E.9.1 EVM for PSSCH and PSCCH

The calculation of the EVM for PSSCH and PSCCH follows the procedure defined in Annex E.4. The EVM is calculated separately for PSSCH and PSCCH using separate equalizer, while the in-band emission is calculated only once.

The measurement period for EVM of PSSCH and PSCCH is 15 subframes. When V2X transmissions are shortened due to transmission gap of 1 symbol at the end of the subframe, the EVM measurement interval is reduced by one symbol, accordingly.

E.9.2 EVM for PSBCH

The calculation of the EVM for PSBCH follows the procedure defined in Annex E.4. The duration over which EVM is averaged shall be 24 subframes.
