Apparatus, and an associated method, for generating a message summary
field. The message summary field indicates whether 802.11-formatted data
packets are communicated upon a frequency range to which a mobile station
operable in an IEEE 802.11 radio communication system is tuned. An
indicator indicates whether an 802.11 data packet is detected. And, a
reporter generates a measurement summary which includes a measurement
summary field populated with a value indicating the determination.
Subsequent analysis of the value of the field of the measurement summary
is utilized pursuant to dynamic frequency selection operations.
