MCS Analysis for 5G-NR V2X Sidelink Broadcast Communication

Abstract: Leveraging Modulation and Coding Schemes (MCS) in 5G New Radio (NR) Sidelink represents one key strategy to provide sufficient capacity required by future 5G for Vehicle-to-Everything (V2X) services for intelligent vehicles. Early studies either directly adopt the previously optimised QPSK 1/2 by 802.11p/C-V2X or suggest an optimal MCS value under a particular context. In this paper, we identify a MCS value optimal under any context, by evaluating the impact of MCS on V2X broadcast communication considering multiple varying parameters (e.g. variable packet size, transmit rate or density) representative of different 5G V2X services.

Design and implementation of North China power dispatch data network

Abstract: To ensure the operation of the North China Power Grid safely,economically and qualitatively,it needs to establish and put North China power dispatch data network into operation.According to the three-tier network structure,the core and backbone layers adopt ring structure,the access layer adopts double star structure.It sets the network management center in the dispatching and communication center,runs the network and operations management uniformly.With three hierarchy and IP technology adopted and data communication network with high bandwidth and performance constructed on the highly reliable optical fiber transport channel,the North China power dispatch data network can meet the requirement of related business for data transmission.The design of the data network is analyzed in the aspects of network topology,IP layout,MPLS VPN,network security,and network management.

Performance Analysis of 4G LTE Sidelink Communication applied in Railway System

Abstract: The Wireless Train Backbone (WLTB) is an evolution of the Ethernet Train Backbone (ETB) that permits direct consist-to-consist communications in wireless technology. Although current internal train communications are mostly reliant on wired networks, in order to offer harmonised inter-operability connection with other train to ground communication applications, it is essential to integrate wireless communication into WLTB. Since 4G LTE technology is currently most widely deployed over all type of applications due to its maturity and its efficient radio access management, this can be a solution for this issue. In this study we analyze the performance of LTE Sidelink communication under different realistic based scenarios for WLTB by implement related scenarios and simulate in a ns3-based simulator. The goal of this analysis is to highlight the capability that LTE V2X SL communication support and also demonstrate the difficulties it experiences under challenging circumstances. Obtained results indicate that 4G LTE is a potential technology for end devices communication in the train communicatoin, however performance suffers under certain rigorous situations.

On the Feasibility of URLLC for 5G-NR V2X Sidelink Communication at 5.9 GHz

Abstract: Delivering ultra-reliable low-latency communication (URLLC) services on 5G New Radio (NR) is critical for extended Vehicle-to-everything (V2X) applications. Early studies focused either on infrastructure V2X communications, or exclusively evaluating performance on mm Wave band, but never so far for V2X Sidelink communications. In this paper, we evaluate the feasibility of achieving URLLC critical requirements for 5G NR V2X Sidelink communication at the V2X 5.9 GHz band. We propose a higher 5G-NR numerology completed by a deterministic scheduler and propose an analytical V2X SL admission control algorithm to reach tight URLLC requirements.

Study on reliability of a novel Electric Power Data Network for smart grid

Abstract: In recent years, with the proposal of strong and smart grid, the reliability requirements of the Electric Power Data Network are getting higher and higher. Based on the background, this paper proposes a novel Electric Power Data Network for the smart grid. After that a comparative analysis on the information congestion degree is provided between the novel Electric Power Data Network based on artificial spider web topology and the traditional Electric Power Data Network based on the star topology. The results show that the Electric Power Data Network using the artificial spider web topology has a higher reliability.

Research of test models of electric power dispatching data network

Abstract: With the size and service applications of electric power dispatching data network expanded gradually, types of router device accessed are also increasing. Technical requirements of devices networking characteristics, performance, and compatibility play important roles at the safe and stable operation of the dispatching data network. Performance, compatibility, and networking test models are proposed in this paper, which based on an analysis of the service types, network structure of dispatching data network and the development of routers. It is proved by practices that, these test models cover the entire service application scenarios of the current dispatching data network, futher standardizing network equipment access tests to the dispatching data network and promoting product upgrade and continuous improvement.
