    Frequency Resource Sharing and Allocation Scheme Based on Coalition Formation Game in Hybrid D2D-Cellular Network by Qing Ou, Rongqing Zhang, Xi Luan, Yuxin Cheng, Jun Wu, Jianjun Wu

    Published 2015-01-01
    “…A distributed cooperation scheme on frequency resource sharing is proposed to improve the quality of service (QoS) in device-to-device (D2D) communications underlaying cellular networks. Specifically, we formulate the resource allocation problem as a coalition formation game with transferable utility, in which all users have the incentive to cooperate with some others and form a competitive group to maximize the probability of obtaining their favorite spectrum resources. …”

    5G-Advanced E2E deterministic transmission analysis and system design by Haiyang SUN, Yi SHI, Yan LI, Qiang FAN, Xin MA

    Published 2022-03-01
    “…Because of the advantages of flexible deployment, low cable cost, strong support for mobility and comprehensive QoS control and high scalability, cellular networks had been widely used in factory scenarios.At the same time, the deterministic service in the factory also puts forward certain requirements for cellular network control.Therefore, in discussions related to 5G-Advanced, the industry also proposes to research a 5G cellular network that supports ultra-low latency.To meet the delay requirement of 2 ms, two key technologies, deterministic N3 interface and cross-layer scheduling optimization were proposed to reduce the transmission or waiting delay on the transport network and air interface.These two technologies were the enhancement based on the current communication mechanism and network protocol between cellular network and deterministic network.The high delay requirement of deterministic services can be met well without changing the existing network protocol too much.…”

    Call Admission Scheme for Multidimensional Traffic Assuming Finite Handoff User by Md. Baitul Al Sadi, Afsana Nadia

    Published 2017-01-01
    “…Usually, the number of users within a cell in a mobile cellular network is considered infinite; hence, M/M/n/k model is appropriate for new originated traffic, but the number of ongoing calls around a cell is always finite. …”

    A multi-hop D2D and social awareness based novel relay selection algorithm by Liang LI, Xinjie YANG

    Published 2022-08-01
    “…The social domain was introduced to multi-hop D2D (device-to-device) communication in cellular network scenarios, and a novel relay selection algorithm for multi-hop D2D communication under cellular network was proposed.Unlike existing relay selection algorithms, the proposed algorithm selects relays for each hop in reverse order, which reduces the signaling overhead caused by algorithm implement.Then, social domain information of mobile terminals was introduced to the algorithm and its influence on the algorithm’s performance was studied, which was found significant enough not to be overlooked hence providing useful guidance to designing algorithms in practical systems.Moreover, via extensive Monte Carlo simulations, it is discovered that the proposed algorithm outperforms the benchmarks in terms of data throughput and energy efficiency in absence of social relationship information.In a more practical implementation with social relationship information included, the proposed algorithm though naturally achieving less throughput, significantly outperforms the benchmarks in energy efficiency.…”

    Energy efficiency analysis of broadcast and communication converged network by Cheng-jie SHEN, Yun RUI, Guo-ming QIAN, Fei HUANG, Ming-qi LI

    Published 2014-05-01
    “…By further exploiting the coverage of broadcast network and the outage probability of cellular network, the closed-form expression of the converged network energy efficiency (EE) was derived, and the impact of popular business probability to the energy efficiency was discussed. …”
