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.

Claim (Index 6):
The method of  claim 5 , wherein blind decoding is performed to determine whether or not a demodulation reference signal is transmitted through the allocated antenna port and one or more different antenna ports,\n wherein an antenna port on which the blind decoding is performed by the UE is determined based on a Table 2 described in the following according to an antenna port allocated to the UE, and TABLE 2 Antenna ports on which blind decoding is Allocated antenna port performed #7 #8, #8\u2032, #11, #13 #8 #7, #11, #13 #11 #7, #8, #13 #13 #7, #8, #11 wherein an antenna port #8\u2032 of the Table 2 indicates an antenna port where a Walsh sequence [e f g h] corresponding to an antenna port #8 is mapped to repeat an order of [e f g h] pattern and [h g f e] pattern to transmit a modulation reference signal.
