    Task offloading and resource allocation in NOMA-based ultra-dense MEC networks by Yun SHENG, Chen XU, Guangyuan ZHENG

    Published 2022-02-01
    “…In order to improve spectrum efficiency and meet the service demands of massive users, a non-orthogonal multiple access (NOMA)-based ultra-dense mobile edge computing (MEC) system was considered.In order to solve the serious communication interference caused by simultaneous offloading of multiple users and make efficient use of edge server resources, a joint task offloading and resource allocation scheme was proposed to minimize the system energy consumption while meeting the quality of service (QoS) of all users.Offloading decision, power control, computation resource and subchannel resource allocation were jointly considered in the proposed scheme.Simulations results show that the proposed scheme can efficiently lower system energy consumption compared to the other offloading schemes.…”

    Wireless ultra-reliable and low-latency communication:key design analysis and challenge by Yusun FU, Genke YANG

    Published 2020-08-01
    “…The current fragmented ultra reliable and low latency communication (URLLC) research focusing on a certain point was overcome.From the perspective of panoramic view,starting from the application scenarios and requirements,the system architecture,key technologies and solutions of URLLC were analyzed and introduced.Then,the physical layer detection performance requirements,link adaptation,radio resource management,end-to-end diversity solutions and how to integrate with TSN (time sensitive network) were analyzed in depth,and possible candidates were discussed.It hopes to have a thorough and comprehensive understanding of the theoretical research and application of URLLC,and a clear understanding of its challenges,so as to play a key reference for researchers and engineers in the related fields.…”
