Reducing the overhead of reporting measurements and transmission-reception point (trp) identifiers in positioning state information (psi)

A method of wireless positioning performed by a user equipment (UE), comprising:

• performing at least one positioning measurement of at least one downlink positioning reference signal (DL-PRS) received from at least one transmission-reception point (TRP) during a positioning session;
• transmitting, to a positioning entity via low layer signaling, a positioning report including a value of the at least one positioning measurement;
• reporting, to the positioning entity, a quality metric step size that applies to all positioning measurements in the positioning report;
• and
• reporting, to the positioning entity via the low layer signaling, a quality metric for the at least one positioning measurement, wherein a field in the low layer signaling representing the quality metric does not include a quality metric step size for the quality metric.

A user equipment (UE), comprising:

• a memory;
• at least one transceiver;
• and
• at least one processor communicatively coupled to the memory and the at least one transceiver, the at least one processor configured to:
• receive, from a positioning entity, via the at least one transceiver, positioning assistance information comprising a plurality of transmission-reception points (TRPs);
• report, to the positioning entity, via the at least one transceiver, a subset of the plurality of TRPs;
• perform at least one positioning measurement of at least one downlink positioning reference signal (DL-PRS) received from at least one TRP of the subset of the plurality of TRPs;
• and
• report, via the at least one transceiver, to the positioning entity via low layer signaling, an identifier of the at least one TRP relative to the subset of the plurality of TRPs.
