At the Global Mobile Broadband Forum 2018, Huawei released the industry-leading LTE 4T6S 2.0. The solution uses four innovative technologies, including next-generation ultra-wideband multi-beam antennas, high-power dual-band 4T4R RRUs, performance optimization algorithms for overlapping areas, and an intelligent planning tool. With 4T6S 2.0, network capacity is enhanced on multiple frequency bands. The introduction of performance optimization algorithms improves user experience in overlapping areas by more than 10% while the overall site planning efficiency is also greatly increased. In addition, this solution has the added advantage of supporting FDD and TDD co-site and co-antenna deployment, playing a large part in building effective and simple sites.

The next-generation multi-beam antenna has better performance and allows for more product models

The solution uses Huawei patented cutting-edge antenna array technology, further suppressing inter-beam interference. An adaptive feedback system enables optimal multi-band performance on 1.8–2.6 GHz. A revolutionary series of antenna products are provided to integrate low-frequency ports and simplify sites, meeting deployment requirements across diverse scenarios.

Industry-leading high-power dual-band 4T4R RRUs

With its newly introduced contemporary design, the efficiency and capability of RRU power amplifiers are greatly increased. Using high-power dual-band 4T4R RRUs, 4T6S 2.0 can be deployed on both 1.8 GHz and 2.1 GHz frequency bands, improving network coverage and user experience. With the wideband integrated power amplifier technology, software configuration can be used to enable power sharing between different bands and RATs. Efficient power utilization can further improve user experience at the cell edge by 5% to 20%.

Feature optimization algorithms improve user experience in overlapping beam areas

When multiple sectors are used, beams will overlap. Huawei uses innovative features such as inter-sector joint scheduling optimization and multi-band coordinated scheduling optimization for base stations to select the most suitable time-frequency resource allocation mode. This enhances the performance in overlapping areas and improves user experience by 10%. The coordinated scheduling optimization algorithms allow 4T6S sites to achieve maximum levels of performance.

The intelligent planning tool supports quick site selection and provides beam optimization advice

The 4T6S solution provides the highest capacity gains when traffic is evenly distributed among sectors. In order to ensure a more intelligent and efficient optimization of sector azimuths and traffic distribution, Huawei develops an intelligent planning tool. The tool supports a quick batch selection of sites that are suitable for deploying 4T6S. It also provides azimuth optimization advice using intelligent algorithms to achieve the best performance. These combined efforts help to significantly increase overall site planning efficiency.

Chen Chuanfei, President of Huawei LTE FDD Product Line, said, "4T6S is one of the most important innovative technologies for LTE capacity evolution. It can help improve network capacity and enable 4x4 MIMO to provide high user experienced data rates. 4T6S 2.0 has achieved a series of industry-leading technological breakthroughs in key fields, enabling better performance, more applicable scenarios, and easier deployment. Through a series of innovative solutions, it is our sincere hope that we can help operators build high-quality networks with superior capacity and user experience, maximize spectrum value, and promote continuous development."
