ITU-R SG1 adopted a new Study Question at the last meeting and it is now circulated within ITU member states for approval. The draft new Study Question and the other input document related to THz technologies are briefly summarized. Purpose:Informing 802.15IGTHz on recent THz standardization activities at ITU-R Notice:This document has been prepared to assist the IEEE P802.15. It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s).

3. doc.: IEEE 802.15-13-0431-00-0thz Submission Status of a draft new Study Question New Question ITU-R SM.[THZ]. “Technical and operational characteristics of the active services operating in the range 275-1 000 GHz” was proposed at WP1A July meeting in 2012 and 2013. WP1A approved to submit a new Question to SG1 for adoption. SG1 adopted a new Question and send a circular letter (CACE/615) to ITU member states for approval on June 27. If there will be no objections from member states by August 27, 2013, the approval by consultation procedure will be initiated. July 2013 Akifumi Kasamatsu, NICT Slide 3

6. doc.: IEEE 802.15-13-0431-00-0thz Submission Summary and Remarks Administrations are invited to make a contribution on a working document towards a preliminary draft new Report ITU-R SM.[THZ_TREND]. If 802.15 THz group might wish to have specific frequency bands for THz communication systems above 275 GHz, it may be recommended to send a liaison statement to ITU-R and ask them whether those frequency bands can be used for active services without interference to passive services, by giving them technical and operational characteristics of THz communication systems developed by 802.15 THz group.
