Position estimation using stale satellite vehicle position data

A position information provision method comprising:

• determining, at a user equipment (UE), first estimated locations of a first plurality of satellite vehicles based on first satellite vehicle position information that has exceeded a first expiration time of the first satellite vehicle position information;
• determining, at the UE, a first position estimate based on the first estimated locations of the first plurality of satellite vehicles, and first measurements of first satellite vehicle signals received by the UE;
• and
• transmitting, from the UE to a network entity, the first position estimate, a first indication of the first plurality of satellite vehicles from which signals were used to determine the first position estimate, a second indication of the first satellite vehicle position information used to determine the first position estimate, and a third indication of a first time corresponding to the first position estimate;
• wherein determining the first estimated locations of the first plurality of satellite vehicles comprises extrapolating, at the UE, satellite vehicle paths indicated by the first satellite vehicle position information.

A user equipment (UE) comprising:

• means for determining first estimated locations of a first plurality of satellite vehicles based on first satellite vehicle position information that has exceeded a first expiration time of the first satellite vehicle position information;
• means for determining a first position estimate based on the first estimated locations of the first plurality of satellite vehicles, and first measurements of first satellite vehicle signals received by the UE;
• and
• means for transmitting, to a network entity, the first position estimate, a first indication of the first plurality of satellite vehicles from which signals were used to determine the first position estimate, a second indication of the first satellite vehicle position information used to determine the first position estimate, and a third indication of a first time corresponding to the first position estimate;
• wherein the means for determining the first estimated locations of the first plurality of satellite vehicles comprises means for extrapolating satellite vehicle paths indicated by the first satellite vehicle position information.

A non-transitory, processor-readable storage medium comprising processor-readable instructions to cause one or more processors of a user equipment (UE) to:

• determine first estimated locations of a first plurality of satellite vehicles based on first satellite vehicle position information that has exceeded a first expiration time of the first satellite vehicle position information;
• determine a first position estimate based on the first estimated locations of the first plurality of satellite vehicles, and first measurements of first satellite vehicle signals received by the UE;
• and
• transmit, to a network entity, the first position estimate, a first indication of the first plurality of satellite vehicles from which signals were used to determine the first position estimate, a second indication of the first satellite vehicle position information used to determine the first position estimate, and a third indication of a first time corresponding to the first position estimate;
• wherein the processor-readable instructions to cause the one or more processors to determine the first estimated locations of the first plurality of satellite vehicles comprise processor-readable instructions to cause the one or more processors to extrapolate satellite vehicle paths indicated by the first satellite vehicle position information.
