APPARATUS AND METHOD FOR TRANSMITTING AND RECEIVING PACKET DATA CONTROL CHANNEL IN COMMUNICATION SYSTEM

摘要

PURPOSE: An apparatus and a method for transmitting and receiving a packet data control channel in a communication system are provided to support transmission of a packet data channel in a TDM(Time Division Multiplexing)/CDM(Code Division Multiplexing) format. CONSTITUTION: Feedback information on a forward channel environment is received from each terminal(401). It is determined which user data are to be transmitted by using information required for scheduling such as feedback information or a resource of a base station(402). It is judged whether only TDM is used or both TDM and CDM are used for a packet data channel(403). If only TDM is used, packet data control information of a corresponding user is transmitted through the first packet data control channel. the packet data control channel is allocated by users on the basis of a CQICH(Reverse Channel Quality Indicator Channel) indicating a forward channel environment of corresponding users(405).
