Sidelink ranging and multilateration

A system, comprising:

• 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 mute at least one transmission on at least one of the resources allocated to the transceiver following the first resource to achieve at least one muted resource;
• wherein the second resource is one of the at least one muted resource;
• and
• the other transceiver, wherein the other transceiver is configured to transmit the second signal responsive to the reception of the first signal, wherein the other transceiver is configured to transmit the second signal on the second resource using the period based on which the resources are allocated to the transceiver.

A method for determining a distance between a first transceiver and a second transceiver of a wireless communication system, the first transceiver and the second transceiver communicating with each other using resources of a sidelink resource pool allocated to the first transceiver on a period basis with equal length periods and allocated to the second transceiver on a period basis with equal length periods, the method comprising:

• transmitting, by the first transceiver, a first signal on a first resource of the resources allocated to the first transceiver;
• muting at least one transmission on at least one of the resources allocated to the transceiver following the first resource, to obtain at least one muted resource;
• transmitting, by the second transceiver, a second signal responsive to the reception of the first signal, wherein the second signal is transmitted by the second transceiver on a second resource using the period based on which the resources are allocated to the first transceiver, wherein the second resource is one of the at least one muted resource;
• receiving, by the first transceiver, the second signal transmitted by second transceiver;
• and
• determining a distance between the first transceiver and the second transceiver based on a time between the transmission of the first signal by the first transceiver and the reception of the second signal by the first transceiver, and based on the period based on which the resources are allocated to the first transceiver,
• wherein the second resource is one of the resources allocated to the transceiver following the first resource.
