Re: [STDS-802-11-TGBE] BFRP discussion

HI Jinyoung,

 

I am also in general good with the description. Should we somehow indicate the exclusiveness? Say, something like (in blue),

 

An EHT beamformer that has initiated an EHT TB sounding sequence may send another more than one BFRP Trigger frame in the same TXOP, with any STA being triggered only once within the TXOP as shown in Figure 35-29 (An illustration of EHT TB sounding).

 

Thanks.

Regards,

srini

Hi Jinyoung,

 

Thank you for the revisions. I think the direction is good. Though it is not really clearly a normative behavior.

 

How about change the sentence into:

“ An EHT beamformer that has initiated an EHT TB sounding sequence shall transmit a BFRP trigger to solicit feedback and may send another more than one BFRP Trigger frame in the same TXOP.”

Hi,

 

Yesterday, I’ve presented 21/2013 (CRs for 35.5.3) and members want more discussion by email. So I make this email thread.

The addressed issue is that:

Currently, the same STA can’t be re-polled but the other STAs can be polled by additional BFRP Trigger in the same TXOP.

So the current figure has some problem.

So I’d like to remove the word ‘One or more sequences’ and make some changes the BFRP explanation as below.

BFRP Trigger frames sent within an EHT TB sounding sequence shall solicit EHT TB PPDUs. (move from other place)

An EHT beamformer that has initiated an EHT TB sounding sequence may send another more than one BFRP Trigger frame in the same TXOP as shown in Figure 35-29 (An illustration of EHT TB sounding).

 

Please give me your opinions or good directions for the CR.

 

Best regards,

Jinyoung
