LTE Advanced Key Technology Messages

LTE Advanced is the evolution of LTEInitial LTE launches are based on 3GPP Release 8LTE Advanced is the evolution of LTE defined in

3GPP R10, targeted for completion in standards by Q1 2011. LTE R8 provides the following benefits:

LTE boosts data capacity in high demand areaso LTE will initially address data capacity in high demand areas where 3G provides

ubiquitous coverage as well as voice support.o Multimode LTE/3G devices provide seamless handover with 3G from day one.

LTE leverages new and wider spectrum, 10 MHz and beyond, and TDD spectrumo LTE is available in bandwidths below 10 MHz but offers limited performance

differentiation compared to evolved 3G.o LTE and evolved 3G provide similar performance (spectral efficiency and peak data

rates) when using the same bandwidth and same number of antennas (i.e., 2x2 MIMO). LTE Initial deployments will focus on data

o LTE, with its low latency and low overhead, is designed to support the entire range of IP

services including VoIP using IMS, but focus initially on data devices (dongles etc.)o Important mobility enhancementsforward handoverare planned for LTE R9.o Initial LTE handsets will rely on 3G (2G) for voice services

Qualcomm provides industrys first LTE/3G multimode chipsetso Qualcomm is in a unique position to support the worlds 1st LTE multimode and LTE

standards-compliant solution supporting all major 3G flavors and its evolution.

LTE Advanced leverages advanced topology networkThe next significant performance leap will come from leveraging topology by adding many low powernodessuch as femtocells, picocells, and relaysbringing the network closer to the user.

A network with a mix of macro cells and low powered nodes is also referred to as aheterogeneous network or HetNet.

LTE Advanced further improves the performance, simply adding new nodes obviously increase thecapacity, but LTE Advanced realize the full benefit of heterogeneous networksAdvanced TopologyNetworks providing the following benefits:

Significantly higher network capacitybeyond the gain seen by adding a node with LTE R8by better utilizing the low powered nodes and mitigate interference.

Ensures user fairness both within and between nodeso Adding new nodes creates new cell edges and users at the new cell edges may get

reduced performance without advanced interference management Improves cell edge user performance Extends range of nodes to better utilize of low power nodes (range extension) Enable the introduction of LTE femtocells

o Femtocells sharing the same spectrum as the macro network with restricted accessrequire advanced interference management

The new relay node extends coverage and improves capacity without wire-line backhaul expenseadvanced interference management further improves capacity and coverage.

Additional features such as SON (self-organizing networks) and minimization of drive tests will simplifydeployment of networks with many additional low powered nodes.

Advanced interference management: The two main features are 1) intelligent node association which extends the range to improvecoverage and capacity and 2) adaptive resource allocation which ensure fairness and improves performance by mitigatinginterference. In addition, LTE Advanced is also introduces additional interference management techniques such as coordinatedbeam forming. Multicarrier may also be used to enable adaptive resource allocation, in case time domain allocation is not possible

LTE Advanced leverages ultra wide spectrumLTE Advanced can leverage ultra wide spectrum 20 MHz up to 100 MHz through the multicarrier featureto further enhance the broadband experience.

Wider bandwidth is important to all wireless operators to continue to enhance the broadbandexperience since peak and user data rates scale with the bandwidth used.

Multicarrier is also a key feature for EV-DO Rev. B and HSPA+ to enhance performance in 5 MHzto 20 MHz spectrum bands.

Although most operators do not have access to 100 MHz of spectrum, LTE Advanced can provide 1 Gbpspeak data rates when leveraging 4x4 MIMO (and using 80 MHz of spectrum)

Operators will also leverage multicarrier to improve performance of advanced topology networks

LTE Advanced is the global 4G solutionthe leading IMT-AdvancedCandidateLTE Advanced is the leading candidate to meet ITUs IMT-Advanced requirement, the process that isdefining 4G:

3G was defined by IMT-2000 and formal approval as an IMT-2000 technology is a requirement inmany countries to get access to 3G defined spectrum.

ITUs IMT-Advanced definition is the next step after IMT-2000. The candidates where accepted inOctober 2009 for evaluation during 2010, acceptance end of 2010 and standards completion by

Q1 2011. LTE Advanced will meet or exceed the requirements set up by IMT-Advanced, e.g. peak and celledge spectral efficiency, the ability leverage wider spectrum and high peak data rates.
