Method and Apparatus for Selecting a Node in a Distributed Multi-Node System

A terminal for selecting nodes in a serving cell in a distributed multi-node system (DMNS), the terminal comprising:

• a radio frequency (RF) unit for transmitting a radio signal to and receiving a radio signal from an outside;
• and
• a controller connected to the RF unit,
• wherein the controller controls the RF unit to receive STI-RSs for the nodes in the serving cell from a BS, measures signal intensities or interference levels for the nodes through the received CSI-RSs, and performs control so that at least one valid node is determined among the nodes, and
• wherein the signal intensities or the interference levels are expressed as one of channel state information reference signal received power (CSI-RSRP), channel state information reference signal received quality (CSI-RSRQ), and channel state information reference signal's signal intensity (CSI-RSSI).

A method of selecting nodes in a serving cell in a distributed multi-node system (DMNS), the method comprising:

• transmitting CSI-RSs for nodes in the serving cell to terminal;
• receiving measurement results of signal intensities or interference levels for the nodes from the terminal;
• and
• determining at least one valid node among the nodes based on the received measurement results.
