Abstract: Disclosed is a method by which a terminal reports channel quality information (CQI) to a base station in a multi-antenna-based wireless communication system. Particularly, the method comprises the steps of: receiving, through an upper layer, the reference signal configuration defined by P number of antenna ports; receiving, through M number of antenna ports, reference signals from the base station; grouping the P number of antenna ports into antenna port groups formed of the M number of antenna ports; calculating CQIs by using the reference signal corresponding to each of the antenna port groups on the basis of the assumption that predefined precoders are applied to the reference signals; and reporting, to the base station, N number of CQIs among the calculated CQIs.

Abstract: The present invention relates to a wireless communication system, and specifically provides a method for transmitting and receiving a demodulation reference signal (DMRS), and an apparatus using the same. More specifically, the present invention provides a method for transmitting and receiving a DMRS and an apparatus using the same, wherein a base station allocates a Walsh sequence for each antenna port to the DMRS for each antenna port using a method that is different from conventional methods, and thereby increases the number of user equipment that are MU-MIMO paired compared to the past, and can satisfy orthogonality between four DMRS sequences in both time and frequency domains so that user equipment receiving the DMRS can efficiently estimate a channel.
