摘要

An apparatus and method for operating a base station and a mobile station in a communication system are provided. The operation of the base station includes persistently allocating resources to at least one mobile station and transmitting, in a current frame, a control information message including a change counter flag indicating whether persistent resource allocation information, transmitted in a previous frame, is changed. An operation of the mobile station includes receiving a control information message, including a change counter flag indicating whether persistent resource allocation information included in a control information message transmitted in a previous frame is changed, from a base station in a current frame and checking a value of the change counter flag.

1. A method for receiving a control information message by a mobile station in a communication system, the method comprising:
if normal reception of a first control information message in a previous frame is failed, transmitting, to a base station, a Negative Acknowledgement (NAK) message, stopping use of persistently allocated resources until a change counter flag, indicating whether persistent resource allocation information included in the first control information message is changed, is obtained, receiving, from the base station in a current frame, a second control information message including the change counter flag; checking a value of the change counter flag; and recognizing whether or not persistent resource allocation between the current frame and the previous frame is changed according to the checked value, wherein the first control information message and the second control information message are not stored by the mobile station.
