LTE AdvancedFrom Wikipedia, the free encyclopedia

LTEAdvancedis a mobile communication standard and a major enhancement of the Long Term Evolutio

(LTE) standard. It was formally submitted as a candidate 4G system to ITU-T in late 2009 as meeting the

requirements of the IMT-Advanced standard, and was standardized by the 3rd Generation Partnership

Project (3GPP) in March 2011 as 3GPP Release 10.

Background

The LTE format was first proposed by NTT DoCoMo of Japan and has been adopted as the international

standard.[2]LTE standardization has matured to a state where changes in the specification are limited to

corrections and bug fixes. The first commercial services were launched in Sweden and Norway in

December 2009[3]followed by the United States and Japan in 2010. More LTE networks were deployed

globally during 2010 as a natural evolution of several 2G and 3G systems, including Global system for

mobile communications (GSM) and Universal Mobile Telecommunications System (UMTS) (3GPP as we

as 3GPP2).

The work by 3GPP to define a 4G candidate radio interface technology started in Release 9 with the study

phase for LTE-Advanced. Being described as a 3.9G (beyond 3G but pre-4G), the first release of LTE did

not meet the requirements for 4G (also called IMT Advanced as defined by the International

Telecommunication Union) such as peak data rates up to 1 Gb/s. The ITU has invited the submission of

candidate Radio Interface Technologies (RITs) following their requirements in a circular letter, 3GPP

Technical Report (TR) 36.913, "Requirements for Further Advancements for E-UTRA (LTE-

Advanced)."[4]These are based on ITU's requirements for 4G and on operators own requirements for

advanced LTE. Major technical considerations include the following:

Continual improvement to the LTE radio technology and architectureScenarios and performance requirements for working with legacy radio technologiesBackward compatibility of LTE-Advanced with LTE. An LTE terminal should be able to work in anLTE-Advanced network and vice versa. Any exceptions will be considered by 3GPP.Consideration of recent World Radiocommunication Conference (WRC-07) decisions regardingfrequency bands to ensure that LTE-Advanced accommodates the geographically available spectrumfor channels above 20 MHz. Also, specifications must recognize those parts of the world in whichwideband channels are not available.

Likewise, 'WiMAX 2', 802.16m, has been approved by ITU as the IMT Advanced family. WiMAX 2 isdesigned to be backward compatible with WiMAX 1 devices. Most vendors now support conversion of

'pre-4G', pre-advanced versions and some support software upgrades of base station equipment from 3G.

The mobile communication industry and standards organizations have therefore started work on 4G access

technologies, such as LTE Advanced. At a workshop in April 2008 in China, 3GPP agreed the plans for

work on Long Term Evolution (LTE).[5]A first set of specifications were approved in June 2008.[6]Besid

the peak data rate 1 Gb/s as defined by the ITU-R, it also targets faster switching between power states and

improved performance at the cell edge. Detailed proposals are being studied within the working groups.

Proposals

The target of 3GPP LTE Advanced is to reach and surpass the ITU requirements. LTE Advanced should b

compatible with first release LTE equipment, and should share frequency bands with first release LTE. In

the feasibility study for LTE Advanced, 3GPP determined that LTE Advanced would meet the ITU-R

requirements for 4G. The results of the study are published in 3GPP Technical Report (TR) 36.912.[7]

One of the important LTE Advanced benefits is the ability to take advantage of advanced topology

networks optimized heterogeneous networks with a mix of macrocells with low power nodes such as

picocells, femtocells and new relay nodes. The next significant performance leap in wireless networks will

come from making the most of topology, and brings the network closer to the user by adding many of thes

low power nodes LTE Advanced further improves the capacity and coverage, and ensures user fairness

LTE Advanced also introduces multicarrier to be able to use ultra wide bandwidth, up to 100 MHz of

spectrum supporting very high data rates.

In the research phase many proposals have been studied as candidates for LTE Advanced (LTE-A)

technologies. The proposals could roughly be categorized into:[8]

Support for relay node base stationsCoordinated multipoint (CoMP) transmission and reception

Within the range of system development, LTE-Advanced and WiMAX 2, can use up to 8x8 MIMO and 12

QAM in downlink direction. Example performance: 100 MHz aggregated bandwidth, LTE-Advanced

provides almost 3.3 Gbit peak download rates per sector of the base station under ideal conditions.

Advanced network architectures combined with distributed and collaborative smart antenna technologies

provide several years road map of commercial enhancements.

A summary of a study carried out in 3GPP can be found in TR36.912.[9]

Timeframe and introduction of additional features

Original standardization work for LTE-Advanced was done as part of 3GPP Release 10, which was frozenin April 2011. Trials were based on pre-release equipment. Major vendors support software upgrades to

later versions and ongoing improvements.

In order to improve the quality of service for users in hotspots and on cell edges, heterogenous networks

(HetNet) are formed of a mixture of macro-, pico- and femto base stations serving corresponding-size area

Frozen in December 2012, 3GPP Release 11[10]concentrates on better support of HetNet. Coordinated

Multi-Point operation (CoMP) is a key feature of Release 11 in order to support such network structures.

Whereas users located at a cell edge in homogenous networks suffer from decreasing signal strength

compounded by neighbor cell interference, CoMP is designed to enable use of a neighboring cell to also

transmit the same signal as the serving cell, enhancing quality of service on the perimeter of a serving cell.In-device Co-existence (IDC) is another topic addressed in Release 11. IDC features are designed to

ameliorate disturbances within the user equipment caused between LTE/LTE-A and the various other radio

subsystems such as WiFi, Bluetooth, and the GPS receiver. Further enhancements for MIMO such as 4x4

configuration for the uplink were standardized.

The higher number of cells in HetNet results in user equipment changing the serving cell more frequently

when in motion. The ongoing work on LTE-Advanced [11]in Release 12, amongst other areas, concentrate

on addressing issues that come about when users move through HetNet, such as frequent hand-overs

between cells.

evices

At the time of its launch in 2007, LTE Advanced was not supported by any smartphone, but only by a sma

number of routers. The first capable smartphones wouldn't arrive until late 2013. While no smartphone is

currently capable of 1 Gbit/s+, there are smartphones that can reach 300 Mbit/s to 500 Mbit/s under idealconditions.
