Abstract: Disclosed are a method and a device for allocating a search space of a control channel in a subframe. A method for monitoring downlink control information comprises the steps of: acquiring first control information on a first enhanced-physical downlink control channel (e-PDCCH) by monitoring a common search space in a first slot of a subframe; and acquiring second control information on a second e-PDCCH by monitoring a user equipment (UE)-specific search space in a second slot of the subframe. Thus, a terminal can obtain cell-specific information through an e-PDCCH even without a legacy physical downlink control channel (PDCCH).

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.
