1. An apparatus for a wireless communication system, the wireless communication system comprising one or more base stations and a plurality of user devices, UEs,
wherein the apparatus is configured to be connected to one or more UEs via a sidelink for a sidelink communication with the one or more UEs, the apparatus and the one or more UEs forming a group of UEs and using a set of group resources to be used for the sidelink communication within the group of UEs,
wherein, in case a base station does not provide resource allocation configuration or assistance, the apparatus is configured to select resources from a set of resources provided by the wireless communication system so as to alter or completely change the set of group resources to be used for the sidelink communication within the group of UEs,
wherein, to select from the set of resources the resources to be used for the sidelink communication within the group of UEs, the apparatus is configured to carry out a sensing procedure or listening to announcements indicative of resources used by other UEs,
wherein the one or more UEs forming with the apparatus the group of UEs do not sense or select resources for the sidelink communication within the group of UEs but receive information about the resources for the sidelink communication from the apparatus, and
wherein the apparatus is configured to announce the sensed or selected resources for the sidelink communication to all group UEs.
