METHOD FOR TRANSMITTING AN UPLINK REFERENCE SIGNAL IN A MULTI-NODE SYSTEM AND TERMINAL USING SAME

摘要

Provided are a method for transmitting an uplink reference signal in a multi-node system and a terminal using the method. The method comprises the steps of: receiving a synchronization signal from a node; receiving parameters for a virtual cell identifier (ID) from the node; generating an uplink demodulation reference signal (DM-RS) using the parameters for the virtual cell ID; and transmitting the generated uplink DM-RS to the node, wherein a physical cell ID is a cell ID obtained from the synchronization signal, and the parameters for the virtual cell ID are parameters used for generating the uplink DM-RS in the replacement of the physical cell ID.
