Positioning protocol enhancements for sidelink positioning

One or more processors configured to, when executing instructions stored in memory, perform operations comprising:

• instructing radio frequency (RF) circuitry to receive a positioning message over a sidelink interface between a first user equipment (UE) and a second UE;
• generating a response to the positioning message;
• and
• instructing RF circuitry to transmit the response to the second UE over the sidelink interface.

One or more processors configured to, when executing instructions stored in memory, perform operations comprising:

• instructing radio frequency (RF) circuitry to receive a positioning message over a sidelink interface between a first user equipment (UE) and a second UE, wherein the positioning message comprises at least one of a dedicated positioning message received over PC5-RRC, a broadcast positioning message received over PC5-S, or a positioning system information block (posSIB);
• generating a response to the positioning message;
• and
• instructing RF circuitry to transmit the response to the second UE over the sidelink interface.

A method, comprising:

• instructing radio frequency (RF) circuitry to transmit a positioning message over a sidelink interface between a first UE and a second UE;
• generating a response to the positioning message;
• and
• instructing RF circuitry to transmit the response to the second UE over the sidelink interface.
