Systems and methods for limiting a message size for a positioning protocol

A method at a user equipment (UE) for limiting a quantity of signaling for a location session with a location server (LS), the method comprising:

• receiving, from the LS, a first message for a positioning protocol, wherein the first message comprises an indication of a signaling quantity limit for the location session, wherein the signaling quantity limit indicates a message size limit for the positioning protocol;
• determining a second message for the positioning protocol, wherein the determination is based, at least in part, on the signaling quantity limit;
• and
• sending the second message to the LS.

A location server (LS) comprising:

• a communication interface;
• a memory;
• and
• a processing unit communicatively coupled with the communication interface and memory and configured to:
• obtain, via the communication interface, a coverage enhancement level for a user equipment (UE);
• determine, based at least in part on the coverage enhancement level, a signaling quantity limit for a location session with the UE, wherein the signaling quantity limit indicates a message size limit for a positioning protocol;
• and
• send to the UE, via the communication interface, a first message for the positioning protocol, wherein the first message comprises the signaling quantity limit.
