Title:
METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING REFERENCE SIGNAL IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/147475
Kind Code:
A1
Abstract:
The present invention relates to a wireless communication system and, more specifically, to a method and an apparatus for transmitting and receiving a reference signal (RS). The method for enabling user equipment (UE) of the wireless communication system to transmit an uplink signal according to one embodiment of the present invention comprises the steps of: receiving information on a plurality of parameter sets used for generating a sequence of RS; and generating and transmitting the sequence of the RS using one parameter set determined among the plurality of parameter sets. The parameters constituting the plurality of parameter sets can comprise the parameters commonly applied to the plurality of parameter sets and the parameters individually applied to the plurality of parameter sets.
