description To control time synchronisation in a wireless network, the user equipment (UE) determines synchronisation requirements and, based on these requirements, sends a control message to the base station to control a time synchronisation process between the UE and the base station. In a second aspect of the invention, the base station determines the synchronisation requirements and sends the control message to the UE. The synchronisation requirements include whether synchronisation is required, and whether path delay compensation is required. The control message may be sent in response to receiving a message from a core network entity, and may include a duration time for which the synchronisation process is to be active. The message from the core network entity may enable a Device Side Time Sensitive Network Translator (DS-TT) function associated with the UE. It may also be associated with a PDU session and indicate whether the session is for Time Sensitive Communication (TSC) for a Time Sensitive Network (TSN) application.
