METHOD FOR RECEIVING CONTROL INFORMATION ON EPDCCH
First Claim
1. A method of receiving control information comprising:
- receiving information on a change in a pattern of a demodulation reference signal (DMRS);
identifying a time at which mapping between an enhanced control channel element (ECCE) and an enhanced resource element group (EREG) for an enhanced physical downlink control channel (EPDCCH) is changed according to the change in the pattern of the DMRS; and
receiving control information through the EPDCCH by applying the changed mapping at the identified time.

Abstract
In one embodiment of the present specification, provided is a method for receiving control information on an enhanced physical downlink control channel (EPDCCH). The method for receiving control information may comprise the steps of: receiving information associated with a pattern change of a demodulation reference signal (DMRS); identifying a time of changing mapping between an enhanced resource element group (EREG) and an enhanced control channel element (ECCE) for an EPDCCH, according to the pattern change of the DMRS; and receiving control information on the EPDCCH by applying the change of the mapping at the identified time.

9. A terminal for receiving control information comprising:
-
a radio frequency (RF) unit to receive information on a change in a pattern of a demodulation reference signal (DMRS); and a processor to identify a time at which mapping between an enhanced control channel element (ECCE) and an enhanced resource element group (EREG) for an enhanced physical downlink control channel (EPDCCH) is changed according to the change in the pattern of the DMRS, wherein the processor controls the RF unit to receive control information through the EPDCCH by applying the changed mapping at the identified time. - View Dependent Claims (10, 11, 12, 13, 14, 15)
