METHOD TO IMPROVE DOWNLINK PRS POSITIONING PERFORMANCE IN PRESENCE OF SLOT MISALIGNMENT

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...

Zusammenfassung: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, where, at the UE, the first portion of the reference signals does not overlap in time with non-reference signals from the reference cell. 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.
