6. IEEE P1609.3Rev Proposed elements of revision to 1609.3-2016
formal clarification of informal guidance notes (technical clarifications) developed since December 2016
keeping in mind to preserve backwards compatibility with 2016 version
alignment with terminology discussions
cleanup ASN.1 in Annexes J, K, L
some updates to related info, e.g., security profile template
media independence and interoperability
service primitive diagrams are media specific, channel information and WAVE information elements (transmit power, data rate, priority, etc.) are PHY specific
significant level of effort required to make changes
WG agreed to develop annex for media independence and interoperability, draft annex to be ready for November meeting

7. OmniAir Test Working Group
1609 WG requested information regarding changes proposed to ™-2016
Making ASN.1 representation of WSA, WSM, and WAVE Information Element format normative
Use of WME MIBs
OmniAir Recommendations
Based on information from past plug tests and device providers
Use ASN.1 in Annexes J, K ,and L as the normative specification and maintain text/figures to facilitate explanation. If a conflict is found, ASN.1 takes precedence.
Do not change version identifier for WSM or WSA (current set as 3) when the standard change to use ASN.1 as normative.
Continue to maintain MIB for and keep implementation of the WME MIB in devices as optional.

8. IEEE P1609.4Cor
WG agreed to progressing corrigendum PAR for IEEE
retain backward compatibility
include errata, guidance notes, and other corrections identified since publication
For Revision
consider developing annex to address media independence and interoperability similar to proposal for revision of
revision PAR submission in 2019

9. IEEE P Rev
Create process and procedures for requesting, allocating, and maintaining a register of Provide Service Identifier (PSID), considerations include:
IEEE Registration Authority Committee (RAC) Policy, Terms of Reference, and Conventions
IEEE 1609 WG PSID sub-group (SG) structure, composition, roles and responsibilities, part of RAC process (proposed)
Initial Sponsor ballot closed February 20, met 75% return, comment resolution before April meeting, recirculation ballot planned
Participation of an IEEE RAC expert and ISO TC204 WG1 Convener during recent WG meetings provided good exchange of information regarding ISO proposal to establish an Registration Authority and IEEE RA practices

10. IEEE P Rev
Changes in referenced international standards will require updating references and terminology
Proposal for revision pending user requirements for US-based organizations, may include
revision to be able to use the radio in the car as a transponder with different media
to be able to use security and SCMS described in IEEE
PAR for revision to be considered in 2019
Message sets and data sets to be developed in SAE DSRC Technical Committee

11. IEEE P1609.0D14
Revision of WAVE - Architecture, an overview and relationships among the family of 1609 WAVE standards
Completed comment resolution and Sponsor Ballot re-circulations
Submitted for approval
Anticipate publication April 2019
Good reading to understand the 1609 family of standards, after approval

12. Data Distribution Mechanism
Scenario
An arbitrarily large amount of data
To be distributed over a limited-capacity channel
To a potentially large number of recipients
With intermittent connectivity
Mechanism needs to:
Allow for discovery of updates to data of interest
Allow for identification of target groups of devices
Use medium efficiently
i.e., can be used in situations where unicast is not possible due to channel limitations
Mechanism could be used as “enhanced fragmentation” mechanism for WSMP

13. Data Distribution Mechanism(1)
Explore existing solutions that address some or all of these needs
WG Discussion
Distribution mechanism addresses a need that is not addressed by other mechanisms being considered for inclusion in the CV environment
Could be a key enabling technology for deployment, especially DSRC-based deployment
Could allow peer-to-peer distribution of cache information in C-V2X setting when devices are out of cell coverage due to lack of coverage or lapse in subscription

14. Data Distribution Mechanism(2)
Proposed Next Step – Form Study Group
Validate that this problem is worth solving
Analyze existing NYC protocol and propose improvements/generalizations
Security
Analyze how this cache-and-distribute distribution mechanism would fit into existing data discovery and subscription mechanisms
MQTT, AMQP, DDS, …
Produce PAR for standard for WG approval, or a determination that no such PAR is necessary
Produce significant amounts of design material that could be used to generate draft standard
Goal: Report at June meeting and have standard ready for review at meeting following

15. Other VT/ITS Projects
In VTS, VT/ITS is accountable for a number of projects
1609 family of standards
P1920.2, Standard for Vehicle to Vehicle Communications for Unmanned Aircraft System
P2020, Standard for Automotive System Image Quality
P , Standard Technical Specifications of a DC Quick Charger for Use with Electric Vehicles
P2690, Standard for Charging Network Management Protocol for Electric Vehicle Charging Systems; There is an emerging need in global markets for a formal standard for communication between EVCS and external device/services management systems. Such a protocol standard will provide a basis for increasing functionality and interoperability between EVCS and charging services networks
P7001, Standard for Transparency of Autonomous Systems; This standard is needed to set out expectations for transparency of AS, to the range of stakeholders outlined above, in order to build trust, provide the means to assure safety, and allow accountability and traceability. The standard will articulate a range of levels of transparency.
The VTS Rail Transit Standards Committee is very active

16. Liaison Activities
SAE DSRC TC (message sets and data dictionary, performance requirements)
Developing SSP for J2945/5, Service Specific Permissions and Security Guidelines for Connected Vehicle Applications
SAE C-V2X TC (upper layer protocol development)
joint participants

contributions developing requirements for registration authority (ISO ) required by ISO Directives
PSID and ITS-AID registry joint informal management
Support for ITS station security functions (ISO 21177)

Observer, WG17, Urban ITS
ETSI TC-ITS
IEEE SA, Partner SDO

17. Registry and Registration Authority Determination
Ken Vaughn, ISO TC204 WG1 Convener, requested IEEE 1609 WG to name two liaisons to coordinate developing requirements for an ITS (C-ITS) Registration Authority and registry process described in work item ISO
On-going effort to attain consensus on the draft of ISO nearing completion with discussions on next WG1 meeting, April 2, 2019
Goal is for ISO to sign an agreement with an RA based on the requirements from ISO and expectation is for publication in Q4/2019
May be later date because of mandatory review and comment period for DIS and scheduled ISO TC204 plenary
Out-reach to known entities that have ITS-related registries planned by the HTG7 C-RR
Continued discussion during ISO TC204 WG1 meeting, April 23, 2019
