Title:
WIRELESS COMMUNICATION SYSTEM AND METHOD OF CONTROLLING WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/122974
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a wireless communication system and a method of controlling the wireless communication system for recovering a wireless link early when disruption or quality degradation of wireless communication between a base station and a wireless communication terminal occurs. In a wireless communication system according to the present invention, a base station having detected disruption or quality degradation of wireless communication transmits a wireless link recovery request to each of base stations written in an antenna setting order list, with antenna setting information for recovery of the same wireless link included in each of the transmitted wireless link recovery requests, and a transmitting/receiving unit 10 of the base station having transmitted the wireless link recovery request and each of the base stations having received the wireless link recovery request transmits a training signal for wireless link recovery on the basis of the antenna setting order list and time-of-day information at a time when the training signal for wireless link recovery is not transmitted at the same frequency simultaneously from a plurality of base stations.
