The general EVM is averaged over basic EVM measurements for n slots in the time domain.

,

where n is

for PUCCH, PUSCH.

The EVM requirements shall be tested against the maximum of the RMS average at the window W extremities of the EVM measurements:

Thus is calculated using in the expressions above and is calculated using .

Thus we get:

The calculation of the EVM for the demodulation reference signal, , follows the same procedure as calculating the general EVM, with the exception that the modulation symbol set defined in clause F.2 is restricted to symbols containing uplink demodulation reference signals.

The basic measurements are first averaged over n slots in the time domain to obtain an intermediate average .

In the determination of each , the timing is set to if , and it is set to otherwise, where and are the general average EVM values calculated in the same n slots over which the intermediate average is calculated. Note that in some cases, the general average EVM may be calculated only for the purpose of timing selection for the demodulation reference signal EVM.

Then the results are further averaged to get the EVM for the demodulation reference signal, ,

The PRACH EVM, , is averaged over 2 preamble sequence measurements for long preamble formats as defined in table 6.3.3.1-1 in [9] and averaged over 10 preamble sequence measurements for short preamble formats as defined in table 6.3.3.1-2 in [9]..

The EVM requirements shall be tested against the maximum of the RMS average at the window W extremities of the EVM measurements:

Thus is calculated using and is calculated using .

Thus we get:
