5G高低频组网协同机制与策略
作者:李福昌,王伟
[简介]提出一种综合考虑业务需求、用户体验、终端能力、空口能力、网络状态的协同机制。该机制利用智能化手段预测多层目标网络的用户体验预期,实现用户与网络的最优匹配。该机制按照用户体验最优、网络效能最高的策略编排网络,避免了传统的单一协同机制带来的诸多问题。用户体验与网络效能双优的高低频协同机制与策略对于未来高低频多层网络的有机融合有着重要的理论意义。
面向6G的多频段智能融合组网
作者:谢峰,王菲,刘汉超
[简介]提出了一种新的面向6G 的多频段智能融合模型——Meta-cell 元小区+Stack-free 非栈式用户面。该模型支持高中低任意频段资源的智能编排组合,从而按需实现组网目标,例如在最大化频谱效率和能量效率、减少空口时延和切换时延等目标间取得平衡,从而拥有极高的业务适应能力。Meta-cell 元小区和Stack-free 非栈式用户面通过在组件化、解耦、池化和虚拟化的基础上叠加智能化可编排可配置,解决了现有多频段组网技术不够灵活高效的问题,有助于赋能6G 丰富多样的业务和组网场景。
High-Power Simultaneous Wireless Information and Power Transfer: Injection-Locked Magnetron Technology
YANG Bo, MITANI Tomohiko, SHINOHARA Naoki, ZHANG Huaiqing
[Introduction]Applications using simultaneous wireless information and power transfer (SWIPT) have increased significantly. Wireless communication technology can be combined with the Internet of Things to develop many innovative applications using SWIPT, which is mainly based on wireless energy harvesting from electromagnetic waves used in communications. Wireless power transfer that uses magnetrons has been developed for communication technologies. Injection-locked magnetrons that can be used to facilitate high-power SWIPT for several devices are reviewed in this paper. This new technology is expected to pave the way for promoting the application of SWIPT in a wide range of fields.
Programmable Metasurface for Simultaneously Wireless Information and Power Transfer System
CHANG Mingyang, HAN Jiaqi, MA Xiangjin, XUE Hao, WU Xiaonan, LI Long, CUI Tiejun
[Introduction]Implementing self-sustainable wireless communication systems is urgent and challenging for 5G and 6G technologies. In this paper, we elaborate on a system solution using the programmable metasurface (PMS) for simultaneous wireless information and power transfers (SWIPT), offering an optimized wireless energy management network. Both transmitting and receiving sides of the proposed solution are presented in detail. On the transmitting side, employing the wireless power transfer (WPT) technique, we present versatile power conveying strategies for near-field or far-field targets, single or multiple targets, and equal or unequal power targets. On the receiving side, utilizing the wireless energy harvesting (WEH) technique, we report our work on multi-functional rectifying metasurfaces that collect the wirelessly transmitted energy and the ambient energy. More importantly, a numerical model based on the plane-wave angular spectrum method is investigated to accurately calculate the radiation fields of PMS in the Fresnel and Fraunhofer regions. With this model, the efficiencies of WPT between the transmitter and the receiver are analyzed. Finally, future research directions are discussed, and integrated PMS for wireless information and wireless power is outlined.
