Hi Jay, all,

 

The motivation for the two modes is not to restrict particular type of traffic but rather related to channel access.

  1. If the AP knows that the traffic is only going to be to itself, then the AP can grab the medium anytime the STA does not transmit an expected frame. Now, the case where AP can know all traffic is going to be for itself is the “only UL traffic” case. Hence, we have Mode 1.
  2. If the AP does not know that the traffic is only going to be to itself, then the AP cannot grab the medium anytime the STA does not transmit an expected frame because it simply does not know for sure what the STA is doing at this time. This would occur when AP gives the STA the flexibility to transmit any type of traffic without controlling the STA’s priorities. Hence, we have Mode 2.

 

 

Regards,

Dibakar

Hi Dibakar,

 

I echo Yongho’s comments, the following rule shall be same for mode1 and mode2 that AP decides whether to regain the channel access or not.

 

 

·       The CS mechanism indicates that the medium is idle at the TxPIFS slot boundary after the end of either the transmission of the last immediate response frame sent to that STA or the reception of the last frame from that STA that did not require an immediate response.

 

Furthermore, according to following table, as mode1 is defined as UL only, it’s natural to define mode2 as P2P only. Therefore, it makes less sense to do overlap definition.

 

Table 9-31xxx TxOP Sharing Mode subfield encoding

 

TxOP Sharing Mode subfield value

MU-RTS that does not initiate MU-RTS TXOP Sharing procedure

1

MU-RTS that initiates MU-RTS TXOP Sharing procedure wherein a scheduled STA can only transmit PPDU addressed to its associated AP

2

MU-RTS that initiates MU-RTS TXOP Sharing procedure wherein a scheduled STA can transmit PPDU(s) addressed to its associated AP or addressed to another STA

3

Thanks
