Title:
METHOD FOR DETERMINING TIMING ADVANCE OF TERMINAL DEVICE, AND COMMUNICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/022601
Kind Code:
A1
Abstract:
Provided is a method for determining a timing advance of a terminal device. A terminal device determines a timing advance of the terminal device under a second satellite by means of acquiring a timing advance of the terminal device under a source satellite, frame alignment information of the source satellite, frame alignment information of a target satellite, and the difference between a round-trip delay of the terminal device with respect to the source satellite and a round-trip delay of the terminal device with respect to the target satellite, such that the terminal device can switch between satellites without random access, thereby improving the satellite switching efficiency and the user experience.
