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.

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.
