DEVICE AND METHOD FOR TRANSMITTING REFERENCE SIGNAL IN MULTI-ANTENNA SYSTEM

摘要

The present invention relates to a device and a method for transmitting a reference signal in a multi-antenna system. The present specification discloses a method for receiving a reference signal, the method comprising the steps of: receiving, from a base station, first channel state information (CSI) reference signal (CSI-RS) configuration information including individual parameters necessary when a terminal receives a first CSI-RS from a horizontally adjacent horizontal representative antenna among the all of the transmission antennas of the base station and second CSI-RS configuration information including individual parameters necessary when the terminal receives a second CSI-RS from a vertically adjacent vertical representative antenna; and receiving the respective first and second CSI-RSs from the base station on the basis of the first CSI-RS configuration information and the second CSI-RS configuration information.

1. A method of receiving a reference signal (RS) by user equipment (UE) in a multiple antenna system, the method comprising:
receiving, from a base station, first channel state information reference signal (CSI-RS) configuration information including an individual parameter used for the UE to receive a first CSI-RS from an adjacent horizontal representative antenna and second CSI-RS configuration information including an individual parameter used for the UE to receive a second CSI-RS from an adjacent vertical representative antenna among entire transmission antennas of the base station; and receiving the first CSI-RS and the second CSI-RS based on the first and second CSI-RS configuration information, respectively.
