Huawei iHashBAND 5G solution promotes innovative, intelligent multi-band convergence | Wbactive

5G is happening and fast! More than 200 CSPs have so far deployed 3GPP-compliant 5G networks worldwide, with 5G subscriptions set to surpass the billion mark in the coming months. CSPs will double in 2022 and 2023 to deploy next-generation 5G NR network architecture. They look forward to reaping the benefits of an advanced and intelligent network infrastructure that can unlock newer capabilities and services, as well as monetization opportunities not previously possible. These capabilities result from a combination of advanced RAN equipment and intelligent software that can efficiently utilize diverse spectrum and other network resources.

However, we believe 5G is a spectrum game and the success of a CSP’s 5G network is in the how efficiently it uses the multiple frequency bands in a single network for different use cases, usage scenarios and fulfilling the 5G promise of larger capacity, higher throughput and lower latency. For example, considering the diverse spectrum available for a 5G network, the sub-3 GHz FDD frequency bands offer a symmetrical uplink (UL) and downlink (DL) with broader coverage, while the TDD frequency bands (like C -Band 3.5GHz) offer larger bandwidth and higher capacity. Both can be augmented with higher-order mmWave spectra (26 GHz and above) for high throughput and bandwidth but targeted hotspot coverage for applications such as FWA and private networks.

This increases network complexity many-fold as a CSP attempts to leverage a wide range of spectrum resources across a heterogeneous network to enable a variety of services, SLAs, and target network KPIs.

Each CSP strives to build such a robust, high-performing 5G network with its ecosystem partners. However, having followed the infrastructure market for years, one solution that stands out and is being successfully deployed to bring intelligence to this converged multi-band RAN is Huawei’s iHashBAND solution.

At Huawei Forum Mobile Broadband 2022 (MBBF), which was recently held in Bangkok and was also attended by a team of Counterpoint analysts, the global leader in mobile network infrastructure provided briefings on its latest innovations, solutions and adoption by CSPs in 5G infrastructure around the world. Huawei presented its iHashBAND solution at the summit, which was one of the highlights of the show. This solution looks ideal Converge the multiple frequency bands (5G and 4G) in a single-layer network Solving one of the biggest pain points for CSPs migrating from 4G to 5G. This allows the CSPs to take full advantage of the performance differences TDD and FDD spectrum bands to reinforce the respective band thicknesses with regard to capacity versus coverin order to Increase in spectral efficiency. A… have Single logical band approach With the convergence of multiple spectrum bands being deployed on a single network, CSPs moving towards it can reap significant benefits “A 5G” implementation.

Huawei further enhances this by adding multiple 3GPP-compliant features, advanced software techniques, and proprietary intelligent algorithms to make the most of this multi-band convergence. For example, the solution includes the following features:

Flexible full-band uplink-downlink decoupling

While 4G was more about content consumption, downloading and easy uploading, in the 5G era Decoupling of uplink (L) and downlink (DL) becomes a groundbreaking feature. This enables operators to improve TDD UL and DL coverage, throughput at the cell edge, and more Flexible multiplexing in the time and frequency domain from several tapes over Super Uplink (SUL). SUL allows FDD uplink spectra to complement TDD bands, allowing coordination of TDD and FDD spectra and increasing UL coverage.

SUL is an innovative capability that enables 100MHz SUL bandwidth to increase UL performance and throughputs (to over 1Gbps) by at least 5x. As a result, Huawei’s SUL helps CSPs Boost overall UL user experience by 30%. SUL enables UL critical applications such as 4K live video transmissions, HD video conferencing, image processing systems and cloud gaming, which was not possible on a 4G network at this scale and efficiency. Working with ecosystem players, Huawei will ensure that most 5G devices and CSPs support this feature. 5G NR devices with HiSilicon, MediaTek and UNISOC chipsets already support the SUL function.

Full band multi-beam 3D coordinated scheduling

Traffic planning through efficient use spatial multiplexing is a key technology for driving performance. However, coordinated scheduling Using multiple antenna technology across multiple bands and optimally distributing the data load across multiple beams goes a few steps further.

This intelligent Optimizing UE pairing across multiple bands and beams can significantly 20%+ increase in spectral efficiency and cell capacity. This is ideal for CSPs looking to increase capacity through intelligent traffic balancing, especially for 5G FWA applications such as 4K/8K videocloud gaming and VR streamingwhich requires more bandwidth.

Intelligent grid-based coordination for intermediate frequency measurement

Furthermore, in a traditional coordination process, the intermediate frequency Measurement on a multi-band network can take seconds, resulting in significant performance loss. As a result, base station intelligence functions within the IHashBAND solution such as “intelligent prediction” of multiband properties by a Grid-based coordination techniquecan reduce these intermediate frequency measurements to less than 200 ms. This unlocks several advanced use cases, e.g fast carrier aggregation (CA)intelligent anchor selection, intelligent carrier selection, and intelligent NSA EN-DC carrier combination selection. This in turn promises thrust the total Network performance by 20-30% without the need for additional spectrum or other hardware resources.

Since the success of 5G networks will depend on how CSPs can build a highly efficient and optimized multi-band single network, solutions like Huawei’s IHashBAND offer a great option to achieve the same. Huawei’s IHashBAND enables the convergence of multiple bands from legacy 4G FDD with 5G NR TDD spectrum into a single logical band supported by some intelligence and software techniques. This is beneficial for both on-premises and cross-premises intelligent aggregation, increasing coverage and enabling better throughput experience as well as efficient carrier aggregation to intelligently achieve a consistent experience.

Therefore, it is imperative to move to a 5G “smart” base station that performs very well with greater spectral efficiency, capacity increases and improved user experience.
