Cooperative Transmission and Probabilistic Caching for Clustered D2D Networks
Ramy Amer, Hesham ElSawy, Jacek Kibiłda +2
In this paper, we aim at maximizing the cache offloading gain for a clustered \ac{D2D} caching network by exploiting probabilistic caching and cooperative transmission among the cl…
Caching to the Sky: Performance Analysis of Cache-Assisted CoMP for Cellular-Connected UAVs
Ramy Amer, Walid Saad, Hesham ElSawy +2
Providing connectivity to aerial users, such as cellular-connected unmanned aerial vehicles (UAVs) or flying taxis, is a key challenge for tomorrow's cellular systems. In this pape…
Optimizing Joint Probabilistic Caching and Communication for Clustered D2D Networks
Ramy Amer, Hesham Elsawy, M. Majid Butt +3
Caching at mobile devices and leveraging device-to-device (D2D) communication are two promising approaches to support massive content delivery over wireless networks. The analysis…
5G Massive MIMO Architectures: Self-Backhauled Small Cells versus Direct Access
Andrea Bonfante, Lorenzo Galati Giordano, David López-Pérez +5
In this paper, we focus on one of the key technologies for the fifth-generation wireless communication networks, massive multiple-input-multiple-output (mMIMO), by investigating tw…
On Minimizing Energy Consumption for D2D Clustered Caching Networks
Ramy Amer, M. Majid Butt, Hesham ElSawy +3
We formulate and solve the energy minimization problem for a clustered device-to-device (D2D) network with cache-enabled mobile devices. Devices are distributed according to a Pois…
Spectrum Matching in Licensed Spectrum Sharing
M. Majid Butt, Irene Macaluso, Eduard A. Jorswieck +3
Spectrum sharing is one of the promising solutions to meet the spectrum demand in 5G networks that results from the emerging services like machine to machine and vehicle to infrast…
