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.

Furthermore, the device’s clock frequency typically does not match the
clock frequency of the synchronized sensors, and so the device should transmit on the same channel multiple
widely spaced times in order for the sensors to estimate the device’s clock frequency relative to themselves
and to be able to suitably scale the device’s advertised times of departure.

Proposed Change
164
“shall be capable of” is not clear. It might allow a device to be capable of doing something, but not actually do it
Change to “shall” in each case. Ditto “shall be able to”
AdHoc Notes:
GEN: 2021-10-01 15:33:36Z – status set to: Submission Required
GEN: 2021-05-12 22:27:19Z – status set to: Submission RequiredDiscussion:
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?
