Comment Resolution Submissions

11-11-0071r0 presented by ChaoChun Wang (MediaTek)

John Barr asked if the presenter is using the same document version as what is on the server because there seems to be some minor discrepencies. ChaoChun responded that he might have accidentally changed the text but it should be the same as what is on the server.

John Barr asked about some poorly formed grammar in the text and asked that more time be given to review the text before it is motioned to be accepted.

James Yee (MediaTek) commented that the references to the parameter ammWavePPDUMaxTime are in fact not typos, but the capitalization should be aMMWavePPDUMaxTime, but the editor should be able to make the corrections as needed.

11-10-1456r0 presented by Solomon (Intel)

Eldad asked for clarification for text on Page 4 (9.23.6.5.1), suggesting editorial changes.

Carlos suggested changes to address Eldad’s concerns.

John Barr started to comment but then said he needs more time to look at it.

Solomon will saved changes to 11-10-1456r1. Eldad asked all to review and comment.

John asked until when this will be tabled? Eldad explained that this is not a motion so there is nothing to table. Eldad will give everyone until tomorrow to review the document and provide comments.

Eldad further comments on the text changes for resolving CID#643

11-11-0078 presented by Chris Hansen (Broadcom)

BRP Comment Resolution for CID 125

John Barr commented on if Preamble should be capitalized. Chris said he will make the change and upload r1.

John Barr commented on LDPC (21.5.3.2.2.2) that certain values should be represented using parameter names instead.

Chris will upload an r1 with the suggested changes for further review.

Eldad said he wouldn’t leave it to Carlos to make the remaining changes.Chris said he will make all the changes instead.

Kato (NICT) asked about Tx EVM (21.4.1.1.1). Why mention rake receiver or equalizer? Eldad: this is similar to 11n where the spec specifies the use of zero-forcing equalizer (20.3.21.7.4).

Ian Wang (National Instruments), the inclusion of rake receiver is the confusing part.

Minutes of TGad session – MondayJanuary17th, 13:30 – 15:30

Eldad called the meeting to order at 1:30.

Added to agenda:

11/0079 by Carlos.

Comment resolution contributions

11/0090r0 presentation by Ganesh (Intel): FST in TVWS

Solomon asked how signaling is done between Mode I and Mode II devices. Messages or beacon? Ganesh: beacons. Modes also established via FCC certification.

Kato asked a question.

Kato commented that this is a TGad only feature but it is useful for other bands as well.

Carlos explained that FST is actually defined to work with bands other than DBand.

Sai asked about if the state machine on slide 5 covers the case of starting off with one Mode I device.

Ganesh explains the definition of Mode I and II devices.

Solomon asks if there is anything specific to TVWS in the proposed action frames and why the proposed handshake is necessary.

John Barr comments that since this presentation does not correspond to a technical comment, discussion should be limited. If this is an internal Intel discussion then it should be taken elsewhere. Eldad explains that this is within the scope of the agreed upon agenda, which includes comment resolution and other topics. Eldad as chair has decided to allow this presentation.

AlanBerkema (HP) asks about handling of failure.

Strawpoll discussions:

Alan (HP) commented.

John Barr commented that what is required for TVWS is out of scope. Eldad:

Strawpoll #1: did not run.

Strawpoll #2: 5 yes, 9 no, 23 abstain.

Al Petrick (Al Petrick & Assoc) commented that this deserves further consideration.

11/0070 presented by Solomon

Eldad made an editorial comment about “containing this SP is transmitted”. Eldad will consult Adrian about the proper editorial change since the group was not able to come to a conclusion.

No further questions.

11/0072r0 presented by James (MediaTek)

Kato (NICT) asked what the throughput reduction is by allowing MCS0. James: it is already allowed in general, the 2st 2 changes only apply to corner cases.

Kato questioned the impact of the deleted requirements. James: the proposed deletions only affect A-MPDU.

11/0079r0 presented by Carlos on Clause 10 (MLME) changes

No questions.

Will place this on the motion list for tomorrow.

For tomorrow’s PM1 session, we will start with review of changes made to contributions already presented.

Presentation 11/0070r1

Presentation 11/0109r0

Discussion on antenna definition. John asked if where “antenna” is in the text if it changes to “Dantenna”. Assaf responded that “antenna weight” and “sectorantenna” are not changing, for example.

Presentation 11/0118r1

Issue 1: Discussion on TX time. Based on Solomon’s comments, instead of “0,SC” and “0,OFDM” it becomes “0 and SC” and “0 and OFDM”.

Below the formula on pg 2 instructions to the editor were changed. “TGad Editor: replace 20 in the above formula…”. Assaf also proposed to fix aTdata definition. “TGad Editor: replace the Tdata definition for SC with (512xNblk+64)xTc”
