Abstract
Disclosed are techniques for wireless communication. Aspects of the disclosure are directed to timing synchronization correction for position estimation based on TDOA (e.g., uplink TDOA, sidelink TDOA, etc.). In some aspects, a relative time of arrival (RTOA)-based calibration procedure is performed to determine a timing synchronization correction value to be applied to TDOA measurements between two wireless reception reference nodes. In further aspects, the synchronization correction value aspects is used in association with a TDOA-based position estimate of a target user equipment (UE) (e.g., at a location management function (LMF) for network-assisted positioning, or transmitted to target UE and used by the target UE for UE-based positioning).
