7.9A Spurious emissions for CA
36.521-13GPPEvolved Universal Terrestrial Radio Access (E-UTRA)Part 1: Conformance testingRadio transmission and receptionRelease 17TSUser Equipment (UE) conformance specification
The spurious emissions power is the power of emissions generated or amplified in a receiver that appear at the UE antenna connector.
7.9A.1 Test Purpose
Test verifies the UE’s spurious emissions meet the requirements described in clause 7.9A.3.
Excess spurious emissions increase the interference to other systems.
7.9A.2 Test Applicability
This test applies to all types of E-UTRA UE release 10 and forward that support inter-band DL CA with a DL-only band.
7.9A.3 Minimum Conformance Requirements
For E-UTRA CA configurations including an operating band without uplink band (as noted in Table 5.2-1), the power of any narrow band CW spurious emission shall not exceed the maximum level specified in Table 7.9A.3-1.

7.9A.4 Test Description
7.9A.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, and channel bandwidths based on E-UTRA CA bands specified in Table 5.4.2A.1-1 and Table 5.4.2A.1-2. All of these configurations shall be tested with applicable test parameters for each CA Configuration, and are shown in Table 7.9A.4.1-1. The details of the uplink reference measurement channels (RMCs) are specified in Annexe A.2. Configurations of PDSCH and PDCCH before measurement are specified in Annex C.2.

Note 1: CA Configuration Test CC Combination settings are checked separately for each CA Configuration, which applicable aggregated channel bandwidths are specified in Table 5.4.2A.1-2. |
1. Connect the SS to the UE antenna connectors as shown in Figure TS 36.508 [7] Annex A, Figure A.8a as appropriate if the UE supports 2 Rx antennas or Figure TBD if the UE supports 4 Rx antennas in the band.
2. The parameter settings for the cell are set up according to TS 36.508 [7] subclause 4.4.3.
3. Downlink signals for PCC are initially set up according to Annex C.0, C.1 and Annex C.3.0.
4. Propagation conditions are set according to Annex B.0.
5. Ensure the UE is in State 3A-RF according to TS 36.508 [7] clause 5.2A.2. Message contents are defined in clause 7.9A.4.3.
7.9A.4.2 Test Procedure
1. Configure SCC according to Annex C.0, C.1 and Annex C.3.1 for all downlink physical channels.
2. The SS shall configure SCC as per TS 36.508 [7] clause 5.2A.4. Message contents are defined in clause 7.9A.4.3.
3. SS activates SCC by sending the activation MAC-CE (Refer TS 36.321 [13], clauses 5.13, 6.1.3.8). Wait for at least 2 seconds (Refer TS 36.133, clauses 8.3.3.2).
4. Sweep the spectrum analyzer (or equivalent equipment) over a frequency range and measure the average power of spurious emission. During measurement SS sends no uplink scheduling information to the UE
5. Repeat step 4 for all E-UTRA Rx antennas of the UE.
7.9A.4.3 Message Contents
Message contents are according to TS 36.508 [7] subclause 4.6.
