Abstract: A method for efficiently transmitting and receiving downlink control information is disclosed. The method includes, at a base station, receiving feedback information including a precoding matrix index (PMI) from a user equipment (UE) and transmitting precoding information having a predetermined bit number according to the number of antenna ports and a transmission mode of the base station. The precoding information of a predetermined transmission mode in the precoding information includes confirmation information indicating that the base station uses a PMI which is recently received from the UE.

Abstract: The present invention relates to a method and device for decoding a channel in a wireless communication system. User equipment receives, from a base station, a candidate group of antenna ports including a plurality of antenna ports, and receives a reference signal from the base station onto enhanced physical downlink control channel (e-PDCCH) ports that correspond to all or some of the plurality of antennas in the candidate group of antenna ports. The user equipment blind-decodes the e-PDCCH configured in a physical downlink shared channel (PDSCH), on the basis of the received reference signal.

Abstract: A method performed by a base station (BS) is provided for receiving aperiodic channel state information (CSI). The BS transmits a CSI request field which is set to trigger a CSI report to a user equipment (UE), and receives CSI through a physical uplink shared channel (PUSCH) from the UE. The CSI request field has a value among a plurality of candidate values and the plurality of candidate values comprises a first value which triggers an aperiodic CSI report for a first set of reference signals and a second value which triggers an aperiodic CSI report for a second set of reference signals. The first set and the second set of reference signals are configured by a higher layer signal.

CPC classification number: H04L1/08
Abstract: A method of transmitting data in a wireless communication system is provided. The method includes generating duplicate data by using repetition coding, the duplicate data being the same as original data, shifting the phase of the duplicate data, and transmitting the original data and the phase-shifted duplicate data. The duplicate data is mapped to a modulation symbol having a different size or phase as that of the original data, thus to reduce the PAPR unlike the general repetition coding.

Abstract: A method for correcting errors in a multiple antenna system based on a plurality of sub-carriers and a transmitting/receiving apparatus supporting the same are disclosed. The method includes determining a phase shift based precoding matrix phase shifted at a predetermined phase angle, initially transmitting each sub-carrier symbol to a receiver in a packet unit by using the phase shift based precoding matrix, reconstructing the phase shift based precoding matrix to reduce a spatial multiplexing rate if a negative reception acknowledgement (NACK) is received from the receiver, and retransmitting the initially transmitted sub-carrier symbol by using the reconstructed phase shift based precoding matrix or by changing the phase shift based precoding matrix using offset information fed back from the receiver or random offset information.
