* First Zone Scheme is being determined by the FFR mode. Reuse 3 (FFR mode = ffrDlMap) is applicable
only for BS bandwidth of 10 MHz.
For First Zone Maximum Size the values are:
 If First Zone Minimum Size is set to No Limitations, the value range for Maximum Size is the same as
for Minimum Size.
 Else, the value range is No Limitations or First Zone Minimum Size+2N, up to a maximum of Y as
defined below.
The value of Y (which is actually the number of slots available for DL data) that sets the upper limit for
the Minimum and Maximum Size parameters depends on the Maximum Cell Radius and Total Uplink
Duration parameters, using the following formula:
Y=A-3*(Total Uplink Duration)-(Extra TTG),
where A=46 for BW of 5 or 10 MHz, and 32 for BW of 7 MHz.
