Apparatus and method for synchronization using wireless communication network in wireless communication system

A method performed by a base station, in a 5th generation system (5GS) as a time sensitive networking (TSN) bridge, the method comprising:

• receiving, from a session management function (SMF), N2 session management (SM) information including information on at least one QoS parameter associated with a TSN;
• and
• performing a scheduling based on the N2 SM information including the information on the at least one QoS parameter associated with the TSN,
• wherein the at least one QoS parameter associated with the TSN includes a packet delay budget (PDB) parameter associated with a backhaul delay between the base station and user plane function (UPF), and
• wherein an air delay of the base station is determined by subtracting the backhaul delay from a value of the PDB parameter.

A session management function (SMF), in a 5th generation system (5GS) as a time sensitive networking (TSN) bridge, comprising:

• at least one transceiver;
• and
• at least one processor operably coupled to the at least one transceiver and configured to:
• obtain at least one quality of service (QoS) parameter associated with a TSN, and
• transmit, to a base station, N2 session management (SM) information including information on the at least one QoS parameter associated with the TSN,
• wherein the at least one QoS parameter includes a packet delay budget (PDB) parameter associated with a backhaul delay between the base station and user plane function (UPF),
• wherein an air delay of the base station is determined by subtracting the backhaul delay from a value of the PDB parameter, and
• wherein the PDB parameter associated with the backhaul delay is used to a scheduling by the base station.
