Abstract:
1. A method for reporting downlink channel quality in a high-speed packet data communication system, comprising the steps of: measuring downlink channel quality from a reference channel signal received from a Node B; after measuring the downlink channel quality, determining whether a current TTI (Transmission Time Interval) is a TTI corresponding to a multiple of a first transmission period or a TTI corresponding to a multiple of a second transmission period; if the current TTI is a TTI corresponding to a multiple of the first transmission period, determining CQ (Channel Quality) refreshment information for a downlink channel received from the Node B based on the measured downlink channel quality, and transmitting the determined CQ refreshment information to the Node B; and if the current TTI is a TTI corresponding to a multiple of the second transmission period, determining CQ refinement information for the downlink channel based on the measured downlink channel quality, and transmitting the determined CQ refinement information to the Node B.
