METHOD FOR REPORTING CHANNEL STATE INFORMATION, METHOD FOR SUPPORTING SAME, AND APPARATUS FOR SAID METHODS
First Claim
1. A method for receiving, by user equipment (UE), a channel state information (CSI)-reference signal (RS) in a wireless communication system, comprising:
- receiving CSI-RS resource configuration information o; and
receiving the CSI-RS based on the CSI-RS resource configuration information,wherein the CSI-RS resource configuration information includes information on a cell specific-RS (CRS) related to the CSI-RS, andthe UE assumes that an antenna port associated with the information on the CRS and an antenna port used to transmit the CSI-RS corresponding to the CSI-RS resource configuration information are quasi-co-located.

Abstract
According to one embodiment of the present invention, the method for receiving a channel state information (CSI)-reference signal (RS) from a wireless communication system by a user device comprises the steps of: receiving resource configuration information on the CSI-RS; and receiving the CSI-RS on the basis of the resource configuration information on the CIS-RS, wherein the resource configuration information on the CSI-RS includes information on a cell specific-RS (CRS) related to the CSI-RS, and the user device can assume that an antenna port related to information on the CRS and an antenna port used for transmitting CSI-RS corresponding to the resource configuration information on the CSI-RS are quasi co-located.
