Note: Wanted and interfering signal are placed adjacently around Frequency of the carrier centre frequency
(Fc), where the Fc is defined for BS channel bandwidth of the wanted signal according to the table 5.4.2.2-1. The
aggregated wanted and interferer signal must be centered in the BS channel bandwidth of the wanted signal.
