Re: [STDS-802-11-TGBN] NPCA straw polls

["yuxin.lu" <eeluyx@xxxxxxxxx>]

Hi Yuki,

Thanks for preparing those SPs, for SP3, below are some comments for your consideration 

Would you clarify whether this NPCA STA includes both AP and non-AP?  

. if it includes AP, we have an agreement (Motion #134) that says that [An AP shall not allow the use of NPCA within its BSS if the BSS operating bandwidth is less than or equal to TBD MHz, where TBD = 40 MHz or 80 MHz]

. if it includes non-AP, non-AP can simply indicate its NPCA Supported BW with other operation parameters to clarify its NPCA operating capability to AP, instead of performing disabling NPCA which introduces additional signaling overhead; for example, if non-AP indicates NPCA Supported BW=80 MHz, then its operating channel width is changed from 80MHz to 40MHz (should notify this change to AP via OMI/OMN), non-AP automatically disables NPCA since it can no longer support 80MHz, or it can update its NPCA operating capability to AP with a new NPCA Supported BW value 

Best Regards

Yuxin

Hi Alfred,

Could you please schedule time to consider the following straw polls?
Comments, questions and suggestions are welcome!

SP1:
Do you agree to include the following into the 11bn SFD?
* An NPCA STA may dynamically indicate a mode of NPCA indicating whether NPCA operation is enabled or disabled Detailed signaling is TBD

SP2:
Do you agree to include the following into the 11bn SFD?
* An AP shall indicate in the capability that the NPCA operation is not supported when the operating band of an AP is 2.4GHz band

SP3:
Do you agree to include the following into the 11bn SFD?
* An NPCA STA shall indicate in the NPCA mode that NPCA operation is disabled when the operating channel width of the NPCA STA is changed from channel width more than TBD MHz to equal or less than TBD MHz

SP4:
Do you agree to include the following into the 11bn SFD?
* An NPCA AP shall not transmit TBD frames when operating in the NPCA primary channel

SP5:
Do you agree to include the following into the 11bn SFD?
* An NPCA AP shall only respond to a frame in the NPCA primary channel received from a NPCA STA that is associated to the NPCA AP.

SP6:
Do you agree to include the following into the 11bn SFD?
* An NPCA STA shall only respond to a frame in the NPCA primary channel received from another NPCA STA which is the destination of ICF or the source of ICF.


Thanks,
Yuki
