Release schedule & RAN features

LTE-Advanced

3GPP work is structured in releases

(REL) of 1-3 years duration

each release consists of several work

items (WI) and study items (SI)

even if a REL is completed corrections

are possible later

existing features of one REL can be

enhanced in a future REL

3GPP 2012

3GPP 2014

Dual connectivity for LTE

TR 36.842 looks at:Inter-node radio resource

aggregation, using radio resources

in more than one eNB in Scenario

#1 - Improving cell edge

throughputInter-node radio resource

aggregation, anchoring

connection to the macro cell while

boosting data-rate via the small

cell in Scenario #2Faster transitions for small cell

on/off to be based on discovery

enhancement and dual

connectivity (TR 36.872)


9/24


3GPP 2012

3GPP 2014

Small cell on/off

More eNBs implies higher interference level in the airinterface and more power consumption of the networks

Having dormant nodes will help address these challenges and

will allow available capacity to match the load

TR 36.872 considers the following schemes: Baseline schemes without any on/off

Long-term on/off schemes for energy saving

Semi-static on/off schemes

Ideal, dynamic on/off schemes

New Carrier Type study and introduction

3GPP 2014

Higher order modulation scheme(256 QAM)

Small cells proximity to UE brings opportunity for

higher order modulation, at 256 QAM downlink

TR 36.872 contains evaluation results of 256QAM

Concludes that downlink higher order modulation(256QAM) is beneficial in evaluated indoor sparse

small cell scenarios with low mobility

Possible Focus on 5.8 GHz band: widely available globally

Discussion on the combinations of licensed and unlicensed band

operation, Examples: LTE-U as TDD cell with FDD-TDD Carrier Aggregation

LTE-U as Supplemental Downlink (SDL), Thus no uplink in unlicensed band

Future Trends

Virtualization and SDN 3GPP discussions have started 03/2014, two potential areas impacted:

Management interfaces OAM needs to support virtualized infrastructure (SW

decoupled from HW)

Core architecture and future development trends Potential decomposition of some

functional elements

5G An integration of evolved and new technologies Ultra dense small cells

Wide area coverage

Some Conclusions

LTE and LTE-Advanced bring new

opportunities for Operators and a

growing number of segments

Small Cells are vital to sustainability

and growth

Band Aggregation provides the

necessary bandwidth to sustain

capacity and performance

5G is on the horizon and 3GPP

systems will be central to that
