When reverse traffic is present, the apparatus and method can effectively demodulate and decode the reverse traffic. In a method for transmitting a reverse channel in the mobile communication system capable of discontinuously transmitting packet data, a transmission is performed by setting power of a Data Rate Indicator (DRI) channel to a predefined power when packet data is transmitted. When no packet data is transmitted, a transmission is performed by decreasing the power of the DRI channel.

摘要： An apparatus and method for receiving data in a mobile station for a mobile communication system using multi-user packet data are provided, in which a preamble power measurer measures preamble power of the multi-user packet data received from a base station and transmits the result value to a controller. The controller compares the measured power with a predetermined threshold, simultaneously decodes the multi-user packet data according to all transport formats if the measured power is lower than the threshold, and decodes the multi-user packet data according to a predetermined transport format if the measured power is higher than or equal to the threshold. A plurality of decoders decode the received multi-user packet data according to a control signal from the controller, wherein the number of the decoders depends upon the total number of transport formats for the multi-user packet data.
