Title:
METHOD FOR TRANSMITTING/RECEIVING REFERENCE SIGNAL IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/225935
Kind Code:
A1
Abstract:
The present invention relates to a method and a device for a terminal transmitting a reference signal in a wireless communication system. According to the present invention, a method and a device may be provided, the method comprising: receiving, from a base station, configuration information associated with a configuration of a first demodulation reference signal for demodulating uplink data; and on the basis of the configuration information, transmitting the first demodulation reference signal and the uplink data to the base station via at least one antenna port, wherein the first demodulation reference signal and the uplink data are transmitted in a subframe by means of frequency hopping, and the first demodulation reference signal is positioned on the same time axial symbol as that of at least one other demodulation reference signal transmitted on another antenna port.
