Tools: ARFCN - Frequency Conversion for 5G NR/LTE/UMTS/GSM

6.4A.0 General

For intra-band contiguous and non-contiguous carrier aggregation, the requirements in this clause apply if the UE has at least one of UL or DL configured for CA.

6.4A.1 Frequency error

The requirements in this clause apply to UEs of all power classes.

For intra-band contiguous and non-contiguous carrier aggregation, the UE basic measurement interval of modulated carrier frequency is 1 UL slot. The mean value of basic measurements of UE modulated carrier frequencies per band shall be accurate to within ± 0.1 PPM observed over a period of 1ms of cumulated measurement intervals compared to the carrier frequency of primary component carrier received from the gNB.

For inter-band carrier aggregation with uplink assigned to two NR bands, and each UL band is configured with a single CC, the frequency error requirement is specified in clause 6.4.1 and is applicable for each CC with all CCs active with non-zero UL RB allocation.

The frequency error is defined as a directional requirement. The requirement is verified in beam locked mode on beam peak direction.

6.4A.2 Transmit modulation quality

6.4A.2.0 General

For intra-band contiguous and non-contiguous carrier aggregation, the requirements in clauses 6.4A.2.1, 6.4A.2.2, and 6.4A.2.3.

All the parameters defined in clause 6.4A.2 are defined using the measurement methodology specified in Annex F.

All the requirements in 6.4A.2 are defined as directional requirement. The requirements are verified in beam locked mode on beam peak direction.

For inter-band carrier aggregation with uplink assigned to two NR bands, and each UL band is configured with a single CC, the transmit modulation quality requirements are specified in clause 6.4.2 and are applicable for each CC with all CCs active with non-zero UL RB allocation.

6.4A.2.1 Error Vector magnitude

The requirements in this clause apply to UEs of all power classes. For intra-band contiguous and non-contiguous carrier aggregation, the Error Vector Magnitude requirement of clause 6.4.2.2 is 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 case the parameter 3300 or 3301 is reported from UE via the parameter txDirectCurrentLocation in UplinkTxDirectCurrenList IE (as defined in TS 38.331 [13]), carrier leakage measurement requirement in clause 6.4A.2.2 and 6.4A.2.3 shall be waived, and the RF correction with regard to the carrier leakage and IQ image shall be omitted during the calculation of transmit modulation quality.

For intra-band contiguous and non-contiguous carrier aggregation, the UE is defined to be configured for CA operation when it has at least one of UL or DL configured for CA.

For inter-band carrier aggregation with uplink assigned to two NR bands, and each UL band is configured with a single CC, the Error Vector Magnitude requirements are specified in clause 6.4.2.1 and are applicable for each CC with all CCs active with non-zero UL RB allocation.

6.4A.2.2 Carrier leakage

6.4A.2.2.1 General

Carrier leakage is an additive sinusoid waveform. The carrier leakage requirement is defined for each component carrier and is measured on the component carrier with PRBs allocated. The measurement interval is one slot in the time domain.

Note: When UE has DL configured for intra-band non-contiguous CA, carrier leakage may land outside the spectrum occupied by all configured UL and DL CC.

The relative carrier leakage power is a power ratio of the additive sinusoid waveform and the modulated waveform. The requirement is verified with the test metric of Carrier Leakage (Link=TX beam peak direction, Meas=Link angle).
