Huawei’s Tau Scaling Law roll-out reaches base stations in blow to US chip curbs

Huawei Technologies is already integrating elements of the Tau Scaling Law – a new chip design principle that helps the company overcome US export controls – into its wireless communications network, as it pushes for broader adoption across its products.

The Chinese tech giant is using the “time compression” concept based on its Tau Scaling Law in its next-generation wireless base stations, according to a company statement released on Wednesday, and the new design is already delivering tangible gains in performance and efficiency.

The firm’s latest UBBPi baseband products, which integrate the time compression concept, deliver a 1.3-fold increase in average network experience, while cutting energy consumption by 40 per cent, the statement said.

The announcement marks the first application of the Tau Scaling Law in Huawei’s base stations – and another milestone in the company’s breakneck roll-out of the new chip design framework.

In May, Huawei first unveiled its Tau Scaling Law and LogicFolding architecture, key semiconductor breakthroughs aiming to deliver transistor performance equivalent to a 1.4-nanometre process node by 2031 without the need for advanced lithography tools that are inaccessible in China.

The Tau Scaling Law, which focuses on time compression and system-level architectural efficiency rather than shrinking physical chip sizes, is viewed as a strategic engineering response to crippling US export controls on advanced chipmaking equipment.

The latest expansion of the principle into Huawei’s communications network comes after the company already rapidly moved to integrate it across its smartphones and computing infrastructure over the past few months.

In September, the company launched the Kirin 9050 Pro, the first commercial chip employing its LogicFolding architecture. Powering Huawei’s new Mate XT 2 trifold smartphone, the Kirin 9050 Pro delivers a 42 per cent leap in overall performance over its predecessor alongside improved power efficiency, according to the company.

The company also planned to deploy the LogicFolding architecture on its flagship Ascend 990 AI chip around 2030, it said.

The launch of Huawei’s latest telecoms products also comes as Beijing lays the groundwork for the early commercialisation of 6G mobile network technology.

In September, China laid out a road map for building a world-leading next-generation telecommunications network by 2030, as part of a five-year plan issued by the Ministry of Industry and Information Technology.

Alongside the UBBPi broadband series, Huawei also launched VitaAAU, which it claimed to be the world’s first commercial Upper 6 GHz equipment. Upper 6 GHz refers to the upper half of the 6 GHz radio frequency spectrum, which serves as a critical bridge for enhancing 5G-Advanced networks and a foundation for future 6G deployment.

The equipment is already seeing commercial deployment in markets such as the United Arab Emirates, supporting peak downlink speeds exceeding 10Gbps, the company said.
