Abstract
Provided are a method and device for downlink control channel allocation in a wireless communication system. A base station allocates e-PDCCH (enhanced physical downlink control channel) to one slot in a subframe, and transmits a DMRS (demodulation reference signal) after allocating the DMRS to one of the slots for the e-PDCCH.
Claims15
A method for allocating, by a base station, a downlink control channel in a wireless communication system, the method comprising:
- allocating an enhanced physical downlink control channel (e-PDCCH) to one slot in a subframe;
- and
- allocating a demodulation reference signal (DMRS) for the e-PDCCH to the one slot and transmitting the allocated DMRS.
A method for allocating, by a base station, an antenna port in a wireless communication system, the method comprising:
- allocating an enhanced physical downlink control channel (e-PDCCH) to a data region in a resource block (RB);
- allocating at least one antenna port for transmission of the e-PDCCH;
- and
- transmitting the allocated e-PDCCH to the UE through one antenna port from the at least one antenna port.
A method for receiving, by a user equipment (UE), a downlink control channel in a wireless communication system, the method comprising:
- allocating an enhanced physical downlink control channel (e-PDCCH) to a data region in a resource block (RB);
- and
- receiving the e-PDCCH and a demodulation reference signal (DMRS) through an antenna port allocated by a base station.
