Title:
METHOD AND DEVICE FOR UPDATING REFERENCE LOCATION IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/034958
Kind Code:
A1
Abstract:
A method by which a terminal updates a reference location on the basis of non-terrestrial networks (NTN) in a wireless communication system, may comprise the steps of: obtaining reference location-related information from a base station; determining whether the distance between the terminal and the reference location is less than a distance threshold on the basis of the reference location-related information, wherein if the distance between the terminal and the reference location is less than the distance threshold, measurement for cell reselection is not performed, and if the distance between the terminal and the reference location is greater than the distance threshold, the measurement for cell reselection is performed; and if the distance between the terminal and the reference location is less than the distance threshold, updating the reference location on the basis of a timer related to the reference location.
