APPARATUS AND METHOD FOR RECEVING CONTROL MESSAGE OF PDCCH IN A MOBILE COMMUNICATION SYSTEM SUPPORTING PACKET DATA SERVICE

摘要

This invention relates to an apparatus and method for improving the success rate of transmission of data in a mobile communication system. and, in particular, in a mobile communication system for transmitting packet data to a device and method to improve the receiving efficiency of the packet data control information. ; apparatus according to the first embodiment of the present invention, packet data and the transmission, the packet data transmission with a mobile packet data control channel for transmitting control information related to the communication system, a packet data control channel receiver, receives the signal of the signal and the packet data control channel of the reverse packet data channel spread and output separately to each signal, the receiver outputs the received signal to estimate the noise, the noise estimation value and the packet data control channel of the received signal samples to the reception of a packet data control channel information from the receiver and a signal level detector for detecting and outputting a validation signal, the signal received from the level detector when the validity signal is valid characterized in that it comprises a packet data control channel decoder for decoding an output signal of the packet data control channel.
