“…None of the above frameworks consider any of the standard 5G technologies, except for [1] and [6], which at best implement network densification. Nevertheless, some recent works have integrated caching with either FR2 [7]- [9] or massive MIMO [10]- [12] communication, though no work till date has integrated both technologies with caching in a hybrid network framework.…”

To alleviate the backhaul congestion in future hybrid heterogenous networks, this paper investigates the potential benefits of implementing storages in small base stations (SBSs) operating at frequency range 2 (FR2) bands that co-exist with a tier of massive multiple input multiple output (MIMO) macro BSs (MBSs) operating at frequency range 1 (FR1) bands. We develop a unified analytical framework and derive theoretical bounds for such a cache-enabled FR1-FR2 hybrid network under limited backhaul scenario to analyze the exact and approximate latency, average success probability of file delivery, and average data rate considering two open-access user association policies: i) location-based and ii) content-based association. Numerical results demonstrate that wireless edge caching (WEC) can improve the performance of hybrid wireless networks, albeit certain tradeoffs, e.g., increasing cache-enabled SBSs cannot always improve the network performance and there exists an optimal SBS density that provides the best latency and throughput performance. Furthermore, we compare the performance of the network with respect to other key network design parameters such as cache size, content popularity, backhaul capacity, and blockages for both the user associations. Our results show that latency under content-based user association is less than that of location-based user association, and although the difference in the average rates under the two user associations is not obvious, content-based association can extricate more backhaul capacity and thus reduce installation cost significantly. Index Terms-Wireless edge caching, FR1, FR2, massive MIMO, stochastic geometry, hybrid HetNets. 1 Early 5G deployment will ensure that FR2 SBSs co-exist with FR1 macro BSs to provide seamless connectivity.

“…Such system becomes an easy and cost-efficient deployment solution. Some other advanced technologies, such as full duplex (FD), caching and massive multiple-input and multiple-out (MIMO), are introduced to facilitate dense deployment of small cell base stations (SBSs) [27]. A small-cell network was studied in the context of Hetnet-based cellular networks for both downlink and uplink by introducing three techniques including full-duplex transmission mode, energy harvesting, and power domainbased NOMA schemes [28].…”

Satellite communication systems need to be integrated with emerging small-cell network to provide seamless connectivity and high-speed broadband access for mobile users in future wireless networks. In this paper, we study a hybrid satellite-terrestrial relay system (HSTRS) employing small cell transmission under interference constraint with macro-cell users. To characterize such HSTRS-assisted small-cell network, Shadowed-Rician fading for satellite links and Nakagami-m fading for terrestrial links are adopted. We further deploy non-orthogonal multiple access (NOMA) to improve spectrum efficiency. To provide performance analysis, we derive exact formulas for outage probability and throughput of the considered HSTRS, and further examine its achievable diversity order. More importantly, we conduct the performance analysis by indicating performance gaps among two users, and such a gap depends on power allocation factors. We evaluate key performance metrics through the derived analytical expressions to provide useful framework of HSTRN and to characterize the impact of interference in different cells, and integer values of the per-hop fading severity parameters. The useful guidelines are introduced in the design of futuristic HSTRS for small-cell communications.

“…This considerable benefit has not been widely recognized. Besides, recent works have indicated the feasibility of employing FD techniques to improve the offloading throughput by cooperatively receiving data from several CPs [11], [12] or from the macro base station (MBS) [13], while simultaneously transmitting data to the requester. In [12], FD transmission is included when simultaneous requests occur inside a D2D pair.…”

Cooperative Full Duplex Content Sensing and Delivery Improves the Offloading Probability of D2D Caching

A novel policy is conceived for device-to-device (D2D) caching that facilitates content sensing and delivery using full-duplex (FD) communications. As a benefit, the user devices become capable of performing content sensing and delivery over an extended geographic range, where more aggregate cache units are available, hence circumventing both the limited communication range and the limited storage of individual devices. Based on stochastic geometry-aided modeling of the network, we analytically derive the hit ratio, defined as the probability that a content requester can obtain desired file via a D2D link or an FD D2D link with data rate larger than a given threshold. The accuracy of our analysis is validated by our Monte Carlo simulations. Our numerical results show that the proposed policy achieves higher offloading probability than that of the existing approaches, even in the face of limited self-interference cancellation capability. INDEX TERMS Full duplex, stochastic geometry, D2D caching.
