C.0 Downlink signal levels
36.521-13GPPEvolved Universal Terrestrial Radio Access (E-UTRA)Part 1: Conformance testingRadio transmission and receptionRelease 17TSUser Equipment (UE) conformance specification
The downlink power settings in Table C.0-1 or Table C.0-2 are used 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.
If the UE has one Rx antenna, the downlink signal is applied to it.

Note 1: The channel bandwidth powers and RB allocations are informative, based on -85dBm/15kHz RS_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 in this calculation, but allocation may vary during setup. Note 2: The power level is specified at each UE Rx antenna. |

Note 1: The channel bandwidth power is informative, based on -85dBm/15kHz NRS_EPRE, then scaled according to the number of subcarriers and rounded to the nearest integer dBm value. Full RE allocation with no boost or deboost is assumed in this calculation, but allocation may vary during setup. Note 2: The power level is specified at the UE Rx antenna |

The default signal level uncertainty is +/-3dB 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.
