Abstract
The present invention is related to a method and an apparatus for transmitting a reference signal in a wireless communication system. The present specification comprises transmitting at least one of the user equipment (UE)-specific value which is the parameter used for generating the UE-specific reference signal sequence to the UE, selecting one value out of at least one of the UE-specific value and cell-specific value, calculating an initialization value of pseudo-noise (PN) sequence based on the value selected, generating a first reference signal sequence using the initialization value of PN sequence, mapping the first reference signal sequence to a resource element, and transmitting a reference signal to the UE using the resource element to which the first reference signal sequence is mapped.
