consistent with the discussions we found on the Internet. 2 Thus,
the claimed "channel status information indicating an error
profile of the communication channel" would be one of the three
error profiles, Error 1, Error 2, or Error 3. An "error profile"
must be something different than just an "error" or the word
"profile" would be given no effect. "All words in a claim must
be considered in judging the patentability of that claim against
the prior art." In re Wilson, 424 F.2d 1382, 1385, 165 USPQ 494,
496 (CCPA 1970).
The examiner does not interpret or discuss the meaning of
"error profile." The examiner finds that Watanabe discloses
detecting an error on the decoding side in the error check
circuit 125 of Fig. 2, which causes output of a retransmission

The error profiles of wireless systems generally differ from
wired systems in that the errors are very likely to come in
bursts. For example, when a single signal splits and
follows two or more paths to the other node, arriving at
different times (known as multipathing), out-of-order packet
and multiple-packet errors can result. Another effect,
fading, can produce long gaps in information streams, and
Doppler shifts can disrupt timing and sequencing. In fact,
recent research indicates that even stationary wireless
systems in metropolitan areas experience Doppler shifts
because of the movement of objects in their vicinity. In
addition, long distances between nodes in wireless systems-
such as in direct satellite systems-are subject to echoing
errors and special problems with gaps in information
streams. Furthermore, all these types of errors can occur
in combination.
