Abstract
The present description relates to a method for receiving a reference signal (RS) in a distributed multi-node system, comprising: a step of receiving, from a base station, channel state information reference signal (CSI-RS) configuration information which indicates the configuration of the channel state information reference signal the power of which is nonzero; and a step of receiving a channel state information reference signal for at least one node in a cell on the basis of the channel state information reference signal configuration information, wherein said channel state information reference signal with non-zero power has at least one configuration, and is received via at least one subframe.
