LTE Evolution to Build All Business Foundation is a white paper from Huawei that considers how LTE has completely changed the landscape of mobile broadband and everyone’s daily life, brought huge revenues to most mobile operators. However operators are now concerning about how to boost the network capacity and enhance user experience, how to enable new business for new revenue growth, and how to improve the investment efficiency. In recent years, LTE standards and industry are evolving not only to overtake all 2G and 3G services, but also to enable all business as the foundation of the next decade. This white paper presents an overview of how shall we redefine LTE towards the 2020s to address the challenges regarding use experience and network capacity and bring sustainable revenues.
The introduction and increasing use of mobile devices (e.g., smart phones and tablets) and various mobile applications have dramatically changed mobile communications systems and upgraded the cellular technologies from one generation to another. As the dominant 4G technology, LTE, also known as Evolved Universal Terrestrial Access Network (E-UTRAN), was developed by 3GPP starting in 2004 to meet the requirements of diverse mobile applications. LTE is a release-based technology family. In every one to two years, a new release of various key features is specified to meet the requirements of emerging use cases, to support technologies from latest researches, and to address practical issues seen in real deployments.
In the past decade, the LTE family has grown to include LTE, LTE-Advanced, LTE-Advanced Pro and now its further evolution towards satisfying IMT-2020 (a.k.a. 5G) requirements and use cases. On one hand, LTE standards are evolving to ensure ubiquitous evolved mobile broadband (eMBB) experience in terms of latency, coverage, and throughput. On the other hand, LTE standards continue to develop to enable business expansion into vertical markets, e.g., IoT, V2X, unmanned aerial vehicles (UAVs), and industry automation by means of ultra-reliable low-latency communication (URLLC). In addition, LTE is evolving to support the operation of other RATs by means of technologies such as E-UTRAN/NR Dual Connectivity (EN-DC).
