摘要:

大规模机器类通信(mMTC,massive machine-type communication)被列为5G网络的三大应用场景之一,但真正成熟的万物互联需要到未来6G网络才能实现。6G物联网将同时提供高速率、低时延、高可靠、大连接等全方位服务,实现深度沉浸式泛在连接。首先,展望了 6G 技术和 6G 物联网的技术挑战,总结了现有物联网的物理层传输技术。然后,重点介绍和讨论了一类新型的面向 6G 物联网的主被动互惠传输技术,为 6G 物联网传输提供一种新的解决方案和实现途径。最后,讨论了在6G物联网主被动互惠传输方面具有重要意义的研究方向。

Abstract:

mMTC (massive machine-type communication) is one of the three major application scenarios of 5G network,but it is highly likely that the truly mature Internet of everything may not be realized until the future 6G network.In order to realize the deep immersive ubiquitous connection network,6G IoT will simultaneously provide all-round services such as high data rate,low latency,high reliability and massive connections.Firstly,the 6G was prospected and the technical challenges of 6G IoT were summarized.Then the existing physical layer transmission technologies of IoT were reviewed.Next,the promising symbiotic transmission technologies for 6G IoT were introduced and discussed,which enable the possibility that active transmission and passive transmission facilitates each other and provide a new solution for 6G IoT transmission.Finally,some possible future research directions were presented for symbiotic transmission in 6G IoT.

Key words: 6G, Internet of things, ambient backscatter technology, intelligent reflecting surface communication
