摘要： A scheme of error decoupling for carrier aggregation techniques to support a communication system is provided. The communication system operates with up to 2 codewords for up to 5 carriers, each codeword of each carrier having one acknowledgement/negative acknowledgement (ACK/NACK) or discontinuous transmission (DTX) to enable Hybrid Automatic Repeat reQuest (HARQ) to operate in each carrier. The scheme involves the steps of: performing separation of bits related to ACK, NACK, DTX for each carrier using up to 2 codewords; determining a maximum number of bits related to ACK, NACK, DTX when decoupling is not performed after a maximum number of carriers are used; and grouping the carriers such that separation between ACK, NACK, DTX of each carrier is optimized as long as the maximum number of bits is not exceeded.

摘要： The present invention relates to a wireless communication system, and more particularly, to a method and device for transmitting/receiving a signal by using a codebook. According to an embodiment of the present invention, the method for a transmitter supporting Nt antennas to attain the technical objects thereof and transmit a signal to a receive includes selecting the precoding matrix indicated by the combination of a first precoding matrix indicator (PMI) and a second PMI, precoding the signal by using the selected precoding matrix, and transmitting the precoded signal through the Nt antennas. Here, the first PMI may indicate one matrix group among N matrix groups (N≧1) including matrices representing channel directions related to the Nt antennas. Additionally, the precoding matrix may be selected by multiplying the one matrix group indicated by the first PMI by the matrix indicated by the second PMI.

摘要： The present invention relates to a method for enabling a terminal to report channel state information in a wireless communication system for supporting coordinated multi point (CoMP) transmission. Specifically, the method for enabling the terminal to report the channel state information in the wireless communication system for supporting CoMP transmission includes the steps of: receiving a reference signal from a serving cell and one or more cooperated cells; forming the channel state information for the CoMP transmission on the basis of the reference signal; and reporting the channel state information through a physical uplink shared channel to the serving cell, wherein the channel state information includes channel quality indicator (CQI) information and precoding matrix index (PMI) information, and the CQI information includes a wideband CQI and a CQI for each selected sub-band of the CoMP transmission.
