The physical channels for transmitter tests shall be configured according to E-TM1.1 on all E-UTRA carriers and N-TM on all NB-IoT carriers.
For guard band transmitter tests, NB-IoT PRB is placed closest to E-UTRA PRBs in the E-UTRA carrier containing the NB-IoT PRB.
The power for E-UTRA PRB and NB-IoT PRB is set by following procedures:
– The average power per PRB over all PRBs (from both NB-IoT and the E-UTRA carrier containing the NB-IoT PRB) is calculated according to manufacturer’s declared rated output power (Prated,c);
Average power per PRB (Pavg) = Prated,c / (NRB + 1) [W]
– The power of boosted NB-IoT PRB (PNB-IoT) is calculated according to manufacturer’s declared rated NB-IoT maximum power dynamic range (X dB >= 6 dB)
Power per boosted NB-IoT PRB (PNB-IoT) = Pavg * 10(X/10) [W]
– The remaining power is allocated to E-UTRA PRBs.
Power per E-UTRA PRB = (Prated,c – PNB-IoT) / NRB [W]
