FDD-LTE Radio Frame Structure• One FDD radio frame is 10ms, divided into 20 slots which one slot is

0.5ms.

• Each sub-frame consists of two equally sized slots

• One slot consists of 7 consecutive OFDM Symbols

Concept of Resource Block• LTE consists of time domain and frequency domain resources. The minimum

unit for schedule is RB (Resource Block), which compose of RE (Resource Element)

• RE has 2-dimension structure: symbol of time domain and sub-carrier of frequency domain

• One RB consists of 1 slot and 12 consecutive sub-carriers with normal CP configuration

Wireless broadband global forecasts

• Long term co-existence of different radio technologies

• 2G Networks will be maintained for Voice for long time (technology binding for frequency spectrums in Germany)

• Full use of 3G enhancements for Mobile Broadband (HSPA+)

• Need of Network modernization of early 3G deployments (deploy Multi-Standard Radio/Software-Defined Radio; reduce number of networks – reduce Opex dramatically)

• LTE 800-MHz deployment for broadband for white spots (start 2010/11)

• Frequency „refarming” after 2015? (Increase Frequency efficiency)

• Grab new spectrum to secure growth potential(2.6GHz/2.1GHz /1800/900(/800)MHz)

• Global View: 2G only networks will be upgraded directly to G4 for MBB

• LTE 2.6-GHz: Investigate in new deployment scenarios (no new Macro eNodeB sites, Micro/Pico/Femto in dense areas for ultra-MBB)

• Addressing Indoor coverage gap and further capacity growth

• Solve mobile backhaul challenges (migrate to Packet-Microwave in short term, Fiber-access to eNodeBs for long-term strategy)

MBB network providers are shifting the quality focus from KPI → QoS → QoE.

Four key challenges:

1. How to make the bit-pipe visible?

2. How to cope efficiently with the data traffic explosion and control the “bit-pipe”?

3. How to add value beyond the “bit-pipe” by leveraging network assets?

4. How to ensure end-to-end service quality, managing SLAs and delivering high QoE over complex MBB value chain and ecosystems?

Transforming bit-pipe into “High QoE” MBB Network & becoming User Experience Provider

From selling Flat-rate to QoE focus

The Laws & the Future Moore's law

Moore's law describes a long-term trend in the history of computing hardware, in which the number of transistors that can be placed inexpensively on an integrated circuit has

doubled approximately every two years

By 2020 we can expect a minimum 5-fold increase in

consumer electronics functionality
