A Framework for Optimizing Multi-cell NOMA: Delivering Demand with Less Resource
Lei You, Lei Lei, Di Yuan +3
Non-orthogonal multiple access (NOMA) allows multiple users to simultaneously access the same time-frequency resource by using superposition coding and successive interference canc…
Wireless Network-Level Partial Relay Cooperation: A Stable Throughput Analysis
Nikolaos Pappas, Jeongho Jeon, Di Yuan +2
In this work, we study the benefit of partial relay cooperation. We consider a two-node system consisting of one source and one relay node transmitting information to a common dest…
User-centric Performance Optimization with Remote Radio Head Cooperation in C-RAN
Lei You, Di Yuan
In a cloud radio access network (C-RAN), distributed remote radio heads (RRHs) are coordinated by baseband units (BBUs) in the cloud. The centralization of signal processing provid…
Resource Optimization with Load Coupling in Multi-cell NOMA
Lei You, Di Yuan, Lei Lei +3
Optimizing non-orthogonal multiple access (NOMA) in multi-cell scenarios is much more challenging than the single-cell case because inter-cell interference must be considered. Most…
Cost-optimal caching for D2D networks with user mobility: Modeling, analysis, and computational approaches
Tao Deng, Ghafour Ahani, Pingzhi Fan +1
Caching popular files at user equipments (UEs) provides an effective way to alleviate the burden of the backhaul networks. Generally, popularity-based caching is not a system-wide…
Beam Based Stochastic Model of the Coverage Probability in 5G Millimeter Wave Systems
Cristian Tatino, Ilaria Malanchini, Danish Aziz +1
Communications using frequency bands in the millimeter-wave range can play a key role in future generations of mobile networks. By allowing large bandwidth allocations, high carrie…
An Examination of the Benefits of Scalable TTI for Heterogeneous Traffic Management in 5G Networks
Emmanouil Fountoulakis, Nikolaos Pappas, Qi Liao +2
The rapid growth in the number and variety of connected devices requires 5G wireless systems to cope with a very heterogeneous traffic mix. As a consequence, the use of a fixed TTI…
