Abstract
A user equipment includes processor(s) configured to: obtain first acquisition assistance (AA) data by one or more receivers from a network; determine whether external coarse position injection (CPI) data, received by the one or more receivers from the network, exceed a reliability threshold; and in response to the one or more external CPI data exceeding the reliability threshold: calculate a horizontal error position estimate (HEPE) based on measurement(s) obtained according to second AA data, where the second AA data includes a subset of satellite vehicles from the first AA data; and determine a position of the user equipment based on the external CPI data and the HEPE.
Claims20
A user equipment, comprising:
- one or more receivers;
- one or more memories;
- and
- one or more processors communicatively coupled to the one or more memories and the one or more receivers, the one or more processors being configured to:
- obtain first acquisition assistance (AA) data by the one or more receivers from a network;
- determine whether one or more external coarse position injection (CPI) data, received by the one or more receivers from the network, exceed a reliability threshold;
- and
- in response to the one or more external CPI data exceeding the reliability threshold:
- calculate a horizontal error position estimate (HEPE) based on one or more measurements obtained according to second AA data, wherein the second AA data includes a subset of satellite vehicles from the first AA data;
- and
- determine a position of the user equipment based on the one or more external CPI data and the HEPE.
A method for determining a position of a user equipment, comprising:
- obtaining first acquisition assistance (AA) data from a network;
- determining whether one or more external coarse position injection (CPI) data received from the network exceed a reliability threshold;
- and
- in response to the one or more external CPI data exceeding the reliability threshold:
- calculating a horizontal error position estimate (HEPE) based on one or more measurements obtained according to second AA data, wherein the second AA data includes a subset of satellite vehicles from the first AA data;
- and
- determining a position of the user equipment based on the one or more external CPI data and the HEPE.
A non-transitory, processor-readable storage medium comprising processor-readable instructions to cause one or more processors to:
- obtain first acquisition assistance (AA) data from a network;
- determine whether one or more external coarse position injection (CPI) data received from the network exceed a reliability threshold;
- and
- in response to the one or more external CPI data exceeding the reliability threshold:
- calculate a horizontal error position estimate (HEPE) based on one or more measurements obtained according to second AA data, wherein the second AA data includes a subset of satellite vehicles from the first AA data;
- and
- determine a position of the user equipment based on the one or more external CPI data and the HEPE.
