Synopsis. By this Public Notice (PN), the Public Safety and Homeland Security Bureau (Bureau) seeks comment on the filings from the respective Departments of Transportation of the State of Florida and State of Georgia, and State of Maryland State Highway Administration, each requesting a waiver of the Commission's rules to operate roadside units (RSUs) with cellular vehicle to everything (C-V2X)-based technology in the upper 30 megahertz (5.895-5.925 GHz) portion of the 5.850-5.925 GHz (5.9 GHz) band under its Part 90 intelligent transportation system (ITS) license. These waiver requests seek operating authority for C-V2X through the streamlined waiver process described by the Commission in its November 20, 2020 5.9 GHz First Report and Order and the guidance that the Bureau, in conjunction with the Wireless Telecommunications Bureau (the Bureaus), provided in a subsequent Public Notice, as directed by the Commission.

Guidance PN. Based on the decisions in the 5.9 GHz First Report and Order, and until the Commission renders a decision on the rule changes proposed in the Further Notice of Proposed Rulemaking, the Commission stated that it will permit any existing or future part 90 intelligent transportation system (ITS) licensee to operate C-V2X-based roadside units in the 5.895-5.925 GHz band within their geographic licensing areas by requesting and obtaining a waiver of the Commission's rules, subject to specific conditions. On August 6, 2021, the Bureaus jointly issued the Guidance PN detailing the process for such waiver applicants, and providing additional information regarding further waivers that may be required for requesting early deployment of certain other C-V2X operations, and the equipment certification process for C-V2X equipment.

Streamlined Waiver Process for Part 90 Licensees. In the Guidance PN, the Bureaus stated inter alia, that in order to receive streamlined consideration of a waiver request, consistent with Section 1.925 of the Commission's rules, applicants would need to provide the following certifications:

(1) a certification that there are no existing ITS licensees authorized to operate within the same geographic area in which the waiver applicant seeks to operate, OR certification that the waiver applicant has coordinated with every existing ITS licensee licensed (in whole or part) within that same geographic area to ensure that the waiver applicant's C-V2X-based roadside unit operations will not interfere with any Dedicated Short Range Communications (DSRC)-based roadside units operating in the 5.895-5.925 GHz band;

(2) a certification that the waiver applicant's C-V2X operations will comply with the existing technical rules ( e.g., including, but not limited to, power and out-of-band emission limits) for DSRC-based technologies other than the portion of the current rules requiring use of DSRC-based technologies;

(3) a certification that the applicant's operations will be revised to the extent necessary to comply with any final rules that the Commission adopts for C-V2X operations; and

(4) a certification that the applicant's C-V2X operations will be limited to transportation and vehicle safety-related communications.

General Waiver Process for Part 90 Licensees. Regarding licensees unable to satisfy the streamlined waiver process, in the Guidance PN, the Bureaus stated that:

“If an ITS waiver applicant that seeks authority to operate C-V2X-based roadside units or on-board units in the 5.895-5.925 GHz band is unable to comply with the existing ITS technical rules found in 47 CFR 90.371-90.383 or 47 CFR 95.3167-95.3189, respectively, they should include in their general waiver request the certifications from the streamlined waiver process outlined in this PN that they are unable to meet, the specific existing rules that they are unable to comply with, along with a specific proposal of the technical specifications they seek to use instead, and an explanation of why a waiver is warranted under Section 1.925. To facilitate granting of qualifying waiver requests, and in light of the alternate technical specifications proposed in their waiver, we would generally expect the ITS waiver applicant to include a demonstration showing that their requested waiver would not cause a greater potential for interference to other users operating in the 5.895-5.925 GHz band than DSRC-based operations in this band, and otherwise to address how the public interest would be served by such a waiver under Section 1.925. Based on the proposed change in technical parameters, the waiver request should also address any conditions ( e.g., coordination zone radius, per 47 CFR 90.371(b)) necessary to protect Federal Government Relocation Services.”

Equipment Certification Guidance. The Bureaus' Guidance PN discussed the need for additional waivers of the FCC's equipment authorization rules to allow for C-V2X on-board units. As noted in the Guidance PN, the applicant for equipment certification should identify the specific technical requirements that the C-V2X equipment would meet. In the Guidance PN, the Bureaus said:

“The applicant for equipment certification should identify the specific technical requirements that the C-V2X equipment would meet, and explain how those specific technical requirements would be consistent with the associated waiver(s) granted for operation of C-V2X systems in the 5.895-5.925 GHz band. To the extent that the request for waiver of equipment authorization rules to authorize C-V2X-based roadside units or on-board units differs in any respect from the technical rules specified in the Part 90 or Part 95 waiver(s), the application for waiver may require more extensive review, consistent with current practice relating to waiver of equipment authorization rules.”

The Waiver Requests and Supplemental Information. As noted above, the respective state entities each filed an initial request for waiver, and each has subsequently supplemented its request with additional information in support of their requests. Commenters should review each of these requests and supplemental materials for purposes of commenting. Among other things, each state has provided particular technical information on its proposed C-V2X operations. We provide a high-level summary of that information below.

Public Comment on Waivers. Prior to evaluating the merits of the instant requests for waivers, and in order to assist in assessing the requests, the Bureau seeks comment on whether the certifications, as supplemented, in the Waivers are sufficient to allow the Bureau to make a rigorous evaluation of the requests under the streamlined review process. Under the general waiver process, we seek comment on whether the waiver requests as supplemented contain sufficient information to satisfy the additional requirements set forth in the Guidance PN at footnote 10, referenced above, including whether the proposed C-V2X operations would protect others from interference. In addition, we seek comment from manufacturers on equipment authorizations to support the proposed operations in the instant waiver requests.

Procedural Matters. To develop a complete record on the issues presented by this request, the proceeding will be treated, for ex parte purposes, as a “permit-but-disclose” proceeding in accordance with Section 1.1200(a) of the Commission's rules, subject to the requirements under Section 1.1206(b). Parties should file all comments and reply comments in ET Docket No. 19-138 and clearly indicate to which of the three waivers identified in this Public Notice the comments apply ( i.e., Florida Department of Transportation, Georgia Department of Transportation, or Maryland State Highway Administration).
