1. A communication node, comprising:
an ultra-wideband, UWB, communication unit configured to enable UWB communication with a plurality of external communication nodes;
a processing unit configured to perform 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
a prioritization unit configured to prioritize said 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 is configured to increase 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.
