Abstract
A method for receiving a downlink signal by user equipment in a wireless communication system that supports coordinated multiple-point transmission and reception (CoMP) according to one embodiment of the present invention includes receiving information regarding two candidate demodulation reference signal (DMRS) groups for generating a sequence of downlink demodulation reference signals; and generating a sequence of downlink demodulation reference signals using one of at least two candidate DMRS configuration parameter sets. Each of at least two candidate DMRS configuration parameter sets includes a cell identifier and a scrambling identifier. The scrambling identifier included in one of at least two candidate DMRS configuration parameter sets may be determined whether the two cell identifiers included respectively in at least two candidate DMRS configuration parameter sets are the same or not.
