Synopsis

I. Introduction

    In March 2021, the Federal Communications Commission announced a 
planned auction of new flexible-use licenses in the 3.45-3.55 GHz band 
(Auction 110). See Auction of Flexible-Use Service Licenses in the 
3.45-3.55 GHz Band for Next-Generation Wireless Services; Comment 
Sought on Competitive Bidding Procedures for Auction 110, AU Docket No. 
21-62, Public Notice, 2021 WL 1086298 (2021); see also Facilitating 
Shared Use in the 3100-3550 MHz Band, WT Docket No. 19-348, Second 
Report and Order, Order on Reconsideration, and Order of Proposed 
Modification, 2021 WL 1086295 (2021) (3.45 GHz Band 2d R&O). Auction 
110 will offer 4,060 new licenses throughout the contiguous United 
States, subject to cooperative sharing requirements in certain, defined 
areas where and when federal incumbents \1\ require continued access to 
the band. The Commission, NTIA, and the Department of Defense (DoD) are 
working collaboratively towards these goals. By this Public Notice, the 
Commission, through WTB, and NTIA, provide (i) information for 
potential bidders in the 3.45 GHz Service auction and (ii) guidance to 
the ultimate 3.45 GHz Service licensees and the affected federal 
incumbents regarding coordination procedures for shared use of the 3.45 
GHz band. The joint nature of this Public Notice reflects the 
intersecting jurisdictions of the Commission (which administers 
spectrum for non-federal uses) and NTIA (which administers spectrum for 
federal uses) in the radio spectrum, including in this band.
---------------------------------------------------------------------------

    \1\ References to federal incumbents in this Public Notice refer 
to the individual military departments with which 3.45 GHz Service 
licensees will negotiate coordination agreements.
---------------------------------------------------------------------------

    The Public Notice proceeds as follows. In section II, we provide

[[Page 38082]]

general background information about federal/non-federal coordination 
in the areas of the 3.45 GHz band in which federal incumbents have 
spectrum assignments. In section III, we provide information and 
guidance on the overall coordination process in areas subject to 
coordination, consistent with the requirements of the 3.45 GHz Band 2d 
R&O, including informal pre-coordination discussions and the formal 
process of submitting coordination requests and receiving results from 
relevant federal incumbents.

II. Background

    3.45 GHz Band 2d R&O. On March 17, 2021, the Commission adopted 
rules governing flexible use of spectrum in the 3.45-3.55 GHz band, 
thereby making 100 megahertz of mid-band spectrum available for 
flexible-use wireless services, including 5G. Under the Commission's 
framework for the band, developed in collaboration with the Executive 
Branch, non-federal systems generally will have unencumbered use of the 
entire band across the contiguous United States and, with limited 
exceptions, federal systems operating in the band may not cause harmful 
interference to non-federal operations in the band. In limited 
circumstances and in locations where current incumbent federal systems 
will remain in the band, however, non-federal systems will not be 
entitled to protection against harmful interference from federal 
operations (and restrictions may be placed on non-federal operations). 
These exceptions will occur only in geographic areas specifically 
identified as Cooperative Planning Areas and Periodic Use Areas.
    Cooperative Planning Areas and Periodic Use Areas. Cooperative 
Planning Areas and Periodic Use Areas are defined in US Footnote US431B 
to the U.S. Table of Frequency Allocations. US431B also identifies the 
boundaries of each of the 33 Cooperative Planning Areas, as well as the 
23 overlapping Periodic Use Areas, by reference to either a point and 
radius or a series of coordinates (which create a polygon). 3.45 GHz 
Service licensees must successfully coordinate their operations with 
federal incumbent(s) before commencing operation in any Cooperative 
Planning Area or Periodic Use Area. Several statutory provisions 
encourage negotiation, coordination, and spectrum sharing between non-
federal users and federal entities.\2\ Beyond simply coordinating 
within those areas, federal and non-federal operators are encouraged to 
enter into mutually acceptable operator-to-operator agreements. Such 
agreements may permit more extensive flexible use within Cooperative 
Planning and Periodic Use Areas by adopting a technical approach that 
mitigates the interference risk to federal operations. The parameters 
of Cooperative Planning and Periodic Use Areas defined in US431B are 
the default, but in practice should be a starting point for 
negotiations between flexible-use licensees and federal incumbents; 
more expansive use by the flexible-use licensee can be agreed to in 
areas and under circumstances or parameters acceptable to the federal 
incumbent.
---------------------------------------------------------------------------

    \2\ See NTIA Manual, Annex O (Relocation or Sharing by Federal 
Government Stations in Support of Reallocation) Sec.  O.5.1 
(Negotiation and Coordination with Non-Federal Users), citing, e.g., 
47 U.S.C. 923(g)(3)(A)(iv)(II) and (g)(3)(B)(i), 923(h)(2)(F); see 
also id. at Sec.  928(d)(3)(B)(i)(II).
---------------------------------------------------------------------------

    Fort Bragg and Little Rock. As noted in the 3.45 GHz Band 2d R&O, 
in all but two of the Cooperative Planning and Periodic Use Areas, 3.45 
GHz Service licensees must coordinate with federal incumbents across 
all 100 megahertz of spectrum within the areas. In the Fort Bragg, 
North Carolina, Cooperative Planning Area and Periodic Use Area, in 
contrast, licensees will only need to coordinate in the lower 40 
megahertz of the band, i.e., 3450-3490 MHz, because the federal 
incumbent will only use the lower 40 megahertz of the band in this 
area, leaving the upper 60 megahertz unencumbered and available for 
full-power, flexible-use operations in accordance with the rules 
adopted herein. Thus, licensees in the upper portion of the band, i.e., 
3490-3550 MHz, need not coordinate with the federal incumbent in the 
Fort Bragg areas. In the Little Rock, Arkansas Cooperative Planning 
Area, for approximately the first 12 months following the close of the 
auction for this band, licensees will have to coordinate with the 
federal incumbent across all 100 megahertz of the spectrum within the 
Little Rock area. After this time period, however, licensees will only 
need to coordinate in the lower 40 megahertz of the band in the Little 
Rock area, as the federal incumbent will vacate the upper 60 megahertz, 
i.e., 3490-3550 MHz, by that time.\3\
---------------------------------------------------------------------------

    \3\ The DoD will provide notice to licensee(s) via their portal 
account(s) and will post a notice on its portal front page, and NTIA 
will post a similar notice on its 3450-3550 MHz web page (https://www.ntia.gov/category/3450-3550-mhz).
---------------------------------------------------------------------------

    Information on Incumbent Federal Operations. Information about 
incumbent federal operations is generally available through the 
affected federal incumbents' Transition Plans. By way of background, 
federal incumbents in the 3.45 GHz band were required to develop and 
submit Transition Plans to implement relocation or sharing arrangements 
and affected federal incumbents have done so. Transition Plans contain 
information on these federal systems, including the frequencies used, 
emission bandwidth, system use, geographic service area, authorized 
radius of operation, and estimated timelines and costs for relocation 
or sharing. Affected federal incumbents are permitted to redact from 
the publicly released Transition Plans classified national security 
information and ``other information for which there is a legal basis 
for nondisclosure and the public disclosure of which would be 
detrimental to national security, homeland security, or public safety 
or would jeopardize a law enforcement investigation.'' \4\ NTIA expects 
to publish the publicly available Transition Plans on its website no 
later than June 7, 2021.\5\ Other publicly available information from 
NTIA regarding the 3.45 GHz band is also available through the same 
website.
---------------------------------------------------------------------------

    \4\ See 47 U.S.C. 923(h)(7). Each federal entity that requested 
pre-auction funds attested in its Transition Plan that it will, 
during the transition period, make available to a non-federal user 
with appropriate security clearances any classified information 
regarding the relocation process, on a need-to-know basis, to assist 
the non-federal user in the relocation process with the eligible 
federal entity or other eligible federal entities. Accord 47 U.S.C. 
928(d)(3)(B)(ii)(4); see also NTIA Manual of Regulations and 
Procedures for Federal Radio Frequency Management (NTIA Manual), 
Annex O at Sec. Sec.  O.4.1 ] 3, O.6.1, and at Appendix: Common 
Format for Transition Plans, Tab B.
    \5\ See 47 U.S.C. 923(h)(5) (requiring NTIA to publish approved 
plans on its website no later than 120 days before the start of the 
auction). See https://www.ntia.gov/category/3450-3550-mhz.
---------------------------------------------------------------------------

    The 3.45 GHz band currently is used by the DoD for high- and low-
powered radar systems on a variety of platforms in the 3 GHz band, 
including fixed, mobile, shipborne, and airborne operations, along with 
testing infrastructure and training operations. Generally, incumbent 
federal operations in 3.45 GHz band include the following categories of 
systems:

 High-powered shipborne radars
 Lower power airborne radars
 Lower power ground-based radars
 Testing infrastructure
 Training operations

    For information on the incumbent federal operations, please see the 
Transition Plans and DoD's Workbook and associated file(s) once they 
are published on NTIA's website.\6\
---------------------------------------------------------------------------

    \6\ https://www.ntia.gov/category/3450-3550-mhz.
---------------------------------------------------------------------------

    Below, we describe the specific coordination requirements set forth 
in the 3.45 GHz Band 2d R&O and we provide guidance regarding how such 
requirements might be addressed.

[[Page 38083]]

III. Coordination Process Guidance

    Before a 3.45 GHz Service licensee commences operations in a 
Cooperative Planning Area or Periodic Use Area, it must first 
successfully coordinate with the federal incumbent(s) associated with 
that area. The purpose of coordination is to facilitate shared use of 
the band in these specified areas and during specified time periods. 
The coordination procedures outlined here will apply to all 3.45 GHz 
Service licensees seeking to operate in a Cooperative Planning Area or 
Periodic Use Area, unless the 3.45 GHz Service licensee and the federal 
incumbent(s) have reached a mutually agreeable coordination arrangement 
that provides otherwise. Such arrangements could, for example, document 
specific notification and activation procedures. Moreover, additional 
coordination requirements, procedures, and scenarios may be developed, 
consistent with any Administrative Procedure Act or other legal 
requirement that may apply, in future public notices, specific 
operator-to-operator agreements, or other mechanisms. We expect 3.45 
GHz Service licensees and federal incumbents to negotiate in good faith 
throughout the coordination process (e.g., sharing information about 
their respective systems and communicating results to facilitate 
commercial use \7\ of the band).
---------------------------------------------------------------------------

    \7\ References to commercial use in this Public Notice refer to 
non-federal, primary, flexible use of the 3.45 GHz band and do not 
preclude use of the band for private mobile radio services. See 47 
U.S.C. 332(d)(3); 47 CFR 20.3.
---------------------------------------------------------------------------

A. Contact

    The DoD will create an online portal through which any 3.45 GHz 
Service licensee that intends to commence operations within a 
Cooperative Planning Area or Periodic Use Area must initiate formal 
coordination requests for its relevant systems within the associated 
area.

B. Informal Discussions

    Before a 3.45 GHz Service licensee submits a formal coordination 
request, it may share draft proposals or request that federal incumbent 
coordination staff discuss draft coordination proposals. These 
discussions are voluntary, informal, and non-binding and can begin at 
any time after the conclusion of the auction. 3.45 GHz Service 
licensees may discuss their proposed deployments and seek guidance from 
the federal incumbent(s) on appropriate measures to ensure that 
electromagnetic compatibility (EMC) analyses undertaken by the federal 
incumbent(s) produce positive results. 3.45 GHz Service licensees and 
federal representatives also may develop an analysis methodology that 
reflects the characteristics of licensees' proposed deployments and the 
federal incumbents' operation. These discussions also can involve 
developing a process for identification and resolution of harmful 
interference.
    Informal discussions are intended to allow federal incumbents and 
3.45 GHz Service licensees to share information about their respective 
system designs and to identify potential issues before a formal 
coordination request will be submitted through the DoD's online portal. 
The federal incumbents involved, unless they specify otherwise in 
writing, would not be committing to any final determination regarding 
the outcome of the formal coordination. We strongly encourage parties 
to use informal, non-binding discussions to minimize or resolve basic 
methodological issues upfront, before having the 3.45 GHz Service 
licensees submit formal coordination requests. The DoD will provide a 
single point of contact on NTIA's website upon conclusion of the 
auction through which a licensee may initiate informal discussions.

C. Formal Coordination

    We provide guidance for the formal coordination process below. This 
description is general, and the process may differ between federal 
incumbents and is subject to modification by the federal incumbents and 
licensees as agreed to on an operator-to-operator basis. We expect and 
encourage federal incumbents and 3.45 GHz Service licensees to engage 
in good faith coordination.
1. Initiation
    Coordination shall be initiated by the 3.45 GHz Service licensee by 
formally requesting access to operate within a Cooperative Planning 
Area or Periodic Use Area. This request must be made directly through 
the DoD's online portal. The 3.45 GHz Service licensee must set up its 
portal account and, once established, the 3.45 GHz Service licensee 
will receive a user guide and training on the use of the portal.
2. Timing
    No formal coordination for nine (9) months. As set forth in the 
3.45 GHz Band 2d R&O, unless a 3.45 GHz Service licensee and the 
relevant federal incumbent otherwise agree, no formal coordination 
requests may be submitted until nine (9) months after the date of the 
auction closing Public Notice. 3.45 GHz Service licensees may request 
informal discussions during this nine-month time period as described 
above in section B.
    Timing Generally and Affirmative Concurrence. Nine (9) months after 
the close of the auction, federal incumbents are expected to timely 
review and respond to formal coordination requests. We encourage 
licensees and incumbents, through informal discussions, to serialize 
formal coordination requests as appropriate to avoid an overwhelming 
influx of coordination requests at the conclusion of the nine (9) month 
quiet period. For example, a licensee holding licenses in multiple 
Cooperative Planning or Periodic Use Areas could provide a prioritized 
list of coordination requests to be acted upon by the federal 
incumbent(s). This informal information exchange may aid the licensee 
in creating its prioritized list of deployments, which is required as 
part of its formal coordination request. We also encourage licensees 
and federal incumbents to discuss, as appropriate, extended review 
timelines to the extent that the incumbents' coordination resources are 
exhausted due to a large number of requests within a short time period 
after the quiet period. This will help maximize the quick and efficient 
review of coordination requests.
    When a licensee submits a formal request, the federal point of 
contact will affirmatively acknowledge receipt of the request within 
five (5) calendar days after the date of submission. Within ten (10) 
calendar days after the submission date, federal incumbent staff will 
notify the 3.45 GHz Service licensee that the request is complete or 
incomplete. Unless the federal incumbent finds the request incomplete 
or the federal incumbent and 3.45 GHz Service licensee agree to a 
different timeline, the federal response (the results letter discussed 
below) is due within sixty (60) calendar days after the deadline for 
the notice of completeness.
    Unless otherwise agreed to in writing, the requirement to reach a 
coordination arrangement is satisfied only by obtaining the affirmative 
concurrence of the relevant federal incumbent(s) via the portal. This 
requirement is not satisfied by omission.
3. Submission Information
    To submit a formal coordination request, the 3.45 GHz Service 
licensee must include information about the technical characteristics 
for its base stations and associated mobile units relevant to operation 
within the Cooperative Planning Area or Periodic Use Area. This 
information should be

[[Page 38084]]

provided in accordance with the instructions provided in the DoD's 
online portal user's guide. The types of specific information, 
including the likely data fields in the portal, include basic technical 
operating parameters (e.g., system technology, mobile EIRP, frequency 
block, channel bandwidth, site name, latitude, and longitude). The 
portal will accept uploaded attachments that include narratives that 
explain area-wide deployments.
    3.45 GHz Service licensees must prioritize their deployments in the 
Cooperative Planning Area or Periodic Use Area for each federal 
incumbent when submitting a formal coordination request. If a licensee 
seeks to coordinate with multiple systems or multiple locations of 
operation controlled by one federal incumbent, it must specify the 
order in which it prefers the federal incumbent process the request 
(i.e., the order of systems or geographic locations).
4. Notice of Complete or Incomplete Request
    Once a licensee submits a formal coordination request, the relevant 
federal incumbent's coordination staff will review the data to ensure 
that it is in the proper format and contains the proper content. 
Federal incumbent coordination staff will notify the 3.45 GHz Service 
licensee within ten (10) calendar days through the portal that its 
formal coordination request is complete or incomplete. If the federal 
incumbent coordination staff finds a request to be incomplete, it must 
identify the information that the licensee must provide in as much 
specificity as possible. We expect that parties will work 
collaboratively to achieve completeness in a timely manner.
5. Coordination Analysis
    As noted above, unless a timely notice of incomplete application is 
sent to the 3.45 GHz Service licensee (or the parties agree to 
different a timeline), the clock for the federal response begins to run 
on the deadline for the notice of completeness. The federal response is 
due within sixty (60) calendar days thereafter, unless the 3.45 GHz 
Service licensee agrees otherwise. During these sixty (60) days, the 
federal incumbent will coordinate with appropriate internal units, 
complete EMC analysis, and post the 3.45 GHz Service concurrence, 
partial concurrence with operating conditions, or denial. Each federal 
incumbent is responsible for ensuring that it completes its internal, 
multi-level review in a timely manner. Federal incumbents are 
encouraged, through their designated internal coordination point of 
contact or through other means, to ask any questions and discuss any 
issues that arise with the 3.45 GHz Service licensee.
    Once the designated federal incumbent coordinator completes its 
analysis pursuant to the formal coordination request, the 3.45 GHz 
Service licensee and the relevant federal incumbent field offices will 
be notified automatically when a results letter is posted by the 
federal user in the portal. The result of a coordination request will 
be concurrence, partial concurrence with operating conditions that 
specify the terms in which the licensee may begin operations, or denial 
of the request. Because of the sensitive nature of the data involved in 
much of the EMC analysis, the results letter may not present details of 
the analysis, the federal frequency assignments affected, or timelines. 
If a federal incumbent does not provide a results letter within the 
sixty (60) day-deadline, or within the timeline otherwise agreed to by 
the 3.45 GHz Service licensee, the 3.45 GHz Service licensee may 
contact NTIA for assistance.
    Once a results letter is posted by the federal incumbent 
coordinator in the portal, we strongly encourage the 3.45 GHz Service 
licensee to acknowledge receipt of the letter via the portal. If no 
affirmative acknowledgement is made via the portal, the 3.45 GHz 
Service licensee should be aware that the federal incumbent coordinator 
may close out the coordination request in the portal 60 days after 
posting the results letter. Notwithstanding the 3.45 GHz Service 
licensee's acknowledgement of receipt, if a 3.45 GHz Service licensee 
has questions about the result, it may contact the federal incumbent 
coordinator to propose network design modifications to help address EMC 
issues raised in the results letter. The federal incumbent coordinator 
may, where feasible, review technical proposals from the 3.45 GHz 
Service licensee to relieve or resolve a denial, partial concurrence or 
any operating condition contained in the results letter. Once the 3.45 
GHz Service licensee has revised its network design, it must resubmit a 
new formal coordination request, and the 3.45 GHz Service formal 
coordination process will begin again.
    We stress again the benefits of informal discussions among 3.45 GHz 
Service licensees and federal incumbents, including during the formal 
coordination process. While in many cases, federal incumbent staff may 
be unable to provide specific information about the protected federal 
operations and are not responsible for designing the 3.45 GHz Service 
system, they may offer some suggestions on how to address or mitigate 
the issue, given the limited information that can be made available on 
some federal systems. If the parties agree that informal discussions 
would be helpful, the sixty (60)-day clock will be paused so the 
federal incumbents are not forced to formally decline or condition the 
pending, formal coordination request within the sixty (60)-day 
deadline.
6. Streamlined Coordination Process for High-Power Radar Sites
    An optional streamlined framework is available to meet the 
coordination requirement associated with some of the high-power radar 
facilities identified with an asterisk (*) in footnote US431B of 47 CFR 
2.106 as set forth in Appendix A. The list of sites for which 
streamlined coordination applies will be posted on NTIA's website at 
the same time as the Transition Plans. 3.45 GHz Service licensees 
requesting coordination for a Cooperative Planning Area have a 
streamlined option set forth in Appendix B of this Public Notice in the 
form of a template coordination agreement. Once a 3.45 GHz Service 
licensee completes and delivers (via the DoD portal) a signed copy of 
the template agreement set forth in Appendix B, and the federal 
incumbent countersigns, the Commission and NTIA will deem the 
coordination requirement satisfied for the 3.45 GHz Service licenses 
and Cooperative Planning Areas listed in Table A of the agreement. 
Federal incumbents will complete and countersign a template agreement 
within thirty (30) calendar days of receiving one signed by the 3.45 
GHz Service licensee. Exchange of information during execution of these 
coordination agreements may be facilitated by use of the DoD portal 
described in section C.1 above.
7. Periodic Use Areas Operator-to-Operator Agreements
    In accordance with the 3.45 GHz Band 2d R&O, 3.45 GHz Service 
licensees and federal incumbents are expected to develop operator-to-
operator agreements to define notification processes and timelines 
before commencement of federal operations within a Periodic Use Area. 
The operator-to-operator agreement could, for example, specify the 
notification process, content, and timelines (i.e., the starting and 
ending dates and times of such use). The agreements also may specify 
that the 3.45 GHz Service licensee and the federal incumbent may use a 
scheduling tool to complete the notification process

[[Page 38085]]

or agree to technical limitations to commercial operations (e.g., 
reduced power levels and antenna pointing angles) in lieu of a 
notification process.
    Upon receipt of a coordination request that includes a Periodic Use 
Area, the DoD will contact the licensee via the portal to schedule a 
time to discuss establishing an operator-to-operator agreement. Due to 
the complexities of the negotiations, operator-to-operator agreements 
may not be finalized during the 60-day coordination analysis process. 
Both parties are expected to negotiate in good faith.
    In addition, an Incumbent Informing Capability (IIC) could be 
developed to facilitate coordination within the Periodic Use Areas. The 
IIC concept is a time- and location-based spectrum sharing uniform 
approach that would enable federal agencies to submit information, 
reliably and securely, about when and where they would be employing 
certain frequencies. This scheduling information would inform a 
licensee, allowing commercial network providers to adjust operations in 
near real time and avoid harmful interference. The goal is to enable 
efficient, secure, and reliable spectrum sharing between new commercial 
networks and the incumbent federal systems. As part of the DoD's funded 
Transition Plan, the DoD will develop an Automated Sharing Coordination 
System (ASCS) which could be used to provide notification of the 
activation of Periodic Use Areas by DoD incumbents. All use of these 
capabilities is dependent upon the operator-to-operator agreements.

D. Dispute Resolution

    Disputes generally--during coordination or regarding a sharing 
agreement. If disputes arise during the coordination process, we 
strongly encourage parties to negotiate in good faith to resolve them. 
If a 3.45 GHz Service licensee believes that a federal incumbent is not 
negotiating in good faith, the licensee may seek the assistance of NTIA 
or it can inform the Commission. If a federal incumbent believes that a 
3.45 GHz Service licensee is not negotiating in good faith, it must 
nonetheless timely respond to a formal request and would have the 
option to seek assistance from NTIA or the Commission. We encourage 
parties to enter into operator-to-operator agreements that have dispute 
resolution provisions for any or all possible disputes. If a dispute 
arises between an incumbent federal incumbent and a 3.45 GHz Service 
licensee over an operator-to-operator agreement, provisions calling for 
informal negotiation, mediation, or non-binding arbitration between the 
parties will help to clearly define and narrow the issues for formal 
agency resolution by NTIA, the Commission, or both agencies acting 
jointly, as applicable.
    Certain disputes for which the law and NTIA rules allow parties to 
request a dispute resolution board. If a dispute arises between a 
federal entity \8\ and a 3.45 GHz Service licensee regarding the 
execution, timing, or cost of the approved Transition Plan, the law 
provides that either the federal entity or the non-federal user may 
request that NTIA establish a dispute resolution board to resolve the 
dispute. See Section 113(i) of the NTIA Organization Act, as amended 
(47 U.S.C. 923(i)). NTIA has adopted regulations that govern the 
working of any dispute resolution boards established by NTIA. See 47 
CFR part 301. Those regulations cover matters related to the workings 
of a board, including the content of any request to establish a board, 
the associated procedures for convening it, and the dispute resolution 
process itself.\9\
---------------------------------------------------------------------------

    \8\ We note that the dispute resolution process detailed in 47 
U.S.C. 923(i) references certain disputes that may arise between a 
``Federal entity'' and a non-federal user. For purposes of this 
Public Notice, such a ``Federal entity'' is the same as a federal 
incumbent.
    \9\ Membership of a dispute resolution board shall be composed 
of a representative of OMB, NTIA, and the FCC, each appointed by the 
head of his or her respective agency. The OMB representative serves 
as the Chair of any board. With respect to the resolution of any 
disputes that may arise, the law and NTIA's rules require a board to 
meet simultaneously with representatives of the federal entity and 
the non-federal user to discuss the dispute.
---------------------------------------------------------------------------

    The Middle Class Tax Relief and Job Creation Act of 2012 requires a 
board to rule on the dispute within thirty (30) days after a party has 
requested NTIA to convene the board. As stated in Annex O, ``[t]he 
statute's 30-day deadline for responding to formal dispute resolution 
requests could possibly impact a board's ability to convene, meet with 
the parties, and adequately address complex cases.'' NTIA Manual, Annex 
O at Sec.  O.5.2 ] 3. See 47 CFR 301.200(a)(2). At the same time, 
however, the statute and Annex O encourage cooperation to assure timely 
transitions between federal and non-federal use of the spectrum. If and 
when differences surface among federal and non-federal parties, NTIA's 
rules require the parties to make good faith efforts to solve these 
problems on an informal basis before submitting a formal request to 
establish a dispute resolution board. Informal negotiation, mediation, 
or non-binding arbitration between the parties will help to clearly 
define and narrow the issues needed to be brought into the formal 
dispute resolution process.
    The scope of a dispute resolution request and, consequently, a 
board's decision, are limited by law and NTIA's regulations to matters 
``regarding the execution, timing, or cost of the transition plan 
submitted by the Federal entity.'' 47 U.S.C. 923(i)(1). The statute 
authorizes a dispute resolution board to make binding decisions on such 
matters that can be appealed to the United States Court of Appeals for 
the District of Columbia Circuit. Id. Sec.  923(i)(7). Under NTIA's 
rules, the dispute resolution board must also ensure that its decision 
does not have a detrimental impact on any national security, law 
enforcement, or public safety function made known to the board by an 
agency. See 47 CFR 301.220(b); see also NTIA Manual, Annex O at Sec.  
O.5.2 ] 4. To fulfill that obligation, the board may request additional 
written submissions from an agency regarding the impact of such a 
decision on the agency's operations, services, or functions.

E. Other Coordination Issues

    Sharing of Sensitive and Classified Information. The DoD is 
establishing a mechanism for the sharing of sensitive and classified 
information. NTIA expects that further details regarding this process 
will be posted on NTIA's website soon.
    Interference Resolution Process. The introduction of non-federal, 
flexible-use licenses increases the possibility that harmful 
interference will occur between new entrants and incumbent federal 
users. As reflected in the new footnote US431B to the Table of 
Frequency Allocations, 3.45 GHz Service licensees in both types of 
coordination areas (Cooperative Planning Areas and Periodic Use Areas) 
must not cause harmful interference to federal users, and federal users 
should minimize the operational effect that they have on non-federal 
users. Furthermore, footnote US431B also provides that 3.45 GHz Service 
licensees cannot claim interference protection within the coordination 
areas, absent an operator-to-operator agreement that specifies 
otherwise. In addition, 3.45 GHz Service licensees may be required to 
``avoid, where possible, interference and potential damage to the non-
Federal operators' systems.'' 47 CFR 2.106 US431B(a). In instances of 
identified harmful interference occurring between a federal user and a 
3.45 GHz Service licensee not addressed by the coordination procedures 
or operator agreements, the 3.45 GHz Service licensee shall first 
attempt to resolve the

[[Page 38086]]

interference directly. If that effort is unsuccessful, the 3.45 GHz 
Service licensee, if adversely affected, may escalate the matter to the 
Commission.
    Future Workshops and Workbooks. The DoD Transition Plans to be 
published on NTIA's website will provide important information to 
prospective auction participants. They will be redacted to remove 
sensitive information as guided by statute. To supplement its 
Transition Plans, the DoD will be providing a ``Workbook'' that will 
offer additional publicly releasable information about its operations 
and coordination expectations and will be posted on NTIA's website in 
conjunction with the redacted Transition Plans. The Workbook will be in 
the form of an Excel spreadsheet containing additional information 
about where the DoD anticipates its operations will encumber census 
tracts inside of the Cooperative Planning Areas and Periodic Use Areas 
based on frequency block and commercial tower height. Its structure 
will be similar to the AWS-3 DoD Workbook. As noted in both the NTIA 
letter to the FCC and the 3.45 GHz Band 2d R&O, the Cooperative 
Planning Areas and Periodic Use Areas are based on 100-meter commercial 
towers. The DoD will be providing information on anticipated encumbered 
census tracts based on both 100-meter and 100-foot commercial towers on 
a frequency block basis. Additionally, the DoD will be providing 
anticipated power density level curves for the high-power radar 
locations via the mechanism for sharing sensitive information described 
in Section E of this Public Notice.
    The DoD is also planning to host a public workshop in the July 2021 
timeframe to discuss its Transition Plans and the Workbook and answer 
questions. Further details regarding the exact date, location, and 
registration information will be made available on NTIA's website in 
the near future.

Appendix A

47 CFR 2.106 US431B

    US431B The band 3450-3550 MHz is allocated on a primary basis to 
the Federal radiolocation service and to the non-Federal fixed and 
mobile, except aeronautical mobile, services on a nationwide basis. 
Federal operations in the band 3450-3550 MHz shall not cause harmful 
interference to non-Federal operations, except under the following 
circumstances.
    (a) Cooperative Planning Areas. Cooperative Planning Areas 
(CPAs) are geographic locations in which non-Federal operations 
shall coordinate with Federal systems in the band to deploy non-
Federal operations in a manner that shall not cause harmful 
interference to Federal systems operating in the band. In addition, 
operators of non-Federal stations may be required to modify their 
operations (e.g., reduce power, filtering, adjust antenna pointing 
angles, shielding, etc.) to protect Federal operations against 
harmful interference and to avoid, where possible, interference and 
potential damage to the non-Federal operators' systems. In these 
areas, non-Federal operations may not claim interference protection 
from Federal systems. Federal and non-Federal operators may reach 
mutually acceptable operator-to-operator agreements to permit more 
extensive non-Federal use by identifying and mutually agreeing upon 
a technical approach that mitigates the interference risk to Federal 
operations. To the extent possible, Federal use in CPAs will be 
chosen to minimize operational impact on non-Federal users. The 
table in paragraph (d) identifies the locations of CPAs, including, 
for information, those with high powered Federal operations. CPAs 
may also be Periodic Use Areas as described below. Coordination 
between Federal users and non-Federal licensees in CPAs shall be 
consistent with rules and procedures established by the FCC and 
NTIA.
    (b) Periodic Use Areas. Periodic Use Areas (PUAs) are geographic 
locations in which non-Federal operations in the band shall not 
cause harmful interference to Federal systems operating in the band 
for episodic periods. During these times and in these areas, Federal 
users will require interference protection from non-Federal 
operations. Operators of non-Federal stations may be required to 
temporarily modify their operations (e.g., reduce power, filtering, 
adjust antenna pointing angles, shielding, etc.) to protect Federal 
operations from harmful interference, which may include restrictions 
on non-Federal stations' ability to radiate at certain locations 
during specific periods of time. During such episodic use, non-
Federal users in PUAs must alter their operations to avoid harmful 
interference to Federal systems' temporary use of the band, and 
during such times, non-Federal operations may not claim interference 
protection from Federal systems. Federal and non-Federal operators 
may reach mutually acceptable operator-to-operator agreements such 
that a Federal operator may not need to activate a PUA if a mutually 
agreeable technical approach mitigates the interference risk to 
Federal operations. To the extent possible, Federal use in PUAs will 
be chosen to minimize operational impact on non-Federal users. 
Coordination between Federal users and non-Federal licensees in PUAs 
shall be consistent with rules and procedures established by the FCC 
and NTIA. While all PUAs are co-located with CPAs, the exact 
geographic area used during periodic use may differ from the co-
located CPA. The geographic locations of PUAs are identified in the 
table in paragraph (d). Restrictions and authorizations for the CPAs 
remain in effect during periodic use unless specifically relieved in 
the coordination process.
    (c) For the CPA at Little Rock, AR, after approximately 12 
months from the close of the auction, non-Federal operations shall 
coordinate with Federal systems in only the 3450-3490 MHz band 
segment and the 3490-3550 MHz band segment will be available for 
non-federal use without coordination. At Fort Bragg, NC, non-Federal 
operations shall coordinate with Federal systems in only the 3450-
3490 MHz band segment.
    (d) The following table identifies the coordinates for the 
location of each CPA and PUA. An area may be represented as either a 
polygon made up of several corresponding coordinates or a circle 
represented by a center point and a radius. If a CPA has a 
corresponding PUA, the PUA coordinates are provided. A location 
marked with an asterisk (*) indicates a high-power federal 
radiolocation facility. If a location includes a Shipboard 
Electronic Systems Evaluation Facility (SESEF) attached to a 
homeport, it specifies the associated SESEF.

Appendix B

Streamlined Coordination Option--Template Agreement Coordination 
Agreement Between [3.45 GHz Service Licensee] (``3.45 GHz Service 
Licensee'') and [Federal Incumbent] (``Federal Incumbent'')

1. Introduction

    This Coordination Agreement is between [Insert name of 3.45 GHz 
Service Licensee](hereinafter referred to as the ``3.45 GHz Service 
Licensee''), and [Insert name of Federal Incumbent] (hereinafter 
referred to as the ``Federal Incumbent''), and sets forth the terms 
and conditions for their operations in the 3.45-3.55 GHz band.

2. Acknowledgement of Regulations

    All 3.45 GHz Service licensees must accept interference caused 
by the operation of Federal Incumbent's [high-powered radar] site(s) 
and shall protect Federal Agency's high-powered radar operations, as 
required by 47 CFR 27.1602 and 47 CFR 2.106, footnote US431B. The 
parties agree that within the Cooperative Planning Areas listed in 
Table A below, the 3.45 GHz Service Licensee will coordinate with 
the Federal Incumbent by notifying the Federal Incumbent of the 3.45 
GHz Service Licensee's intent to commence flexible-use service 
within the Cooperative Planning Area and submitting the additional 
information as listed in Section 4 below, prior to use of the 
spectrum. In cases where interference from high-powered radar 
site(s) results in 3.45 GHz Service Licensee customer complaints, 
the 3.45 GHz Service Licensee will take actions to address those 
complaints and employ mitigation methods to reduce the likelihood of 
them reoccurring.

      Table A--Description of License(s) Subject to This Agreement

4. 3.45 GHz Service Licensee Notification to Federal Incumbent

    As required by Section 2 above, the 3.45 GHz Service Licensee 
will provide to the Federal Incumbent the following information:
     3.45 GHz Service Licensee's deployment plans in the 
Cooperative Planning Area;
     Methods the 3.45 GHz Service Licensee plans to use to 
mitigate interference into its base station receivers, and an 
explanation of how the methods will mitigate interference from high-
powered radar(s) and prevent any impaired consumer experience;
     Contact information for the 3.45 GHz Service Licensee's 
network operation center and local engineering staff; and
     Assurance that the 3.45 GHz Service Licensee will 
satisfy its obligations to provide safety of life services (i.e., 
911) on bands other than the 3.45 GHz band in the Cooperative 
Planning Area as needed.

5. Continuing Communications Between 3.45 GHz Service Licensee and 
Federal Incumbent

    The parties shall:
     Address with each other, when the need first arises, 
any consumer complaints associated with the 3.45 GHz Service 
Licensee's operations near Federal high-powered radar(s). This may 
include the 3.45 GHz Service Licensee's development of external 
communication regarding reports of interference or interruption of 
service using the 3.45 GHz band. This external communication should 
reflect the acknowledgement of regulations in Section 2 above; and
     Meet annually to discuss network deployments, current 
and future technologies, interference mitigation techniques, 
consumer experiences, and other relevant topics necessary to help 
the Federal Incumbent understand the evolving use of the band, and 
its impact upon 3.45 GHz Service operations;
     The above additional interactions can be initiated by 
either POC listed above.

6. Substantial Changes to High-Powered Radar Operations or 3.45 GHz 
Service Deployments

    If either party plans operations that are substantially 
different from the [original] concept of operations, the differences 
must be discussed during the annual meeting required by Section 5 
above unless an immediate meeting is required to mitigate new and/or 
unexpected interference.

7. Sensitive/Proprietary Information

    All information exchanged under this Coordination Agreement is 
considered sensitive/proprietary. Any exchange of information 
associated with this Coordination Agreement should be marked as 
sensitive/proprietary.

8. Successful Coordination

    Execution of and compliance with all terms of this Coordination 
Agreement meets the regulatory requirement for successful 
coordination in 47 CFR 27.1603.
