Due to recent advances in Radio Frequency (RF) energy harvesting circuits over the past decade, the investigation of far-field wireless power transfer techniques in energy-constrained wireless networks such as dense outdoor cellular networks, indoor wireless networks, wireless sensor networks, and Internet of Things (IoT) applications has received significant attention. As the RF signals can carry two important entities, i.e., energy and information, the wireless energy signal can be sent over the air with the sole objective of providing energy or with the possibility of being combined with the information signal. In the latter approach, RF energy harvesting and information decoding can be theoretically performed from the same RF signal input, resulting in the concept of Simultaneous Wireless Information and Power Transfer (SWIPT). However, the two objectives of maximizing the information rate and maximizing the energy transfer compete with each other and a clear trade-off occurs between information decoding and energy harvesting, which has been analysed for SWIPT systems in the literature in various system settings. One of the promising ways of enhancing the RF energy transfer efficiency of the traditional single antenna-based systems is to exploit suitable multi-antenna techniques such as joint energy and information beamforming, antenna selection, and space division multiple access. In this direction, there have been significnat research activities over the last decade. However, several challenges need to be addressed in order to fully incorporate SWIPT in emerging fifth generation (5G) and beyond wireless networks.
This Special Issue focuses on recent advances in the areas of RF energy harvesting, Wireless Power Transfer (WPT) and SWIPT technologies for the 5G and beyond wireless networks. In this direction, we invite researchers from academia, industry, and governmental organizations to submit their novel works on theoretical models, hardware prototype results, and standardization activities in the related areas.
The main topics of interest for this Special Issue include, but are not limited to, the following:
- Receiver architectures for energy harvesting and SWIPT systems
- SWIPT techniques for multiantenna and multicarrier wireless systems
- Algorithms and protocols for SWIPT/RF wireless power transfer in emerging 5G wireless networks such as massive MIMO systems, cooperative relay networks, small cells, full duplex and mmWave systems
- Resource allocation/management and interference mitigation in SWIPT/RF wireless power transfer enabled heterogeneous wireless systems
- Energy beamforming/precoding and low-complexity antenna partition techniques for SWIPT in multi-antenna wireless systems
- Energy harvesting in IoT/M2M/V2V/D2D environments such as wireless body area networks, smart homes, connected vehicles, smart cities and smart industry
- Hardware prototype design for wireless power transfer/energy harvesting
- Standardization activities for RF energy harvesting/SWIPT
- SWIPT/RF wireless power transfer assisted hardware impairment in wireless networks
