1. A transceiver for a wireless communication system,
wherein the transceiver is configured to communicate with at least one other transceiver of the wireless communication system using a sidelink resource pool of the wireless communication system;
wherein the transceiver is configured to transmit signals on resources of the sidelink resource pool that are allocated to the transceiver on a period basis with equal length periods tperiodA;
wherein the transceiver is configured to transmit a first signal on a first resource of the resources allocated to the transceiver;
wherein the transceiver is configured to receive a second signal from another transceiver of the wireless communication system on a second resource, the second signal transmitted by the other transceiver responsive to a reception of the first signal, wherein the second signal is transmitted by the other transceiver on the second resource using the period tperiodA based on which the resources are allocated to the transceiver;
wherein the transceiver is configured to determine a distance to the other transceiver based on a time troundA between the transmission of the first signal and the reception of the second signal from the other transceiver, and based on the period tperiodA based on which the resources are allocated to the transceiver;
wherein the second resource is one of the resources allocated to the transceiver following the first resource,
wherein the transceiver is configured to communicate with two or more other transceivers of the wireless communication system using the sidelink resource pool of the wireless communication system;
wherein the transceiver is configured to transmit a configuration message to the two or more other transceivers, wherein the configuration message comprises a resource pattern indicating one or more second resources selected out of the resources allocated to the transceiver;
wherein the transceiver is configured to receive second signals from the two or more other transceivers, wherein the second signals are transmitted by the two or more other transceivers responsive to a reception of the first signal, wherein the second signals are transmitted by the two or more other transceivers on one or more second resources using the period tperiodA based on which the resources are allocated to the transceiver;
wherein the transceiver is configured, to determine distances to the two or more other transceivers based on times troundA between the transmission of the first signal and the reception of the second signals from the two or more other transceivers, and based on the period tperiodA based on which the resources are allocated to the transceiver.
