Delete "or as many as 9....epending on the channel bandwidth
TBD)"
[Reason for Edit]
Minimum is known in most cases (assuming a 100 MHz UNII-band and
20 MHz channelization) but maximum is difficult to determine.

insert after "quality of all" text "or a set of"
[Reason for Edit]
Since originator might already know that some channels are occupied
not all channels must be measured.

Insert "6) Measurement Bandwidth"
[Reason for Edit]
20, 10 and optiol 5 MHz channels are supported, thus the measurement
bandwidth should be defined (especially if it differs from the one
in use)

Replace whole section with:
"The anticipated power control on a link at 5.25-5.35 and 5.725-
5.825 GHz will span a dynamic range of at least 45 dB. This gain variation
is what can be expected between a BS antenna and a SS that is
located anywhere from 50 to 2000 meters from the BS. Note that
the 45 dB dynamic range applies to both BS and SS.
The power is defined as the EIRP at the antenna.
Step size of power control range will be 3 dB and the power level
shall provide monotonic transmission power.
Power control steps are set in the following manner:
Maximum allowed - N * 3 dB, where N ={0,1,2...15)
True EIRP = Maximum allowed + Antenna correction, where the directive
antenna correction is the additional power obtained by the antenna gain
With FCC ruling on U-NII middle and upper bands Antenna correction
would become:
0 dB directive antenna gain <= 0 dBi
1 dB directive antenna gain = 1 dBi
2 dB directive antenna gain = 2 dBi
3 dB directive antenna gain = 3 dBi
4 dB directive antenna gain = 4 dBi
5 dB directive antenna gain = 5 dBi
6 dB directive antenna gain >= 6 dBi
For example, maximum allowed power on U-NII-bands are
20 MHz 10 MHz 5 MHz
U-NII middle 23 dBm 20 dBm 17 dBm
U-NII upper 29 dBm 26 dBm 23 dBm
Thus a system operating in the upper U-NII band with 10 MHz
channels utilizing 14 dBi antennas would have the following
EIRP power control steps:
32 29 26 23 ... -13
One signed byte is reserved for the EIRP power with 1 dBm
resolution. This is enough for future needs too.
[Reason for Edit]
The true EIRP value is the one that counts. If a relative
value is used, then the receiver should know the transmitter's
antenna gain to be able to calculate the path loss, which is
one of the main parameters in defining the right transmit
power as well as in link adaptation.
