Classification: CPC G  H | IPC G  H

Claim 14:
15. A method of operating a communication node, comprising:
enabling, by an ultra-wideband, UWB, communication unit comprised in the communication node, UWB communication with a plurality of external communication nodes;
performing, by a processing unit comprised in the communication node, ranging sessions between the communication node and the external communication nodes, wherein the ranging sessions comprise one or more distance measurements based on messages exchanged between the communication node and the external communication nodes, wherein the messages are exchanged through the UWB communication unit; and
prioritizing, by a prioritization unit comprised in the communication node, the ranging sessions in dependence on at least one previously measured distance between the communication node and the respective external communication nodes, wherein the prioritization unit compares the previously measured distance against at least one predefined range of distances, and changes the priority of the ranging sessions if the previously measured distance falls within said predefined range.
