6.5.2 Transmit modulation quality
Transmit modulation quality defines the modulation quality for expected in-channel RF transmissions from the UE. The transmit modulation quality is specified in terms of:
– Error Vector Magnitude (EVM) for the allocated resource blocks (RBs)
– EVM equalizer spectrum flatness derived from the equalizer coefficients generated by the EVM measurement process
– Carrier leakage
– In-band emissions for the non-allocated RB
All the parameters defined in subclause 6.5.2 are defined using the measurement methodology specified in Annex F.
6.5.2.1 Error Vector Magnitude
The Error Vector Magnitude is a measure of the difference between the reference waveform and the measured waveform. This difference is called the error vector. Before calculating the EVM the measured waveform is corrected by the sample timing offset and RF frequency offset. Then the carrier leakage shall be removed from the measured waveform before calculating the EVM.
The measured waveform is further modified by selecting the absolute phase and absolute amplitude of the Tx chain. The EVM result is defined after the front-end IDFT as the square root of the ratio of the mean error vector power to the mean reference power expressed as a %.
The basic EVM measurement interval in the time domain is one preamble sequence for the PRACH, and as specified in Table 6.5.2.1-1 for the PUCCH and PUSCH in the time domain. When the PUSCH or PUCCH transmission slot or subslot is shortened due to multiplexing with SRS, the EVM measurement interval is reduced by one symbol, accordingly. Likewise, when the PUSCH starting position is modified or when second last symbol is the ending symbol of the PUSCH subframe for Frame Structure Type 3, the EVM measurement interval is reduced accordingly. The PUSCH or PUCCH EVM measurement interval is also reduced when the mean power, modulation or allocation between slots or subslots is expected to change. In the case of PUSCH transmission, the measurement interval is reduced by a time interval equal to the sum of 5 μs and the applicable exclusion period defined in subclause 6.3.4, adjacent to the boundary where the power change is expected to occur. The PUSCH exclusion period is applied to the signal obtained after the front-end IDFT. In the case of PUCCH transmission with power change, the PUCCH EVM measurement interval is reduced by one symbol adjacent to the boundary where the power change is expected to occur.

For EVM evaluation purposes, [all PRACH preamble formats 0-4 and] all PUCCH formats 1, 1a, 1b, 2, 2a and 2b are considered to have the same EVM requirement as QPSK modulated.

6.5.2.2 Carrier leakage
Carrier leakage is an additive sinusoid waveform that has the same frequency as a modulated waveform carrier frequency. The measurement interval is one slot in the time domain.
6.5.2.2.1 Minimum requirements
The relative carrier leakage power is a power ratio of the additive sinusoid waveform and the modulated waveform. The relative carrier leakage power shall not exceed the values specified in Table 6.5.2.2.1-1.

6.5.2.3 In-band emissions
The in-band emission is defined as the average across 12 sub-carrier and as a function of the RB offset from the edge of the allocated UL transmission bandwidth. The in-band emission is measured as the ratio of the UE output power in a non–allocated RB to the UE output power in an allocated RB.
The basic in-band emissions measurement interval is defined over one slot in the time domain. When the PUSCH or PUCCH transmission slot is shortened due to multiplexing with SRS, the in-band emissions measurement interval is reduced by one SC-FDMA symbol, accordingly. Likewise, when the PUSCH starting position is modified or when the second last symbol is the ending symbol of the PUSCH sub-frame for Frame Structure Type 3, the in-band emissions measurement interval is reduced accordingly.
6.5.2.3.1 Minimum requirements
The relative in-band emission shall not exceed the values specified in Table 6.5.2.3.1-1.

NOTE 1: An in-band emissions combined limit is evaluated in each non-allocated RB. For each such RB, the minimum requirement is calculated as the higher of PRB – 30 dB and the power sum of all limit values (General, IQ Image or Carrier leakage) that apply. PRB is defined in NOTE 10. NOTE 2: The measurement bandwidth is 1 RB and the limit is expressed as a ratio of measured power in one non-allocated RB to the measured average power per allocated RB, where the averaging is done across all allocated RBs. For Frame Structure Type 3 and 20 MHz channel bandwidth, the requirement applies for QPSK, 16QAM and 64QAM modulation with for any non-allocated RB andin the uplink scheduling grant with specified in [6]. For Frame Structure Type 3 and 10 MHz channel bandwidth in Band 49, the requirement applies for QPSK, 16QAM and 64QAM modulation with for any non-allocated RB andin the uplink scheduling grant. NOTE 3: The applicable frequencies for this limit are those that are enclosed in the reflection of the allocated bandwidth, based on symmetry with respect to the centre carrier frequency, but excluding any allocated RBs. For Frame Structure Type 3 with 20 MHz channel bandwidth, the applicable frequency is for QPSK, 16QAM and 64QAM modulation. For Frame Structure Type 3 and 10 MHz channel bandwidth in Band 49, the applicable frequency is for QPSK, 16QAM and 64QAM modulation. NOTE 4: The measurement bandwidth is 1 RB and the limit is expressed as a ratio of measured power in one non-allocated RB to the measured total power in all allocated RBs. For Frame Structure Type 3 and 20 MHz channel bandwidth, the requirement applies for QPSK, 16QAM and 64QAM modulation within the uplink scheduling grant. For Frame Structure Type 3 and 10 MHz channel bandwidth in Band 49, the requirement applies for QPSK, 16QAM and 64QAM modulation within the uplink scheduling grant. NOTE 5: The applicable frequencies for this limit are those that are enclosed in the RBs containing the DC frequency if is odd, or in the two RBs immediately adjacent to the DC frequency if is even, but excluding any allocated RB.

NOTE 10: is the transmitted power per 180 kHz in allocated RBs, measured in dBm. [NOTE 11: For V2V-V2X waveforms, the requirements are applied when PSSCH and PSCCH are adjacent in frequency. The limit values (General, IQ Image or Carrier leakage) of each channel is calculated separately as Pgeneral, PSSCH, PIQ, PSSCH, PLO, PSSCH, Pgeneral, PSCCH, PIQ, PSCCH, PLO, PSCCH ,respectively. In-band emissions combined limit is evaluated in each non-allocated RB. For each such RB, the minimum requirement is calculated as the higher of PRB, PSSCH – 30 dB and the PsumIBE.SSCH, where PsumIBE.SSCH is the linear sum of Pgeneral, PSSCH, PIQ, PSSCH, PLO, PSSCH, Pgeneral, PSCCH, PIQ, PSCCH, PLO, PSCCH.] NOTE 12: The requirement in this power range is not applicable for V2X sidelink transmission for E-UTRA V2X operating bands specified in Table 5.5G-1. |
NOTE: For Frame Structure 3 and operations in Band 46, in-band emissions requirements are not specified for the 10 MHz channel bandwidth.
6.5.2.4 EVM equalizer spectrum flatness
The zero-forcing equalizer correction applied in the EVM measurement process (as described in Annex F) must meet a spectral flatness requirement for the EVM measurement to be valid. The EVM equalizer spectrum flatness is defined in terms of the maximum peak-to-peak ripple of the equalizer coefficients (dB) across the allocated uplink block. The basic measurement interval is the same as for EVM.
6.5.2.4.1 Minimum requirements
The peak-to-peak variation of the EVM equalizer coefficients contained within the frequency range of the uplink allocation shall not exceed the maximum ripple specified in Table 6.5.2.4.1-1 for normal conditions. For uplink allocations contained within both Range 1 and Range 2, the coefficients evaluated within each of these frequency ranges shall meet the corresponding ripple requirement and the following additional requirement: the relative difference between the maximum coefficient in Range 1 and the minimum coefficient in Range 2 must not be larger than 5 dB, and the relative difference between the maximum coefficient in Range 2 and the minimum coefficient in Range 1 must not be larger than 7 dB (see Figure 6.5.2.4.1-1).
The EVM equalizer spectral flatness shall not exceed the values specified in Table 6.5.2.4.1-2 for extreme conditions. For uplink allocations contained within both Range 1 and Range 2, the coefficients evaluated within each of these frequency ranges shall meet the corresponding ripple requirement and the following additional requirement: the relative difference between the maximum coefficient in Range 1 and the minimum coefficient in Range 2 must not be larger than 6 dB, and the relative difference between the maximum coefficient in Range 2 and the minimum coefficient in Range 1 must not be larger than 10 dB (see Figure 6.5.2.4.1-1).

The requirements in this clause apply with PCC and SCC in the UL configured and activated: PCC with PRB allocation and SCC without PRB allocation and without CSI reporting and SRS configured.
6.5.2A.1 Error Vector Magnitude
For the intra-band contiguous and non-contiguous carrier aggregation, the Error Vector Magnitude requirement should be defined for each component carrier. Requirements only apply with PRB allocation in one of the component carriers. Similar transmitter impairment removal procedures are applied for CA waveform before EVM calculation as is specified for non-CA waveform in sub-section 6.5.2.1.
When a single component carrier is configured Table 6.5.2.1.1-1 apply.
The EVM requirements are according to Table 6.5.2A.1-1 if CA is configured in uplink with the parameters defined in Table 6.5.2.1.1-2.

PRB is defined in NOTE 10. NOTE 2: The measurement bandwidth is 1 RB and the limit is expressed as a ratio of measured power in one non-allocated RB to the measured average power per allocated RB, where the averaging is done across all allocated RBs. NOTE 3: The applicable frequencies for this limit are those that are enclosed in the reflection of the allocated bandwidth, based on symmetry with respect to the centre carrier frequency, but excluding any allocated RBs. For UE of UL Categories M1 and M2, the applicable frequencies shall alternatively include those found by reflection on the center of the assigned narrowband, but excluding any allocated RBs. NOTE 4: The measurement bandwidth is 1 RB and the limit is expressed as a ratio of measured power in one non-allocated RB to the measured total power in all allocated RBs. NOTE 5: The applicable frequencies for this limit are those that are enclosed in the RBs containing the DC frequency if is odd, or in the two RBs immediately adjacent to the DC frequency if is even, but excluding any allocated RB. For UE of UL Categories M1 and M2, the applicable frequencies shall alternatively be the centre frequency of the supported 6RBs. NOTE 6: is the Transmission Bandwidth (see Figure 5.6-1). NOTE 7: is the Transmission Bandwidth Configuration (see Figure 5.6-1). NOTE 8: is the limit specified in Table 6.5.2.1.1-1 for the modulation format used in the allocated RBs.
