Title:
WIRELESS COMMUNICATION SYSTEM, BASE STATION, AND WIRELESS TERMINAL
Document Type and Number:
WIPO Patent Application WO/2013/111455
Kind Code:
A1
Abstract:
Provided is a system which is designed to share the same frequency band among base stations to improve frequency usage efficiency, with which deterioration in receiving quality from inter-base station interference and resulting deterioration in throughput from difficulty in MIMO transmission is avoided. Scheduling is carried out such that different streams are used with base stations which are experiencing interference. When transmitting to a terminal, by issuing a notification of a wireless resource allocation to the terminal together with Pilot information of a base station which is an interfering station, an interference signal from the interfering station is split in the terminal.
