Abstract

Systems and methods to enable 5G system support for conveying time synchronization are provided. In some embodiments, a method performed by a wireless device for conveying external time domain information is provided. The method includes receiving a message in a first time domain used by the wireless device, the message comprising external time domain information; determining information about a second time domain based on the external time domain information; and conveying information about the second time domain to another node. In some embodiments, timing information is included into a GPRS Tunneling Protocol (GTP) payload, and the wireless device can get timing information directly from the data payload. This minimizes the RAN and/or gNB impact and adds the potential for multiple time domain support.
