Hello Jon, We already fixed the "shall be capable
of"s under CID 546.
What we discussed yesterday was the "shall be able
to"s. And as for CID 546 I think "shall support" is the best term if it's really something that needs to be supported rather than actually done at that point (which should be just "shall").
So I suggest: 9.1 A STA shall be able to properly construct a subset of the frames specified in this clause for transmission and to decode a (potentially different) subset of the frames specified in this clause upon validation following reception. The particular subset of these frames that a STA constructs and decodes is determined by the functions supported by that particular STA. A STA shall validate every received frame using the frame check sequence (FCS) and interpret certain fields from the MAC headers of all frames. -> A STA shall properly construct a subset of the frames specified in this clause for transmission and decode a (potentially different) subset of the frames specified in this clause upon validation following reception.

In this case, the mesh STA shall set the Accept Reservations subfield in the Flags field to 1 in the MCCAOP Advertisement Overview elements it transmits. -> A mesh STA with dot11MCCAActivated equal to true shall support tracking dot11MCCATrackStatesActive MCCAOP reservations, including its own reservations.

In this case, the mesh STA shall set the Accept Reservations subfield in the Flags field to 1 in the MCCAOP Advertisement Overview elements it transmits. 10.30.2.2 During a PSMP sequence, a STA shall be able to receive frames during its scheduled PSMP-DTT and is not required to be able to receive frames at other times. -> During a PSMP sequence, a STA shall support receiving frames during its scheduled PSMP-DTT; it is not required to support receiving frames at other times. 10.46.1 An S1G STA that is starting a BSS shall be able to receive and transmit at each of the <S1G-MCS, NSS> tuple values indicated by the Basic S1G-MCS and NSS Set field of the S1G Operation parameter of the MLME-START.request primitive and shall be able to receive at each of the <S1G-MCS, NSS> tuple values indicated by the Supported S1G-MCS and NSS Set field of the S1G Capabilities parameter of the MLME- START.request primitive. -> An S1G STA that is starting a BSS shall support receiving and transmitting at each of the <S1G-MCS, NSS> tuple values indicated by the Basic S1G-MCS and NSS Set field of the S1G Operation parameter of the MLME-START.request primitive and shall support receiving at each of the <S1G-MCS, NSS> tuple values indicated by the Supported S1G-MCS and NSS Set field of the S1G Capabilities parameter of the MLME- START.request primitive. 10.53.4 A Sectorized beam capable AP supporting TXOP-based

AdHoc Notes: GEN: 2021-10-01 15:33:36Z – status set to: Submission Required Discussion: 28 Instances of “shall be capable of” The first instance at P1745.5 “A STA
shall be capable of receiving MPDUs, containing all or part of an MSDU, of arbitrary length that is less than or equal to the maximum MSDU size as defined in 9.2.4.7 (Frame Body field), plus any security encapsulation
overhead, plus MAC header and FCS. Changing as requested: A STA
shall receive MPDUs, containing all or part of an MSDU, of arbitrary length that is less than or equal to the maximum MSDU size as defined in 9.2.4.7 (Frame Body field), plus any security encapsulation overhead, plus MAC
header and FCS. Does not read correctly. This is similar to the other 27 instances. Proposed Resolution: Reject: The change of “shall be capable of” to “shall” does not provide a complete sentence. While making a more extensive change to the sentence to some other form may be done,
the sentence is not wrong or ambiguous. Input? Jon ----------------------------------------------------------------------------- Jon Rosdahl Engineer, Senior Staff
