IEEE P802.11 Wireless LANs LB 203 Clause 3 comment resolution Date: 2014-08-04 Author(s): Name Affiliation Address email Yongho Seok Self yongho.seok@gmail.com Interpretation of a Motion to Adopt A motion to approve this submission means that the editing instructions and any changed or added material are actioned in the TGah Draft. This introduction is not part of the adopted material. Editing instructions formatted like this are intended to be copied into the TGah Draft (i.e. they are instructions to the 802.11 editor on how to merge the text with the baseline documents). TGah Editor: Editing instructions preceded by “TGah Editor” are instructions to the TGah editor to modify existing material in the TGah As a result of adopting the changes, the TGah editor will execute the instructions rather than copy them to the TGah Draft. CID Commenter Page Clause Comment Proposed Change Resolution Fischer several are listed followed by a qualifier - it is not clear if the qualifier applies to all items in the list or only the last one Change "A 2 MHz S1G non-duplicate PPDU, S1G 1 MHz duplicate PPDU (TXVECTOR parameter CH_BANDWIDTH equal to CBW2)" to "A 2 MHz S1G PPDU or an S1G 1 MHz duplicate PPDU, with (TXVECTOR parameter CH_BANDWIDTH equal to CBW2)" - also make similar changes to the language in the 4MHz MASK PPDU, 8 MHz MASK PPDU and 16 MHz MASK PPDU definitions. Revised- Agree in principle. But, as an alternative, the proposed wording is to remove the "PPDU" in the sentence as in the same of 802.11ac. TGah editor to make changes shown in under the heading for CID 3882. Erceg several items are listed followed by a qualifier - it is not clear if the qualifier applies to all items in Change "A 2 MHz S1G non-duplicate PPDU, S1G 1 MHz duplicate PPDU (TXVECTOR Revised- Agree in principle. It is a duplicated CID with CID 3882.
the list or only the last one parameter CH_BANDWIDTH equal to CBW2)" to "A 2 MHz S1G PPDU or an S1G 1 MHz duplicate PPDU, with (TXVECTOR parameter CH_BANDWIDTH equal to CBW2)" - also make similar changes to the language in the 4MHz MASK PPDU, 8 MHz MASK PPDU and 16 MHz MASK PPDU definitions. TGah editor to make changes shown in under the heading for CID 3882. Kolze several items are listed followed by a qualifier - it is not clear if the qualifier applies to all items in the list or only the last one IS: "A 2 MHz S1G non-duplicate PPDU, S1G 1 MHz duplicate PPDU (TXVECTOR parameter CH_BANDWIDTH equal to CBW2)". SHOULD BE: "A 2 MHz S1G PPDU or an S1G 1 MHz duplicate PPDU, with (TXVECTOR parameter CH_BANDWIDTH equal to CBW2)". Revised- Agree in principle. It is a duplicated CID with CID 3882. TGah editor to make changes shown in under the heading for CID 3882. Kolze wrong word change "whereby" to "wherein" Revised- Agree in principle. But, CID 3426 addressed this CID by changing “whereby” to “in which”. TGah Editor: No change is needed. Roy Text reads: "1 MHz physical layer protocol data unit (PPDU): A Clause 24 1 MHz sub 1 GHz (S1G) PPDU (TXVECTOR parameter CH_BANDWIDTH equal to CBW1).1 MHz mask physical layer protocol data unit (PPDU): A PPDU Here and in the other similar definitions for 2MHz, 4MHz, 8 Mhz and 16MHz PPDUs, either eliminate one of the definitions, or change the second so that the difference between the two becomes easily discernible. Rejected- 1 MHz PPDU is a PPDU with TXVECTOR parameter CH_BANDWIDTH equal to CBW1. 1 MHz mask PPDU is a 1 MHz PPDU that is transmitted using the
that is transmitted using the 1 MHz transmit spectral mask defined in Clause 24 and that is a 1 MHz S1G PPDU (TXVECTOR parameter CH_BANDWIDTH equal to CBW1)." These are very odd terms, and it is not clear what the difference is sincePPDUs are not transmitted using "transmit spectral masks". They are transmitted by transmitters and the resulting waveforms either meet the spectral mask limits or they don't. 1 MHz transmit spectral mask. The difference between two terminologies is clear. Also, two terminologies are not unique for 11ah. 11n and 11ac are also defining two terminologies with the same wording. Fischer definition is incomplete to the end of the definition of VHT single MPDU add the following text: "and for which the response, if required, is an ACK, not a BA." Revised- in principle. But, in the case of 11ah, a NDP ACK can be used as a response of the VHT single MPDU. TGah editor to make changes shown in under the heading for CID 3878. Fischer wrong word change "whereby" to "wherein" Fischer article change "The Sub 1 GHz (S1G) to "A Sub 1 GHz (S1G) - change "that entered" to "that has entered" Revised- in principle. TGah editor to make changes shown in under the heading for CID 3880. access"
(VHT) basic service set (BSS), the 20 MHz channel adjacent to the primary 20 MHz channel that together form the 40 MHz channel of the 40 MHz VHT BSS.” If you think that this is a confusing wording, please change the definition of REVmc. Then, the TGah will also follow the updated definition. Shimada Append the difinition of "sub-channel" and/or "sub channel" and/or "subchannel". Unify the and the "sub channel" and "subchannel" as a "sub channel" and difine as, "A sub channel is a part of the operating channel in which beacons are transmitted or a unit channel in which SST(selective sub channel transmission) STAs may transmit." Revised- I agree in principle. But, a terminology of a subchannel has being widely used in the REVmc D3.0. TGah Editor: Replace with “subchannel” throughout the draft. Fischer confusing wording - the definition of secondary 1 MHz chanel begins with a single item and then has the phrase "that together form" - together with what? Only one has been identified at this point in the definition. Similar problem in similar definitions of secondary channels. not certain how to fix this Rejected- “secondary 1 MHz channel: In a 2 MHz sub 1 GHz (S1G) basic service set (BSS), the 1 MHz channel adjacent to the primary 1 MHz channel that together form the 2 MHz channel of the 2 MHz S1G BSS” The primary 1 MHz channel and secondary 1 MHz channel together form the 2 MHz channel of the 2 MHz S1G BSS. Same wording is used in 802.11ac. Please refer the below example defined in 802.11ac. “secondary 20 MHz channel: In a 40 MHz very high throughput
(VHT) basic service set (BSS), the 20 MHz channel adjacent to the primary 20 MHz channel that together form the 40 MHz channel of the 40 MHz VHT BSS.” If you still think that this is a confusing wording, please change the definition of REVmc. Then, the TGah will also follow the updated definition. Chu S1G_SHORT format is not just 2MHz wide change to "NDP MAC frame that is transmitted using the 2MHz S1G_SHORT format Rejected- NDP MAC frame can be transmitted in greater than or equal to 2MHz channel bandwidth. Chu TWT STA is not good name. Change TWT STA to TWT initiator (initiating STA) and TWT peer STA to TWT responder (responding STA). Both TWT initiator and responder are TWT peer STAs. The changes should be executed in draft. Rejected- Please refer a 9.42a (Target wake time). Definitions of TWT STA and TWT peer STA are very clear. Because clause 3 just follows the description of clauses 8, 9 and 10. If you want to change the name of the TWT STA, please submit the comment for 9.42a. At this moment, I haven’t find any technical reason the name change of the TWT STA is needed. Hunter "bi directional": why create another new term, when a standard English term will do? See the official English dictionary for IEEE standards (Webster's Collegiate 11th Ed). Replace "bi directional" and with "bidirectional" throughout the draft: here and page.lines: 7.63, 9.42, 10.34, 10.36, 149.7, 231.10, 285.54, 285.59, 286.7, 287.21 and 501.46. Accepted- Agree in principle. Propose: Revised for CID 3882, 3878, 3880, 3884, 3992, 3993, per discussion and editing instructions in 11-14/.
