Abstract
In a mobile communication system including a base station provided with a plurality of antenna ports, and user equipment that executes radio communication with the base station, the base station transmits a beam stream including a first beam for transmitting data to the user equipment, and one or more second beams for transmitting a precoded reference signal in a direction toward a vicinity of the first beam; and upon receiving the beam stream, the user equipment selects, from the first beam and the second beam, and transmits, to the base station, one or more suitable beam indexes.
