Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Intelligent Transport System (ITS).
The present document is part 1, sub-part 2 of a multi-part deliverable covering the test specifications for High Data

1 Scope
The present document contains the Test Suite Structure (TSS) and Test Purposes (TP) to test the "Dedicated Short
Range Communication" (DSRC) "High Data Rate" (HDR) data link layer [1].
The objective of this test specification is to provide a basis for conformance tests for DSRC-HDR equipment specified
in [1] giving a high probability of inter-operability between different manufacturer's equipment.
The ISO standard for the methodology of conformance testing (ISO/IEC 9646-1 [3]) is used as a basis for the test
methodology.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in [1] and [3] apply.
3.2 Abbreviations
For the purposes of the present document, the abbreviations given in [1] and [3] apply.
4 Test Suite Structure
4.1 Structure
Table 1 shows the DLL Test Suite Structure (TSS) including its subgroups defined for the conformance testing.
Table 1: Test suite structure for DSRC-HDR data link layer
Group Type of system under test (SUT) Behaviour
Data link layer On Board Unit Valid behaviour
Invalid behaviour
Road Side Unit Valid behaviour
Invalid behaviour

4.2 Test groups
There is a single test group for the data link layer of DSRC-HDR.
4.3 Type of SUT
Two types of systems under test (SUT) are distinguished, i.e. on board units (OBUs) and road side units (RSUs).
4.4 Behaviour test groups
4.4.1 Valid behaviour tests
Valid behaviour tests shall verify that the IUT reacts in conformity with the base standard [1], after receipt or exchange
of valid protocol data units (PDUs). "Valid PDU" means that the exchange of messages and the content of the
exchanged messages are considered as valid, i.e compliant with the base standard.
4.4.2 Invalid behaviour tests
Invalid behaviour tests shall verify that the IUT reacts in conformity with the base standard [1], after receipt of a
syntactically invalid protocol data unit (PDU).

5 Test purposes
5.1 Introduction
5.1.1 Definition conventions
Test purposes (TPs) are defined following particular rules as presented in table 2.
Table 2: TP definition rules
TP ID Title:
Reference:
PICS Selection:
TC Reference
Initial condition:
Stimulus and Expected behaviour:

TP ID The TP ID is a unique identifier. It shall be specified according to the TP naming
conventions defined in the sub-clause below.
Title Short description of test purpose objective.
Reference The reference should contain the references of the subject to be validated by the actual
TP (specification reference, clause, paragraph).
ICS Selection Reference to the ICS statement involved for selection of the TP. Contains a Boolean
expression. Only those ICS statements are shown that are explicitly related to the test.
TC reference
Shows the reference number of the related test case in the ATS.
Initial condition The condition defines in which initial state the IUT has to be to apply the actual TP.
Stimulus and Expected Definition of the events the tester performs, and the events that are expected from the
behaviour
IUT to conform to the base specification.

5.1.2 Naming conventions
The identifier of the TP is built according to table .
Table 3: TP naming convention
Identifier TP////
= Type of SUT OBU On Board Unit
RSU Road Side Unit
DLL Data Link Layer
x = Type of testing BV Valid Behaviour Test
BI Invalid Behaviour Test
= sequential number >0 = sequential number
NOTE: All tests specified in the present document are data link layer tests. The term in the TP identifier is
used to have a consistent TP reference covering also the tests on the application layer provided in a separte
part of this multi-part deliverable.

5.1.3 Sources of TP definitions
All TPs are specified according to the base standard ES 200 674-1 [1].
5.1.4 General reference
All references in the test purposes, if not stated differently, are indicating clauses of the base standard ES 200 674-1 [1].
All references to PICS are indicating tables in TS 102 708-1-1 [2].

5.1.5 General conditions
For all TPs related to OBUs the following pre-conditions shall apply, if not defined differently for a specific TP:
• The OBU shall be ready for communication, i.e. it shall not be in sleep mode and all boot processes shall be
finalized.
Additional pre-conditions may apply for specific TPs.
5.1.6 Default PICS selection
For all TPs related to OBUs the following PICS selections shall apply in addition to those specified for a specific TP:
• Tables A.1/1, A.4/3 and A.4/9 of the PICS [2] is implicitly selected for all TPs.
For all TPs retaled to RSUs the following PICS selections shall apply in addition to those specified for a specific TP:
• Tables A.1/2, A.4/2, A.4/8 and A.5/1 of the PICS [2] is implicitly selected for all TPs.
Further PICS selections may apply as specified for a specific TP. These only give hints on the major properties to be
tested, as the base standard [1] does not contain selectable options.
5.2 Test purposes for on-board units
5.2.1 Valid behaviour tests
TP/OBU/DLL/BV/01 Verify that the IUT can reply to requests providing proper values in the LLC address field
Reference: Clauses 10.9.1, 10.4.1 and 10.4.2
PICS Selection: Table A.3/1
TC reference:
Initial condition:
Stimulus and Expected Behaviour:
1) Tester sends a frame to the IUT upon which a reply is expected.
2) Verify that the tester receives the expected reply with the LLC address field of the received frame containing the
same value as the LLC address field transmitted in step 1).

TP/OBU/DLL/BV/02 Verify that the IUT can receive downlink frames of maximum allowed length as defined by
N2
Reference: Clause 10.2.2.4
PICS Selection: Table A.5/4
TC reference:
Initial condition:
Stimulus and Expected Behaviour:
1) Tester sends downlink frame containing any sequence of PDUs in such a way that the number of octets in the frame
equals the maximum number as defined by N2.
2) Verify IUT properly confirms the requests send in step 1) by a corresponding uplink frame.

TP/OBU/DLL/BV/03 Verify that the IUT implements correctly the timing constraint T for uplink windows
umax
Reference: Clause 10.9.2
PICS Selection: Table A.5/3
TC reference:
Initial condition:
Stimulus and Expected Behaviour:
1) Tester sends a frame to the IUT containing a valid request upon which reception of a frame of maximum length from
the IUT is expected.
2) Verify that the tester receives the expected reply from the IUT. Tester records time T from the end of the last bit
umax
of the closing flag of the frame containing the request from the tester until t
