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 in-band transmitter tests, one E-UTRA PRB is punctured and replaced by NB-IoT PRB which also contains certain REs for the hosting E-UTRA carrier.
The power for E-UTRA RE and NB-IoT RE are set by following procedures:
– The average power per RE 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 RE (Pavg) = Prated,c / (NRB * ) [W]
– The power per boosted NB-IoT RE (PNB-IoT) is calculated according to manufacturer’s declared rated NB-IoT maximum power dynamic range (X dB >= 6 dB), with the power boosting only applies on the NNB_IoT REs containing NB-IoT signal.
Power per boosted NB-IoT RE (PNB-IoT) = Pavg * 10(X/10) [W]
– The remaining power is allocated to NE-UTRA E-UTRA REs.
Power per E-UTRA RE = (Prated,c – PNB-IoT * NNB_IoT) / NE-UTRA [W]
