Claim Text:
1. A method for receiving control information by a user equipment (UE) in a wireless communication system, the method comprising: receiving, via higher layer signaling, an enhanced physical downlink control channel (EPDCCH) configuration; and performing blind decoding on a plurality of physical resource block (PRB) pairs corresponding to each of at least one EPDCCH PRB set based on the EPDCCH configuration, wherein in performing the blind decoding, demodulation for an EPDCCH is performed by using a EPDCCH demodulation reference signal (DMRS), wherein the EPDCCH configuration indicates an EPDCCH DMRS scrambling sequence parameter for the EPDCCH DMRS other than a scrambling identity for the EPDCCH DMRS, wherein a scrambling sequence for the EPDCCH DMRS is initialized based on an equation ‘(|n where ‘n wherein the scrambling identity (n wherein the scrambling identity n
