Re: [STDS-802-11-TGBN] TGbn queue request for L4S SP and PDT

[Binita Gupta <bingupta.ieee@xxxxxxxxx>]

Hi All,

I have uploaded a PDT for L4S (25/880r0) based on the SP above.

Please let me know if you have any feedback.

Hi Alfred,

Could you please add the following L4S SP to the TGbn MAC queue?  

Also, I received an offline request for this SP to be scheduled for a PM slot, so could you schedule this for one of the PM slots please.

L4S SP:

•       Do you agree to define in 11bn an optional mechanism for L4S support on the AP as below?

–       Define an MLME primitive that provides congestion notification from the MAC layer to the higher layer at the AP, to enable the upper layer to mark ECN bits on subsequent DL packets for L4S congestion signaling.

–       Enhance the MA-UNITDATA.request primitive to provide an indication whether the MSDU carries the packet of L4S flow

            NOTE - The conditions and criteria based on which the MAC layer determines to signal L4S congestion experienced notification to the upper layer is implementation specific and is outside the scope of this specification.

Also, could you please add the L4S PDT that is based on this SP + is addressing L4S related CIDs to the MAC queue.

• 11-25/880  -   PDT MAC on L4S 

Thanks,

Binita
