Deployment/Migration Scenarios

•In 2020,

5G

will be launched

initially from areas, where higher performance is

required

– Both new RAT (Phase I) and enhanced LTE (eLTE) RAT are introduced to realize tight

interworking between lower and higher frequency bands

Before 2020

2020

202x

•In beyond 2020, deployment areas for 5G are gradually expanded

while

introducing additional technologies and frequency bands (=

5G+

)

– LTE (or LTE-Advanced) cell can be continuously used as eLTE cell for a long-time

•Stand-alone new RAT might be deployed in the future

for all use cases

5G will support both eMBB and MTC use cases

together with LTE evolution

5G Migration Scenario

 Initial Stage of 5G deployment:

5G services to be provided by interwork between eLTE with existing frequency bands and

New Radio(NR) with new frequency bands, i.e. Non Stand Alone(NSA)

 Later stage of 5G deployment:

NextGen CN to be deployed to provide services flexibly by architecture suit for slicing. NR

to be deployed for the existing frequency bands. Support stand-alone NR.

 Environment recognition (driving assistance)

 Distribution of hazard information, vulnerable road user warning

 Sharing of driving intentions and control information

 Environment recognition and

driving intention sharing requires

stringent latency and reliability.

 Broadband for wide area

recognition to improve comfort

and traffic efficiency.

 Compound use of V2V, V2I, V2N and V2P depending on the use case and environment/

situation.

 Clarification on the necessary composition of V2V, V2I, V2N and V2P

 Spectrum, business models
