BEAM SELECTING METHOD, BASE STATION, AND USER EQUIPMENT |
| 摘要 |
A beam selection method in a mobile communication system including a base station with multiple antennas and user equipment conducting radio communication with the base station includes the steps of, at the base station, detecting a direction in which the user equipment is located, transmitting precoded reference signals toward the detected direction by spatial multiplexing using same frequency and time resources, and determining a beam for the user equipment based upon feedback information from the user equipment. |
