Abstract

The present invention relates to a wireless communication system, and more specifically disclosed are a method and an apparatus for transmitting or receiving a downlink signal by considering an antenna port relationship. A method for user equipment decoding an enhanced physical downlink control channel (EPDCCH) in the wireless communication system, according to one embodiment of the present invention comprises the steps of: determining from a downlink subframe a reference element (RE) on which the EPDCCH is mapped; and decoding the EPDCCH based on the RE on which the EPDCCH is mapped. At least one EPDCCH physical resource block (PRB) set for monitoring the EPDCCH can be established for the user equipment, wherein a parameter set for each of the at least one EPDCCH PRB set is indicated by an upper layer and the RE on which the EPDCCH is mapped can be determined based on the parameter set indicated by the upper layer.
