Wireless communication system
First Claim
1. A wireless communication system in which a central base station and a plurality of remote base stations are connected by a communication medium such as a fiber-optic cable, and the remote base station performs wireless communication with a plurality of mobile stations;
- the remote base station comprising a direction-variable antenna of which directivity varies with an electric signal supplied to a plurality of antenna elements; and
the central base station holding area information of a beam pattern of the remote base station serving each mobile station and combination information of beam patterns causing interference among the remote base stations, referencing the combination information in accordance with allocation priority information of the mobile station, and performing packet scheduling of the mobile station so that interference of radio waves sent from the remote base stations to the mobile stations can be suppressed.

Abstract
A wireless communication which suppresses radio interference between wireless base stations and improves the channel efficiency is implemented. In the wireless communication system including a central base station, a plurality of remote base stations having a direction-variable antenna, and a plurality of mobile stations to communicate with the remote base stations, the central base station performs centralized management of radio-wave beam patterns to be sent to the plurality of mobile stations which will communicate with remote base stations and performs packet scheduling of the mobile stations in such a manner that radio waves sent from the remote base stations will not cause strong interference at the mobile stations.
