  • Method and device for allocating search space of control channel in subframe
    Patent number: 9681429
    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).
