7.9EC Spurious emissions for UE category M2
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.
7.9EC.1 Test Purpose
Same test purpose as in clause 7.9EA.1.
7.9EC.2 Test Applicability
This test applies to all types of E-UTRA UE release 14 and forward of UE category M2.
7.9EC.3 Minimum Conformance Requirements
Same minimum conformance requirements as in clause 7.9EA.3.
7.9EC.4 Test Description
7.9EC.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 bands specified in clause 5.2E. All of these configurations shall be tested with applicable test parameters for each channel bandwidth, and are shown in table 7.9EC.4.1-1. The details of the uplink and downlink reference measurement channels (RMCs) are specified in Annexes A.2 and A.3 respectively.

Note 1: Denotes the lowest narrowband index in the channel bandwidth where the wideband shall be placed. The allocation is contiguous, starting from the lowest narrowband index. Narrowband, Narrowband index and Wideband are defined in TS 36.211 [8], 5.2.7. |
1. Connect a spectrum analyzer (or other suitable test equipment) to the UE antenna connectors as shown in TS 36.508 [7] Annex A, Figure A.7 using only main UE Tx/Rx antenna.
2. The parameter settings for the cell are set up according to TS 36.508 [7] subclause 4.4.3.
3. Downlink signals are initially set up according to Annex C.0, C.1 and C.3.1.
4. The DL Reference Measurement channels are set according to Table 7.9EC.4.1-1.
5. Propagation conditions are set according to Annex B.0.
6. Ensure the UE is in State 3A-RF-CE according to TS 36.508 [7] clause 5.2A.2AA. Message contents are defined in clause 7.9EC.4.3.
7.9EC.4.2 Test Procedure
1. Sweep the spectrum analyzer (or equivalent equipment) over a frequency range and measure the average power of spurious emission.
7.9EC.4.3 Message Contents
Message contents are according to TS 36.508 [7] subclause 4.6.
7.9EC.5 Test Requirement
The measured spurious emissions derived in step 1), shall not exceed the maximum level specified in Table 7.9EC.5-1.
