Hi Binita,

According to the offline discussion, Brian has provided a good suggestion as below:

for the dynamically operational capability, the dot11XXXactivated should be used as the guidline required.

For the feature support field in the UHR MAC capabilities information field, set to 1 if dot11XXXactivated present and set to 0 if dot11XXXactivated not present

Let's take DBE as an example:

If dot11DBEOptionActivated is not present, it indicates the STA implementation is not capable of supporting DBE operation

If dot11DBEOptionActivated is true, it indicates enabled

If dot11DBEOptionActivated is false, it indicates disabled

In general, we should follow MIB guidline and make some changes to the encoding column corresponding to the XXX support filed in the UHR MAC capabilities information field

Best Regards！

Subject: Re: [STDS-802-11-TGBN] initial discussion on MIB

Hi Yan,

Thanks for starting this email.

All of the fields in the Table above (DSO Support, P-EDCA Support, DBE Support etc) are all referring to whether corresponding capability is supported. These are independent of whether the feature can be enabled or disabled. In that table only DBE and P-EDCA can be enabled/disabled by the AP whereas DSO and LLI can't be enabled/disabled by the AP

So, the MIB variable dot11XXXOptionActivated in all these cases are referring to capability support. If the MIB guideline is to use 'dot11XXXImplemented' to refer to capability, then one simple fix is to change all the MIB variables that are used for setting XXXSupport field to dot11XXXImplemented (if using dot11XXXOptionActivated), then there will not be any deviation from MIB guidelines. I am personally good with that change for DBE, if we make that consistently across all the UHR modes.

For the features that can be enabled/disabled (say DBE and P-EDCA above) there are no MIB variables defined to indicate enablement or disablement state, and we don't need separate MIB variables for that. The enablement or disablement state is indicated by XXXEnabled in the UHR Operation element.

Hope this helps to clarify and make progress on this topic.

Thanks,

Binita

Hi,
    Sorry for missing discussion of MIB on the joint meeting yesterday.
    For the dot11XXXactivated and dot11XXXimplemented, i'd like to initiate the discussion as below:

According to MIB guideline in 15/355r13 and 18/52r2, the 'dot11XXXImplemented' and 'dot11XXXActivated' refers to static implementation capability and dynamically operational capability,respectively. So my understanding is that if a certain feature does not support enablement/disablement, the relevant MIB should be 'dot11XXXImplemented', otherwise the corresponding MIB should be 'dot11XXXActivated'.
    However, i have a question on the the UHR MAC capabilities. Let's take the DBE support as an example:
        As DBE supports enablement/disablement, the dot11DBEOptionActivated should indicate if the DBE is enabled or disabled. But DBE support field in UHR MAC capabilities seems like to signal whether the DBE feature is supported or not(as DBE may be an optional feature)
        When DBE is not supported at all, how to set DBE support field based on the dot11DBEOptionActivated, since this MIB setting to false only refers to disablement

    In general, the 'dot11XXXImplemented' refers to capability and 'dot11XXXActivated' refers to enablement/disablement. we can not define both of these MIBs for a certain feaure. So when we don't support a feature(i.e., can enable/disable) at all, how to set XXXsupport field ?
    Please correct me if any misunderstanding and welcome to any further discussion

Best Regards！
