Reduce interference by time or
frequency division
Cell center using more bandwidthresource, the cell edge using 1/3
bandwidth
FFR is based mainly on time division;
while SFR is based on frequency division
With FFR, the cell center will be using
all sub-carriers; SFR only allow the use
of about 2/3 bandwidth at cell center FFR sub channel generally fixed at 1/3
of overall bandwidth ; SFR is adjustable
at or around 1/3 BW by using dynamic

When ICIC ON and OFF
ICIC reduce the center

cell edge user's SINR and
enhance the probability of
