Document Type and Number:
Japanese Patent JP6549023
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve the throughput of a radio base station and a radio terminal, and the throughput of an entire system in a dense wireless LAN environment.SOLUTION: A radio communication system comprises a plurality of radio base stations for performing radio communication with respective subordinate radio terminals, and a centralized control station for controlling a parameter used for communication control of each radio base station according to environment information and capability information on the periphery of the radio base stations or radio terminals. The radio base stations comprise radio environment information notification means for obtaining the environment information and capability information on the periphery and notifying the centralized control station. The centralized control station comprises simultaneous transmission control means for controlling allocation of channels and bandwidth as parameters for performing simultaneous transmission to a radio base station group selected as radio base stations that perform simultaneous transmission at the same frequency according to the environment information and capability information reported by the radio base stations.SELECTED DRAWING: Figure 1
