摘要:
Embodiments of the disclosure provide methods and apparatuses for three-dimensional beamforming. The method may comprise: mapping vertical virtual antenna ports to physical antenna ports based on vertical reference signals to obtain mapped vertical reference signals; transmitting the mapped vertical reference signals to a user equipment; receiving a tilting indicator from the user equipment, wherein the tilting indicator is obtained based on the mapped vertical reference signals at the user equipment; determining a tilting vector based on the received tilting indicator, wherein the tilting vector indicates adjustment for traffic data in antenna vertical tilting; and adjusting traffic data with the tilting vector.
