RAN Enhancement to Support Propagation Delay Compensation of TSN

Abstract

The development of industrial automation processes enables new use cases that have stringent requirements for communication systems. The integration and deployment of time-sensitive networks (TSN) and fifth-generation mobile communication system (5G) is introduced to meet the high demands of industrial applications and achieve deterministic connection. Since time synchronization is the basis of both TSN and 5G system (5GS), R17 has enhanced time synchronization for the improved synchronization accuracy requirement. This paper introduces three baseline scenarios, Uu interface time synchronization budget, error terms, and two main propagation delay compensation options in R17.
