Presentation by Yasuhiko Inuoe (NTT) on activities from ARIB/MMAC T-71 ad hoc (11-03/323r0)

Key points:

  • Chair of ad hoc is Matsumoto-san (Speednet). Purpose was to revise T-71 and generate T-71 Version 2.
  • Meetings were held Jan 23, Feb 25 & Mar 19 at which point work was complete.
  • The final version was available May 9 and is expected to be ratified on June 5.
  • There was extended discussion on the channelization content and plans for T-71. It was noted that 10 MHz channels are not included in T-71 Ver 2 but the ad hoc would continue to meet. Expectation is that Version 3 would address alternate channelization but there is no firm schedule for its release.
  • Preparation of TGj specification text should continue without waiting for further T-71 versions.

unlicensed operations and power levels.

Issues A and E will be discussed at 1 PM on Thursday.

Discussion on Issue C:

Peter Eccelsine will talk to Denis Kuwahara. This has

been resolved.

Discussion on Issue B:

Brainstorm on channel number schemes. Mostly by Peter.

Key off country code? Add new information element?

Use 201 as a 1st channel number (currently not used)?

This would act as an escape key.

Peter will prepare text on this idea.

Thursday, 16 May

Chair calls meeting to order at 1:05 pmThursday May 15, 2003.

Peter moves to modify item 2 on the agenda to allow for presentations

related to ballot comment during this session.

Bob Nielsen seconds, accepted by unanimous assent.

Discussion by Peter:

Peter proposes regulatory annex. Also the current beacon system

is not adequate.

Presentation by Peter:

Peter presents document 418r0, 11j Regulatory Classes. Proposes

country information element, using 201 as an escape code. Peter

has identified 11 regulatory class values for 4.9/5 GHz.

Comment by Bruce: this is a version of location-based services.

Presentation by Yasuhiko Inoue, document 322r2: "The 4 ms

Carrier Sense Rule in Japan" Fragmentation involves no carrier

sensing between fragments. Therefore a sequence of fragments

more than 4 ms is illegal. This is a problem in existing draft.

Problem is more severe at 10 M?Hz channelization.

Comment by Peter: references to Japan rules should be informative,

stating reference to rules as of the present time, because

rules may change.

Mark has a presentation.

Peter proposse a straw poll: If there are more than 24

people in the room at 3:40 PM, we agree to re-present any presentations

made in the 1 pm session.

No discussion. 13-0-0 straw poll passes.

Mark Webster's presentation: "10 MHz Chanelization Suggestion"

Document 431r0.
