APPARATUS AND METHOD FOR CODING AND DECODING OF CQI INFORMATION IN COMMUNICATION SYSTEM USING HIGH SPEED DOWNLINK PACKET ACCESS SCHEME

摘要

A method for transmitting pilot bits instead of partial bits of CQI (Channel Quality Indicator) information indicating channel quality of an HS-PDSCH (High Speed-Physical Downlink Shared CHannel) in a CDMA (Code Division Multiple Access) communication system such that a Node B can control power of a high-speed uplink control channel. The system transmits high-speed packet data from the Node-B to UE (User Equipment) through the HS-PDSCH, and the UE is located in a handover area between the Node-B and another Node-B adjacent thereto. In the method, the CQI information is received and code symbols of given bits are generated. Predetermined bits are then removed from given bits of the code symbols. The removed bits are then replaced with high-speed pilot bits for power control.
