  • Patent number: 11317431
    Abstract: The present invention discloses a method for receiving scheduling information, comprising steps of: receiving Downlink Control Information (DCI); and determining, according to a mapping relationship between configured transmission resources used for a Physical Uplink Shared Channel (PUSCH) and scheduling information in the DCI, scheduling information corresponding to the PUSCH in the DCI. Compared with the prior art, in the present invention, the scheduling information in the DCI is determined by the mapping relationship between the configured transmission resources used for transmitting the PUSCH by a UE and the scheduling information in the DCI, so that a base station can schedule all UEs for which there is a mapping relationship between PUSCH configured transmission resources and the scheduling information in DCI by sending only one piece of DCI. The scheduling overhead is reduced, the resource waste is reduced, and the efficiency of scheduling terminals by a communication system is significantly improved.

  • Publication number: 20210216685
    Abstract: Embodiments of this application disclose a data reporting method and a related device. After obtaining a sampled-data set, a network device (or a network management device) uses a part of sampled data in the sampled-data set to train each model in a model set to obtain a value of a parameter included in each model, and uses the other part of sampled data in the sampled-data set to verify each model to obtain a model (that is, a first model) corresponding to a smallest deviation. Then, the network management device can predict a trend status of true monitoring data on the network device only based on the first model and a value of a parameter included in the first model, and the network device reports only an identifier of the first model and a value of a corresponding parameter in the first model.
