Communication device and operating method thereof

A method of operating a communication device, comprising:

• enabling, by an ultra-wideband, UWB, communication unit of the communication device, UWB communication between the communication device and an external communication device;
• attempting, by a processing unit and a prioritization unit of the communication device, to synchronize and perform a ranging session between the communication device and the external communication device, wherein attempting to synchronize and perform the ranging session includes
• setting a dynamic priority of the ranging session to a base priority associated with the external communication device,
• after setting the dynamic priority to the base priority, making a determination that the dynamic priority should be increased based on one or more of
• a synchronization indicator indicating that the ranging session is not in a synchronized state, and
• a scheduling indicator indicating that the ranging session has not been scheduled,
• when the determination is made that the dynamic priority of the ranging session should be increased, increasing the dynamic priority of the ranging session for a predefined amount of time,
• when the predetermined amount of time has elapsed or when the scheduling indicator indicates that the ranging session has been scheduled, resetting the dynamic priority of the ranging session to the base priority;
• and
• when the scheduling indicator indicates that the ranging session has been scheduled, performing, by the processing unit, the ranging session between the communication device and the external communication device, wherein the ranging session comprises one or more distance measurements based on messages exchanged between the communication device and the external communication device, and wherein the messages are exchanged through the UWB communication unit.
