corresponding fixed subscriber station, must be directed to
each other and therefore are considered assigned.
In contrast to appellant's view that there is no teaching
and suggestion in Wang of a database of measured co-channel
interference characteristics, we respectively disagree. The
examiner properly relies on the preferred channel list (PCL)
of Wang as a basis from which to allocate communication
channels, which are specifically ranked in accordance with the
occurrence of prior events on the channels, or a channel
history, which is in-part based upon the mean quality margin
and current channel quality determinations. The discussion at
column 1, lines 36-45 of Wang relied upon by the examiner
indicates that the co-channel interference of the type
discussed in Hamabe is also used as a measure of quality as
discussed in this reference. Dynamic channel allocation
methods are also taught in Wang to complement those in Hamabe
to minimize or eliminate this co-channel interference.
In addition to the preferred channel list comprising a
database of Wang comparable to the claimed database of claim 1
for example, Hamabe utilizes a list of candidate channels
