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 is provided for receiving aperiodic channel state information (CSI). A base station (BS) transmits, to a user equipment (UE), an uplink downlink control information (DCI) format. The BS receives, from the UE, aperiodic CSI through a physical uplink shared channel (PUSCH) if the BS triggers an aperiodic CSI report using a CSI request field included in the uplink DCI format. The CSI request field is either a 1-bit field or a multi-bit field. When the UE is configured with only one cell, the 1-bit field is included in the uplink DCI. When the UE is configured with more than one channel state information-reference signal (CSI-RS), the multi-bit field is included in the uplink DCI.
