    Abstract: Provided are a method and an apparatus for measuring channel quality indicator in a wireless communication system. User equipment receives, from a base station, at least one of a cell-specific reference signal (CRS) which is cell-specifically transmitted and a channel state information reference signal (CSI RS). The user equipment also receives, from the base station, a demodulation reference signal (DMRS) which is user equipment-specifically transmitted in an enhanced physical downlink control channel (e-PDCCH) region constituted in a physical downlink shared channel (PDSCH) region. The terminal measures the CQI based on either at least one of the CRS and the CSI RS or the DMRS.

    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).
