Each issue of the IEEE Journal on Selected Areas in Communications (JSAC) is devoted to a specific technical topic and thus provides to JSAC readers a collection of up-to-date papers on that topic. These issues are valuable to the research community and become valuable references. The technical topics covered by JSAC issues span the entire field of communications and networking. JSAC publishes only papers that are submitted in response to a Call-for-Papers. These calls are published in JSAC issues and other publications of the IEEE Communications Society as appropriate to the subject area of the call. Papers submitted for review for possible publication in a JSAC issue must be submitted to one of the Guest Editors listed in the Call-for-Papers. See "Information for Authors" found in any JSAC issue for additional instructions. Topics for JSAC issues are determined by the JSAC Editorial Board after review of proposals submitted by interested parties. All are invited to submit proposals. Instructions for submitting proposals are included in the Guidelines for Proposal preparation on the JSAC website. Recent issue themes included: Network Coding for Wireless Communication Networks, Wireless and Pervasive Communications for Healthcare, Network Infrastructure Configuration, Broadband Access Networks: Architectures and Protocols, Body Area Networking: Technology and Applications, Underwater Wireless Communication Networks, Game Theory in Communication Systems, Exploiting Limited Feedback in Tomorrow’s Communication Networks.

Special Issue on Wireless Energy Transfer Solutions for Sustainable Connectivity Infrastructure from Space to Ground for 6G
提出日: 2025-10-15

The evolution of 6G will transform global connectivity, supporting applications like global broadband, real-time data sharing, and autonomous systems. These applications will significantly increase energy consumption due to their complexity. Key factors include the need for efficient connectivity across high-mobility platforms (UAVs, HAPS, and space-based systems), advanced communication technologies (massive MIMO, mmWave, THz), and data-intensive applications (AI-driven network management, real-time processing). Additionally, the explosion in device density, from low-power IoT sensors to high-power communication devices, will further drive diverse energy demands, highlighting the critical need for continuous power supply in 6G networks. 

However, current power solutions for these networks face significant limitations. Aerial, space-based, and terrestrial platforms are often constrained by limited onboard energy storage, requiring frequent recharging, refueling, or battery replacements that disrupt continuous operation. Solar energy, while commonly utilized, remains intermittent due to factors such as night cycles, adverse weather conditions, and geographic limitations—especially in high-latitude regions or during extended nighttime periods. Moreover, the dependence on terrestrial infrastructure for refueling or power resupply adds logistical complexity and cost, particularly for platforms operating in remote or high-altitude environments where consistent access to charging stations is limited. Recent advances in high-power wireless power transfer (WPT) technologies, such as laser and RF-based power beaming, offer promising solutions by enabling the wireless delivery of substantial power. These solutions can significantly extend operational duration, enhance platform capabilities, and reduce reliance on traditional energy storage methods. Nevertheless, integrating wireless power transfer (WPT) with communication systems in dynamic 6G networks presents challenges such as interference between energy and data signals, beam alignment, and energy delivery due to high mobility and varying distances. Unlike low-power SWIPT, high-power WPT can disrupt data integrity. Additionally, high-power beams pose safety and security risks, requiring secure transmission protocols and robust safety measures to address these concerns.

This special issue will focus on aspects of the technological, operational, and safety challenges associated with wireless energy transfer in integrated communication systems across global networks for sustainable connectivity.
