    摘要： This application relates to the communications field and provides a method and an apparatus for determining a scheduling user, and a system. The method for determining a scheduling user is applied to a first base station, and the first base station manages a first cell. The method includes: determining a first pre-scheduling user at a second moment from a user in the first cell at a first moment; determining a first transmit weight of the first cell at the second moment; receiving a second transmit weight at the second moment that is sent by a second base station to which a second cell belongs in a data transmission system, where the second cell includes a neighboring cell that meets a preset interaction condition and that is in a neighboring cell of the first cell; calculating a signal to interference plus noise ratio SINR of each user in the first cell at the second moment based on the first transmit weight and the second transmit weight; and selecting a target scheduling user at the second moment from the user in the first cell based on the SINR of each user at the second moment. In this application, a problem of currently low interference avoidance reliability is resolved. This application can be used for data transmission.

    摘要： 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. In this process, the server determines the second downlink sending weight of the second transmission point based on the first downlink sending weight of the first transmission point, so that when the electronic device receives data streams sent by transmission points in the coordinated set, receiving directions of different data streams are orthogonal or approximately orthogonal, thereby resolving a problem that interference between data streams of different transmission points is excessively large when the electronic device receives the data streams, and achieving an objective of correctly receiving data by the electronic device.

    摘要： Embodiments of the present invention disclose a beam avoidance method and a base station, and relate to the communications field, to resolve a problem of an increase in a probability of deterioration in performance of UE on which beam avoidance is performed in a coordinated cell. A specific solution is: determining, by a first base station, that first UE transmitting a service on a currently scheduled RB is benefited UE, where a cell in which the first UE is located is a first cell; determining, by the first base station, whether a user is satisfied with a service that is of second UE and that is transmitted on the currently scheduled RB, where a cell in which the second UE is located is a second cell, and the second cell is a cell adjacent to the first cell; and adjusting, by the first base station, a transmit weight of the second UE if the user is satisfied with the service that is of the second UE and that is transmitted on the currently scheduled RB. The embodiments of the present invention are used in a beam avoidance process.
