ones of said base stations, respectively, to have said coordinated orthogonal frequency hopping sequences, anda virtual cell is formed by at least three adjacent sectors of at least three adjacent base stations, respectively, wherein said coordinated orthogonal frequency hopping sequences is used for said at least three adjacent sectors.
