DESCRIPTION
"This is a capability variable.
Its value is determined by device capabilities.
This attribute is a bitmap that indicates the preamble prunctured
channeling support,
where bit
equal to
0 is set to 1 to indicate support for the reception of
an 80 MHz preamble where the secondary 20 MHz
subchannel is punctured,
bit
equal to
1 is set to 1 to indicate support for the reception of an 80 MHz preamble where
one of the two 20 MHz subchannels in the secondary 40 MHz channel is punctured,
bit
equal to
2 is set to 1 to indicate support for the reception of
a 160 MHz or 80+80 MHz preamble where
in the pri-
mary 80 MHz of the preamble only
the secondary 20 MHz channel is punctured, and
bit
equal to
3 is set to 1 to indicate support for the reception of
a 160 MHz or 80+80 MHz preamble where
one or both of the 20 MHz subchannels in the secondary 40 MHz channel are punctured.
in the primary 80 MHz of the preamble, the primary 40 MHz is present."
