Timing relationship enhancements for assistance data for non-terrestrial network positioning

An apparatus for wireless communication at a user equipment (UE), comprising:

• a memory;
• a transceiver;
• and
• at least one processor communicatively connected to the memory and the transceiver, the at least one processor configured to:
• receive, from a non-terrestrial network (NTN) base station, a scheduling offset that is associated with the NTN base station;
• and
• receive, from a network entity, one or more of:
• a set of expected reference signal time difference (RSTD) values associated with the NTN base station,
• a set of compensation factors associated with the set of expected RSTD values,
• a set of uncertainty values associated with the set of expected RSTD values,
• a set of expected downlink (DL)-angle of departure (AoD) values or DL-AoD uncertainties associated with the NTN base station, or
• a set of expected angle of arrival (AoA) values or AoA uncertainties associated with the NTN base station,
• wherein the one or more of the set of expected RSTD values, the set of compensation factors, the set of uncertainty values, the set of expected DL-AoD values or DL-AoD uncertainties, or the set of expected AoA values or AoA uncertainties are derived based at least in part on the scheduling offset.

An apparatus for wireless communication at a network entity, comprising:

• a memory;
• a transceiver;
• and
• at least one processor communicatively connected to the memory and the transceiver, the at least one processor configured to:
• configure a non-terrestrial network (NTN) base station to transmit one or more positioning reference signals (PRSs) to a user equipment (UE);
• and
• transmit, to the UE, assistance data (AD) associated with the NTN base station, the AD comprising multiple sets of parameters that correspond to a plurality of time durations.
