Method to improve downlink prs positioning performance in presence of time slot misalignment
By identifying non-collision PRS symbols in LTE and 5G NR networks to determine TOA, the SNR degradation problem caused by misalignment is resolved, and the positioning accuracy of the UE is improved.

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 at least on the expected RSTD, a first portion of a reference signal from the TRP, where the first portion of the reference signal does not overlap in time with a non-reference signal from the reference cell at the UE. The method also includes determining a first time of arrival (TOA) of the reference signal from the TRP based on the first portion of the reference signal.
