Abstract:
Disclosed is a method and apparatus for searching for a user equipment searching for a control channel in a multi-node system. The method comprises: searching inside an E-PDCCH region for a first piece of downlink control information (DCI), which is determined according to a transmission mode; and searching inside the E-PDCCH region for a second piece of DCI, regardless of the transmission mode, wherein the E-PDCCH region is a control channel region to which the DCI, which is decoded on the basis of a user equipment-specific reference signal (URS), is transmitted from a subframe comprising a plurality of orthogonal frequency division multiplexing (OFDM) symbols.
