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.

Highlight of Current Activities

• 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

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.

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 didnt 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.

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
