METHOD AND DEVICE FOR MONITORING DOWNLINK CHANNELS

摘要

Disclosed are a method and a device for monitoring a downlink control channel in a wireless communication system. The method for monitoring a downlink control channel in a wireless communication system may comprise the steps of: determining whether a common search space in a subframe exists in a physical downlink control channel (PDCCH) region or in an enhanced physical downlink control channel (ePDCCH) region; and, when the common search space exists in the ePDCCH region, monitoring, in the ePDCCH region, a downlink control channel for hybrid automatic repeat request (HARQ) acknowledgement (ACK) or non-acknowledgement (NACK) information.
