METHOD AND APPARATUS FOR TRANSMITTING REFERENCE SIGNAL

摘要

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.

1. A method for transmitting signals by a communication apparatus in a wireless communication system, the method comprising:
mapping, by the communication apparatus, a plurality of reference signals to one or more resource blocks; and transmitting, by the communication apparatus, the mapped plurality of reference signals on respective antenna ports of a first and second set of antenna ports, wherein each reference signal transmitted on the first set of antenna ports is code division multiplexed to a first group of resource elements in the one or more resource blocks by using a corresponding orthogonal sequence, wherein each reference signal transmitted on the second set of antenna ports is code division multiplexed to a second group of resource elements in the one or more resource blocks by using a corresponding orthogonal sequence, and wherein 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}.
