Huawei Pushes 6G with U6GHz Portfolio

The upper 6GHz spectrum (6.425–7.125 GHz) was a key outcome of the ITU's World Radiocommunication Conference in 2023 (WRC-23), identified as a foundational band for the next phase of mobile evolution. This band is critical for delivering the wide channel bandwidths, between 200-400 MHz, considered necessary for 6G. Following WRC-23, nations like China, the UAE, and Brazil are actively moving to identify and allocate this spectrum for mobile use. The push into the U6GHz band is a strategic move within the broader 5G-Advanced framework, defined by 3GPP Release 18 and beyond. 5G-Advanced is designed to enhance network performance and intelligence, supporting more demanding applications like extended reality (XR) and high-precision positioning as a bridge to 6G. The formal study projects for 6G are expected to commence with 3GPP Release 20 in 2025, with the first 6G specifications slated for Release 21. Huawei's portfolio includes Extremely Large Antenna Array (ELAA) technology and intelligent beamforming algorithms to ensure U6GHz coverage is comparable to the C-band. The company has also released new microwave products with full-duplex technology to handle the high-bandwidth backhaul requirements of U6GHz base stations, anticipating a tenfold growth in transport network traffic. Mainstream devices and CPEs supporting the U6GHz band are expected to become commercially available during 2026. The race to patent 6G-enabling technologies is already intense, with over 70,000 related patent applications filed globally. Companies that establish dominant Standard-Essential Patent (SEP) portfolios will significantly influence the future telecommunications market, setting licensing terms and shaping technical standards. This pre-standardization push reflects a global effort to embed proprietary technology into the core fabric of 6G, especially in areas like AI-native networking and resource management. The next pivotal moment for 6G spectrum will be the World Radiocommunication Conference in 2027 (WRC-27), scheduled to be held in Shanghai, China. WRC-27 will consider additional bands for International Mobile Telecommunications (IMT), including frequencies in the 4.4-4.8 GHz, 7.125-8.4 GHz, and 14.8-15.35 GHz ranges. Decisions made at this conference will set the stage for 6G spectrum availability and harmonization for decades to come. This standards-setting process is unfolding amid heightened geopolitical competition, with nations and corporations vying for control over key technologies. The US and EU have released strategies emphasizing a private sector-led approach, while also reserving the right for political intervention to protect national security interests. China has significantly increased its influence in standards bodies like the ITU, viewing technical standard-setting as a crucial element of its state-centric approach to technology leadership.
