    Abstract: According to a scheduling method and apparatus in a communication system, and a storage medium, a communication device obtains system status information, where the system status information includes network status information; obtains a scheduling policy based on the system status information and a deep neural network; and performs communication according to the scheduling policy. The deep neural network is obtained through training based on historical system status information, and the historical system status information includes system status information in all scheduling periods before a current scheduling period. Therefore, the scheduling policy obtained based on the deep neural network can meet a balancing requirement of throughput and fairness and solves a problem of low performance of an existing communication system.

    Abstract: This application provides a scheduling method and apparatus. The method includes: a network device uses a scheduling model applicable to K users for one or more times, and determines a scheduled terminal device based on scheduling weights output by the scheduling model for one or more times. Each time the scheduling model is used, status information of K terminal devices in n to-be-scheduled terminal devices is input to the scheduling model, and the scheduling model outputs scheduling weights respectively corresponding to the K terminal devices, where K is an integer greater than 1, and n is an integer greater than K. Therefore, regardless of a quantity of to-be-scheduled terminal devices in a communication system, the network device may reuse the scheduling model without re-establishing a scheduling model, so that the scheduling model is expandable and applicable to scenarios in which quantities of to-be-scheduled terminal devices are different.

    Abstract: The disclosure provides a channel state information processing method and an apparatus related to the communication field. The channel state information processing method includes: a first communication apparatus determines a first graph model corresponding to first channel state information. The first channel state information is channel state information from a second communication apparatus to the first communication apparatus. Then, the first communication apparatus processes the first graph model through a first neural network, to obtain first information. The first information is for the second communication apparatus to restore the first channel state information. Finally, the first communication apparatus sends the first information to the second communication apparatus.
