Embodiments of this application provide a data sending method, an apparatus, a device, and a readable storage medium. A server determines a first transmission point from a coordinated set, and determines a first downlink sending weight of the first transmission point. Then, the server determines a second downlink sending weight of a second transmission point based on the first downlink sending weight, and sends the second downlink sending weight to the second transmission point. When sending a data stream to an electronic device, the second transmission point determines a downlink sending weight corresponding to the data stream from a matrix, weights the data stream, and sends the weighted data stream to the electronic device.
