COMMUNICATION CONTROL METHOD, COMMUNICATION SYSTEM, COMMUNICATION CONTROL DEVICE, AND RADIO BASE STATION

摘要

Provided is a communication method in a communication system including a plurality of radio base stations (1) each having an adaptive array antenna and a communication control device (2). The method includes a step of storing in an interference table (23): position information indicating an interference region by adjacent radio base stations (1-1, 1-2); a first weight coefficient for the radio base station (1-1) to direct a beam to the interference region; and a second weight coefficient for the radio base station (1-2) to direct a beam to the interference region, while correlating them to one another. While the radio base station (1-1) is communicating with a terminal (3), the weight coefficients used by the radio base stations (1-1, 1-2) are acquired and compared to the first and the second weight coefficient stored in the interference table (23). According to the comparison result, it is judged whether the terminal (3) is located in the interference region. If yes, the beam generation by the radio base station (1-2) is controlled so as to eliminate interference. Thus, it is possible to perform stable communication without being interfered by the adjacent radio base station.
