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.
