Document Type and Number:
Japanese Patent JP5766842
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a communication system, a base station device and a server device, capable of reducing interference between a plurality of base station devices in which at least a portion of a radio communication area is overlapped, while suppressing the deterioration of a downlink transmission throughput to a mobile station.SOLUTION: On deciding that the suspension of downward transmission from a base station of an interference source is required in regard to at least one subframe in the radio communication frame of downward transmission to the mobile station, based on interference signal level information in the interfered base station device 20, a server device 40 determines at least one subframe of a transmission suspension target in a radio communication frame, to transmit to a base station device 10 of the interference source. The base station device 10 of the interference source controls to suspend downward transmission in the subframe of the transmission suspension target, based on the subframe information of the transmission suspension target received from the server device 40.
