The present invention relates to a method for transmitting an uplink reference signal in a multi-node system and a terminal using same. 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.

A method and an apparatus for transmitting a synchronization signal in a wireless communication system are provided. A base station transmits a primary synchronization signal (PSS) and a secondary synchronization signal (SSS) to a terminal through a macro node, and transmits a third synchronization signal (TSS) to the terminal through at least one radio remote head (RHH) having a cell identity (ID) that is identical to the macro node. The terminal performs synchronization based on at least one of the PSS, the SSS, and the TSS.

Provided are a method and an apparatus for reporting a channel quality indicator (CQI) in a multi-node system. A terminal measures the CQI on the basis of a final interference power in which interference from at least one node among a plurality of nodes, from which the terminal receives signals, is reduced, and reports the measured CQI to a base station. Improvement of system performance, such as a data rate increase can be expected.
