Data Tsunami is coming • Currently an exponential growth of mobile data is observed* • More advanced devices with more capabilities
(smartphones, tablets, etc), as well as increased importance of machine generated data result in increased traffic generation
• Multi-device ownership, resulting in synchronization of data between devices
• Mobile Social Networking and User Generated Contents
* The data amount is doubling annually resulting in 1000× increase in the current decade, for the individual devices this means performance will increase 100×

+ YouTube Phenomenon
1% Rule (Internet Culture)
One will create content, 10 will "interact" with it (commenting or offering improvements) and the other 89 will just view it.
90-9-1 Principle 1% of people create content, 9% edit or modify that content, and 90% view the content without contributing.

+Unbalanced Traffic Distribution
! Imbalance between the terminal type: in 2010, smart phone’s global penetration rate is 13%, while it contribute 78% traffic load from the mobile device
! Geographic imbalance: in 2009, more than 50% mobile service happened at home/office; while this percentage is 63% in China. Most of the data service happens in low mobility indoor and dense urban
! Monthly basic mobile phone data traffic ! Smartphone = 24 x phone ! Handheld Gaming Console = 60 x phone ! Tablet = 122 x phone ! Laptop = 515 x phone
![Page 43: Latest trends in wireless technology](https://reader034.vdocument.in/reader034/viewer/2022052618/554dc708b4c905bd488b51a9/html5/thumbnails/43.jpg)
+Information Access
! The “paperless society” will have a huge impact on
networks:
• media will be consumed in portable devices;
• daily commuters will need a lot of information on an
instantaneous basis.

+Release 12
3GPP time plan for REL-12 (decided in TSG #56 in June 2012): • Start: Sept. 2012 (TSG #57) • Stage 1 (requirements) freeze: March 2013 (TSG #59) • Stage 2 (functional description) freeze: Dec. 2013 (TSG #62) • Stage 3 (all details) freeze: June 2013 (TSG #64)
RAN Workshop on REL-12 & onwards held in June 11-12, 2012 in LlublJana, Slovenia: • About 250 participants • 42 presentations (http://www.3gpp.org/3GPP-News) from leading network operators
and manufacturers • Scope:
• Requirements • Potential technologies • Technology roadmap for Release 12, 13 and afterwards
(Note: Workshop covered also UMTS but inly LTE is considered here)

+Requirements for RAN in REL-12 ! Capacity increase to cope with
traffic explosion
! Energy savings
! Cost efficiency
! Support for diverse application and traffic type
! Higher user experience/data rate
! Backhaul enhancement
! 2010 " 2020: 500x more smartphones %& tablets; most data traffic indoor
! Network operations/expanding costs, eNB/UE power consumption
! New apps, M2M interworking, public safety
! User expects higher data rate for similar costs
! Can become bottleneck with larger data traffic increase
Requirements Impact

+ Potential Technologies identified by REL-12 Workshop
! A great majority showed interest in Small Cell Enhancement for LTE. Technologies proposed by many members:
! Interference coordination / management
! Dynamic TDD
! Enhanced discovery / mobility
! Frequency separation between macro and small cells with higher
frequency band, e.g. 3.5 GHz band for the small cells
! Inter site CA / macro cell assisted small cells
! Allows flexible data rate increase via carrier aggregation
avoiding control signaling in small cells
! Wireless backhaul for small cell

+ Potential Technologies identified by REL-12 Workshop
! Very clear interest related to LTE Multi-Antenna/site technologies such as: ! 3D MIMO/beam-forming to allow beam control in both horizontal
and vertical directions
! New procedures and functionalities for LTE to support diverse traffic types proposed by many members:
! Control signaling reduction, etc. antenna array

+Summary
• Envisaged REL-12 topics (to be completed by June 14): • main topic: small cell enhancements cope with data traffic explosion
• further multi-antenna enhancements (3D MIMO, CoMP enhancements)
• D2D/public safety, offloading via Wifi, MTC will bring new aspects
• further enhancements of existing features (e.g. SON, MDT, CA)
• Future:
• further 4G enhancements expected before 5G (if 5G then led via ITU)
• driven by requirements from customers & network operators
• often triggered by availability of new spectrum and influenced by new technologies/applications and costs
