US 2015/0146644 A1 · METHOD AND DEVICE FOR RECEIVING DOWNLINK SIGNAL IN WIRELESS COMMUNICATION SYSTEM

Abstract

A method for a terminal for receiving a downlink signal according to an embodiment of the present invention comprises a step of receiving a channel state information-reference signal (CSI-RS) on the basis of CSI-RS configuration information elements containing quasi co-location cell-specific reference signal (QCL CRS), wherein the terminal receives the CSI-RS by means of a QCL assumption on the basis of the QCL CRS information, and if the information contained in the QCL CRS information and the information known to the terminal corresponding to the information contained in the QCL CRS are not in agreement, then the information known to the terminal is applied preferentially.

Dependent claims

A method for receiving a downlink signal by a user equipment (UE) in a wireless communication system, the method comprising:

receiving a channel state information-reference signal (CSI-RS) according to CSI-RS configuration information (CSI-RS-ConfigNZP information elements) including quasi co-location (QCL) cell-specific reference signal (CRS) information,
wherein the UE receives the CSI-RS using QCL assumption based on the QCL CRS information (qcl-CRS-Info), and
if information included in the QCL CRS information is not equal to information which corresponds to the information included in the QCL CRS information and is known to the UE, the information known to the UE is given priority and applied.

Dependencies are inferred from the claim text.
