6.4A.1 Frequency error for CA
38.521-23GPPNRPart 2: Range 2 StandaloneRadio transmission and receptionRelease 17TSUser Equipment (UE) conformance specification
6.4A.1.0 Minimum conformance requirements
The requirements in this clause apply to UEs of all power classes.
For intra-band 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.
The frequency error is defined as a directional requirement. The requirement is verified in beam locked mode on beam peak direction.
6.4A.1.1 Frequency error for CA (2UL CA)
Editor’s note: This clause is incomplete. The following aspects are either missing or not yet determined:
- Measurement Uncertainties and Test Tolerances for intra-band contiguous CA supporting aggregated BW > 400MHz is TBD.
- Measurement Uncertainties and Test Tolerances are FFS for power class 1, 2 and 4.
6.4A.1.1.1 Test purpose
This test verifies the ability of both, the receiver and the transmitter, to process frequency correctly.
Receiver: to extract the correct frequency from the stimulus signal, offered by the System simulator, under ideal propagation conditions and low level.
Transmitter: to derive the correct modulated carrier frequency from the results, gained by the receiver.
6.4A.1.1.2 Test applicability
This test case applies to all types of NR UE release 15 and forward that supports FR2 2UL CA.
6.4A.1.1.3 Minimum conformance requirements
The minimum conformance requirements are defined in clause 6.4A.1.0.
6.4A.1.1.4 Test description
6.4A.1.1.4.1 Initial condition
Initial conditions are a set of test configurations the UE needs to be tested in and the steps for the SS to take with the UE to reach the correct measurement state.
The initial test configurations consist of environmental conditions, test frequencies, and channel bandwidths based on NR operating bands specified in clause 5.5A. All of these configurations shall be tested with applicable test parameters for each channel bandwidth and subcarrier spacing, are shown in Table 6.4A.1.1.4.1-1. The details of the uplink reference measurement channels (RMCs) are specified in Annexes A.2. Configurations of PDSCH and PDCCH before measurement are specified in Annex C.2.

1. Connection between SS and UE is shown in TS 38.508-1 [10] Annex A, Figure A.3.3.1.1 for TE diagram and Figure A.3.4.1.1 for UE diagram.
2. The parameter settings for the cell are set up according to TS 38.508-1 [10] subclause 4.4.3.
3. Downlink signals are initially set up according to Annex C, and uplink signals according to Annex G.
4. The UL Reference Measurement channels are set according to Table 6.4A.1.1.4.1-1.
5. Propagation conditions are set according to Annex B.0
6. Ensure the UE is in state RRC_CONNECTED with generic procedure parameters Connectivity NR, Connected without release On, Test Mode On and Test Loop Function On according to TS 38.508-1 [10] clause 4.5. Message contents are defined in clause 6.4A.1.1.4.3
6.4A.1.1.4.2 Test procedure
1. Retrieve the LO position from the parameter txDirectCurrentLocation in UplinkTxDirectCurrent IE.
2. Configure SCC according to Annex C.0, C.1, C.2 for all downlink physical channels.
3. The SS shall configure SCC as per TS 38.508-1 [10] clause 5.5.1. Message contents are defined in clause 6.4A.1.1.4.3.
4. SS activates SCC by sending the activation MAC CE (Refer TS 38.321 [28], clauses 5.9, 6.1.3.10). Wait for at least 2 seconds (Refer TS 38.133[25], clause 9.3).
5. SS transmits PDSCH via PDCCH DCI format 1_1 for C_RNTI to transmit the DL RMC according to Table 6.4A.1.1.4.1-1. The SS sends downlink MAC padding bits on the DL RMC.
6. SS sends uplink scheduling information for each UL HARQ process via PDCCH DCI format 0_1 for C_RNTI to schedule the UL RMC according to Table 6.4A.1.1.4.1-1. Since the UL has no payload and no loopback data to send the UE sends uplink MAC padding bits on the UL RMC.
7. Set the UE in the Inband Tx beam peak direction found with a 3D EIRP scan as performed in Annex K.1.1. Allow at least BEAM_SELECT_WAIT_TIME (NOTE 1) for the UE Tx beam selection to complete.
8. Send continuously uplink power control "up" commands to the UE in every uplink scheduling information to the UE so that the UE transmits at PUMAX level for the duration of the test. Allow at least 200ms starting from the first TPC Command for the UE to reach PUMAX level. Allow at least BEAM_SELECT_WAIT_TIME (NOTE 1) for the UE Tx beam selection to complete.
9. SS activates the UE Beamlock Function (UBF) by performing the procedure as specified in TS 38.508-1 [10] clause 4.9.2 using condition Tx only.
10. For every UE modulated carrier frequency, measure the Frequency Error using Global In-Channel Tx-Test (Annex E) for the θ- and φ-polarization. For TDD, only slots consisting of only UL symbols are under test.
NOTE 1: The BEAM_SELECT_WAIT_TIME default value is defined in Annex K.1.1.
