Re: [PATCH 2/2] Require WMM to be enabled before allowing inclusion of the QBSS Load element

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Jouni,

It is called the QBSS Load element in 802.11e-2005 and is called the
BSS Load element in 802.11-2012.

Calling it QBSS Load in the documentation more clearly distinguishes
that by spec this is for a QBSS only, that is, where WMM is enabled
only.

802.11e-2005 and 802.11-2012 specify that this element must only be
present for a QOS-enhanced BSS.

>From 802.11e-2005:

22
QBSS Load
The QBSS Load information element is only present within Beacon frames
generated by QAPs. The QBSS Load element is present when
dot11QosOptionImplemented and dot11QBSSLoadImplemented are both true.

23
EDCA Parameter Set
The EDCA Parameter Set information element is only present within
Beacon frames generated by QAPs. The EDCA Parameter Set element is
present when dot11QosOptionImplemented is true and the QoS Capability
element is not present.

24
QoS Capability
The QoS Capability information element is only present within Beacon
frames generated by QAPs. The QoS Capability element is present when
dot11QosOptionImplemented is true and EDCA Parameter Set element is
not present.

Thanks,

Nick
