Reduce interference by time or

frequency division

Cell center using more bandwidthresource, the cell edge using 1/3

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
