Method and apparatus for performing channel measurement in a distributed multi-node system

摘要

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.

1. A method for receiving a reference signal (RS) in a distributed multi-node system, the method comprising:
receiving channel state information reference signal (CSI-RS) configuration information from a base station, wherein the CSI-RS configuration information indicates a non-zero power configuration of a CSI-RS; and receiving a non-zero power CSI-RS on at least one node in a cell based on the CSI-RS configuration information, wherein the non-zero power CSI-RS has multiple configurations and is received within a single subframe, wherein, if the non-zero power CSI-RS is received through at least two subframes, the non-zero power CSI-RS is received at a predetermined frame offset interval or at an integer-multiple duty cycle interval based on the received single subframe.
