Method and wireless device for monitoring control channel

摘要

Provided are a method and a wireless device for monitoring a control channel in a wireless communication system. The wireless device monitors a first downlink control channel in a common search space of a subframe, and monitors a second downlink control channel in a user equipment-specific search space of the subframe. The first downlink control channel is modulated by a cell-specific reference signal, and the second downlink control channel is modulated by a reference signal that is specific to the wireless device.

主权项

1. A method of monitoring a control channel in a wireless communication system, the method comprising:
receiving, by a wireless device, from a base station, a radio resource control (RRC) signal, the RRC signal including first information on at least one subframe on which at least one enhanced physical downlink control channel (EPDCCH) is monitored and second information on a user equipment (UE)-specific search space; monitoring, by a wireless device, a physical downlink control channel (PDCCH) in a common search space of a subframe; and monitoring, by the wireless device, the EPDCCH in the UE-specific search space on the subframe indicated by the first information, wherein the EPDCCH is demodulated by a demodulation reference signal (DMRS).
