Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE determines multiple uplink measurement occasions for transmitting multiple reference signals to a satellite in a non-terrestrial network (NTN). The UE generates, based on Global Navigation Satellite System (GNSS) location data of the UE and ephemeris data of the satellite, multiple timing advance (TA) reports that are linked to the multiple uplink measurement occasions, respectively. The UE transmits the multiple TA reports to the satellite at multiple time points. The UE transmits the multiple uplink reference signals to the satellite on the uplink measurement occasions.

Abstract: Various solutions for enhancements on integer cycle report for carrier phase positioning are described. An apparatus may receive a positioning reference signal (PRS) from a first network node of a wireless network. The apparatus may measure a carrier phase associated with a delay path and a transmission frequency point of the PRS. Then, the apparatus may report the carrier phase to a second network node of the wireless network.

Abstract: Various solutions for an artificial intelligence/machine learning (AI/ML) positioning model using relative time input with respect to an apparatus in mobile communications are described. The apparatus may measure a first channel delay profile with a first path timing according to a first reference signal associated with a first network node. The apparatus may adjust the first path timing by a timing difference associated with a reference network node. The apparatus may: (1) generate a model output by a positioning model based on the first channel delay profile with the adjusted first path timing used as model inputs; or (2) report the first channel delay profile with the adjusted first path timing to a network.
