Abstract

This specification relates to a method for selecting a node in a serving cell in a distributed multi-node system, the method being characterized by comprising the steps of: receiving a channel state information reference signal of each node in the serving cell from a base station; measuring a signal intensity or interference level about the respective nodes through the received channel state information reference signal; and determining at least one valid node from among the respective nodes based on the measured result, wherein the signal intensity or the interference level is expressed in any 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).
