  • Patent number: 11497001
    Abstract: A method for operating a real-time control system comprising a first system configured to generate an information signal and a second system configured to use the information signal, wherein the second system comprises a first buffer for storing a previously received information signal. The method comprising: transmitting, by the first system, a first communication packet comprising the first information signal and generating, by the second system, a predicted first information signal for use in the first time slot. The predicted first information signal being generated by: retrieving the previously received information signal from the first buffer; generating a first prediction using a short-term predictor; and concurrently generating a second prediction using a long-term predictor; and setting the predicted first information signal equal to the first prediction unless the second prediction is available.

  • Publication number: 20220104062
    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.

  • Publication number: 20210329653
    Abstract: In general terms, network resource allocation takes place within a wireless communication channel in which resource is defined with respect to time and frequency; a resource allocation process involves joint allocation of resource for communication to and from group of devices, to enable a cyclic exchange of information between the devices and a base-station and thus to enable wireless closed loop control of the device. By jointly allocating resources in one go, overheads are reduced thereby providing a more efficient resource allocation mechanism. Furthermore, bundled transmissions are scheduled, including repetitions of transmissions to increase the likelihood of transmission success. By determining a minimum bundle length required to meet a predefined threshold for received signal quality, the reliability of the transmissions can be ensured.
