Title:
METHOD FOR TRANSMITTING/RECEIVING REFERENCE SIGNAL IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/031854
Kind Code:
A1
Abstract:
The present invention relates to a method and a device for transmitting/receiving a reference signal by means of a terminal in a wireless communication system. According to the present invention, a method and a device may be provided whereby a terminal receives control information from a base station, and receives a reference signal on the basis of the control information. The reference signal is transmitted on a specific antenna port and is positioned in the same symbol, on a time axis, and in the same subcarrier, on a frequency axis, as a different reference signal transmitted on at least one other antenna port. The specific antenna port and the at least one other antenna port are multiplexed by a code division multiplexing (CDM) method by having an orthogonal cover code (OCC) applied thereto, and the subcarrier has applied thereto, according to an index of the subcarrier, the OCC or a value derived as a result of the shifting of the OCC.
