UK High Level 5G vision – Starting point

There is support for this to be focused on future user needs:

• “Always sufficient bandwidth to give the consumer the

perception of infinite capacity”

– DCMS UK spectrum Strategy

• “Always sufficient bit rate to give the perception of

unconstrained capacity”

– The same in technical language (Vodafone contribution to ITU)

– “Infinite” and “Bandwidth” could be misinterpreted

• However the current ITU document is more focused on

technology evolution

• Aim of group is to develop contributions to ITU, to ensure

that UK perspective is addressed

Progress so far

• Kick-off meeting on 17th March

– Agreed it is worthwhile to proceed with this task

• First working meeting on 7th April

– Agreement on main applications of 5G to be investigated

– Agreement on key parameters to characterise these applications

– Initial discussion on quantifying these parameters.

Potential applications of 5G

• The following were identified as key potential

applications for 5G

Data (inc. cloud and video files)

Voice

Multimedia

Critical Communications

Internet of things

• There is also a desire to consider long-term needs,

beyond the horizon for service evolution

– It is inherently not possible to analyse the capabilities needed

• Need initially to consider indoor and outdoor base

stations separately

• Because of different user density and mobility

• Applications will need to be merged, to reduce number

Short Range peer-to-peer

Low Latency (eg driverless cars)

Moving platforms (eg trains)

Parameters to characterise 5G

• Eight key parameters have been identified to characterise the

potential applications for 5G:

‘Sufficient bit rate’

Spectrum efficiency

Latency

Connection density

Device battery life

Capacity density (e.g. Gbit/s/km2 )

Coverage Reliability

Mobility

• Some are quantitative, others qualitative

• In addition, there are common objectives for all applications:

– Network energy efficiency

– Cost

• Eight key parameters have been identified to characterise the

potential applications for 5G:

Suggested

applications of

5G for study

These applications will need

to be grouped together, down

to around four for submission

to ITU.

This table shows a possible

starting point for the grouping

In 2G, 3G and 4G, the control

plane has been assumed to

use a subset of capabilities of

traffic channels.

However, for 5G, the control

plane might have separate

requirements

Examples of diagrams

• We plan to capture the results in a number of diagrams illustrating the

capabilities needed for groups of applications

• The following diagrams are examples of how the capabilities of 5G

mwill be illustrated.

• For each capability, the challenge of achieving increases with

distance from the centre

– i.e. latency reduces

– This will become clearer when the axes are added

• These will need to be defined to reflect the key parameters that we

agree and the values for them.

• The dotted lines show capabilities that exceed the requirements of

the core application for one application for one parameter

These diagrams are illustrative.

5G – Outdoor cell downlink

This diagram shows how

applications that are

similar but with a

difference in one

dimension can be

treated

This relates to services

provided by an outdoor

base station, whether

the user is indoors or

outdoors

Next steps

• Gain a common understanding of the meaning of terms

• Agree quantitative values or qualitative metrics for the key

parameters for the key applications

• Try to merge applications with commonalities

– To reduce the number in the ITU contribution

• Agree diagrammatic presentation

• Develop text describing broader implications of the Vision

• Develop ITU contribution to introduce these elements into ITU Vision

working document

Develop UK perspective - quantify parameters

• 5G Group meeting 8th May

ITU Contribution describing UK perspective

• Complete by end of May - one more physical meeting if needed

• IFPG PTD 9th June

• WP 5D 18-25 June, Canada

Develop document for wider UK readership

Develop UK perspective in second ITU contribution

• IFPG PTD 26 August

• ECC PT1 8-12 Sept (possible CEPT contribution to WP5D?)

• WP5D 15 – 21 October

Final UK comments on the ITU Vision document (probably in IFPG WGD)

• WP5D 28 Feb – 4 March 2015

– ITU document will be stable (upgraded to PDNR)
