METHOD AND APPARATUS FOR REPORMING BUFFER STATUS REPORTING BY USING PROJECTED BUFFER STATUS IN A MOBILE TELECOMMUNICATION SYSTEM

摘要

A method and apparatus for reporting a Buffer Status (BS) using Node B-estimated BS information in a mobile communication system are provided. A Node B-estimated BS and an actual BS of a User Equipment (UE) are monitored. A value of the Node B-estimated BS is compared with a first threshold value. If the Node B-estimated BS value is less than the first threshold, a determination is made as to whether the value of the actual BS is more than a second threshold. If the actual BS value is more than the second threshold, a Buffer Status Report (BSR) indicative of the actual BS is transmitted to a Node B.
