7.8.1EC Wide band intermodulation 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

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

7.8.1EC.1 Test purpose

Same as in clause 7.8.1EA.1

7.8.1EC.2 Test applicability

This test applies to all types of E-UTRA UE release 14 and forward of category M2.

7.8.1EC.3 Minimum conformance requirements

The throughput shall be ≥ 95% of the maximum throughput of the reference measurement channels as specified in Annexes A.2.2, A.2.3 and A.3.2 (with one sided dynamic OCNG Pattern OP.1 FDD/TDD for the DL-signal as described in Annex A.5.1.1/A.5.2.1) with parameters specified in Table 7.8.1EC.3-1 for the specified wanted signal mean power in the presence of two interfering signals. For operating bands with an unpaired DL part (as noted in Table 5.2-1), the requirements only apply for carriers assigned in the paired part.

Note 1: The transmitter shall be set to 4dB below PCMAX_L at the minimum uplink configuration specified in Table 7.3EA-3 with PCMAX_L as defined in clause 6.2.5EA. Note 2: The reference measurement channel is specified in Annex A.3.2 with one sided dynamic OCNG Pattern OP.1 FDD/TDD as described in Annex A.5.1.1/A.5.2.1. Note 3: The modulated interferer consists of the Reference measurement channel specified in Annex A.3.2 with one sided dynamic OCNG Pattern OP.1 FDD/TDD as described in Annex A.5.1.1/A.5.2.1 with set-up according to Annex C.3.1.The interfering modulated signal is 5MHz E-UTRA signal as described in Annex D for channel bandwidth ≥5MHz. Note 4: For DL category M1 and M2 UE, the reference sensitivity for category M1 in table 7.3EA-1 and 7.3EA-2 and category M2 in Table 7.3EC-1 should be used as REFSENS for the power in Transmission Bandwidth Configuration. Note 5: For DL category M1 and M2 UE, the parameters for the applicable channel bandwidth apply, and BW refers to the corresponding channel bandwidth.

The normative reference for this requirement is TS 36.101 [2] clause 7.8.1.
