1 Scope
The present document provides the applicability of protocol test cases proforma for 5G New Radio (NR) User
Equipment (UE), in compliance with the relevant requirements.
The present document specifies the recommended applicability statement for the test cases included in 3GPP TS
38.523-1 [2] and 3GPP TS 38.523-3 [3]. These applicability statements are based on the features implemented in the
UE.
Special conformance testing functions can be found in 3GPP TS 38.509 [5] and 3GPP TS 36.509 [7] and the common
test environments are included in 3GPP TS 38.508-1 [4] and 3GPP TS 36.508 [6].
The present document is valid for UE implemented according to 3GPP Releases starting from Release 15 up to the
Release indicated on the cover page of the present document.
