    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 and method for coding a semi-systematic block low density parity check (LDPC) code in which an information word is received and coded into a codeword including the information word, a first parity, a second parity, and a third parity, based on one of a first parity check matrix and a second parity check matrix, depending on a size to be applied when generating the information word into a semi-systematic block LDPC code. A part having a degree being at least equal to a predetermined degree is punctured from the information word, generating the semi-systematic block LDPC code. The semi-systematic block LDPC code includes the information word, the part of which was punctured, the first parity, the second parity, and the third parity.
