which contains or references all of the information (in addition to that given in the ICS) related to the UEUT and its
testing environment, which will enable the test laboratory to run an appropriate test suite against the UEUT

4 Recommended Test Case Applicability
4.0 Introduction
The applicability of each individual test is identified in subclause 4.1. This is just a recommendation based on the
purpose for which the test case was written.
ETSI
---------------------- Page: 7 ----------------------
3GPP TS 38.523-2 version 16.4.0 Release 16 7 ETSI TS 138 523-2 V16.4.0 (2020-07)
The applicability of every test is formally expressed by the use of Boolean expressions that are based on parameters
(ICS). The parameters (ICS) included in TS 38.508-2 [5] are used in the test case applicability condition without
reference. Parameters (ICS) specified in 3GPP TS 36.523-2 [10] and 3GPP TS 34.229-2 [9] shall be referred with
proper reference.
Additional information related to the Test Case (TC), e.g. affecting its dynamic behaviour or its execution may be
provided as well
The columns in subclause 4.1 have the following meaning:
Clause
The clause column indicates the clause number in TS 38.523-1 [2] that contains the test body.
Title
The title column describes the name of the test and contains the clause title of the clause in TS 38.523-1 [2] that
contains the test body.
Release
The release column indicates the earliest release from which the test case is applicable. In some specific cases it may
indicate the release(s) for which the TC is only applicable.
Note: Some exceptions to this interpretation may be indicated in Notes in column 'Number of TC Executions'.
Applicability - Condition
The following notations are used for the applicability column:
R recommended - the test case is recommended
O optional – the test case is optional
N/A not applicable - in the given context, the test case is not recommended.
Ci conditional - the test is recommended ("R") or not ("N/A") depending on the support of other
items. "i" is an integer identifying a unique conditional status expression which is defined
immediately following the table. For nested conditional expressions, the syntax "IF . THEN (IF .
THEN . ELSE.) ELSE ." is used to avoid ambiguities.
NOTE: The conditions are defined in subclause 4.2.
Applicability - Comments
This column contains a verbal description of the condition.
Additional Information - Specific ICS
This column contains the mnemonics of ICS(s) affecting the dynamic behaviour of the TC.
Additional Information - Specific IXIT
This column contains the mnemonics of IXIT(s) affecting the dynamic behaviour of the TC.
Additional Information - Number of TC Executions
This column contains, wherever applicable, the recommended for certification purposes number of TC
executions. It may contain also other information e.g. exceptions to the release applicable to the test. Clarifying
notes are listed at the end of the same Table.

Additional Information - Release other RAT
In regard to a particular test case, this column provides information on the release which is used by the simulated
network in the other (i.e. non 5GS) RAT(s) where applicable. For each applicable RAT the release shall be
indicated in the format 'Rel-X RAT'. When multiple RATs are applicable the entries per RAT shall be separated
by a comma. When a value for a 3GPP RAT is not provided but the RAT is in the scope of the test case then for
this RAT the release indicated in the Release column applies (per default).
