This content of this panel depends whether OFDMA system is a victim or an interfering system.  If the OFDMA is an interferer, you will have to set the spectrum emission mask and the emissions floor. It is the same input as for CDMA, see Section ‎8.3.4.

  • In DL, the unwanted emission mask corresponds to the BS transmitting over all the RBs (i.e. the emission bandwidth is the same as the System Bandwidth input)
  • In UL, the emission bandwidth (i.e. in-band part of the unwanted emission mask) corresponds to the UE transmitting over a number of RBs (i.e. the emission bandwidth is equal to the RB bandwidth x Number of RBs requested per user) while the system bandwidth is equal to the total RBs x RB bandwidth. Note that the system bandwidth is input to SEAMCAT and approximately RB bandwidth x the total Number of RBs (i.e. Max. subcarriers per BS input).
