Appellants argue that Watanabe does not teach "receiving
channel status information indicating an error profile of the
communication channel," as recited in claim 1 (Br3-4; RBr2).
A section 103 analysis begins with a key legal question:

profiles have parameters of Doppler Frequency (Hz), Average BER
(Bit-Error Rate), and Average Burst Length (Bits). Thus, the
"error profile" can be defined as the characterization (profile)
of the type and magnitude of channel error statistics, which is
