Re: [STDS-802-11] ANA request

Yes, BCE is specific to S1G.

RSN bit 12 was allocated to "Protected Block Ack Capable" until the first LB on 802.11REVme.  It was changed to be bit 12 in the RSNXE due to this comment:

"Based on discussion with several members (affiliated with different organizations), it was discovered that many devices (already deployed in the field) are incorrectly setting the PBAC bit in RSN Capabilities field to 1 even when they do not support protected BA operation. Future amendments are expects to mandate support for protected BA procedure (given the increasing vulnerabilities). Incorrect setting of PBAC bit will create inter-op issues when the peer device that supports protected BA procedure, expects the other side to follow the same procedure."

It seems unlikely to me that there are S1G devices that had the same implementation bug, but Dave H. or Dave G. might know for sure.

Great.

I see it is S1G and so might not have any backward compatibility issues.

Hello Robert,

Thank you for pointing this out.

I am including Henry and Jouni here in case they have any concerns on using Bit 12. @Henry Ptasinski @Jouni Malinen

Please note using Bit 12 for “BIP Compact Encapsulation” was proposed in doc 23/1777r7 (Henry’s submission).

 

Regards,

Emily

Hello Emily,

 

Allocated as requested – Bit 12 of RSN Capability is now "BIP Compact Encapsulation". 

 

This field was "reserved previously allocated". Before it became reserved it was "Protected Block Ack Capable (PBAC)" allocated to TGmb. I'm assuming the group is making this allocation with knowledge of its history and potential use in prior implementations.

 

Regards,

-Robert
