Classification: CPC G  H | IPC G  H

Claim 5:
6. 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 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
a prioritization unit configured to prioritize 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 is configured to prioritize a specific one of the ranging sessions by changing a value of a priority parameter used by a scheduler of the communication node, and wherein, when a specific ranging session associated with said priority parameter collides or overlaps with at least one other ranging session in a given time slot, the scheduler is configured to schedule said specific ranging session if the priority parameter has a higher value than a priority parameter associated with the other ranging session.
