"A subchannel can be said to experience flat fading when it's bandwidth
is small compared to the coherence bandwidth of the channel"

What is coherence bandwidth?

Thx in advance...

Coherence bandwidth is appoximately inverse of rms delay spread of
mutipath channel. Conceptually it can be thought as,
the bandwidth overwhich delay power spectrum or mutipath intensity
profile is non-zero.

Since your bandwidth of interest is less than coherencebandwidth it is
flat i.e not a frequncy selective fading which causes ISI.
