• Work in 3 GPP is organized around the concept of release which can be defined as a complete set of functionalities for a full cellular network allowing new set of services to be deployed by operators • After completing a long evolution of the Wideband CDMA radio technology, 3 GPP decided to work on a new concept of radio technology to allow further evolution having in mind a long term evolution. LTE was born. But this does not stop completely parallel evolution of the WCDMA 6

LTE Standard • Layer 1 specification – It can be separated in 2 parts

LTE Standard • Layer 1 specification – It can be separated in 2 parts • First part resulting from the work in RAN WG 1 dealing with the description of the physical layer is now subject to the correction phase since last term. Functionalities described are complete and no major changes are expected. Set of specification contained in 36. 2 xx series • Second part mainly concerning the Requirement and the Performances still need to be completed but this is already considered as complete at 60% level. It is anticipated that this should be completed in December 2008. This work is mainly in the hand of WG 4. This is a key activity as it is the premises for the tests activities. Set of specification contained in 36. 1 xx series 9

• User Equipment Testing activities – WG 5 is in charge of defining the test specification for the User Equipment designed by 3 GPP. This covers the two following aspects: • Tests of the User Equipment part covering the Radio Interface (Access Stratum) • Tests of the User Equipment part covering the User/Core Network interface (Non Access Stratum) • Work has already started. Discussion on the priority of test development between TSG RAN and the Working Group started in June and are still under way 11

LTE Advanced • ITU-R is currently investigating 4 G and has solicited all organization for proposing technology as candidate for radio interface • 3 GPP had recently organized two workshops to examine this request • At the last plenary it has been decided to answer to ITU-R with an evolution of the radio technology already proposed in as an IMT 2000 technology: LTE • Here follows the foreseen evolutions already under study in 3 GPP 18

 • Main Characteristics for LTE Advance – The objective of Further Advancements for

• Main Characteristics for LTE Advance – The objective of Further Advancements for EUTRA is as follows: • Define a framework for further advancements of EUTRA and E-UTRAN (to be referred to as Advanced E -UTRA and Advanced EUTRAN considering: • The time schedule of ITU-R • That the work on Advanced E-UTRA and Advanced E -UTRAN must not introduce any delay to the completion of the Release 8 specification of E-UTRA and E-UTRAN • That the general enhancements of specifications for Release 8 E-UTRA and E-UTRAN are maintained and progressed in a focused and efficient manner. 19

 • Define requirements for Advanced E-UTRA and Advanced EUTRAN based on the ITU-R

• Define requirements for Advanced E-UTRA and Advanced EUTRAN based on the ITU-R requirements for IMT-Advanced as well as 3 GPP operators own requirements for advancing Release 8 EUTRA AND E-UTRAN considering: • E-UTRA radio technology and architecture improvements • Support for all radio modes of operation • Interworking with legacy RATs (scenarios and performance requirements) • Backward compatibility of Advanced E-UTRA and Advanced EUTRAN with Release 8 E-UTRA and E-UTRAN i. e. – an Release 8 E-UTRA terminal can work in an Advanced E-UTRAN, – an Advanced E-UTRA terminal can work in an Release 8 E-UTRAN and – non-backward compatible elements could be considered based on RAN decision • Newly identified frequency bands and existing frequency bands, and their advantages and limitations, in particular, the consideration of the WRC-07 conclusions, to ensure that Advanced E-UTRA can accommodate radio channel bandwidths commensurate with the availability in parts of the world of wideband channels in the spectrum allocations (above 20 MHz) and at the same time being mindful on the need to accommodate those parts of the world where the spectrum allocations will not have availability of wideband channels 20

• Identify potential solutions, technologies for the Advanced E-UTRA and Advanced E-UTRAN. The study areas include: • Physical layer • Radio interface layer 2 and RRC • E-UTRAN architecture • RF, including Aspects of wider channel bandwidth than 20 MHz • Advanced system concepts • To develop documents that will serve as a basis for the documentation to be submitted to ITU-R to provide the 3 GPP proposals for IMT-Advanced: • An “Early Proposal” submission that would be sent to ITUR, to be agreed at RAN #41 (9 -12 September 2008), for submission to WP 5 D #3 (8 -15 October 2008). 21

– A “Complete Technology” submission that would be sent to ITU-R, to be agreed at RAN #44 (26 -29 May 2009), for submission to WP 5 D #5 (planned for 10 -17 June 2009). – A “Final” submission to incorporate updates, additional specific details or feature additions, and the required self-evaluation that would be sent to ITU-R, to be agreed at RAN #45 (22 -25 September 2009), for submission to WP 5 D #6 (planned for 13 -20 Oct 2009). 22

RAN#41 9 -12 September 2008 in Kobe, JP • Have a verification that the 3 GPP requirements are equal or exceeding the ITU-R requirements • Update 3 GPP LTE-Advanced requirements according to the verification results if needed • Make an early submission of the 3 GPP concept to the ITU-R IMTAdvanced process 2007 2008 LTE 2009 2010 2011 CR phase #38 #39 WS #40 #41 #42 #43 #44 #45 #46 #47 #48 #49 2 nd WS Study Item #1 #2 Circular letter amendment with requirements and eval. methodology from WP 5 D #2 #3 #4 Work Item #5 #6 #7 #8 #9 #10 #11 #12 Proposals Evaluation Consensus Specification 23
