- 11. LTE Technology
LTE employs a new modulation technique on the radio interface - OFDM (Orthogonal Frequency Division
Multiplex), together with MIMO (Multiple Input Multiple Output) antenna technology
OFDM splits the information into multiple narrowband
subcarriers, allowing each of them to carry a portion of the
information at a lower bit rate, making OFDM a very robust
modulation, particularly in multipath scenarios, like urban areas
MIMO technology creates several spatial paths on the air
interface between the network and subscriber, so these paths
can carry the same or different streams of information, which
allows an increase in either the coverage (due to higher Signal to
Noise Ratio (SNR) at the receiver) or user data throughput

Voice service will be introduced as a second step
The One Voice initiative – announced on November 4, 2009, aims for industry agreement on
a harmonized way to implement voice and SMS over LTE, based on existing standards.
The GSMA VoLTE (Voice over LTE) initiative was formally announced at the Mobile
World Congress on 15th February 2010. In establishing the VoLTE initiative, GSMA has
adopted the work of the One Voice Initiative as the basis of the work to lead the global
mobile industry towards a standard way of delivering voice and messaging services for
Long-Term Evolution (LTE). Using IP Multimedia Subsystem specifications developed by
3GPP as its basis, GSMA have expanded upon the original scope of One Voice work to
address the entire end-to-end voice and SMS ecosystem by also focussing on Roaming
and Interconnect interfaces, in addition the interface between customer and network.

- 26. Spectrum for LTE deployments
An operator may introduce LTE in ‘new’ bands where it is easier to deploy 10 MHz or 20 MHz
carriers
e.g. 2.6 GHz band (IMT Extension band) or Digital Dividend spectrum 700, 800 MHz
Or in re-farmed existing mobile bands e.g. 850, 900, 1700, 1800, 1900, 2100 MHz
LTE 1800 looks the most promising from re-farmed spectrum
Eventually LTE may be deployed in all of these bands – and others later
2.6 GHz (for capacity) and 700/800 MHz (wider coverage, improved in-building) is a good
combination
LTE offers a choice of carrier bandwidths: 1.4 MHz to 20 MHz; the widest bandwidth will be
needed for the highest speeds
Availability of new spectrum, particularly in the 2.6 GHz and Digital Dividend bands (700, 800
MHz), is a crucial factor for LTE deployments in many countries, and the regulatory conditions, and
will directly determine deployment and service launch dates in most markets.

- Digital Dividend spectrum
- Excellent for rural coverage and in building coverage
The transition from analog to digital terrestrial television will release large amounts of spectrum
potentially for mobile broadband deployments – the so-called Digital Dividend
In 2005 the European Commission identified the release of the digital dividend in Europe as a spectrum
policy priority. The Commission later called for efforts to be made at the World Radiocommunication
Conference (WRC-07) to give mobile services the same status as broadcasting services
WRC 07 identified the 790-862 MHz band for mobile service in Europe, the Middle East and Africa
Some countries have now confirmed the availability of the 790-862 MHz band (subject to allocation
processes i.e. auction), including Denmark, Finland, France, Germany, Sweden and Switzerland
Germany recently became Europe’s first country to auction a package of spectrum which included
3 x 20 MHz digital dividend spectrum
Other governments in Europe will follow in 2010 and beyond
Many operators will deploy LTE in this band

Europe
Germany: After 224 rounds the spectrum auction ended on May 20, 2010 and covered 360 MHz
across 4 bands: 800 MHz (digital dividend), 1800 MHz, 2.1 GHz, 2.6 GHz. THIS WAS EUROPE’S
FIRST AUCTION OF DIGITAL DIVIDEND SPECTRUM. The 4 incumbents acquired 2.6 GHz
channels to be used for LTE. Telefonica O2, Vodafone and T-Mobile (but not E Plus)
additionally acquired 800 MHz digital dividend spectrum which they will use for LTE. The
800 MHz spectrum raised €3.576 billion, i.e. over 81.5% of the auction’s total value. Vodafone and
T Mobile are understood to be currently testing and deploying LTE in 800 MHz.
Netherlands: 2.6 GHz spectrum was auctioned in April 2010 and resulted in spectrum being
awarded to incumbents KPN, Vodafone, T-Mobile, and newcomers Ziggo 4 and Tele2. Unpaired
spectrum was left unsold.
Denmark: The auction of 2500-2690 MHz and 2010-2020 MHz spectrum was completed on May 10,
2010, with spectrum being awarded to Hi3G Denmark ApS; TDC A/S; Telia Nättjänster Norden AB;
and Telenor A/S. TDC has stated it could have a pre-commercial trial network running in June
2010. Information about the auction results is available here:

- 33. TD-LTE
The LTE market will include TD-LTE as well as FDD systems
Li Yizhong, Minister of Industry and Information Technology, stated that TD-SCDMA subscribers in China are
expected to reach 80 million by 2011. The China Mobile TD-SCDMA system covered 284 cities by end 2009.
China Mobile had 7.69 million 3G/TD-SCDMA subscribers total at end March 2010
TD-LTE is positioned as the next evolution in TD-SCDMA family and a natural progression
From 3GPP standards perspective: commonality with FDD
From vendor perspective: increasing use of software defined radio techniques
From operator perspective: spectrum availability, flexible base stations
TD-LTE trials now Early TDD Spectrum for LTE (TTD-LTE)
Timescales established for prototype, dual-mode
and multimode devices
In-service estimated as 2010-2011 IMT Extension Center Gap 2570–2620 MHz
TD-LTE being showcased at 2.3 TDD I.e. 2300 – 2400 MHz
World Expo, Shanghai from May 2010
Clearwire (USA) has requested 3GPP to standardize TD-LTE for operation in the band 2496 – 2690 MHz
In Japan, Softbank Mobile is reported to be considering TD-LTE as one of its options for the 2.5 GHz
spectrum the company has acquired.

- 34. TD-LTE
- comparison of FDD and TDD modes
FDD v TDD DL PHY differences
In the DL, the PDCCH contains a
number of extra bits specific to TDD
The P-SCH, S-SCH and PHICH
also differ from FDD. Other
channels are unchanged
FDD v TDD UL PHY differences
TDD operation affects the timing,
control and frame structure.
DwPTS: sent from eNodeB as part of synchronisation
GP: empty guard band
For the UL channels, the key UpPTS: sent from UE as part of synchronisation
changes are the PRACH channel
and sounding.

- 36. Migration options
Will HSPA+ deployments delay LTE rollout?
Many operators will invest in both HSPA+ and LTE. GSA sees no evidence of
HSPA+ uptake delaying commitments to deploy LTE. The success of
HSPA/HSPA+ in delivering mobile broadband will fuel demand to support
more customers and for even higher data throughputs including for new
applications, which LTE delivers. LTE brings the opportunity for additional
spectrum in Digital Dividend (700, 800 MHz) and 2.6 GHz bands, initially
giving comparable throughput capacity and performance, and will continue to
improve and also benefit from larger bandwidth deployments (up to 20 MHz).

- 37. LTE: a single global standard
LTE is on track, attracting global industry support. The first LTE systems launched in 2009
LTE is the natural migration choice for GSM/HSPA operators. LTE is also the next generation mobile
broadband system of choice of leading CDMA operators, who are expected to be in the forefront of service
introduction. A leading WiMAX operator recently announced it is shifting technology to LTE
As a result of collaboration between 3GPP, 3GPP2 and IEEE there is a roadmap for CDMA operators to
evolve to LTE
Successful handovers between CDMA and LTE networks have been demonstrated
The LTE-TDD mode (TD-LTE) provides a future-proof evolutionary path for TD-SCDMA
With LTE we have one single global standard, securing and driving even higher economies of scale and
importantly, simplifying roaming
