4. A wireless communication system, comprising:
one or more base stations, and
one or more user devices, UEs, the one or more UEs comprising:
an antenna; and
a signal processor,
wherein the user device that is served by one of the one or more base stations, a coverage area of the base station comprising one geographical zone or a plurality of geographical zones, and each geographical zone having mapped thereto a resource pool,
wherein the user device is to perform a measurement of resources of the resource pool for the geographical zone in which the user device is located, for determining whether a resource of the resource pool is used or unused,
wherein, responsive to a request from the base station, the signal processor is to create, using the measurement, a zone occupancy report for the geographical zone in which the user device is located, the zone occupancy report indicating an occupancy status of the resource pool mapped to the geographical zone, the zone occupancy report being returned to the base station via the antenna,
wherein the zone occupancy report comprises one or a combination of the following:
(i) a resource vector giving the occupancy for resource blocks of the resource pool,
(ii) a predefined number of resources of the resource pool,
wherein
(i) the resource vector indicates a percentage of occupancy per set of physical resource blocks, PRBs, or indicates the free PRBs, and
(ii) the predefined number of resources per resource pool are top-m resource blocks based on a statistic of the least occupied PRBs or the PRBs comprising the lowest received power,
wherein the user device is to operate in accordance with a first mode, the V2X Mode 4, for a sidelink communication with one or more other user devices, wherein in the first mode the user device is in a non-connected state and is to schedule resources for the sidelink communication autonomously,
wherein the user device, when in a coverage area of a transceiver of the wireless communication system, is to switch from the first mode to a second mode, the V2X Mode 3, in case one or more predefined criteria are met by the user device, and
wherein, in the second mode, scheduling of resources for the sidelink communication with the one or more other user devices is performed by the transceiver.
