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 of receiving a reference signal by a user equipment. A first channel state information-reference signal (CSI-RS) configuration related to a discovery of a transmission point is received. A second CSI-RS configuration related to a CSI measurement is received. A CSI-RS according to the first CSI-RS configuration or the second CSI-RS configuration is received. Feedback information is transmitted to a base station. If the CSI-RS has been received according to the first CSI-RS configuration, the feedback information includes information on a CSI-RS received strength. If the CSI-RS has been received according to the second CSI-RS configuration, the feedback information includes a result of the CSI measurement.

Abstract: Provided are a method and an apparatus for control channel decoding of a terminal in a multi-node system. The method sets a search space for searching a control channel and can perform the decoding by using different demodulation methods according to aggregation levels capable of constituting the control channel within the search space. In addition, the method determines the DCI format to be searched according to a transmission mode and can use different demodulation methods according to the determined DCI format. Furthermore, the method modulates DCI format to a first modulation degree when demodulating the DCI format, and can demodulate the DCI format to a second modulation degree when the DCI format is not detected.

Abstract: A method of transmitting control information includes dividing frequency bandwidth into ranges to which the same PMI (precoding matrix index) is applied, obtaining multiple antenna information by the range to which the same PMI is applied and transmitting the multiple antenna information. Since multiple antenna information is transmitted by the unit of a range to which the same PMI is applied, radio resources allocated for transmitting the multiple antenna information may be reduced, thereby enhancing data transmission efficiency.

Abstract translation: 发送控制信息的方法包括将频带宽度划分到应用了相同PMI（预编码矩阵索引）的范围内，通过应用相同PMI的范围获得多个天线信息并发送多个天线信息。 由于多个天线信息通过应用相同PMI的范围的单位发送，所以可以减少分配用于发送多个天线信息的无线电资源，从而提高数据传输效率。
