Towards a Connected Sky: Performance of Beamforming with Down-tilted Antennas for Ground and UAV User Co-existence
Ramy Amer, Walid Saad, Nicola Marchetti
Providing connectivity to aerial users such as cellular connected unmanned aerial vehicles is a key challenge for future cellular systems. In this paper, the use of conjugate beamf…
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…
Techniques for Cooperative Cognitive Radio Networks
Ramy Amer
The frequency spectrum is an essential resource for wireless communication. Special sections of the spectrum are used for military purposes, governments sell some frequency bands t…
