The downlink power settings in Table C.0-1 is used unless otherwise specified in a test case.

SCS (kHz)		Unit	Channel Bandwidth
SCS (kHz)		Unit	50 MHz	100 MHz	200 MHz	400 MHz
60	Number of RBs		66	132	264	N/A
60	Channel BW power	dBm	-70	-67	-64	N/A
120	Number of RBs		32	66	132	264
120	Channel BW power	dBm	-70	-67	-64	-61
	SS/PBCH SSS EPRE	dBm/SCS	-99 for DL SCS= 60 kHz -96 for DL SCS = 120 kHz	-99 for DL SCS = 60 kHz -96 for DL SCS = 120 kHz	-99 for DL SCS = 60 kHz -96 for DL SCS = 120 kHz	-99 for DL SCS = 60 kHz -96 for DL SCS = 120 kHz
Note 1: The channel bandwidth powers are informative, based on [-99]dBm/60kHz SS/PBCH SSS EPRE, then scaled according to the number of RBs and rounded to the nearest integer dBm value. Full RE allocation with no boost or deboost is assumed. Note 2: The power level is specified at the centre of quiet zone. Note 3: DL level is applied for any of the Subcarrier Spacing configuration () with the same power spectrum density of [–99]dBm/60kHz.

The default downlink signal level uncertainty is +/- TBD dB, for any level specified. If the uncertainty value is critical for the test purpose, a tighter uncertainty is specified for the related test case in Annex F.

For TRP measurement, DL signal may be supplied from RSRP based pathloss compensation link. Downlink signal level using RSRP based pathloss compensation link is specified in Table C.0-2 or Table C.0-3.
