The next step in the wireless communications industry vision is 5.5G, which is an enhancement and extension of the 5G scenario to meet the demand for moving from the Internet of Everything to the Smart Connect of Everything, said Xu Wenwei, director of Huawei and president of the Institute for Strategic Studies, recently.
Xu delivered a speech on the theme of "The Future Vision of the Connectivity of Everything" at the recent IEEE GLOBECOM 2020 conference, in which he talked about 5.5G.
He said that 5.5G will first continue to enhance the three standard scenarios of eMBB, mMTC and URLLC defined by ITU.
5.5G will also be expanded to include three new scenarios, including Uplink Centric Broadband Communication, Real-time Broadband Communication, and Harmonized Communication and Sensing, thus turning the "triangle" of 5G scenarios into a richer "hexagon.
According to Xu, 5.5G is derived from 5G and needs to be compatible with all 5G devices.
5.5G needs to achieve flexible use of the entire sub-100GHz band on demand, and needs to be deeply integrated with AI to realize Air Interface+AI, Network+AI, and Service+AI to meet the demands of network diversity and energy management.
5.5G was first proposed at the 2020 Global Mobile Broadband Forum (Global MBB Forum) by Huawei Managing Director and Director of the Product Investment Review Committee Wang Tao, and received great attention at the time.
Wang Tao said the reason why 5.5G was proposed was because of consumers' constant pursuit of the ultimate business experience and the diversity of industrial interconnection scenarios, both of which bring new challenges to 5G connectivity.
