Research on 5G-TSN joint scheduling mechanism based on radio channel information
Published 2021-12-01“…To solve the deterministic transmission problem of periodic and time-triggered industrial traffics in wireless environment, a joint optimization mechanism of 5G and time sensitive networking based on radio channel information was considered.Based on improved traffic process architecture in time sensitive network, the traffics bearing on radio channel with worse quality could be processed in priority.In 5G networks, the relationship among radio channel quality, resource numbers and the maximum transmission times over radio was modeled, and the maximum transmission times satisfied data transmission reliable probability could be computed from the model,then the transmission time budget in 5G system for multiple industrial traffics bearing on diverse radio resources could be adjusted dynamically by retransmission factors.Simulation results demonstrate that the proposed joint scheduling mechanism achieves less TSN transmission delay of industrial traffics bearing on worse quality radio resources and can eliminate jitter caused by retransmission due to variation of 5G radio channel, which can guarantee end-to-end deterministic delay for industrial traffics.…”

Network information exposure based QoS prediction in tele-operated driving
Published 2023-03-01“…The rapid development of 5G systems supports the stringent quality of service (QoS) requirements for many Internet of vehicles (IoV) use cases.However, there are still many problems in the adaptation of networks and applications.Network information exposure is a potential solution that also enables the network to provide real-time cellular wireless network information to applications, thereby helping service providers achieve better policy control and achieve an experience for users.A predictive QoS (PQoS) method based on network information exposure was proposed.Applications could respond in advance and improve users’ quality of experience (QoE) by predicting upcoming network changes.Firstly, the background of network information exposure and PQoS was introduced, and the research, standards, and implementation status of PQoS both at home and abroad were introduced.Then, a QoS prediction method based on network information exposure in tele-operated driving (ToD) was proposed, and experiments were carried out through actual test data and the feasibility of PQoS was verified through the evaluation and analysis.The results show that the QoS prediction based on the network information exposure can well support the application of some IoV, including 5G remote driving, which provides a reference for implementing the 5G system in the smart transportation industry.…”
