    5G-Advanced: network-controlled repeater by Nan ZHANG, Ziyang LI, Ruyue LI, Wei CAO

    Published 2022-09-01
    “…Radio frequency (RF) repeaters have been deployed in 2G, 3G and 4G to improve the coverage of cellular system.While it is treated as a cost effective solution to extend the network coverage, conventional RF repeaters simply perform amplify-and-forward operation based on the set-up without the capability of doing flexible adjustments based on control and scheduling indication from network.An overview on the new study item in 5G-Advanced was given, i.e.network-controlled repeater.As an enhancement over conventional RF repeaters, network-contrdled repeater will enable the repeater to receive and process repeater control information from the network and perform its amplify-and-forward operation in a more efficient manner including the directive forwarding of the signal, dynamic on-/off of transmissions and receptions, and simplified network integration.…”

    Planning approach of survivable fiber-wireless broadband access network by Hongjun TAN, Yamin XIE, Yejun LIU

    Published 2016-05-01
    “…The emerging fiber-wireless(FiWi)broadband access network provides not only the new technological references for flexible broadband access anywhere and anytime,but also the research opportunities for the cost-efficient design of survivable broadband access network.The study of survivable FiWi access network planning was focused on,and an approach of survivable network planning based on wireless-rerouting protection was proposed.When any fiber link cuts,the failed optical network unit(ONU)can transfer its traffic into other normal ONUs.Solving the joint optimization problem of wireless routers placement,backup radios configuration and ONU capacity allocation was put more importance on,aiming to fully protect all traffic with the minimum deployment cost.The method of integer linear programming was employed to obtain the optimal solution for small-scale network planning.The heuristic algorithm was also proposed for the large-scale network planning.Simulation results demonstrate the effectiveness of the proposed approach in reducing network deployment cost.…”
