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

Description:

This solution is used within 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: 16

The severity issue score calculation only includes issues associated with standards that are included by default.

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 Still under development Standardization Gap A draft of the standard has been developed by the working group, but it was still under development at the time this analysis was performed.
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.
