    Performance analysis of 60 GHz pulse multiuser communication system based on cross-layer strategy by Xuehua LI, Chen SHEN, Yuanyuan YAO

    Published 2018-09-01
    “…Due to the advantages of license-free,strong directionality,high system capacity,and high transmission rate of Gbit/s,60 GHz band is listed as one of the candidate bands for new radios (new radio).In 5G ultra-dense networking scenario,the randomness of node switching caused by the decrease of the distance between network nodes may cause severe multiple access interference and resource mismatch problems.In this regard,based on the concept of cross-layer collaborative design,a resource scheduling strategy based on fairness was proposed.The multiple access performance of the strategy was simulated in a 60 GHz pulsed wireless communication system based on TH-PAM (time hopping pulse amplitude modulation).Simulation results show that compared with the system with pure physical layer optimization algorithm,the multiple access system which adopts this strategy shows stronger fairness and lower system error rate,but it needs increase the transmission power to meet the requirements of the coverage of the equivalent communication system.That is,there is a certain trade-off between the energy and fairness of the system,which can be used to guide the structure and deployment of the actual communication system.…”

    Service-based network as a platform: research on a new information communication network architecture by Xiaoyun WANG, Xiaodong DUAN, Tao SUN

    Published 2023-01-01
    “…The deployment of 5G enables the network to expand from serving individuals to the industry.The evolution of mobile communication system was analyzed, and a new architecture development direction-service-based network as a platform was proposed.Facing the fundamental challenge of diversified requirements of industrial scenarios, the new architecture employed “platform” to address the generalization and scalability obstacles, and employed “service” to address heterogeneous characteristics of the network.The network service level assurance could also be guaranteed.The definition, overall architecture and mathematical model of “service-based network as a platform” were given.Based on the innovative practice of 5G service-based architecture (SBA) design, the principles of service design were proposed, and then the hierarchical design ideas were given.…”
