摘要

作为未来5G网络的基础,设备对设备(D2D)通信被认为是适合车载通信的平台。这方面的关键是智能无线电资源管理(RRM),它需要在车辆传输的可靠性和延迟方面提供足够的服务质量。基于通道状态信息(CSI)构建的经典方法被认为由于获取上述信息而具有很高的管理开销。因此,也出现了依赖于例如位置信息的其他RRM方案。然而,这种方案在无线电资源重用方面比较保守,频谱效率较低。在本文中,我们比较了车辆D2D底层网络的两种RRM方案的性能-基于csi的方案和基于位置的方案,就其所需的测量开销而言,以及对各自类别的一般方案的影响。

On the overhead of radio resource management schemes for mobile underlay D2D communication
Device-to-Device (D2D) communications as an underlay to future 5G networks is being considered as a suitable platform for vehicular communication. Key in this regard is intelligent Radio Resource Management (RRM), which needs to provision adequate quality of service, in terms of the reliability and latency of vehicular transmissions. The classical approach building upon Channel State Information (CSI) is assumed to have high management overhead due to the acquisition of the said information. Hence, alternative RRM schemes, which rely on, e.g., location information, have also emerged. Such schemes, however, are more conservative in regards to the reuse of radio resources and have lower spectral efficiency. In this paper, we compare the performance of two RRM schemes for vehicular D2D underlay networks — a CSI-based one and a location-based one, in terms of their required measurement overhead, with implications to general schemes of the respective class.
