METHOD FOR IMPROVING CELL PERFORMANCE USING THE FEEDBACK OF PRECODER RECOMMENDATION INFORMATION IN MULTI-CELL WIRELESS NETWORK

摘要

PURPOSE: A cell performance improvement method is provided to minimize overhead using feedback of pre-coder recommendation information in a wireless network. CONSTITUTION: A base station transmits data to a service target terminal according to an initial beam pattern by cooperating between cells(40). The base station receives pre-coder recommendation information from other terminal. The base station changes the service target terminal and the initial beam pattern based on the pre-coder recommendation information by selecting a beam pattern change through a cooperation between the cells(42).
