Presentation #1: 12/0810r3 Proposed Resolutions on Misc PHY comments (Youhan Kim, Qualcomm)

Youhan presented

6606,6607, 6608, 6180, 6609, 6335

No objection to the resolutions to CID 6606, 6607, 6608, 6180, 6609 and 6335.

Presentation #2: 12/1039r0 Proposed Resolutions on Misc PHY comments– Part 2(Youhan Kim, Qualcomm)

Youhan presented

6610, 6322, 6611, 6612, 6613,

No comments

6614

Raja: This Note should be in the MAC clause and explain how to transmit in duplicate format.

Youhan: This is just to solve the comment and release the concern.

Raja: It is already in the spec, why do we add it here?

Youhan: Yes. There is nothing new. The Note here is more convenient for the reader that only read this clause.

Adrian: How about just invoking the table 22-2?

No objection noted to the comment resolutions to CIDs 6610, 6322, 6611, 6612, 6613 and 6614 as in doc 12/1039r1.

Presentation #3: 12/1036r0 D3 Comment Resolution, Brian, Part 3(Brian Hart, Cisco)

Brian presented

6201,

No comment

6200, 6397,

Youhan: What does the channel switch in Wider Channel Bandwidth mean?

Brian: It is the request for the report of measurement and change to new bandwidth.

Youhan: This is somewhat like BSS Load element.

Brian: BSS Load element is show the status of current BSS to STA. The load request is to request the frame including BSS Load element. I will check if there is any contradiction.

Youhan: When you send the Beacon request and scan in 80 MHz, what will you see?

Brian: There will be 20MHz Beacon in each 20MHz, and also 40MHz Beacon and 80MHz Beacon. It is different from 11n.

Youhan: So there is no rule that Beacon is only sent in primary channel?

Brian: I believe not.

No objection noted to the comment resolution to CID 6201.

Presentation #4: 12/1055r0 LB188 Comment Resolution (Clause 22.1)(Bo Sun, ZTE)

Bo presented

6400, 6401,

Eldad: Why is the paragraph there?

Youhan: It is better to change the text in line 37 into “A VHT STA shall support following VHT features”

Adrian: How about simply reject the comment?

Brian: Change “VHT features” to “clause 22 features”

6402, 6640,

Raja: This comment has been raised before.

Osama: To be consistent, you can reject it.

Brian: Frankly speaking, the sentence needs partly change.

Adrian: We got it from the PAR.

6328,

No comment

6329,

Eldad: MU PPDU doesn’t only mean the MU PPDU in VHT format.

Vinko: I will check the necessary changes to this comment.

Adrian: The sentence has to be kept because it is a key feature for this field.

No comment

6091,

Raja: Is there any bandwidth restriction for the data that polled by PS station.

Yong: No. There isn’t any rule. It is not TXOP. PS STA sending PS-Poll is not the TXOP holder.

Adrian: STA can send duplicate format PS-Poll to ensure the bandwidth.

Yong: PS-Poll does not have Duration field. It is hard to reserve the time of TXOP.
