1. A method performed by a User Equipment (UE) in a cellular communications system or a Time Sensitive Networking (TSN) Translator (TT) associated with the UE, the method comprising:
receiving, from a TSN end station, a Precision Time Protocol (PTP) or Generalized PTP (gPTP) announce message comprising information, the information identifies one or more clock domains, wherein the identified one or more clock domains are domains for which the TSN end station desires to receive PTP or gPTP messages; and
sending, to a core network node in the cellular communications system the information that identifies the one or more clock domains extracted from the PTP or gPTP announce message.
