C.0 Downlink signal levels
38.521-43GPPNRPart 4: PerformanceRadio transmission and receptionRelease 17TSUser Equipment (UE) conformance specification
Downlink power settings to be configured for connection setup has been defined in this clause covering both FR1 and FR2.
C.0.1 FR1 Downlink Signal Levels (Conducted)
The downlink power settings in Table C.0.1-1 is used for FR1 conducted unless otherwise specified in a test case.
If the UE has more than one Rx antenna, the downlink signal is applied to each one. All UE Rx antennas shall be connected.

NOTE 1: The channel bandwidth powers are informative, based on -85dBm/15kHz 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 each UE Rx antenna. NOTE 3: DL level is applied for any of the Subcarrier Spacing configuration ( ) with the same power spectrum density of -85 dBm/15 kHz. |

The default signal level uncertainty is [+/-3] dB at each test port, 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]
C.0.2 FR2 Downlink Signal Levels (Radiated)
The downlink power settings in Table C.0.2-1 is used unless otherwise specified in a test case.

NOTE 1: The channel bandwidth powers are informative, based on [-99] dBm/60 kHz 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 ( |
