Beam forming method and device for multiple terminal devices, base station and storage medium

The invention provides a beam forming method and device for multiple terminal devices, a base station and a storage medium, and relates to the technical field of communication, and the method comprises the steps: obtaining a transmitting signal and a receiving signal corresponding to the base station; determining a downlink channel capacity sum corresponding to at least two terminal devices communicating with the base station based on the transmitting signal corresponding to the base station; based on the received signal corresponding to the base station, determining the sum of uplink channel capacities corresponding to at least two terminal devices communicating with the base station; determining an average channel capacity corresponding to the at least two terminal devices based on the downlink channel capacity sum and the uplink channel capacity sum; and determining an optimal beamforming parameter by taking maximization of the average channel capacity as an optimization target.
