TL;DR: A two-stage joint hovering altitude and power control solution for the resource allocation problem in UAV networks considering the inevitable cross-tier interference from space-air-ground heterogeneous networks is proposed.

TL;DR: A counter-intuitive finding is shown that with a relatively loose maximum transmission power constraint, FD relaying with two-stage self-interference cancellation is preferable to both FD relays with one-stageSelf-Interference cancellation and HD relaying, resulting in a higher optimized EE.

TL;DR: This overview of recent interest in energy-efficient and cost-efficient PHY solutions for securing downlink IoT transmission through interference exploitation discusses the concept of CI, and elaborate the fundamental CI signal design that employs the traditionally undesired interference as a constructive element to LUs while ensuring they are destructive to potential Eves.

TL;DR: A number of promising EE-oriented solutions for designing FD relays enabled systems, including adaptive self-interference cancellation, transmission power adaptation, hybrid relaying mode selection, multi-input-multi-output (MIMO), and massive MIMO FD relaying are outlined.

TL;DR: This work investigates the “signal-to-inference-noise ratio gap reversal” problem of cooperative NOMA systems, which imposes successive interference cancellation (SIC) performance degradation at the SUs, and proposes a low-complexity algorithm for maximizing the system's EE while guaranteeing a successful SIC operation.
