Re: [STDS-802-11-TGBE] TXOP bandwidth signaling (1281r2)

Hell Kaiying,

Thanks!   Based on your comment, may I know if the following is the only sentence you would like to add to subclause 9.3.1.8,1?

In a BlockAck frame transmitted by an EHT STA in a non-HT duplicate format with bandwidth greater than 160/80+80 MHz, the TBD field carries the TXVECTOR parameter EXTENDED_CH_BANDWIDTH_IN_NON_HT and the TA field value is a bandwidth signalling TA. 

Regards,
Edward

Hi Edward,

 

Thanks for your comments.

 

As Alfred mentioned during the call, HT-delayed block ack is deprecated. So I don’t think I need to add anything for 9.3.1.8.1 BA frame format.

Actually REVmd draft 4.0 should remove the second sentence.

 “In a BlockAck frame transmitted in the context of (#4439)non-HT duplicate format and where the scrambling sequence carries the TXVECTOR parameter CH_BANDWIDTH_IN_NON_HT, the TA field value is a bandwidth signaling TA(#4439).”

 

Best regards,

Kaiying

Hello Kaiying,

 

In 20/1281r2, one of your instruction to the editor is to modify the following subclause 9.3.1.8.1 (based on IEEE 802.11ax Draft 7.0):

 

The TA field value is the address of the STA transmitting the BlockAck frame or a bandwidth signaling TA in the context of HT-delayed block ack. In a BlockAck frame transmitted in the context of HT-delayed block ack by a VHT STA or an HE STA or an EHT STA in a non-HT or non-HT duplicate format and where the scrambling sequence carries the TXVECTOR parameter CH_BANDWIDTH_IN_NON_HT, the TA field value is a bandwidth signaling TA. In a BlockAck frame transmitted by an EHT STA in a non-HT duplicate format with bandwidth greater than 160/80+80 MHz, the TBD field carries the TXVECTOR parameter EXTENDED_CH_BANDWIDTH_IN_NON_HT and the TA field value is a bandwidth signalling TA.

 

In REVmd Draft 4.0, however, the above-mentioned paragraph is shortened that no VHT STA and non-HT format are mentioned - see below:

 

The TA field value is the address of the STA transmitting the BlockAck frame(#4439)(#1512). In a BlockAck frame transmitted in the context of (#4439)non-HT duplicate format and where the scrambling sequence carries the TXVECTOR parameter CH_BANDWIDTH_IN_NON_HT, the TA field value is a bandwidth signaling TA(#4439).

 

Do you think you still need to modify 9.3.1.8.1 because of the recent update in REVmd Draft 4.0?

Thanks and Regards,
Edward

Hi Alfred, Liwen and Jeongki,

 

Since I forgot to mention that “MLO-Multi-link group addressed data delivery” is in R1 during last joint call, could you please add the following SP to the MAC queue?

 

SP: Do you support to change the spec text R1/R2 status of the three items under “MLO-Multi-link group addressed data delivery” to “R1”?

 

Thanks,

Kaiying
