TTA Activities on IMT-Advanced standardization

1. Global Standards Collaboration (GSC) 14 TTA Activities on IMT-Advancedstandardization DJey KIM (kdj@tta.or.kr) TTA

2. Highlight of Current Activities • ITU-R WP5D invited technology submission for IMT-Advanced standards. • 3GPP and IEEE presented their intention to submit LTE-Adv. and IEEE 802.16m during past WP5D meetings through initial submission at Feb. WP5D meeting. • 3GPP submitted detailed technology description at June WP5D meeting. • 13 evaluation groups were registered as independent evaluation groups in order to evaluate candidate technologies against IMT-Adv minimum requirement. • Detailed evaluation will be discussed in 7th & 8th WP5D meetings in accordance with ITU-R WP5D schedule.

3. TTA are actively involved in the IMT-Adv submission and evaluation activities. TTA endorsed LTE-Advanced submission as an organization partner of 3GPP at June WP5D meeting TTA also supports IEEE 802.16m technology for IMT-Advanced candidate technology. TTA registered as independent evaluation group, and provided technical contributions to WP5D e.g., C-code implementation of channel model, and clarification of channel model. TTA has actively participated in CJk-B3G collaboration. AWF and 3GPPs collaboration were agreed as work scope. SIG on Evaluation was established. 10 Joint contributions were made toward WP5D so far Highlight of Current Activities 3 Geneva, 13-16 July 2009

4. Proposed Strategic Direction • It is very important for ITU-R WP5D to manage the IMT-Advanced standardization process on time. • Broadband networks are demanded for high-capacity services on newly identified spectrum at WRC-07. • Based on timely IMT-Adv. Work completion, WRC-11 preparation can be smooth • This concludes that IMT-Advanced standardization process should be maintained in a transparent and efficient manner. • The progress of works should be well documented • The works of proponents and evaluation groups should be well organized.

5. Challenges • The difference of evaluation results • Multiple evaluation methods are specified for different perspectives of evaluation for IMT-Advanced RIT or SRIT. • ITU-R M.2135 didn’t specify every details on evaluation methodologies with consideration of different conditions required by different technologies. • The different understanding or implementation of evaluation methodology described in the Report ITU-R M.2135 by different evaluation groups. • It is difficult to calibrate evaluation methodologies among evaluation groups taking into account time and resource. • The ambiguity of consensus building(Step7) • After compliance assessment with minimum requirements at Step 6, consensus building and decision (step7) will begin. However, there is no clear definition & guideline on how to achieve objectives of “consensus building”.

6. Next Steps toward IMT-Adv. Standardization • The efficient work under IMT.RADIO • Although scope and work plan for IMT.RADIO was proposed at the previous WP5D meeting, there are still different views. • However, TTA is of view that IMT.RADIO is needed for an interim document to smoothly connect evaluation discussion to ITU-R M.[IMT.RSPEC] development. • Therefore, TTA would like to propose that IMT.Radio should be developed towards a new IMT-ADV document under current workplan in order to facilitate consensus building process, while comprised of the summary of discussion on the evaluation of each candidate RIT/SRIT
