Abstract:
Six-dimensional movable antenna (6DMA) has been recently recognized as a promising technology for enhancing wireless network performance through adjusting antenna's position and/or orientation at the transceiver. In this talk, we provide a comprehensive overview of MA with flexible antenna positioning, including its historical development, practical architectures and implementation methods, contemporary applications in wireless networks, as well as mathematical models, design issues and promising approaches to solve them. Various performance advantages of MA over conventional fixed-position antenna is demonstrated, in terms of spatial diversity/multiplexing, interference mitigation, flexible beamforming, as well as wireless sensing. In particular, a general 6DMA framework is introduced, which includes existing antenna/array positioning (with fixed orientation) or rotation (with fixed position) models as special cases. Finally, we shed light on research directions worthy of investigation in future work to unleash the full potential of MA/6DMA for wireless networks. Biography:
