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 3):
The method of  claim 1 , wherein an each element value of the Walsh sequence Wp=[a b c d] is determined based on a Table 1 described in the following: TABLE 1 Antenna port p [a b c d] #7 [+1 +1 +1 +1] #8 [+1 \u22121 +1 \u22121] #11 [+1 +1 \u22121 \u22121] #13 [+1 \u22121 \u22121 +1]
