A review of Time Sensitive Communication Technology

5G deterministic network is a new type of industrial communication technology vigorously promoted by the international industry. In 3GPP Rel-16 and Rel-17, time sensitive communication technology integrating 5G and TSN has been studied to facilitate deterministic transmission. Compared with URLLC, 3GPP further enhances the 5G network in terms of delay jitter and time synchronization to realize the end-to-end time sensitive communication. The paper analyzes characteristics of time sensitive communication technology. Based on the progress of time sensitive communication technology in 3GPP, the paper studies the network architecture and key technologies supporting time sensitive communication.
