Apparatus and method of determining uplink priority in wireless mobile communication system

摘要

Provided is a wireless mobile communication system in which a mobile station reports a headroom value indicating the magnitude of currently used transmission power and additionally usable transmission power. An uplink scheduling method of a Base Transceiver Station (BTS) includes normalizing the headroom value according to a pre-set reference transmission format; determining a mean data rate of the mobile station; and determining a priority of the mobile station considering the normalized headroom value and the mean data rate.
