Announcement frame followed after SIFS by an HE NDP followed after SIFS by a BRP Trigger frame followed after SIFS by a PPDU containing one or more HE Compressed Beamforming frames, or" specified in 9694 "-- a VHT NDP Announcement frame followed after SIFS by a VHT NDP followed after SIFS by a PPDU containing one or more VHT Compressed Beamforming frames..." The HE sounding procedure should be included. Insert the following: "-- an HE NDP Announcement frame followed after SIFS by an HE NDP optionally followed after SIFS by a PPDU containing one or more HE Compressed Beamforming And CQI frames or," As per comment. Revised- Agree in principle. Add the missing case of HE sounding. TGax editor makes changes as shown in the as specified in 4833 i) it is not what "the RU Allocation subfields of the MU-RTS frame for all intended receiver are equal to the BW subfield in the Common Info field of the MU-RTS frame" means. The two fields that are compared are encoded in quite different ways. ii) in the 'otherwise' case, the 'preceding PPDU' may be an MU-RTS, but the previous bullet that is supposed to describe the MU-RTS case does not cover all the MU-RTS cases, pointing to the 'otherwise', hence there is a loop and something missing. Make sure there is a defiend behavior for all the cases Revised- Agree on the first comment. Make a change for considering two different field encoding. But, regarding the second comment, ‘otherwise’ case is covering all things that do not meet the condition of the first bullet. TGax editor makes changes as shown in the as specified in 5775 If MU-RTS can be sent in HT PPDU or VHT PPDU format, describe how to set TXVECTOR parameter CH_BANDWIDTH Clarify Rejected- If a MU-RTS frame is transmitted in an HT PPDU or a VHT PPDU format, the below base rule is applied.
If there is no non-HT duplicate frame exchange in a TXOP, the TXOP holder shall set the TXVECTOR parameter CH_BANDWIDTH of a non-initial PPDU to be the same or narrower than the TXVECTOR parameter CH_BANDWIDTH of the preceding PPDU that it has transmitted in the same TXOP. 9600 "If there is no non-HT duplicate frame exchange in a TXOP, the TXOP holder shall set the TXVECTOR parameter CH_BANDWIDTH of a non-initial PPDU to be the same or narrower than the TXVECTOR parameter CH_BANDWIDTH of the preceding PPDU that it has transmitted in the same TXOP." When an HE AP transmits an HE DL MU PPDU with preamble puncture, the TXVECTOR parameter CH_BANDWIDTH selection rule should be seperately defined. Because the above current rule does not cover it. As per comment. Revised- Agree in principle. When an HE AP transmits multiple HE DL MU PPDUs with preamble puncture in a same TXOP, additional constraint for the RU allocation is needed. TGax editor makes changes as shown in the as specified in 5969 Please clarify can an HE MU PPDU contain a Trigger frame or UL MU Response scheduling HE Variant HT Control field to allocate resources for UL MU acknowledgements transmission. Please add clarification are Trigger frames or UL MU response scheduling fields to solicit UL BAs allowed in HE MU DL PPDUs when the TXOPLimit is 0. Revised- Agree in principle. Add the missing case of multiple HE trigger-based PPDU transmissions in a TXOP with the TXOP limit equal to 0. In consequence, multiple Trigger frames (or UL MU response scheduling A-Control fields) to solicit multiple UL BAs are allowed in HE DL MU PPDU when the TXOPLimit is 0.
TGax editor makes changes as shown in the as specified in 9861 Multiple HE trigger-based PPDU can be sent as long as all the PPDUs are sent as immediate response to same Trigger frame. Need further clarification As in the comment. Revised- Agree in principle. Add the missing case of multiple HE trigger-based PPDU transmissions in a TXOP with the TXOP limit equal to 0. TGax editor makes changes as shown in the as specified in 5968 It is unclear may there be just one Trigger frame or multiple trigger frames in a TXOP with TXOP Limit set to 0. Please change to:"5) A basic trigger variant Trigger frame." Revised- Agree in principle. Single Trigger frame is allowed in a TXOP with the TXOP limit equal to 0. TGax editor changes as shown in the as specified in 7670 Add HE sounding subclause As in comment Revised- Agree in principle. Add the missing reference for HE sounding sub-clause. TGax editor makes changes as shown in the as specified in 7881 Link adaptation is also described in 27.13 Add "and 27.13" after "10.31" Revised- Agree in principle. Add the missing reference for HE link adaptation sub-clause. TGax editor makes changes as shown in the as specified in 9346 Link adaptation through the HE variant HT Control field is specified in 27.13 and it should be also included. Add "and 27.13 (Link adaptation using the HE variant HT Control field)" at the end of item e). Revised- Agree in principle. Add the missing reference for HE link adaptation sub-clause.
