At Win-Win·Huawei Innovation Week, Yang Chaobin, President of Huawei’s Wireless Solution, delivered a keynote address entitled “Continuous Innovation Towards 5.5G for a New Journey of 5G Industry”. In his speech, Yang summarized the key features of 5.5G – 10Gbps experience, 100 billion connections and native intelligence. “Powered by new toC and toB services, we will improve eMBB, URLLC and mMTC and provide new capabilities for sensing, passive IoT, positioning and native intelligence. With them, we will build intelligent 5.5G supporting 10Gbps downlink, 1Gbps uplink and 100 billion connections, and embark on a new journey of 5G.”

5G improvements are essential to support new user experiences and digital industry services. As XR Pro and other TOC services grow in popularity, networks need to increase user-perceived mobile connection rates tenfold. ToB services require high uplink speeds and detection capabilities, medium-speed connections, and passive IoT. “This means that 5.5G networks will offer 10Gbps downlink speed and 1Gbps uplink speed, support 100 billion IoT connections, and need to become intelligent by nature,” Yang commented.
Ultra-high bandwidth and ELAA are key to the 10 Gbps downlink. Ultra-wide bandwidths have proven to be essential for mobile networks, as all sub-100 GHz resources must be fully utilized. As increasingly high bands are used, an extremely large antenna array (ELAA) will be required to address the resulting coverage contraction. ELAA enables high-band networks to provide the same coverage as C-band, allowing operators to deliver 10 Gbps to all users anytime, anywhere. ELAA MetaAAUs have been commercially deployed in more than 30 cities. Field tests are conducted in the 6 GHz band and show that joint coverage with the C band is possible in cases where field deployments cover outdoor (O2O) and indoor (O2I) users. mmWave can ensure a total peak rate of 10 Gbps, with a Gbps experience possible even at a distance of 5 km.
Improved uplink/downlink decoupling and multi-band convergence are key to 1Gbps uplink. ToB connections often have far stronger uplink capabilities than downlink. Since the uplink is decoupled from the downlink, toB services flexibly use uplink and downlink spectrum on different bands, including the existing FDD spectrum and the newly defined uplink-only spectrum. Spectrum convergence will be possible through uplink/downlink decoupling to ensure Gbps uplink. So far, uplink/downlink decoupling has been used commercially in the mining and steel sectors to ensure the 1Gbps uplink transmission required for 100-channel HD backhaul and panoramic remote control.
5G-based RedCap, NB-IoT and passive IoT will enable 100 billion connections in the next 10 years. RedCap is already available for commercial use. Compared to eMBB, RedCap features low power consumption and high cost efficiency, which makes it easy to scale up. Passive IoT combines cellular and passive tagging and features low device prices and long ranges, providing an ideal option for connecting tens of billions of passive IoT devices. Based on Huawei’s verification, passive IoT supports a range of more than 200m. In addition, the sensors will be integrated with cellular networks, which facilitates the use of high-bandwidth mmWave to improve sensor precision. Therefore, speed and distance measurements and imaging will be enhanced to further improve exception identification for smart transportation, geo-fencing for smart factories and other industrial applications, ultimately enabling digital replication.
5.5G will ensure native intelligence for service operations, network optimization and simplified O&M. 5G developments will increase service diversity and differentiation as multi-band networks and radio access technologies operate simultaneously. This justifies the urgent need to introduce intelligence into cellular networks to maximize resource utilization and ensure service experiences. In addition, the intelligence will best balance network performance and energy consumption, which will be important to meet the increasing demand for 5G traffic. Native intelligence will further enable networks to facilitate real-time collection, modeling and prediction, and multi-dimensional decision making. In this way, networks are intelligently optimized, with the ability to configure different resources as needed to provide optimal user experience and capacity. Operations and maintenance are intelligently simplified, automating site planning, deployment, and troubleshooting to maximize performance and energy savings.
“To meet the diverse needs of the next 10 years in different industries, 5G must enhance existing capabilities and support new capabilities of high-precision sensing, passive IoT, and native intelligence. We will continue to work with global partners to further innovate 5G and strive for the 5.5G era by protecting operators’ investments,” Yang concluded.
