Title:
DETERMINATION AND USAGE OF FRAME OF REFERENCE FOR NON-TERRESTRIAL NETWORK ORBITAL PARAMETERS IN MOBILE COMMUNICATIONS
Document Type and Number:
WIPO Patent Application WO/2023/185642
Kind Code:
A1
Abstract:
Various solutions for determination and usage of frame of reference for non-terrestrial network (NTN) orbital parameters in mobile communications are described. An apparatus (e.g., a UE) determines one or more orbital parameters defined in an inertial reference frame. The apparatus then performs NTN communications according to the one or more orbital parameters.
