摘要： To effectively improve the reception quality in a pico-base station, while preventing throughput of a macro-base station from significantly deteriorating, a macro-base station (M-BS) is provided with a beam generating section (35) that generates a directional beam to a macro-UE using antenna weights based on a beampattern assigned to the macro-UE existing in a macro-cell having a first coverage area, and a coordination section (36) that determines a beam pattern so that a beam pattern to the macro-UE existing in the macro-cell is a beam pattern that suppresses interference power to a pico-UE existing in a pico-cell, in assigning the beam pattern to the macro-UE existing in the macro-cell during a transmission period assigned to a pico-base station (P-BS) locally forming the pico-cell in the macro-cell.

摘要： A mobile terminal selects a radio base station that is the access point for the mobile terminal in accordance with received-radiowave characteristic values for respective radio base stations. The multiple radio base stations include a macrobase station and multiple picobase stations. Each picobase station includes a load measurement unit adapted for measuring or calculating the communication load index of the picobase station itself; an adjustment-value setting unit adapted for setting an adjustment value that is used by the mobile terminal to change the received-radiowave characteristic value of the picobase station itself, depending on the communication load index; and an adjustment-value signaling unit adapted for signaling the adjustment value set by the adjustment-value setting unit to the mobile terminal.
