2 presented to TSG for approval;
3 or greater indicates TSG approved document under change control.
y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections,
updates, etc.
z the third digit is incremented when editorial only changes have been incorporated in the document.
In the present document, modal verbs have the following meanings:
shall indicates a mandatory requirement to do something
shall not indicates an interdiction (prohibition) to do something
The constructions "shall" and "shall not" are confined to the context of normative provisions, and do not appear in
Technical Reports.
The constructions "must" and "must not" are not used as substitutes for "shall" and "shall not". Their use is avoided
insofar as possible, and they are not used in a normative context except in a direct citation from an external, referenced,
non-3GPP document, or so as to maintain continuity of style when extending or modifying the provisions of such a
referenced document.
should indicates a recommendation to do something
should not indicates a recommendation not to do something
may indicates permission to do something
need not indicates permission not to do something
The construction "may not" is ambiguous and is not used in normative elements. The unambiguous constructions
"might not" or "shall not" are used instead, depending upon the meaning intended.
can indicates that something is possible
cannot indicates that something is impossible
The constructions "can" and "cannot" are not substitutes for "may" and "need not".
will indicates that something is certain or expected to happen as a result of action taken by an agency
the behaviour of which is outside the scope of the present document
will not indicates that something is certain or expected not to happen as a result of action taken by an
agency the behaviour of which is outside the scope of the present document
might indicates a likelihood that something will happen as a result of action taken by some agency the
behaviour of which is outside the scope of the present document
ETSI
3GPP TS 36.523-2 version 19.2.0 Release 19 6 ETSI TS 136 523-2 V19.2.0 (2026-04)
might not indicates a likelihood that something will not happen as a result of action taken by some agency
the behaviour of which is outside the scope of the present document
In addition:
is (or any other verb in the indicative mood) indicates a statement of fact
is not (or any other negative verb in the indicative mood) indicates a statement of fact
The constructions "is" and "is not" do not indicate requirements.
Introduction
To evaluate conformance of a particular implementation, it is necessary to have a statement of which capabilities and
options have been implemented for a telecommunication specification. Such a statement is called an Implementation
Conformance Statement (ICS).
The present document is part 2 of a multi-part conformance test specification for User Equipment (UE).
3GPP TS 36.523-1 [19]: "Evolved Universal Terrestrial Radio Access (E-UTRA) and Evolved Packet Core
(EPC); User Equipment (UE) conformance specification; Part 1: Protocol conformance specification".
3GPP TS 36.523-2: "Evolved Universal Terrestrial Radio Access (E-UTRA) and Evolved Packet Core (EPC);
User Equipment (UE) conformance specification; Part 2: Implementation Conformance Statement (ICS)
proforma specification". (the present document)
3GPP TS 36.523-3 [20]: "Evolved Universal Terrestrial Radio Access (E-UTRA) and Evolved Packet Core
(EPC); User Equipment (UE) conformance specification; Part 3: Abstract Test Suite (ATS)".

4 Recommended Test Case Applicability
The applicability of each individual test is identified in Table 4-1. This is just a recommendation based on the purpose
for which the test case was written.
The applicability of every test is formally expressed by the use of Boolean expression that are based on parameters
(ICS) included in annex A of the present document. The parameters (ICS) shall be set according to the capabilities of
the UE on the operating band / band combination under test.
Additional information related to the Test Case (TC), e.g. affecting its dynamic behaviour or its execution may be
provided as well.
When a test case is to be executed against a category M1 UE and with IMS enabled, it is assumed that the UE is
compliant to GSMA profile NG.108 [55].
The columns in Table 4-1 have the following meaning:
Clause
The clause column indicates the clause number in TS 36.523-1 [19] 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 36.523-1 [19] that
contains the test body.
ETSI
3GPP TS 36.523-2 version 19.2.0 Release 19 11 ETSI TS 136 523-2 V19.2.0 (2026-04)
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 'Release' e.g. see Note 3
Table 4-1.
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 an 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 1: The conditions are defined in Table 4-1a.
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.
NOTE 1A: ICS items specified in 3GPP TS 34.123-2 [8] and 3GPP TS 34.229-2 [45] can be referred, to avoid
redundant definitions.
NOTE 1B: The ICS items pc_eFDD and pc_eFDD, as well as pc_NB_FDD and pc_NB_TDD, specified in the
present document (Table A.4.1-1) are used to identify that a test case can be run in FDD or/and TDD
branch. When none of them is provided it is assumed that the test case requires both FDD and TDD.
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 in Table 4-1b.
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 E-UTRA) 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), a Note extending the release
applicability to an earlier version for E-UTRA in the ‘Release’ column is not applicable to the other RATs.
EXAMPLES:
Rel-9 UTRA FDD, Rel-8 GERAN or simply as Rel-9 UTRA FDD
(meaning that the UTRA FDD will simulate Rel-9 and the GERAN Rel-8 behaviours)

NOTE 2: To meet the validation requirements from certification bodies then there is a need to uniquely reference the FDD and TDD branch of common FDD and TDD test
cases. The FDD and TDD branches of common FDD and TDD test cases can be referenced by amending a "FDD" or "TDD" suffix to the test case clause number.
For example for AM RLC test case 7.2.3.13 the FDD and TDD branches can be identified by "7.2.3.13 FDD" and "7.2.3.13 TDD".
