METHOD AND DEVICE FOR TRANSMITTING REFERENCE SIGNAL IN MULTI-ANTENNA SUPPORTING WIRELESS COMMUNICATION SYSTEM

摘要

The present invention relates to a method and a device for estimating a channel of a terminal in a wireless communication system that supports multiple antennas. Particularly, the method comprises the steps of receiving a channel state information-reference signal (CSI-RS) for a plurality of first domain antennas and a cell-specific reference signal (CRS) for a plurality of second domain antennas, and estimating the all of the channels on the basis of a first channel for the first domain antennas estimated from the CSI-RS and a second channel for the second domain antennas estimated from the CRS.

1. A method of estimating a channel by a user equipment in a wireless communication system supporting multiple antennas, the method comprising:
receiving a CSI-RS (channel state information-reference signal) for a plurality of first domain antennas and a CRS (cell-specific reference signal) for a plurality of second domain antennas; and estimating entire channels based on a first channel for the plurality of the first domain antennas estimated from the CSI-RS and a second channel for the plurality of the second domain antennas estimated from the CRS.
