Zero wait means that mainstream services, such as HD video and web browsing, can be accessed without any perceivable delay, providing 5G-like user experience. Zero wait time ensures optimal LTE user experience and makes new services (such as VR and cloud gaming) possible. In addition, user experience will not deteriorate after 5G users leave the coverage area and fall back to the LTE network. To realize zero wait time, the LTE network capacity needs to be further improved to avoid user experience deterioration caused by network congestion. The target data rate for experience-based LTE networks should be increased to 50 Mbps to narrow the gap with the 5G NR, which aims to provide 100 Mbps. "Zero fallback with 50 Mbps" will become the standard for constructing experience-based LTE networks in the next phase.
Through technology evolution and industry promotion, Huawei aims to enable users to enjoy 50 Mbit/s LTE experience with zero wait time anytime, anywhere, monetizing network capabilities.
Huawei plans to foster future services based on the capabilities to offer 5G-like high rates and low latency in order to prepare for the impending 5G era.
LTE will be evolving to multi-band networks. How to maximize spectrum utilization on a complicated multi-band network will be a significant challenge. Huawei has launched the SuperBAND solution to meet this challenge. This solution maximizes spectral efficiency through seamless intra-band bandwidth, inter-band coordination, and intelligent O&M.
Phase 2 (1–10 ms one-way latency over the air interface in 99% of areas): Fast uplink access (1 ms semi-persistent scheduling, chip ready in Q3 2018) and Short TTI (chip ready in Q2–Q3 2020) in eRAN15.1 are the main technologies used. Short TTI allows for scheduling at intervals of two to three OFDM symbols, reducing the one-way latency over the air interface from 10 ms to 1 ms, which is close to the one-way latency target of 0.5 ms over the 5G NR air interface.
All bands to LTE，multi-sector and multi-antenna enable LTE capacity evolution, helping operators resolve capacity bottlenecks.
This first isSeamless large horizontal band: Spectrum resources are scarce and expensive. Huawei uses 5G large-bandwidth filtering technology to exploit LTE guard band spectrum.
Plug-and-play: The built-in AISU automatically collects information such as downtilt angle, azimuth, height, and longitude and latitude to reduce site installation errors, improve site installation efficiency, and reduce secondary site visit costs.
