5G IntroduçãoO que é o 5G ?

Janeiro de 2012 a ITU-R aprovou a especificação do 4G.

Enquanto isso o dramático crescimento dos serviços de dados móveis desencadeou o estudo do 5G.


A industria ainda não chegou a um consenso sobre o que é o 5G.


Conjunto de padrões de comunicações móveis interconectados.

Era 2020.



5G Requisitos

(Boyd Bangerter, at IEEE Communications Magazine 2014) “The industry’s concept of mobile performance is evolving, and so are performance metrics”.

5G RequisitosQualidade de experiência de Usúario QoE

(Boyd Bangerter, at IEEE Communications Magazine 2014) “In order to provide a high QoE for services, 5G systems will need to be context-aware, utilizing context information in a real-time”.

5G RequesitosMaior Capacidade

(T. Nakamura, at IEEE Communications Magazine 2013)“Mobile data traf-fic has been forecasted to grow more than 24-fold between 2010 and 2015, and more than 500-fold between 2010 and 2020”.


(Woon Hau Chin, at IEEE 2014) “heavyweights such as Qualcomm and Nokia Siemens Networks are looking at technologies which will cope with traffic growth of 1000 times”.

5G RequesitosMaior Eficiencia Espectral

Tecnicas de Multiplo acesso Não Ortogonais:

CDMA-FMT.[9]

5G RequesitosMais Espectro

MmWave:

(Federico Boccardi, at IEEE Commnucations Magazine 2014) “While spec-trum has become scarce at microwave frequen-cies, it is plentiful in the mmWave frequencies ranging from 3 to 300 GHz”.


MmWave.

Bandas que estão a ser estudadas:

(Federico Boccardi, at IEEE Commnucations Magazine 2014) “28–30 GHz, the license-free band at 60 GHz, and the E-band at 71–76 GHz, 81–86 GHz, and 92–95 GHz”.


Radio Cognitivo.

5G RequisitosMenor Custo, Mais Flexibilidade

(Boyd Bangerter, at IEEE Communications Magazine 2014) “Cost and flexibility of deployment will also be important factors in 5G networks, requiring a shift toward software-based implementations and virtualization technologies”.

5G Requesitos

Menor Consumo de Energia.

Menor Latência.

Melhor Cobertura.

Maior Performance.

Etc...

5G Arquiteturas Propostas

“At the moment, the wireless industry has yet to reach a consensus on a unified view of future 5G network architecture. Some favor a more distributed network architecture with self-organizing capability, while others have advocated more centralized cloud-based access networks”.

5G Arquiteturas Propostas

Anchor-Booster, 3GPP. Cloud RAN, China Mobile. Device to Device.

Arquitetura Actual[1]

5G Arquitetura Proposta[1]

5G Arquiteturas PropostasAnchor-Booster

(3GPP TR 36.932, 2013) “In this architecture, the macro cell operates as an anchor base station, and is primarily responsible for control and mobility, while the small cell operates as a booster base station and is mainly responsible

for offloading data traffic”.

5G Arquiteturas PropostasCloud RAN

(China Mobile, 2010) “In scenarios where small cells can be connected to macrocells with low-latency high-rate (“ideal”) backhaul, the baseband signals from several hun-dred cells can be received and processed at a centralized server platform”.

Tecnologias Propostas

(Boyd Bangerter, at IEEE Communications Magazine 2014) “Several technologies expected to be key ingredients of 5G, ... are available today. Many others will be developed and deployed over the coming years.”

Tecnologias PropostasSmall Cell


(Woon Hau Chin, at IEEE 2014) “By reducing the size of the cell, area spectral efficiency is increased through higher frequency reuse, while transmit power can be reduced such that the power lost through propagation will be lower”


(Woon Hau Chin, at IEEE 2014) “Additionally, coverage can be improved by deploying small cells ... and offloading traffic from macro cells when required”


(Shanzhi Chen, at IEEE Communications Magazine 2014) “the increase of small cell numbers in the future may far exceed 100 times the current number”

Tecnologias PropostasVirtual Radio Access Network

O aumento das RAT(tecnologias de acesso a radio)

WiFi. LTE. WiGig Mm-Wave. Wearable devices RATs. Outras RATs M2M.

Tecnologias PropostasVirtual Radio Access Network

(Boyd Bangerter, at IEEE Communications Magazine 2014) “An integrated virtual radio network will enable joint management and simultaneous use of radio resources across different radio technologies to significantly improve radio capacity, and

enhance coverage and wireless link reliability”.

Tecnologias PropostasM2M

(Boyd Bangerter, at IEEE Communications Magazine 2014) “the Internet of Things concept contemplates a world where everything from alarm clocks to washing machines to automo-biles is connected through mobile-based machine-to-machine (M2M) communications”.

Tecnologias PropostasMassive MIMO e 3D MIMO

(Boyd Bangerter, at IEEE Communications Magazine 2014) “Advanced multiple-input multiple-output(MIMO) techniques are at the heart of achieving higher capacity for cellular systems.”

Tecnologias PropostasContext Awareness

(Boyd Bangerter, at IEEE Communications Magazine 2014) “In order to provide a high QoE for services, 5G systems will need to be context-aware, utilizing context information in a real-time manner based on network, devices, applications, and the user and his/her environment”.

Tecnologias PropostasContext Awareness

(Boyd Bangerter, at IEEE Communications Magazine 2014) “In the 5G Era, new ways to abstract and efficiently generate context information are needed, as well as new ways to share context information between the application, network, and devices”.

Tecnologias PropostasSoftware Defined Celular Networks

(Woon Hau Chin, at IEEE 2014) “Recently, there are also growing interests in both academia and industry to apply SDN to mobile networks”


(Woon Hau Chin, at IEEE 2014) “Wireless SDN is still at its infancy. There are a number of outstanding issues to be resolved before it can realize its full potential”


(Woon Hau Chin, at IEEE 2014)“Therefore, we believe that wireless or cellular SDN could be a possibility in future wireless networks”
