Power Control in Spectrum Sharing Systems with Almost-Zero Inter-System Signaling Overhead
Mohammad Ghadir Khoshkholgh, Halim Yanikomeroglu
Power allocation in spectrum sharing systems is challenging due to excessive interference that the secondary system could impose on the primary system. Therefore, an interference t…
RSS-Based UAV-BS 3-D Mobility Management via Policy Gradient Deep Reinforcement Learning
Mohammad Ghadir Khoshkholgh, Halim Yanikomeroglu
We address the mobility management of an autonomous UAV-mounted base station (UAV-BS) that provides communication services to a cluster of users on the ground while the geographica…
Faded-Experience Trust Region Policy Optimization for Model-Free Power Allocation in Interference Channel
Mohammad G. Khoshkholgh, Halim Yanikomeroglu
Policy gradient reinforcement learning techniques enable an agent to directly learn an optimal action policy through the interactions with the environment. Nevertheless, despite it…
A Vision and Framework for the High Altitude Platform Station (HAPS) Networks of the Future
Gunes Kurt, Mohammad G. Khoshkholgh, Safwan Alfattani +5
A High Altitude Platform Station (HAPS) is a network node that operates in the stratosphere at an of altitude around 20 km and is instrumental for providing communication services.…
Provisioning Energy-Efficiency and QoS for Multi-Carrier CoMP with Limited Feedback
Mohammad G. Khoshkholgh, Victor C. M. Leung, Kang G. Shin +1
We consider resource allocation (RA) in multi-carrier coordinated multi-point (CoMP) systems with limited feedback, in which a cluster of base stations (BSs), each equipped with mu…
Energy-Efficient Cooperative Caching in UAV Networks
Mohammad G. Khoshkholgh, Victor C. M. Leung
For an unmanned aerial vehicle (UAV) enabled network we investigate the energy-efficiency (EE) of joint caching and cooperative communication (Fog-RAN). Since UAVs are battery- and…
Coverage Performance of Aerial-Terrestrial HetNets
M. G. Khoshkholgh, Keivan Navaie, Halim Yanikomerogluy +2
Providing seamless coverage under current cellular network technologies is surmountable only through gross overengineering. Alternatively, as an economically effective solution, th…
Randomized Caching in Cooperative UAV-Enabled Fog-RAN
M. G. Khoshkholgh, Keivan Navaie, Halim Yanikomerogluy +2
We consider an unmanned aerial vehicle enabled (UAV-enabled) fog-radio access network (F-RAN) in which UAVs are considered as flying remote radio heads (RRH) equipped with caching…
How Do Non-Ideal UAV Antennas Affect Air-to-Ground Communications?
M. G. Khoshkholgh, Keivan Navaie, Halim Yanikomeroglu +2
Analysis of the performance of Unmanned Aerial Vehicle (UAV)-enabled communications systems often relies upon idealized antenna characteristic, where the side-lobe gain of UAVs' an…
Caching or No Caching in Dense HetNets?
M. G. Khoshkholgh, Keivan Navaie, Kang G. Shin +2
Caching the content closer to the user equipments (UEs) in heterogenous cellular networks (HetNets) improves user-perceived Quality-of-Service (QoS) while lowering the operators ba…
Delay Analysis of Spatially-Coded MIMO-ZFBF with Retransmissions in Random Networks
Mohammad G. Khoshkholgh, Victor C. M. Leung
For a low-mobile Poisson bipolar network and under line-of-sight/non-line-of-sight (LOS/NLOS) path-loss model, we study repetitive retransmissions (RR) and blocked incremental redu…
