Summary: The article proposes two SWIPT cooperative spectrum sharing methods to improve the energy and spectrum efficiency for 6G-enabled cognitive IoT network. IoDs access the primary spectrum by serving as OFDM relay with the energy harvested from the received RF signal. The achievable rates of the cognitive IoT system with AF and DF relaying mode are maximized through joint power and subcarrier optimization, while ensuring the target rate of the primary system, demonstrating improvement in spectrum and energy efficiency through simulation results.

Summary: This article proposes an efficient polar coded selective decode-and-forward (SDF) cooperation method to address the error propagation issue in satellite IoT devices with terrain shielding. The method utilizes channel state information (CSI) to derive a new decision threshold based on the channel gain ratio of the optimal relay-destination link (R-D). Simulation results show that the proposed scheme achieves about 0.9 dB and 0.5 dB gains at a bit error rate (BER) of 10-4, respectively, compared to non-cooperation and existing polar coded cooperation channels.

Summary: This paper investigates a simultaneous wireless information and power transfer (SWIPT)-assisted cognitive overlay-based MIMO downlink cooperative relaying system, where a secondary network consisting of an energy harvesting base station and wireless-powered secondary users shares the spectrum of a primary network. Closed-form expressions for the end-to-end outage probability are derived considering Rayleigh fading channel links, sensitivity and saturation impairments at the energy harvesting nodes. The impact of energy harvesting impairments and finite battery on the system performance are also analyzed.

Summary: This paper investigates the performance of cooperative cognitive radio networks based on simultaneous wireless information and power transfer, deriving the outage probability in closed-form expressions. Increasing transmit power and/or the number of relays is beneficial for reducing the outage probability. Monte Carlo simulations are used to validate the mathematical analysis and show the behavior of outage probability with respect to key parameters.

Summary: In this article, a state-of-the-art downlink communication transceiver design is proposed for transmissive reconfigurable metasurface (RMS)-enabled simultaneous wireless information and power transfer (SWIPT) networks. The design includes a feed antenna for beamforming and builds spatial propagation models for plane and spherical waves. A robust system sum-rate maximization problem is formulated considering imperfect channel state information (CSI), and the nonconvex optimization problem is solved using an alternating optimization (AO) framework with successive convex approximation (SCA), penalty function method, and difference-of-convex (DC) programming. Numerical results show the proposed algorithm has convergence and outperforms other benchmark algorithms.
