2000 Enhancement
Officially IMT-A is 4G. But people call LTE as 4G, since there is a large change from 3G.
What will be 5G then ?
Nobody knows yet 3
My view on Generation technology
Start from limited area
Cover the whole area
Replace the previous generation
If there is a technology called 5G, it must be applicable to Macro Cell
4
Requirements to future Macro Cell technology
Very high flexibility, although many people say higher bit rate

Frequency allocation to mobile operators in Japan

Total: 500MHz 17% of spectrum below 3GHz Small portion compared with industry size

Current wireless systems • Below 3GHz, many different usage
– Broadcasting (TV, radio ) – Special Mobile Radio
• Ship, Railway, Taxi, Truck, Electricity, Gas – Public radio
• Military, police, ambulance,・・・ – Satellites
• LEO, Mobile satellites, GPS – Amateur radio – Wireless LAN, PAN – And so on
• Too many systems !
7
From national economy viewpoint
• Government should maximize economical value of spectrum
• Mobile systems are far more spectrum efficient than other systems – Late comer – Very high traffic demand compared with spectrum
allocated • Each system has its own requirements, but many
of then can be covered technically by mobile systems
8
SMR system trends
• SMR systems are based on either TRTRA or iDEN, – Police, ambulance, disaster warning, train, ship, taxi,
electricity, gas,,,,
• They need to change to broadband systems • There are many independent SMR systems, each
of them has a small chunk of spectrum – This makes broadband difficult – Infrastructure cost is high, because many overlapped
coverage by independent systems
9
SMRs should adopt LTE for broadband
• LTE can provide wireless broadband service with high spectrum efficiency, much higher than SMRs
• Cellular systems will converge to LTE – Because of its market size, cost of equipment will
come down , even if it is complicated • LTE will keep evolving
– Big industry effort is spent on 3GPP to make LTE system better
– Even if some function is not in LTE now, it will be included in the future

Additional requirements to LTE
• Most SMRs require exclusive spectrum resource – This can be realized appropriate resource allocation.
TDMA is an example – It can be introduced to LTE – High reliability is also required
• Many SMRs require group call function – LTE already have eMBMS
• Some SMRs require strong security – LTE security is reasonably strong – If necessary, it can be enhance by higher protocol
13
Running LTE SMR (1)
• Currently, SMR license is divided into small pieces – Each company has 100KHz or 200KHz band
• A new operating company, handling many SMR license should be established and that operator should deploy broadband LTE – FirstNet is a good example – The operator should guarantee traffic to previous
license holders
• Several business models are possible
14
Running LTE SMR (2)
• There will be surplus frequency resource for new services since LTE spectrum efficiency is higher than current SMR
• Who will use the surplus resource on what, should be determined based on LTE network investment
• Business model should be deeply discussed
15
700MHz band allocation in US
Band 17: AT&T:LTE Band 13: Verizon:LTE Band 14: Public Safety Broadband Military, police, ambulance,, combined broadband Operator will be the FirstNet, part of government
16
Basic FirstNet concept
• A new band is allocated for broadband public safety in US – 99% area coverage of US
• FirstNet will provide service – FirstNet is a new US organization to run braodband public
safety • Technology is LTE • FirstNet will share the network with mobile operators
– To reduce the investment on base stations • US government made some functional request to 3GPP
17
Restoration form a disaster
18
・On emergency, communication tool is very important ・Special consideration should be paid on safety wireless
Introduction of Very Low Rate
Expand the coverage of non-damaged base station Activity has started in 3GPP under M2M WI
19
TV broadcast should be LTE based
• Currently, digital TV systems use their own transmission method – US, JAPAN, EU, China has their own standards
• All digital TV should be TD-LTE based – Two-way communication capability on TV will help a
interesting TV program a lot – Ratio can be 20 down, 1 up link – No technical difficulty exist – Global standard – Internet TV, Mobile TV will be much simpler
20
• TV White Space will be effectively used by two way communications
• Spectrum license holder can be broadcaster or other people
• 3GPP WI: L-band for Supplemental Downlink in E-UTRA and UTRA is a starting point of this, same as MediaFLO.
21
TV broadcast should be LTE based
PMSE should be LTE based
• PMSE (Program Making Special Event) is a communication system to deliver TV signal to center site
• If it is LTE based, it can use cellular LTE system, when spectrum resource is available.
• Currently, TV white space usage is under consideration.
• If both broadcasting and PMSE are LTE based, white space can be used very effectively
22
Wireless LAN can be LTE based
• Wireless LAN physical layer can be LTE layer 1 – Wireless LAN chip is already produced enough – Cost down effect LTE WLAN is not so large – Interwork between LTE-WLAN will be easier
• WLAN MAC should be CSMA-CA based – CSMA-CA is essential for unlicensed band – 3GPP may better consider introduction of CSMA-
CA to LTE
23
What should not be LTE based
• PAN (Personal Area Network) should not be changed to LTE – For a short distance communications, spectrum
efficiency is not an issue – In many cases, cost and power efficiency is more
important than spectrum efficiency for PAN – LTE is not designed for such a purpose
24
Summary on LTE convergence
• Most of the wide area wireless systems are better evolved to LTE
• This does not mean mobile operator should control most of the spectrum – There should be considerations on non-economic
value • If most of the systems deploy LTE, there will be a
vast economical benefit as a whole • US FirstNet is the starting point of this activity
– US may introduce LTE TV broadcasting as well
25
Conclusions
• High speed transmission in higher frequency is important, but we should look at lower frequency optimization as well
• LTE will be applied to almost all wide area wireless systems – US will lead this through FirstNet – Broadcasting will (may?) be LTE based as well
• Next change to mobile radio technology is to increase flexibility so that it can be applied to many other wireless systems

promising in the long-term future for higher/wider frequency bands– Non-orthogonal multiple access (NOMA) is a promising technology
for future cellular enhancements– Other technologies, e.g. new numerology/frame structure, new

Conclusion
My viewpoint on 5G Driving Force as Bowstring
• Take GROWTH as a key word
• In terms of
– Capacity per area
– Devices by IoT
Evolution Path as Bow
• LTE/LTE-A supports infrastructure
• Horizontal/Vertical HetNet
Revolution Path as Arrow
• Take NCT as a good opportunity for 5G
• Higher band radio such as millimeter wave technology
• Massive MIMO radio such as phase array technology

LTE on unlicensed spectrum - High Efficiency & Capacity complement
The natural advantages of LTE can improve the usage of unlicensed spectrum
• Higher coverage
• Higher peak rate
• Lower overhead
• Higher Tx efficiency
Capacity
Complement
High
Efficiency
As a good complement for LTE capacity, LTE on unlicensed spectrum can provide a better aggregating solution
• Unlicensed secondary carriers: as capacity/offload layers
• Control and management based on licensed primary carrier
• Inherit most of the merits of LTE: manageable/security/control/etc.
• Make it easy to adapt LTE into fully unlicensed utilization
Here, LTE on unlicensed spectrum is named to “U-LTE”

Key Point-2.1: Inter operator interference
Each operator has the equal right to access the unlicensed spectrum but without
coordinated geographical isolation among different eNodeBs.
Principal: Sensing or coordinating before using
It is beneficial to coordinate the occupying and releasing spectrum among different
operators
Solution: Over-the air seems the only feasible way for coordination
X2 or wired line are not available between different operators
Static agreement can not be flexible

Key Point-2.2: Principal on Coexistence with WiFi
Capacity Analysis :
When the load become higher, the throughput of standalone WiFi decreases while the throughput of standalone
LTE still increases due to the different scheduling mechanisms.
Besides the difference of scheduling mechanisms, due to HARQ, link adaptation based on receivers’ SINR, and
periodic transmission of common channels in LTE, it is deduced that if LTE directly coexists with WiFi on the
same unlicensed carrier, LTE will finally kick WiFi off when load is high.
