Claim Text:
1. A method for monitoring a control channel in a wireless communication system, the method comprising: receiving, by a user equipment (UE), information about a cell identifier identifying a serving cell on which a physical downlink control channel (PDCCH) for the UE is to be monitored; receiving, by the UE, information about a cell-radio network temporary identifier (C-RNTI) identifying the UE by the serving cell; monitoring, by the UE, the PDCCH in a UE-specific search space of a subframe based on a starting point of the UE-specific search space, the starting point of the UE-specific search space being determined based on at least one of the C-RNTI and the cell identifier; and receiving, by the UE, the PDCCH having a Cyclic Redundancy Check (CRC) destined to the UE that is masked with the C-RNTI but not the cell identifier, wherein the PDCCH is received by determining the starting point of the UE-specific search space based on the C-RNTI if monitoring a common search space which is monitored by all UEs is switched on, and the PDCCH is received by determining the starting point of the UE-specific search space based on both the cell identifier and the C-RNTI if monitoring the common search space is switched off.
