A Survey on Mobile Edge Computing: The Communication Perspective
A comprehensive survey of the state-of-the-art MEC research with a focus on joint radio-and-computational resource management and recent standardization efforts on MEC are introduced. Expand
Energy-Efficient Resource Allocation for Mobile-Edge Computation Offloading
This paper studies resource allocation for a multiuser MECO system based on time-division multiple access (TDMA) and orthogonal frequency-divisionmultiple access (OFDMA), for which the optimal resource allocation is formulated as a mixed-integer problem. Expand

A new network architecture that overlays an uplink cellular network with randomly deployed PBs for powering mobiles, called a hybrid network, is proposed and it is proved that the outage constraint is satisfied so long as the product pλ<sub>b</sub><sup>α/2</sup> is above a given threshold where α is the path-loss exponent.

Performance of Orthogonal Beamforming for SDMA With Limited Feedback
Numerical results show that PU2RC achieves higher throughput and is more robust against CSI quantization errors than the popular alternative of zero-forcing beamforming if the number of users is sufficiently large, and the asymptotic throughput scaling laws forPU2RC with a large user pool are derived for different regimes of the signal-to-noise ratio (SNR).

Opportunistic Wireless Energy Harvesting in Cognitive Radio Networks
A stochastic-geometry model in which PTs and STs are distributed as independent homogeneous Poisson point processes (HPPPs) and communicate with their intended receivers at fixed distances is considered, which reveals key insights to the optimal network design. Expand
Energy Efficient Mobile Cloud Computing Powered by Wireless Energy Transfer
A novel solution that seamlessly integrates two technologies, mobile cloud computing and microwave power transfer, to enable computation in passive low-complexity devices such as sensors and wearable computing devices is presented. Expand
Broadband Analog Aggregation for Low-Latency Federated Edge Learning
This work designs a low-latency multi-access scheme for edge learning based on a popular privacy-preserving framework, federated edge learning (FEEL), and derives two tradeoffs between communication-and-learning metrics, which are useful for network planning and optimization. Expand
Simultaneous Information and Power Transfer for Broadband Wireless Systems
A novel approach is presented in this paper for realizing SWIPT in a broadband system where orthogonal frequency division multiplexing and transmit beamforming are deployed to create a set of parallel sub-channels forSWIPT, which simplifies resource allocation. Expand
Energy Harvesting Wireless Communications: A Review of Recent Advances
The current state of the art for wireless networks composed of energy harvesting nodes, starting from the information-theoretic performance limits to transmission scheduling policies and resource allocation, medium access, and networking issues are provided. Expand
Spectrum sharing between cellular and mobile ad hoc networks: transmission-capacity trade-off
The transmission capacities of the coexisting networks are proved to satisfy a linear equation, whose coefficients depend on the spectrum sharing method and whether SIC is applied, and which shows that spectrum overlay is more efficient than spectrum underlay. Expand
