Stations) and Adjacent Systems in the 900 MHz and 1800 MHz Bands in Asia Pacific”
 Draft new report was finalized and approved by the AWG plenary.

Studies on User Equipment (UE) out-of-band emission levels and implementation
issues relating to usage of the band 698-806 MHz by the Mobile Service, including IMT
 Work on a Draft New Report that would capture results of these studies was
initiated. Draft New Report will be finalized at AWG-11.
 To assist the completion of the technical studies on UE out-of-band emission
levels and the finalization of the Report, it was agreed to re-convene its
technical correspondence group (CG) between AWG-10 and AWG-11.
 It was also agreed that it would be beneficial if 3GPP were informed of the AWG
studies relating to the development of UE out-of-band emission levels and the
schedule/timeline for completion of these studies. 3GPP Individual Member
companies participating in AWG will inform 3GPP of these AWG studies due to
no document approval procedure defined for LS to 3GPP at this stage.

New report on “PPDR Applications using IMT-based Technologies and Networks”
 Structure of the report was updated and finalized.
 It was agreed that draft new report will be finalized at AWG-13.
 LS to inform ASTAP of the latest work plan and etc. on PPDR was developed
and sent to ASTAP.

finalized at AWG-13.

Work item for SWG on SA&H
 Possible work items were discussed and identified as shown below.
•To develop a [Recommendation/Report] on the common frequency bands for
operation of short range devices
•To develop arrangements for the use of 5GHz bands on an unlicensed basis in line
with decisions of WRC-03 to meet the needs of private broadband systems
•Possible development of harmonized frequency arrangements in 806-894MHz band
 Input contributions to AWG-11 on the topic for consideration are expected.

Main Outcomes of WG-TECH

Work on Future IMT NW
 This work was initiated at AWF-9 and Questionnaire to gather information was sent out
to APT countries after AWF-9.
 Only two responses (P.R.China and Japan) were received between AWG-9 and AWG10.
 AWG-10 decided to re-send the same Questionnaire with notes for clarification.
 Detailed review of received responses will be conducted at AWG-11.
 Review of presentation materials used in ITU-R Regional Work Shop was conducted
and the result of review was noted in the meeting report of TG-IMT. This will be utilized
in developing the work plan on Future IMT NW in the next meeting.

Work on IMT technology
 New study item proposals on Adaptive Antenna Systems, Convergence of RAN, and
Heterogeneous Networks (HetNet) were received from Huawei and China Unicom at
AWF-9. AWF-9 carried forward these study item proposals to AWG-10 for further
considerations. Questionnaire on HetNet was sent out after AWF-9.
 Based on discussions about carried forward documents and other input documents to
AWG-10, it was agreed to initiate a new study item on the future development of IMT
technologies. The scope of this study is not limited to above three technologies.
 Related work plan and possible deliverable were discussed and agreed. APT report on
this study will be finalized at AWG-13.
 Responses to Questionnaire on HetNet received until AWG-10 were carried forward to
AWG-11 for review.

Main Outcomes of WG-TECH

Work on ITS
 Draft new report on “The Usage of ITS in APT Countries” was finalized and approved
by the AWG plenary.
 It was confirmed that this new report needs to be updated based on additional
information.

Work on SRD
 ToR of TG SRD was updated based on contribution from TG SRD chairman.
 Two work plans were developed to create the following deliverables;
• Recommendation/Report on “The Common Frequency Bands for Operation of
SRDs”
• Report on “Status of Introduction, Application, Issues and Technology for SRDs”
 Questionnaires asking for
• Regulatory status for the frequency bands specified in the preliminary draft new
Recommendation ITU-R SM.[SRD]
• Status of introduction, application, issues and technology for short range devices
were developed and approved to be sent out to APT countries

Work on CRS/SDR
 Questionnaire on SDR & CRS was developed at AWF-9 to survey current status of
service introduction/development and regulations. This was sent out to APT countries
and the deadline of response submission was set to AWG-11.
 Review of received responses was conducted at AWG-10.
 Frame work of CRS/SDR Questionnaire report was discussed and agreed.
 CRS/SDR Questionnaire report will be finalized at AWG-11.


General guideline on new study items
 WG-TECH had discussions about general guideline on developing a new study item.
• General Guideline on developing a new study item at AWG
– When a new study item is initiated, each deliverable should be identified with
a micro workplan which includes a responsible group, the document type,
the scope, the purpose, timeline and etc.
– Technical discussion in relevant external organizations need to be
considered in order to avoid unnecessary overlapping of work
 Closing plenary approved the above guideline proposed by WG-TECH.
 It was agreed that this guideline will be incorporated into the working procedure of
AWG in the future.

Next meeting
 In closing plenary, APT secretariat tentatively announced that AWG-11 will be held
during 11 - 14 October in Thailand.
 As a result of coordination after AWG-10 to avoid schedule overlapping with other
meeting, AWG-11 is likely to be held during 14 - 17 September in Thailand.
