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

A user equipment (UE), comprising:

• means for performing at least one positioning measurement of a first downlink positioning reference signal (DL-PRS) received from a first transmission-reception point (TRP) and a second DL-PRS received from a second TRP during a positioning session, wherein the first TRP is a reference TRP for the positioning session;
• and
• means for reporting, to a positioning entity via low layer signaling, a relative value of the at least one positioning measurement relative to an expected value of the at least one positioning measurement, wherein the relative value of the at least one positioning measurement is a difference between the expected value of the at least one positioning measurement and a measured value of the at least one positioning measurement, and wherein the expected value of the at least one positioning measurement comprises an expected reference signal time difference (RSTD) value for the first DL-PRS and the second DL-PRS.

A non-transitory computer-readable medium storing computer-executable instructions, which, when executed by a user equipment (UE), cause the UE to perform operations, the instructions comprising:

• at least one instruction to cause the UE to perform at least one positioning measurement of a first downlink positioning reference signal (DL-PRS) received from a first transmission-reception point (TRP) and a second DL-PRS received from a second TRP during a positioning session, wherein the first TRP is a reference TRP for the positioning session;
• and
• at least one instruction to cause the UE to report, to a positioning entity via low layer signaling, a relative value of the at least one positioning measurement relative to an expected value of the at least one positioning measurement, wherein the relative value of the at least one positioning measurement is a difference between the expected value of the at least one positioning measurement and a measured value of the at least one positioning measurement, and wherein the expected value of the at least one positioning measurement comprises an expected reference signal time difference (RSTD) value for the first DL-PRS and the second DL-PRS.
