Abstract

Disclosed is a method for reporting channel state information between a mobile station and a base station to the base station by the mobile station in a mobile communication system. The method includes the steps of mapping the channel state information to a value stored in a channel state information table. The mapping is determined by a range of traffic-to-pilot ratio (TPR) values. The TPR values are determined according to an encoder packet site packet data rate relation. The mapping is then transmitted to the base station.
