Abstract
A method of transmission scheduling for one or more process devices in an industrial application, such as a sensor, an actuator and/or a process controller, capable of wireless communication, implemented by a radio control unit, is proposed, the method comprising: determining with respect to the industrial application whether a licensed shared access spectrum is available and assigning to the one or more process devices, based on a traffic type of the data to be transmitted by the one or more process devices, an access spectrum within the licensed shared access spectrum.
Claims16
A method of transmission scheduling for one or more process devices in an industrial application, capable of wireless communication, implemented by a radio control unit, the method comprising:
- determining a traffic type of data that is to be transmitted by the one or more process devices out of a plurality of traffic types;
- determining, with respect to the industrial application, whether a licensed spectrum is available;
- and
- upon determining that the licensed spectrum is not available, performing at least one of:
- assigning, to the one or more process devices, based on the traffic type of the data to be transmitted by the one or more process devices is of mid or low priority, an access spectrum within licensed shared access spectrum or unlicensed shared access spectrum;
- and
- assigning, to one or more process devices, based on the traffic type of the data to be transmitted by the one or more process devices is of high priority, an access spectrum within the licensed spectrum by clearing the licensed spectrum currently used by the industrial application that is of low priority.
A method of data transmission in an industrial application, implemented by a process device capable of wireless communication, the method comprising:
- determining a traffic type out of a plurality of traffic types of the data that is to be transmitted by the process device;
- determining need of an access spectrum for the wireless communication with the process device;
- transmitting information of the need the access spectrum to a radio control unit;
- receiving an assignment message from the radio control unit, the assignment message indicating whether a licensed spectrum is available;
- and
- performing the data transmission of the traffic type, within the access spectrum of the licensed spectrum, based on an access spectrum assignment for the process device, in the industrial application, obtained by the radio control unit,
- wherein when the assignment message indicates that the licensed spectrum is not available, performing the data transmission using one of licensed shared access spectrum and unlicensed shared access spectrum for the traffic type of data to be transmitted by the one or more process device is of mid or low priority;
- and
- performing the data transmission within the licensed spectrum for the traffic type of data to be transmitted by the one or more process device is of high priority.
