7.9_1 Spurious emissions with 4 Rx antenna ports
36.521-13GPPEvolved Universal Terrestrial Radio Access (E-UTRA)Part 1: Conformance testingRadio transmission and receptionRelease 17TSUser Equipment (UE) conformance specification
7.9_1.1 Test Purpose
Test verifies the UE’s spurious emissions meet the requirements described in clause 7.9_1.3.
Excess spurious emissions increase the interference to other systems.
7.9_1.2 Test Applicability
This test applies to all types of E-UTRA UE release 10 and forward that supports 4 Rx antenna ports.
7.9_1.3 Minimum Conformance Requirements
Same minimum conformance requirements as in clause 7.9.3.
7.9_1.4 Test Description
7.9_1.4.1 Initial Conditions
Same as in clause 7.9.4.1 with following exceptions:
– Instead of Table 7.9.4.1-1🡪 use Table 7.9_1.4.1-1.
– Instead of Figure A.8🡪 use Figure A.83 configuration Table.
