6.5B.4 Additional Spurious Emissions for EN-DC
38.521-33GPPNRPart 3: Range 1 and Range 2 Interworking operation with other radiosRadio transmission and receptionRelease 17TSUser Equipment (UE) conformance specification
6.5B.4.1 Additional Spurious Emissions for Intra-band contiguous EN-DC
6.5B.4.1.1 Test purpose
To verify that UE transmitter does not cause unacceptable interference to other channels or other systems in terms of transmitter spurious emissions under the deployment scenarios where additional requirements are specified.
6.5B.4.1.2 Test applicability
This test case applies to all types of E-UTRA UE release 15 and forward supporting intra-band contiguous EN-DC.
6.5B.4.1.3 Minimum conformance requirements
These requirements are specified in terms of an additional spectrum emission requirement. Additional spurious emission requirements are signalled by the network to indicate that the UE shall meet an additional requirement for a specific deployment scenario as part of the cell handover/broadcast message.
NOTE: For measurement conditions at the edge of each frequency range, the lowest frequency of the measurement position in each frequency range should be set at the lowest boundary of the frequency range plus MBW/2. The highest frequency of the measurement position in each frequency range should be set at the highest boundary of the frequency range minus MBW/2. MBW denotes the measurement bandwidth defined for the protected band.
6.5B.4.1.3.1 Minimum requirement (network signalled value "NS_04")
When "NS 04" is indicated in the cell, the power of any UE emission shall not exceed the levels specified in Table 6.5B.4.1.3.1-1. This requirement also applies for the frequency ranges that are less than FOOB (MHz) in Table 6.5.3.1.3-1 of TS 38.521-1 [8] from the edge of the channel bandwidth.

6.5B.4.1.4 Test description
6.5B.4.1.4.1 Initial conditions
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, test channel bandwidths and sub-carrier spacing based on EN-DC operating bands specified in 5.3B.1.2. All of these configurations shall be tested with applicable test parameters for each combination of test channel bandwidth and sub-carrier spacing are shown in Table 6.5B.4.1.4.1-1 for both E-UTRA and NR. The details of the uplink reference measurement channels (RMCs) are specified in Annex A.2 for NR. Configurations of PDSCH and PDCCH before measurement are specified in TS 36.521-1 [10] Annex C and in TS 38.521-1 [8] Annex C2 for LTE link and NR link respectively.

6.5B.4.1.4.2 Test Procedure
1. E-UTRA SS sends uplink scheduling information for each UL HARQ process via PDCCH DCI format 0 for C_RNTI to schedule the UL RMC according to Table 6.5B.4.1.4.1-1. Since the UE has no payload data to send, the UE transmits uplink MAC padding bits on the UL RMC.
2. NR 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 6.5B.4.1.4.1-1. Since the UE has no payload data to send, the UE transmits uplink MAC padding bits on the UL RMC.
3. Send continuously uplink power control "up" commands to the UE for both NR and E-UTRA carriers until the UE transmits at its PUMAX level; allow at least 200 ms starting from the first TPC command in this step for the UE to reach PUMAX level.
4. Measure the mean power of each component carriers for the EN-DC configuration, which shall meet the requirements described in 6.2B.3.1.5.2 depending on NS-values. The period of the measurement shall be at least the continuous duration of one sub-frame.
5. Measure the power of the transmitted signal with a measurement filter of bandwidths according to Table 6.5B.4.1.3.1-1. The centre frequency of the filter shall be stepped in contiguous steps according to the same table. The measured power shall be recorded for each step. The measurement period shall capture the active time slots.
6.5B.4.1.4.3 Message Contents
Message contents are according to TS 38.508-1 [6] clause 4.6 with the following exceptions for each network signalled value.
6.5B.4.1.4.3.1 Message contents exceptions for network signalled value "NS_04"
1. Information element additionalSpectrumEmission is set to NS_04. This can be set in SIB1 as part of the cell broadcast message. This exception indicates that the UE shall meet the additional spurious emission requirement for a specific deployment scenario.
