Title:
METHOD, DEVICE, AND SYSTEM FOR TIME SYNCHRONIZATION
Document Type and Number:
WIPO Patent Application WO/2024/065308
Kind Code:
A1
Abstract:
This disclosure relates generally to a method, device, and system for synchronization in a wireless network. One method performed by a wireless device is disclosed. The method may include receiving, from a first network element in a 5GS, a first message comprising clock configuration information, the clock configuration information comprising at least one of: a list of GM clocks comprising a first and a second GM clock; a clock indicator of each GM clock in the list of GM clocks; a time difference between the first GM clock and the second GM clock; receiving, from a second network element the 5GS, a first clock information for the first GM clock; in response to the first clock information, using the first GM clock as an active GM clock; and synchronizing with the 5GS based on the first clock information and treating the first GM clock as an active GM clock.
