1 doc.: IEEE SubmissionSlide 1 Project: IEEE P Working Group for Wireless Personal Area Networks (WPANs) Submission Title: [Proposed Resolution of D01 Comment S10-649, Mandatory channel at UWB low band] Date Submitted: [XX, September, 2010] Source: [Huan-Bang Li, Ryuji Kohno] Company [NICT] Address [3-4 Hikarino-oka, Yokosuka, Kanagawa, Japan] Voice:[ ], FAX: [:[ ], [{lee, Re: [Proposed Resolution of D01 Comment S10-649] Abstract:[propose a resolution to D01 Comment S10-649] Purpose:[This document is for the UWB comment resolution discussion for TG6 draft D01.] Notice:This document has been prepared to assist the IEEE P It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s). The material in this document is subject to change in form and content after further study. The contributor(s) reserve(s) the right to add, amend or withdraw material contained herein. Release:The contributor acknowledges and accepts that this contribution becomes the property of IEEE and may be made publicly available by P September 2010 H.-B. Li, R. Kohno, NICT

2 doc.: IEEE SubmissionSlide 2 Proposed Resolution of D0 Comment S Mandatory channel at UWB low band September 2010 H.-B. Li, R. Kohno, NICT Huan-Bang Li and Ryuji Kohno NICT

3 doc.: IEEE SubmissionSlide 3 D0 Comment S Original comment: Is it proper to use channel 2 as mandatory in low band? September 2010 H.-B. Li, R. Kohno, NICT

4 doc.: IEEE Submission Slide 4 Proposed Resolution(s) change to channel 3. The reason behind using channel 2 as mandatory is that waive of DAA at GHz (channel 3) was set at the end of It was considered to have no advantage to use channel 3 without waive of DAA. However, Japan is in pre-decision to waive DAA until the end of. Using channel 3 as mandatory can fully take the advantage and greatly reduce cost for implementation. September 2010 H.-B. Li, R. Kohno, NICT

5 doc.: IEEE SubmissionSlide 5 Discussion point (1) Channel 3 may ask for additional filtering at low band to fit for spectral mask. September 2010 H.-B. Li, R. Kohno, NICT

6 doc.: IEEE SubmissionSlide 6 Discussion point (2) LDC: throughput is not high enough Implementation: DAA vs. filter for mandatory If channel 2 is mandatory, both channel 1 and channel 3 still need filters. September 2010 H.-B. Li, R. Kohno, NICT

7 doc.: IEEE SubmissionSlide 7 Discussion point (3) Using channel 3 as mandatory is good for LDC devices in the sense of coexistence with 15.4a, which uses channel 2 as mandatory. Using channel 3 as mandatory is good in the sense of coexistence with 15.4a, If slotted ALOHA is used. Using channel 2 as mandatory is good in the sense of coexistence with 15.4a,, if CCA is used. September 2010 H.-B. Li, R. Kohno, NICT

8 doc.: IEEE SubmissionSlide 8 Conclusion Channel 2 vs. channel 3. Not against to use channel 2 as mandatory in the following sense: –International harmonization –Reduce the burden of mandatory implementation September 2010 H.-B. Li, R. Kohno, NICT
