PROCESSING PACKET DATA IN MOBILE COMMUNICATION SYSTEM

摘要

A packet data processing device for a mobile communication system. A base station includes a channel status information receiver for receiving channel status information for a forward channel from a mobile station; a supplemental channel transmission controller for determining a bit rate of the mobile station according to the channel status information, a supplemental channel transmitter for transmitting data to the mobile station at the bit rate determined by the supplemental channel transmission controller; and a rate indicator transmitter for generating a rate indicator having information about the determined bit rate and transmitting the generated rate indicator to the mobile station. The mobile station includes a channel status measurer for detecting power of a signal received over a pilot channel to measure channel status; a channel status information transmitter for generating channel status information according to the measured channel status and transmitting the channel status information to a base station; and a supplemental channel receiver for detecting a bit rate of data transmitted at a variable rate from the base station and receiving data at the detected bit rate.
