    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. 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.

    摘要: An apparatus for reporting downlink channel quality in a high-speed packet communication system. A channel analyzer measures downlink channel quality from a received reference channel signal. A controller determines whether a current TTI (Transmission Time Interval) is a TTI corresponding to a multiple of a first TTI or a TTI corresponding to a multiple of a second TTI. If the current TTI is a TTI corresponding to a multiple of the first TTI, the controller determines CQ (Channel Quality) refreshment information for a downlink channel received from the Node B based on the measured downlink channel quality, and if the current TTI is a TTI corresponding to a multiple of the second TTI, the controller determines CQ refinement information for the downlink channel based on the measured downlink channel quality. A CQ information transmitter generates CQ refreshment information or CQ refinement information under the control of the controller, and transmits the generated CQ refreshment information or CQ refinement information over an uplink.

    摘要: A high-speed packet data communication system, wherein a channel condition determiner measures a signal-to-interference ratio (SIR) of a first uplink dedicated channel signal received from a UE, and calculates a difference between the measured SIR and a preset target SIR; a transmission power determiner compares the difference with preset thresholds, and determines an uplink power offset to be applied to a second uplink dedicated channel transmitting control information for packet data received at the UE according to a result of the comparison; and a transmitter transmits over a downlink the determined uplink power offset to the UE.
