5039 21 The text "An HE non-AP STA shall support operation in 20 MHz channel bandwidth only" seems to imply that 40 MHz and wider bandwidths are not allowed. I assume that 20 MHz is mandatory but bandwiths are optional. Suggest using this language (or similar) instead. Revised. TGax Editor to make changes as in all headings that contain CID 5039. 5117 21 Regarding, "An HE non-AP STA shall 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 all headings that contain CID 5117. 6928 21 The phrase: "An HE non-AP STA shall 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 shall 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 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.
