Claim Text:
1. A method for decoding an enhanced physical downlink control channel (EPDCCH) by a user equipment (UE) in a wireless communication system, the method comprising: determining quasi co-location (QCL) regarding an antenna port for the EPDCCH; and decoding the EPDCCH based on the QCL regarding the antenna port for the EPDCCH, wherein, when a first assumption that an antenna port for a cell-specific reference signal (CRS), an antenna port for a UE-specific reference signal (RS) for a physical downlink shared channel (PDSCH), and an antenna port for a channel state information-RS (CSI-RS) are quasi co-located is applied, the EPDCCH is decoded on an assumption that the antenna port for the CRS and an antenna port for a demodulation RS (DMRS) for the EPDCCH are quasi co-located.
