Radio Access – Revolution
or Evolution
1. Classical 5G Revolution
– New generations replace older
generations
2. Complementary 5G (R)evolution
– 5G will complement 4G for specific
scenarios
3. Long-term 4G Evolution
– No new 5G air interface justified due to
insufficient
performance gain with new technologies
Do we need a new 5G air
interface?
New 5G air interface is justified if:
1. New air interface technologies with significant performance improvement can be
developed.
– Classically, this would be a change in the radio access scheme.
– A new access scheme has to show high improvements to justify the revolutionary step.
A 5G with high performance improvements would in the long term replace 4G.
. New deployment scenarios and services emerge, which cannot be
implemented with today‘s radio access schemes.
– New scenarios like machine-to-machine and car-to-car communications might require a redesign of the radio
frame structure and signalling to an extent, that it is more efficient to define a new air interface from scratch.
A 5G revolution motivated by new deployment scenari os and s ervi ces wou l d
complement 4G.
Data traffic growth factors
• Increase in mobile broadband subscribers
• More advanced devices like tablets and smart phones
• New attractive services
Prediction of data traffic growth for 2020 (relative to 2010)
• In the last year, traffic doubled in some networks
Total traffic growth could be 500–1000 times
Throughput in 2020 and
beyond
Throughput requirements
• Fairness: High throughput should be available over the whole coverage
area
• Latency: The user experience should be as good as in wired networks or
better
• Flexibility: Services with different QoS/throughput requirements have to be
supported
• Robustness: Maintain connectivity with minimum required throughput in
emergency scenarios like natural disasters
Target throughput for 2020 (relative to 2010)
Increase in
– peak,
– average and
– cell edge
throughput by a least a factor of 10
Energy consumption in
2020 and beyond
Green Radio
• Increase in RAN energy efficiency
– sustainable network operation
– reduced OPEX
Remark
• The power consumption of base stations does not
increase linearly with the supported peak data rates
Research directions
• New technologies with increased spectral
efficiency
• Heterogeneous network deployment with
efficient integration of smaller cells
• Traffic offloading
• New spectrum
• More flexible and efficient spectrum utilization
Other Future Research
• Interference Management
Self-clustering of cells for autonomous establishment of hierarchy, depending on
infrastructure
Usage of hybrids of centralized/decentralized interference management within clusters
with the additional option of fast, localized responses to bursty traffic
Interference management techniques in the context of direct D2D
• Mobility and Session Management
Strongly simplified signalling for neighbourhood discovery and handover
Novel session management and modified protocol stacks for service-aware radio access,
particularly in the context of M2M
Novel cell concepts such as “virtual cells”, or alternative connectivity concepts where a
device has uplink/downlink or data/control links to different cells, respectively
Handover from device-infrastructure-device to direct D2D and vice versa
• Network Infrastructure
Self-organizing infrastructure connectivity with a varying degree of aggregation
Network functionality to autonomously establish sub-networks
Application processing capability distributed through the network

Radio link technologies
• Investigate promising radio-link technologies (transmission waveform,
multiple access, etc.) and scenarios to increase the spectral
efficiency by more than factor of 2 in total
• New transmission schemes and multiple access schemes, e.g.
– Non-orthogonal signal waveform with faster-than-Nyquist
signaling, etc.
– Non-orthogonal multiple access assuming interference
cancelation
– Physical channel design such as reference signals and control
channels

New Air Interfaces,
Relay-based systems and
Smart antennas
• flexible, scalable and energy efficient air interface
design, maximization of both peak and cell edge data
rates and user capacity and guarantee ubiquitous
coverage in high mobility scenarios
• Enabling Technologies:
• smart antenna, MIMO and Relaying
• Intercell coordination and interference management
• System concept challenges: Cellular scenario, Open
Broadband Access, Meshed topologies
Device-to-device communications
and mesh networks
Elaborate the potential use cases (business models) of
Device-to-Device (D2D) communications/mesh networking
in cellular systems and identify promising architectures to
realize them.
D2D and mesh networks can be used to support maintaining
connectivity in emergency scenarios like natural
disasters
• Investigate radio interface for efficient support of D2D
communication and mesh networking e.g.,
– PHY and MAC layer transmission schemes
– measurement and synchronization
– interference management and radio resource management
Small Cells and Dense Heterogeneous
Deployments
System Capacity
– Deployments with smaller cells can more efficiently adapt to propagation and
scenarios and traffic needs
– Interference management and advanced receivers become more important in
dense small-cell deployments
Cost
– Especially in dense small-cell deployments not only the cost per base station but
also the cost for the network connection has to be considered
Energy Efficiency
– Low load situations allow for temporarily switching off more efficiently in
small-cell deployments
– Heterogeneous deployments with mixture of large and small cells are efficient
from an energy efficiency point of view

• new applications such as: Sensor networks and M2M
• very high speed broadband via short range wireless
• Spectrum availability under regulatory terms and financial
conditions allowing for:
• Innovative, appealing services for the end-customers
• A healthy competition so that the overall Wireless Eco
System will further flourish
• Thus Wireless will continue to be an important driver for our
future information society
