Semi-static scheduling resources are suitable for carrying the services of the Industrial Internet. However, when the burst dynamic scheduling services with higher priority of the Industrial Internet need to be sent and the time-frequency resources overlap between the services and the semi-static scheduling resources, the dynamic scheduling services need to preempt half of the time-frequency resources. Statically scheduled resources are used for data transmission. At this time, the low-priority semi-persistently scheduled data has to wait for the transmission opportunity of the semi-persistently scheduled service in the next cycle. If several consecutive semi-statically scheduled service transmission opportunities are occupied, it will seriously affect the QoS (Quality of Service, service quality) of the service.

In the prior art, the service corresponding to CG can request uplink resources by sending SR (Scheduling Request, uplink scheduling request) to the base station, and then send BSR (Buffer Status Report, buffer status report) MAC CE (Media Access Control Address Control Element, media access control layer control unit), and finally send the data by carrying data on the dynamic scheduling resource; or, by carrying the corresponding CG on the high priority PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel) resource The BSR MAC CE of the business.
