Method and apparatus for transmitting reference signal
First Claim
1. A method of mapping signals in a wireless communication system, the method comprising:
- mapping first reference signals for each antenna port of a first set of antenna ports to a first group of resource elements in one or more resource blocks; and
mapping second reference signals for each antenna port of a second set of antenna ports to a second group of resource elements in the one or more resource blocks,wherein orthogonal sequences are multiplied with the first reference signals or the second reference signals, andwherein the first set of antenna ports comprises antenna ports {N, N+1, N+4, N+6} and the second set of antenna ports comprises antenna ports {N+2, N+3, N+5, N+7}.

Abstract
The present invention relates to a wireless communication system, and more specifically, to a method and an apparatus for transmitting an RS (Reference Signal) from a transmission end. The present invention relates to an RS transmission method and an apparatus therefore, comprising the steps of: confirming RS resources which are defined according to each layer; and transmitting the precoded RS for the layers to a receiving end through a multiple antenna, wherein the RS resource includes a 1st index for indicating an RS resource pattern group in which the precoded RS is mapped within a resource block and a 2nd index for indicating a code resource for multiplexing the precoded RSs within the RS resource pattern group.
