US: SAE LTE-V2X BSM - LTE-V2X WSMP

Description:

This solution is used within Canada and the U.S.. It combines standards associated with US: SAE LTE-V2X BSM with those for V-X: LTE-V2X WSMP. The US: SAE LTE-V2X BSM standards include upper-layer standards required to implement V2V safety information flows over C-V2X. The V-X: LTE-V2X WSMP standards include lower-layer standards that support connectionless, near constant, ultra-low latency vehicle-to-any communications using the WAVE Short Messaging Protocol (WSMP) over 3GPP C-V2X in the 5.9GHz spectrum.

Solution Issues Severity: 13

Solution Issues:

Default	Severity	Name	Type	Description
True	Low	Data not defined in standard format	ITS Info Gap	The definition of data concepts should conform to ISO 14817-1 to promote reuse among ITS.
True	Medium	Overlap of standards	Overlap	Multiple standards have been developed to address this information and it is unclear which standard should be used to address this specific information flow.
True	Medium	Regulatory Permission Needed	Standardization Gap	Deployment of this standard requires regulatory approval, which is currently subject to significant delays.
True	Medium	Uncertainty about trust revocation mechanism	Security Gap	The mechanisms used to prevent bad actors from sending authorized messages is unproven.
True	Medium	Use case not considered in design (medium)	ITS Info Gap	While the indicated standards nominally address the information flow, the design may not meet practical constraints because this particular use case was not the focus of the design effort.
