Abstract: A method is provided for receiving a downlink control channel in a wireless communication system. A user equipment performs a blind decoding in a first search space on the cell to find a first Physical Downlink Control Channel (PDCCH). The user equipment receives a Radio Resource Control (RRC) message including information on a second search space for monitoring a second PDCCH and identity information, and performs a blind decoding in the second search space on the cell to find the second PDCCH. The first PDCCH is demodulated based on a physical cell identity of the cell, and the second PDCCH is demodulated based on the identity information instead of the physical cell identity.

Abstract: A method is presented for receiving aperiodic channel state information (CSI). A base station (BS) transmits a CSI request field which is set to trigger a CSI report to a user equipment (UE). The BS 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. 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.

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).
