Abstract: Embodiments of the present disclosure provide an antenna device and a base station comprising the same. The antenna device may comprise an antenna array with a radiation pattern including a main lobe and a back lobe; and a first reflector able to be configured to reflect a first part of energy of the back lobe to at least one direction different from a direction of the main lobe.

Abstract: Various embodiments of the present disclosure provide method and apparatus for aircraft traffic management. The method performed by an aircraft traffic management device comprises determining at least one cell shaping parameter based on cell information and a flight route of an aircraft. The method further comprises sending a request for creating at least one cell shaping beam for covering at least a part of the flight route of the aircraft to an operations support system, OSS, wherein the request includes the at least one cell shaping parameter.

Abstract: Embodiments of the present disclosure provide method and apparatus for positioning. The method may comprise receiving a first radio signal of a terminal device located in the area from a line of sight (LOS) path between the antenna array and the terminal device; receiving a second radio signal of the terminal device located in the area from at least one path reflected by the reflector; determining respective angles of arrival of the LOS path and the at least one path reflected by the reflector; and determining a location of the terminal device by using triangulation based on the respective angles of arrival.
