5117 21 Regarding, "An HE non-AP STA support operation in 20 MHz channel bandwidth only", am I interpreting this correctly that an HE non-AP STA will only operate in 20 MHz? I'm guessing that tne intent is we want all HE non-AP STAs to support 20 MHz-only operation. If so, change the sentence to "An HE STA shall support 20 MHz-only operation" As in comment Revised. TGax Editor to make changes as shown in under all headings that contain CID 5117. 6928 21 The phrase: "An HE non-AP STA support operation in 20 MHz channel bandwidth only" does not seem to make sense as it seems to require that an HE non-AP STA is only allowed to support 20 MHz channel bandwidth, while the phrase directly above states the multiple bandwidths are allowed. Delegate the phrase: "An HE STA support operation in 20 MHz channel bandwidth only" or clarify what is intended by the phrase is to support Revised. TGax Editor to make changes as shown in under all headings that contain CID 6928. 6929 21 If the intent of the phrase: "An HE non-AP STA shall support operation in 20 MHz channel bandwidth only" is to say that a mode of operation of all HE non-AP STAs is to be able to operate as a 20 MHz only HE STA, then the phase should state that, Replace the phrase with: All HE non-AP STAs will support operation as 20 MHz only HE STAs. Revised. TGax Editor to make changes as shown in under all headings that contain CID 6929.
7007 21 Use of "shall" in Clause 4 (General description) seems to be inconsistent with existing Clause 4 text and also most of the new text added in P802.11ax/D1.0. Isn't this supposed to be descriptive clause where "STA shall support" would more likely be written "STA supports"? Furthermore, what exactly is "shall support operation in 20 MHz channel bandwidth only" supposed to say? That the STA is not allowed to use any other channel bandwidth than 20 MHz (e.g., neither 40 MHz nor 10 MHz or smaller)? That does not sound likely, but this could be interpreted as saying so.. Or is this saying that STA shall support operation at least in a 20 MHz channel? Or something else? It would be good to be more specific on what the exact mandatory behavior is for an HE non-AP STA. This applies to both lines 20 (5 GHz band) and 26 (2.4 GHz band). At replace "shall support" with "supports" (or something similar) on both lines and ideally, rewrite these to clarify the intent of this description of a mandatory functionality. Revised. Agree in principle. The proposed text uses “It is optional/mandatory…” TGax Editor to make changes as shown in under all headings that contain CID 7007. 7290 21 Chapter 4 provides a general description of the wireless system.. It should be written in a declarative but not normative language. Thus, "shall" should not be appeared in the sentence. Replace "An HE non-AP STA shall support operation in 20 MHz channel bandwidth only" with "Mandatory support for operation in 20 MHz channel bandwidth only by an HE non-AP STA". Revised. Agree in principle. The proposed text now uses “It is mandatory/optional…” TGax Editor to make changes as shown in under all headings that contain CID 7290. 8536 21 non-AP STA mentioned here should be 20 MHz only non-AP STA instead? Change "non-AP STA" to "20 MHz only non-AP STA" Revised. 80MHz-capable STA also supports 20MHz operation, so all non-AP HE STAs support 20MHz operation. This has been clarified in the proposed text.

7465 42 1024 QAM is also applicable to 2*996-tone RU. Change "Optional support for 1024-QAM on 242-, 484- and 996-tone RUs" to "Optional support for 1024-QAM on 242-, 484-, 996- and RUs" Revised. Agreed in principle. Deleted this sentence since it’s covered by bullet. TGax Editor to make changes as shown in under all headings that contain CID 7465. 9613 42 Remove the following: "Optional support for 1024-QAM on 242-, 484- and 996-tone RUs" Because it is a redundant sentence with the following: "Optional support for HE-MCSs 10 and 11" Remove the following sentence, "Optional support for 1024-QAM on 242-, 484- and 996-tone RUs" Agreed. Deleted the sentence. TGax Editor to make changes as shown in under all headings that contain CID 9613. 6071 43 Optional support for 1024-QAM on 242-, 484- and 996-tone RUs seems to be part of Optional support for HE-MCSs 10 and 11 Delete line 43 Agreed. Deleted the sentence. TGax Editor to make changes as shown in under all headings that contain CID 6071. 8364 43 The condition "Optional support for 1024-QAM on 242-, 484- and Rus" seems to be covered by the condition "Optional support for HE-MCSs 10 and 11". The reason is that HE-MCSs 10 and 11 is basically 1024-QAM modulation based on the table in 28.5. Replace the two sentences with "Optional support for Revised. Deleted the sentence.

between non-AP STA and AP STA. 7293 65 Chapter 4 provides a general description of the wireless system.. It should be written in a declarative but not normative language. Thus, "may" should not be appeared in the sentence. Replace "may be set" with "is allowed to set". Revised. Changed to “can” in the proposed text. TGax Editor to make changes as shown in under all headings that contain CID7293. 7703 65 This statement is not intended to be normative, but a declaration that the normative capability is specified later in the text Change "may" to "can" Agreed. Changed to “can” in the proposed text. TGax Editor to make changes as shown in under all headings that contain CID7703. 4713 These items whether are main or not is subjective at this point and maybe not correct. E.g., dynamic fragmentation level 0 is actually no fragmentation (highly a new MAC feature). As in comment. Revised. Dynamic fragmentation 0 is removed from the list since it is not a feature. TGax Editor to make changes as shown in under all headings that contain CID 4713. 9246 Optional support for UL-MU-MIMO should be mentioned here. Add such description in clause 4.3.14a. Agreed. “UL MU-MIMO” to the list. TGax Editor to make changes as shown in under all headings that contain CID 9246. TGax Editor: Please modify this section as follows: 4.13.4a High efficiency (HE) STA The IEEE 802.11 HE STA operates in frequency bands between 1 GHz and 6 GHz. In the 5 GHz band, the following apply: An HE AP is also a VHT AP An HE non-AP STA that supportsing 20 MHz, 40 MHz, 80 MHz, 160 MHz and 80+80 MHz is also a VHT non-AP STA except when the non-AP STA declares that it only supports 20 MHz channel bandwidth. It is mandatory for an HE non-AP STA to support operation in 20 MHz channel bandwidth
