Abstract:
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.
