Abstract
A wireless transmit/receive unit (WTRU) and a method are described herein regarding preservation of positioning integrity associated with wireless systems. Using multiple positioning configurations and/or schemes (e.g., positioning reference signal (PRS) configurations/schemes), e.g., based on a switching pattern, may ensure integrity (e.g., adequate and/or robust integrity), for example, if error events (e.g., low reference signal received power, blockage of PRS from transmission/reception points (TRPs), etc.) have a persistent duration. The WTRU comprises a processor configured to receive a first, a second and a third subset of PRS configuration information, receive configuration information indicating error source information, a first switching pattern, and a positioning uncertainty threshold, perform a first set of measurements using the first switching pattern and the first and second subsets of PRS configuration information, determine a first positioning uncertainty based on the first set of measurements and the error source information, and send an indication indicating measurement information and positioning uncertainty information.
