Reducing the overhead of timestamps in positioning state information (PSI) reports

A method of wireless communication performed by a network entity, comprising:

• receiving, from a user equipment (UE) via low layer signaling, a value of at least one positioning measurement of at least one downlink positioning reference signal (DL-PRS), the value of the at least one positioning measurement received at a reception time during a positioning session between the network entity and the UE;
• determining a reference point for a timestamp for the at least one positioning measurement;
• and
• determining the timestamp based on the reception time, the reference point, and an offset, wherein the timestamp comprises an amount of time relative to the reference point that the at least one positioning measurement is valid.

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:
• perform at least one positioning measurement of at least one downlink positioning reference signal (DL-PRS) received from a transmission-reception point (TRP) during a positioning session;
• report, to a positioning entity, via the at least one transceiver, a value of the at least one positioning measurement via low layer signaling;
• and
• determine a timestamp for the at least one positioning measurement relative to a reference point, wherein the timestamp comprises an amount of time relative to the reference point that the at least one positioning measurement is valid, and wherein the timestamp comprises enough bits to specify a time of the at least one positioning measurement within a subset of slots within a given period of time during which DL-PRS are scheduled.
