Abstract
A method of user equipment (UE) positioning includes receiving positioning assistance data associated with a Transmission Reception Point (TRP), such as an expected Reference Signal Time difference (RSTD) between a reference cell and the TRP. The method also includes capturing, based on at least the expected RSTD, a first portion of reference signals from the TRP. The method further includes determining a first Time of Arrival (TOA) of the reference signals from the TRP based on the first portion of the reference signals.
Claims20
A method, at a User Equipment (UE), of positioning the UE comprising:
- receiving positioning assistance data associated with a Transmission Reception Point (TRP), the positioning assistance data including an expected Reference Signal Time difference (RSTD) between a reference cell and the TRP;
- capturing, based on at least the expected RSTD, a first portion of reference signals from the TRP;
- and
- determining a first Time of Arrival (TOA) of the reference signals from the TRP based on the first portion of the reference signals.
A device comprising:
- a transceiver;
- a memory;
- and
- one or more processors communicatively coupled with the transceiver and the memory and configured to:
- receive, via the transceiver, positioning assistance data associated with a Transmission Reception Point (TRP), the positioning assistance data including an expected Reference Signal Time difference (RSTD) between a reference cell and the TRP;
- capture, via the transceiver and based on at least the expected RSTD, a first portion of reference signals from the TRP;
- and
- determine a first Time of Arrival (TOA) of the reference signals from the TRP based on the first portion of the reference signals.
A device comprising:
- means for receiving positioning assistance data associated with a Transmission Reception Point (TRP), the positioning assistance data including an expected Reference Signal Time difference (RSTD) between a reference cell and the TRP;
- means for capturing, based on at least the expected RSTD, a first portion of reference signals from the TRP;
- and
- means for determining a first Time of Arrival (TOA) of the reference signals from the TRP based on the first portion of the reference signals.
