Zusammenfassung:	A method of communication in an intelligent transport system, ITS, to be carried out at a vulnerable road user, VRU, ITS station, VRU ITS-S, belonging to a cluster of VRUs. The method comprises determining that the VRU cluster has been reported in a collective perception message, CPM and setting an operating mode of the VRU ITS-S to a VRU passive mode, comprising refraining the VRU ITS-S from broadcasting VRU awareness messages, VAMs, for a time period. The VRU ITS-S may be set to passive in response to checking if the VRU is contained within a group of VRUs identified in the CPM. The VRU ITS-S may change from passive to active cluster leader mode based on a predetermined event, such as determining the VRU cluster is no longer reported in the CPM. The method may reduce the number of VAMs transmitted after breaking up a cluster upon determined the cluster is reported in a CPM.
