Abstract 1 (Day 1, Workshop 1/Session 1)
Experiences from 5G Access Trials in Japan
The development of the “5G” mobile system is pushed forward all over the world for a service launch of about 2020 as a target. 5G will be used for more diverse purposes. One of the goals is “Enhanced mobile broadband” providing several Gbps throughput, which is about 10-100 times faster than the current 4G. It is likely to use frequency bands higher than existing bands to have wider bandwidth for high throughput services. How efficiently use such high frequency for full mobile services is one of the key topics.
This presentation will introduce 5G system field trials using 28GHz band. It shows successful hand over between scanning tracking beams under 200km/h mobile speed and the maximum user throughput of 13Gbps more.
Abstract 2 (Day 2, Session 2)
5G System Development and Use-Case Trials
Mobile communications service are widely penetrating to all the society as the key infrastructure. The development of the “5G” mobile system is pushed forward all over the world for a service launch of about 2020 as a target. 5G will be used for more diverse purposes not only for “Enhanced mobile broadband” but also “Massive-machine type communication” and “Ultra-reliable and low latency communication”. It necessary to investigate usage scenario of 5G in parallel to system development.
This presentation outlines the system development on leading-edge 5G and introduce several use case trials with partners.
