METHOD AND APPARATUS FOR TRANSMITTING/RECEIVING A REFERENCE SIGNAL IN A MOBILE COMMUNCATION SYSTEM USING A BEAM FORMING

摘要

The present invention relates to a method of a base station transmitting a reference signal in mobile communication system using beam forming. The method includes a step for determining beam forming information for transmitting a reference signal transmission beam determined differently in at least one of the transmission period and the beam width based on an area of reception regions where a plurality of transmission beams are received in a service region of the base station and a step for transmitting the reference signal transmission beam to corresponding reception regions according to the determined beam-forming information.
