Patent ID: 11564123

Abstract:
Arrangements described herein allow integration of TSN and wireless systems (e.g. 5G systems) by forming a virtual bridge over the wireless system. A two-level scheduling scheme is provided, where data is mapped into separate virtual queues based on the respective priority of the data. Each virtual queue is given a permission to allocate transmission resources (e.g. timeslots) at certain windows in accordance with a schedule. During each window, transmission resources are then allocated for the respective queue from a set of transmission resources. By applying two levels of scheduling (scheduling when to schedule), different scheduling rules can be applied for different priority data (different virtual queues). In addition, higher priority data can be scheduled with a higher priority (e.g. before the scheduling of lower priority data). This allows minimum performance criteria for certain types of data (certain Quality of Service data flows) to be guaranteed across the wireless system.
