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), the apparatus comprising:
one or more antennas or an antenna array having a plurality of antennas, a signal processor, and a transceiver;
wherein the apparatus is configured to be connected to one or more UEs via a sidelink for a sidelink communication with one or more of the plurality of 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 the apparatus is a leader UE of the group formed by the apparatus and the one or more UEs, and
wherein in case the base station does not provide resource allocation configuration or assistance, the leader UE is configured to send, responsive to a demand for resource allocation information for the sidelink communication within the group of UEs or in an event-triggered manner, a group resource reservation announcement exclusively sensed or selected by the leader UE from the set of resources, the group resource reservation announcement to be used for the sidelink communication within the group of UEs.
