Non-Orthogonal Multiple Access (NOMA) for cellular future radio access
TL;DR: Considering the trend in 5G, achieving significant gains in capacity and system throughput performance is a high priority requirement in view of the recent exponential increase in the volume of mobile traffic and the proposed system should be able to support enhanced delay-sensitive high-volume services.

NOMA-Assisted Multi-Access Mobile Edge Computing: A Joint Optimization of Computation Offloading and Time Allocation
TL;DR: By exploiting non-orthogonal multiple access (NOMA) for improving the efficiency of multi-access radio transmission, this paper studies the NOMA-enabled multi- access MEC and proposes efficient algorithms to find the optimal offloading solution.
Journal ArticleDOI
Physical Layer Security in Cognitive Radio Inspired NOMA Network
TL;DR: This paper investigates physical layer security in cognitive radio inspired non-orthogonal multiple access (CR-NOMA) networks with multiple primary and secondary users and investigates the performances of secondary users by deriving the closed-form expressions for throughput of secondary network.
Journal ArticleDOI
Joint Energy Efficient Subchannel and Power Optimization for a Downlink NOMA Heterogeneous Network
TL;DR: This paper aims to maximize the entire system energy efficiency, including the macrocell and small cells, in a NOMA HetNet via subchannel allocation and power allocation via convex relaxation and dual-decomposition techniques.
Journal ArticleDOI
Millimeter-Wave Communications With Non-Orthogonal Multiple Access for B5G/6G
TL;DR: This paper studies how beamforming affects the sum-rate performance of mmWave-NOMA, and finds that with conventional single-beam forming, the performance may be offset by the relative angle between NOMA users.

Cooperative diversity in wireless networks: Efficient protocols and outage behavior
TL;DR: Using distributed antennas, this work develops and analyzes low-complexity cooperative diversity protocols that combat fading induced by multipath propagation in wireless networks and develops performance characterizations in terms of outage events and associated outage probabilities, which measure robustness of the transmissions to fading.

TL;DR: The motivation for new mm-wave cellular systems, methodology, and hardware for measurements are presented and a variety of measurement results are offered that show 28 and 38 GHz frequencies can be used when employing steerable directional antennas at base stations and mobile devices.

Massive MIMO for next generation wireless systems
TL;DR: While massive MIMO renders many traditional research problems irrelevant, it uncovers entirely new problems that urgently need attention: the challenge of making many low-cost low-precision components that work effectively together, acquisition and synchronization for newly joined terminals, the exploitation of extra degrees of freedom provided by the excess of service antennas, reducing internal power consumption to achieve total energy efficiency reductions, and finding new deployment scenarios.

Rate control for communication networks: shadow prices, proportional fairness and stability
TL;DR: This paper analyses the stability and fairness of two classes of rate control algorithm for communication networks, which provide natural generalisations to large-scale networks of simple additive increase/multiplicative decrease schemes, and are shown to be stable about a system optimum characterised by a proportional fairness criterion.

Opportunistic beamforming using dumb antennas
TL;DR: This work shows that true beamforming gains can be achieved when there are sufficient users, even though very limited channel feedback is needed, and proposes the use of multiple transmit antennas to induce large and fast channel fluctuations so that multiuser diversity can still be exploited.
