The recent publications in the field of wireless communication and coded caching demonstrate a significant push towards optimizing network efficiency and performance through innovative strategies and technologies. A notable trend is the exploration of movable antenna (MA) systems to enhance energy efficiency (EE) in multiple-input multiple-output (MIMO) communications, leveraging statistical channel state information for optimization. Additionally, there's a growing interest in device-to-device (D2D) coded caching within multiaccess networks, aiming to improve load per user and subpacketization levels through novel combinatorial access topologies. The integration of coded caching into MIMO communications is also being advanced, with strategies designed to maximize degrees of freedom (DoF) in asymmetric configurations. Furthermore, efforts to simplify multi-antenna coded caching systems by eliminating the need for successive interference cancellation (SIC) are evident, alongside the development of hierarchical coded caching schemes that outperform existing solutions in high memory regimes. The field is also seeing progress in the construction of placement delivery arrays (PDAs) for coded caching, aiming for exponential growth in user numbers and caching gain. Lastly, the application of fluid antenna multiple access (FAMA) in wireless powered communication networks (WPCNs) is being explored to enhance data and energy transfer services.
