Hücresel kullanıcı ile eşzamanlı kanal paylaşan cihaz-cihaz haberleşmesi için kanal paylaşımı ve zamanlaması

Öz

Cihaz-Cihaz (CCH) haberleşmesi, gelecekteki 5G ağları için gelecek vaat eden teknolojilerden biridir. Hücresel şebekelerde CCH'nin kullanılması kapasite ve gecikme bakımından kazanç sağlamıştır. Bununla birlikte, CCH’nin hücresel kullanıcı ile ortak kanalı kullandığı durumda ana endişe, CCH kullanıcısı ve hücresel kullanıcı arasındaki karşılıklı girişimden dolayı hücresel kullanıcı için hizmet kalitesidir. Hücresel kullanıcının hizmet kalitesini (QoS) ihlal etmeden D2D haberleşmenin sağladığı kazançtan faydalanmak için kaynak paylaşımı önemli bir tasarım kriteridir. Bu çalışmada, Cihaz-Cihaz haberleşmesinin hücresel kullanıcının yukarı yönlü bağlantısını ortak kullandığı bir senaryoda kaynak paylaşım sorununu incelemek amacıyla bir optimizasyon modeli sunuyoruz. Önerilen modeli, birden çok CCH çiftinin bir hücresel kullanıcının yukarı bağlantı kaynağını paylaştığı örnek bir kaynak paylaşım senaryosu için kullanarak farklı parametre ayarları için gecikme ve toplam veri hızını inceliyoruz. Sonuç olarak, az sayıda D2D çiftinin hücresel kaynakları yeniden kullanmasının toplam veri hızı açısından önemli olduğunu gözlemledik.

Resource sharing and scheduling in device-to-device communication underlying cellular network

Abstract

Device-to-Device (D2D) communication is one of the promising technology for the future 5G networks. Utilizing D2D in cellular networks has advantage in terms of capacity and delay. However, in D2D underlay cellular setting, the main concern is quality of service (QoS) for the cellular user due to the mutual interference between D2D user and the cellular user (CU). To utilize the gain brought by D2D setting without violating QoS of the CU, resource sharing is an important design criteria. To this end, we present an optimization model to investigate a resource sharing problem combined with scheduling in a D2D uplink underlay setting. We have used the proposed model to investigate an example resource sharing scenario, in which multiple D2D pairs share the uplink resource of CU, and identified delay and sum throughput for different parameter settings. We observed that there is a significant gain in terms of sum-throughput in allowing a small number of D2D pairs to re-use the cellular resources.
