摘要： Provided is a coordinated communication method in which a plurality of cells cooperate to perform multi-antenna transmission and reception in a cellular wireless communication system. A terminal wirelessly transmits channel state information (CSI) feedback to a serving cell and at least one coordinating cell. The serving cell and the coordinating cell perform multi-point coordinated communication using the CSI feedback. Even if the serving cell and the coordinating cell belong to different base stations, information exchange between the cells is minimized, so that a transmission delay and a traffic increment of a backhaul network can be prevented.

摘要： Disclosed is an encoding/decoding apparatus of a HARQ system using LDPC codes. A first LDPC code encoding apparatus encodes input information data and transmits the encoded data to the decoding apparatus. An interleaver interleaves the input information data. A second LDPC code encoder in parallel with the first LDPC code encoder performs LDPC code encoding on an output of the interleaver so as to transmit it to the decoding apparatus. The first LDPC code encoder transmits an output signal to the decoding apparatus at odd numbered retransmissions in response to a retransmission request from the decoding apparatus, and the second LDPC code encoder transmits an output signal to the decoding apparatus at even numbered retransmissions in response to the retransmission request from the decoding apparatus.
