Classification: CPC G  H | IPC G  H

Claim 12:
13. A method of operating a communication node, comprising:
enabling, by an ultra-wideband, UWB, communication unit comprised in said communication node, UWB communication with a plurality of external communication nodes;
performing, by a processing unit comprised in said communication node, ranging sessions between the communication node and said external communication nodes, wherein said ranging sessions comprise one or more distance measurements based on messages exchanged between the communication node and said external communication nodes, wherein said messages are exchanged through the UWB communication unit; and
prioritizing, by a prioritization unit comprised in said communication node, said ranging sessions in dependence on at least one previously measured distance between the communication node and the respective external communication nodes, wherein prioritizing includes increasing the priority of a specific one of the ranging sessions, to be performed with a specific external communication node, when one or more previously performed distance measurements with the specific external communication node indicate that the distance between the communication node and the specific external communication node has decreased.
