Use cases have been grouped into families and use cases in the same family share similar

characteristic and requirements. The NGMN (Next Generation Mobile Networks) alliance has

developed 25 use cases for 5G as representative examples, which are grouped into 8 use

case families shown here below.

The ITU-R has identified 3 use case groups addressing different use case characteristics:

Enhanced mobile broadband (eMBB): addresses human-centric use cases for access to multi-media

content, services and data.

Ultra-reliable and low latency communications (URLLC): This use case has stringent requirements for

capabilities such as throughput, latency and availability. Examples include wireless control of industrial

manufacturing or production processes, remote medical surgery, distribution automation in a smart grid,

transportation safety, etc.

Massive machine type communications (mMTC): very large number of connected devices typically

transmitting a relatively low volume of non-delay-sensitive data. Devices are required to be of low cost, and

have a very long battery life.

4The different scenarios presented by the different organizations can be related to each other.

The IMT-2020 (5G) Promotion Group has proposed 4 technical scenarios for 5G that have

been indicated. They are in line with the 3 usage scenarios from ITU-R. The main difference

is that the eMBB scenario from ITU-R is divided into two technical scenarios, i.e., the

seamless wide-area coverage scenario and high capacity hot-spot scenario.

In the following, we summarize the main characteristics of 5G scenarios we believe satellite

can play a part in 5G:

• Rural/sub urban

• High Speed

• Extreme rural for the provision of minimal services over long distances

• Extreme rural with extreme long range

• Highway scenario

Complementation on wide areas of terrestrial urban microcells approach.

In December 2015 the 3GPP has started a study on scenarios and requirements for next

generation access technologies and 10 deployment scenarios have been specified for 5G

in march 2016.

• 7 have been proposed mainly for eMBB and include: indoor hotspot, dense urban, rural,

urban macro, high speed, extreme rural for the provision of minimal services over long

distances and extreme rural with extreme long range.

• For mMTC, 1 deployment scenario is presented and it concerns urban coverage for

massive connection.

• For URLLC 2 deployment scenarios have been identified. They include highway scenario

(for Internet of Vehicles) and urban grid for connected cars.

Value brought from satellite to 5GTypical value satellite bring to terrestrial telcos: complementation; augmentation

• Resilience in case of main link failure in support of emergency and for mission critical

services

• Ubiquity (beyond terrestrial coverage)

• Support to mobility (-> IoT)

• Backhauling

• Broadcasting/multicasting (with star scheme for huge amnount of data)

Key market verticals that will drive 5G satellite• Transport (Road, Rail, Aero, Maritime)

• Media & Entertaiment

• Public Safety (eHealth)

• Energy (offshore)

Commercial barriers to delivering of satellite 5G services• Need of agreement and integration with terrestrial players

• Access to space is no more an issue (weight, launch cost and cost/bit decreasing)

Techno barriers/abilitators to delivering of satellite 5G services• Regulatory topic / VHTS; miniaturization

Key partnership to gain traction in satellite 5GCooperation with terrestrial operators (fixed and mobile) or service providers

• Experiences on hybridization

• MiSE national bid for trials

• European trials

New LEO magaconstellations will improve the role of satellite in 5G development

They will offer a solution to ubiquitous service coverage:

• IoT global

• Low latency

• Unmanned vehicles as nodes of a globally moving internet network (connected cars)

and BRLOS

• Syncronization with Galileo’s time

Ka band spectrum

To protect or to share with terrestrial services for 5G:

• Differences between today’s and late 90’s constellations
