METHOD FOR ESTIMATING CHANNEL STATE IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR

摘要

The present invention relates to a wireless communication system. More specifically, the present invention relates to a method for reporting a channel state by a terminal to a serving base station in a wireless communication system, wherein extra channel state information is reported to enable the serving base station to estimate the channel state more accurately. When the base station estimates the channel state with the terminal, the channel state information received from the terminal, the extra channel state information, and traffic information of neighboring base stations are collectively considered to estimate the channel state with the terminal, thereby enabling estimation of the channel state with improved reliability and accuracy.

主权项

1. A method of reporting a channel state, which is reported by a user equipment to a serving eNode B in a wireless communication system, comprising the steps of:
calculating a first channel state information based on a first interference strength corresponding to an interference strength from a first eNode B group; and calculating a second channel state information based on an identification information of an eNode B belonging to a second eNode B group, wherein the second channel state information is used for correcting the first channel state information and wherein the serving eNode B estimates the channel state based on the corrected first channel state information.
