Re: [STDS-802-11-TGBN] DSO PDT and CR doc 11-25/1164

Hi Morteza,

 

Echo with Yuxin, I think the DSO ICF should be transmitted in a pre-UHR PPDU, thus the pre-UHR STAs can be scheduled in the primary subband while the DSO STAs can be scheduled in the DSO subband in the same time.

It is not efficient to make the a TXOP to be DSO dedicated.

 

Best Regards

Hi Morteza,

 

Thanks for explaining. However, I'm not sure if the DSO ICF has to be carried in a UHR PPDU? I was not able to find the supporting words. 

If carried in a pre-UHR PPDU, the pre-UHR STAs can decode and be scheduled conventionally. In case there are only few DSO STAs in a BSS, it would be a waste to dedicate a DSO TXOP. Please clarify. Thanks

Hi Yuxin,

 

Pre-UHR STAs can’t be scheduled with the DSO STAs because pre-UHR STAs can’t receive UHR PPDU. But non-DSO UHR STAs can be scheduled with the DSO STAs.

Per-UHR STAs can still be scheduled on the non DSO TXOPs.

 

Thanks,

Morteza

Hi Morteza,

 

I see the following statement. Does it mean pre-UHR STAs are excluded from the current schedule? I expect that they can be scheduled within their corresponding operating bw by the AP together with the DSO STAs via the DSO ICF. Could you clarify? Thanks 

" The DSO ICF-ICR exchange and the PPDUs following it, shall only be transmitted between UHR STAs"
