DEVICE AND METHOD FOR DETERMINING HIGH SPEED SHARED CONTROL CHANNEL IN A COMMUNICATION TERMINAL
First Claim
1. A method of detecting a high-speed shared control channel which transmits control information for demodulating a specific high-speed physical downlink shared channel in a communication terminal, the method comprising the steps of:
- recognizing decoding reliability for each high-speed shared control channel by decoding each of a plurality of high-speed shared control channels;
deciding a maximum and a minimum in the decoding reliability;
calculating a difference between the maximum and the minimum;
comparing the calculated difference with a preset critical value; and
detecting and processing a high-speed shared control channel corresponding to the maximum, when the difference exceeds the critical value.

Abstract
An apparatus and method for detecting high speed shared control channel of a communication terminal is provided, which recognizes decoding reliability for each of high-speed shared control channel by decoding each of a plurality of high-speed shared control channels; decides a maximum and a minimum in the decoding reliability, calculates a difference between the maximum and the minimum to compare the calculated difference with a preset critical value; and detects and processes a high-speed shared control channel corresponding to the maximum, when the difference exceeds the critical value. Accordingly, even though the wireless environment is inferior, the decoding reliability of an HS-SCCH can be more accurately decided in an HS-SCCH detection apparatus of the communications terminal and the detection performance of the HS-SCCH can be improved in a communication terminal.
