Method and System for Reporting Channel State Information Based on Channel Quality in Portable Internet System

摘要

The present invention is a method and system for reporting channel state information based on the channel quality in the mobile Internet system relates to a ; The present invention, a subscriber station in a portable Internet system. (SS: Subscriber Station) of the channel to the base station based on the quality (BS: Base Station) with a method for reporting channel state information , (a) the channel quality threshold value (CQT: Channel Quality Threshold) by the subscriber station from the base station transmitting the CQI (Channel Quality Information) channel assignment message containing the information; (B) comparing the channel quality value of the transmitted and the channel quality threshold value, the subscriber station included in the CQI channel assignment message; And (c) if the comparison results, the channel quality value of the step (b) is greater than the channel quality threshold, the channel state information of the subscriber station from the subscriber station using the CQI channel allocated to the subscriber station In a portable Internet system that is characterized in comprising the steps of: receiving a subscriber station based on the channel quality to a method and system for reporting channel state information to the base station. ; According to the invention, the base station from a collision between the adjacent cells by limiting the user of the imprudent use of the CQI channel to limit the use of the CQI channel to the subscriber station by the channel quality threshold by including the channel quality threshold value on the CQI channel assignment message transmitted by the subscriber station there is a decreasing effect.
