One5G D2.1 – Scenarios, KPIs, use cases and baseline system evaluation.

One5G has just delivered its D2.1 on “Scenarios, KPIs, use cases and baseline system evaluation. It describes the progress made in ONE5G project on the definition, characterization and quantitative analysis of a set of most promising use cases, and their corresponding services, that are identified for 5G beyond 3GPP Release 15. Strong focus has been put on the ability of 5G to address a variety of scenarios and verticals. Henceforth, views from Industry were taken into consideration prior to agreeing on the use cases.

A set of six core use cases is presented followed by three additional associated use cases. The core use cases comprise those services that are considered most attractive for 5G and that will be technically covered in the project, by means of suitable analyses, simulations and Proof of Concepts (PoCs). The associated use cases comprise a collection of very interesting services, where some have recently gained traction within 3GPP. These will also be technically covered, although with a lower depth and without any related PoC. In parallel, a set of Key Performance Indicators (KPIs), suitable Key Quality Indicators (KQIs) are also introduced as a very convenient means to characterize the end-to-end performance. Further work will be conducted and presented in the deliverable D3.1 around the KQI concept.

The key conclusions of this work can be highlighted in the following points:

• A significant number of use cases involve very stringent requirements, particularly in terms of high reliability and low latency.
• Some industries seem to require more stringent values for latency and reliability than the ones currently considered in 3GPP. Presenting suitable contributions to Standards is among the most important objectives of ONE5G, in order to ensure that the requirements set by vertical industries are sufficiently covered by Standards Development
  Organizations (SDOs).
• Further work is needed to properly characterize some of the selected use cases in terms of traffic models. Traditional traffic models for FTP, video, and multimedia sources
  cannot be applied to some of the described services, particularly those involving machines, factories and critical systems.
• Many of the identified use cases actually involve a mixture of enhanced Mobile Broadband – eMBB, massive Machine-Type Communications – mMTC and UltraReliable Low-Latency Communications – URLLC service categories. The traditional division between the three categories proves to be unrealistic when it comes to the new and most advanced use cases, like e.g. time-critical processes or assisted, cooperated and tele-operated driving.
• Even if the current progress of New Radio in 3GPP Release 15 has been remarkable to date, most technical work has focused so far on eMBB with little support of other, less traditional, use cases related to vertical industries. Hence there is an urgent need for presenting technical enablers to support these more stringent requirements of novel 5G use cases, which can influence standardization towards Release 16.
