This is the follow-up to the teleconf discussion
just now, toattempt to reach consensus on which puncturing
patterns are and
are not allowed.
STRAWMAN PROPOSAL:
If
the primary 20 MHz channel is the leftmost one, and x means
punctured,
- means not punctured and ? means can be punctured,
then
these correspond to only allowing the following patterns
in
each case (obviously the patterns will get rearranged if the
P20
is not the leftmost one) for the value of the Bandwidth
field
in the HE-SIG-A field of an HE MU PPDU:
4)
-x--
5)
--x- or ---x
6)
-x--???? but not -x--xxxx
7)
--x-???? but not --x-xxxx, or
---x???? but not ---xxxxx, or
--xx???? but not --xxxxxx
During the teleconf I think I heard some variants
proposed (calling
the one above z):
a) Allow full puncturing of S80, i.e.:
4)
-x--
5)
--x- or ---x
6)
-x--???? including -x--xxxx
7)
--x-???? including --x-xxxx, or
---x???? including ---xxxxx, or
--xx???? including --xxxxxx
b) Don't allow any puncturing of S80 (maybe the
D1.0 wording?), i.e.:
4)
-x--
5)
--x- or ---x
6)
-x------
7)
--x----- or
---x---- or
--xx----
c) Allow "any 2" puncturing for the 7
case (I think I heard something
like that?), i.e.:
4)
-x--
5)
--x- or ---x
6)
-x--???? [all x for ? TBD]
7)
--x-???? where exactly one of the ?s is a x, or
---x???? where exactly one of the ?s is a x,
or
----???? where exactly two of the ?s are an
x, or
--xx----
d) Or was it "at least 2" puncturing
for the 7 case, i.e.:
4)
-x--
5)
--x- or ---x
6)
-x--???? [all x for ? TBD]
7)
--x-???? where between 1 and 3 (4 TBD) of the ?s are xs, or
---x???? where between 1 and 3 (4 TBD) of
the ?s are xs, or
----???? where between 2 and 3 (4 TBD) of
the ?s are xs, or
--xx???? where between 0 and 3 (4 TBD) of
the ?s are xs
Plus a variant to any of the above:
e) For any/all of the above, don't allow more
than 2 adjacent xs
for the 160M case (obviously N/A for 80 and I
think also for 80+80)
Please select your option (z or a-d, plus e) or
otherwise describe
your understanding.
Happy Easter, and best wishes to you, your
colleagues and your families,
