Abstract:
The present invention relates to a wireless communication system, and more specifically, to a method and an apparatus for enhanced control channel-based operation. A method for a base station for transmitting a downlink control channel in a wireless communication system according to one embodiment of the present invention comprises the steps of: determining one antenna port to be used for the downlink control channel; mapping the downlink control channel to a resource element on the basis of a reference signal for the one antenna port; and transmitting the mapped downlink control channel to a terminal, wherein an index for the one antenna port can be determined on the basis of a control channel element (CCE) index of the downlink control channel derived from the terminal identifier.

Claim (Index 3):
A method of receiving an Enhanced Physical Downlink Control Channel, EPDCCH, by a user equipment (UE) in a wireless communication system, the method comprising:\n determining one antenna port used for the EPDCCH; and demodulating the EPDCCH based on a reference signal for the one antenna port, and wherein an index of the one antenna port is determined based on a value n\u2032 satisfying the following equation,\n n \u2032=(nECCE mod  d )+( X  mod min( L,d )), \n wherein, nECCE is a lowest ECCE index used for transmission of the EPDCCH; d is a number of ECCEs per resource block pair; X is an identifier of the UE; L is a number of ECCEs used for the EPDCCH; mod is modulo function; and min (L,d) is a minimum value of L and d.
