B.7 Averaged EVM
38.1083GPPNRRelease 17Satellite Access Node radio transmission and receptionTS
EVM is averaged over all allocated downlink resource blocks with the considered modulation scheme in the frequency domain, and a minimum of slots where is the number of slots in a 10 ms measurement interval.
For FDD the averaging in the time domain equals the slot duration of the 10 ms measurement interval from the equalizer estimation step.
– Where Ni is the number of resource blocks with the considered modulation scheme in slot i.
– 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 
in the 
calculation.
– Thus we get:
Annex C (normative):
Characteristics of the interfering signals
The interfering signal shall be a PUSCH or PDSCH containing data and DM-RS symbols. Normal cyclic prefix is used. The data content shall be uncorrelated to the wanted signal and modulated according to clause 6 of TS 38.211 [9]. Mapping of PUSCH or PDSCH modulation to receiver requirement are specified in table C-1.
