5G; NR; User Equipment (UE) conformance specification; Radio transmission and reception; Part 3: Range 1 and Range 2 Interworking operation with other radios (V15.0.0; 3GPP TS 38.521-3 version 15.0.0 Release 15)
"The present document specifies the measurement procedures for the conformance test of the user equipment (UE) that contain RF characteristics for carrier aggregation between Range 1 and Range 2 and additional requirements due to NR non-standalone (NSA) operation mode with E-UTRA. The requirements are listed in different clauses only if the corresponding parameters deviate. More generally@ tests are only applicable to those mobiles that are intended to support the appropriate functionality. To indicate the circumstances in which tests apply@ this is noted in the ""definition and applicability"" part of the test. For example only Release 15 and later UE declared to support 5G-NR shall be tested for this functionality. In the event that for some tests different conditions apply for different releases@ this is indicated within the text of the test itself."
