Title:
METHOD AND DEVICE FOR EFFICIENTLY TRANSMITTING PRECODED REFERENCE SIGNAL IN RADIO COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2010/137925
Kind Code:
A3
Abstract:
The present invention relates to a radio communication system, and more particularly, a method and a device for efficiently transmitting precoded reference signals. The method for transmitting reference signals in multiple antenna transmission, according to one embodiment of the present invention, comprises the steps of: determining a precoding vector for each of M layers (M≥3; M is a natural number); precoding a reference signal for each of the M layers in accordance with said precoding vector; multiplexing the precoded reference signals for N layers (N
