8. A first network function entity including a network side time sensitive network (TSN) translator (NW-TT) in a 5th generation system (5GS), the first network function entity comprising:
a transceiver configured to transmit and receive a signal; and
a controller coupled with the transceiver and configured to:
receive, from a second network function entity, time synchronization information including first information indicating the NW-TT to send sync message to a device-side TSN translator (DS-TT) in the 5GS and second information associated with a transport type for distribution of a time synchronization,
generate a sync message for the DS-TT based on the time synchronization information,
add, to the sync message, an ingress timestamp corresponding to an ingress time when the sync message is generated, and
transmit, to a terminal including the DS-TT, the sync message,
wherein the sync message further includes a rate ratio with a value set to 1.
