Beam forming method, network equipment and terminal equipment

The invention provides a beam forming method, network equipment and terminal equipment, and the method comprises the steps that the network equipment obtains the arrival angle variable quantity of an uplink signal from the terminal equipment in a current period relative to a previous period, the angle-of-arrival variable quantity is related to Doppler frequency shift of the terminal equipment relative to the network equipment; and the network equipment performs beam forming on a downlink signal according to the angle of arrival variable quantity. The beam forming method has the advantages of being low in implementation difficulty, high in applicability and the like, and can meet the use requirements of an NTN communication system with a civil aircraft as an air-based platform.
