Abstract

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. 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.

Description

[0001] This application claims the priority of the application titled "Apparatus and Method of Coding and Decoding CQI Information in Communication System Using High Speed ​​Downlink Packet Access (Apparatus and Method of Coding and Decoding CQI Information in Communication System Using High Speed ​​Downlink Packet Access)", which Filed to the Korean Industrial Property Office on March 26, 2002, assigned serial number No. 2002-16561, the contents of which are incorporated herein by reference. technical field [0002] The invention relates to a device and method for encoding and decoding CQI (Channel Quality Indicator) information in a communication system using HSDPA (High Speed ​​Downlink Packet Access, high-speed downlink packet access), in particular to a The following device and method for encoding and decoding CQI information, the device and method can insert a pilot signal into a HS-PDSCH (High Speed-Physical Downlink Shared CHannel, high-speed physical downlink shared ch...
