    Workshop 2 read-ahead material. Please review this material before the workshop to understand key NRDZ issues and topics, which have also informed the agenda for this workshop.

DAY 1: Spectrum coexistence tutorials. November 16, 2021. 12:55 - 4PM EDT

    Day 1 will feature several tutorials on the state-of-the-art in spectrum sharing from experts in the passive and active communities.
    12:55 - 1:00. Welcome and overview from the organizers.
      Mariya Zheleva, Chris Anderson, Chris DePree, Joel Johnson and Mustafa Aksoy
    1:00 - 2:20. Tutorial 1: Examples of Methods Used to Protect Incumbents in 3.5 GHz CBRS and 6 GHz AFC with Relevance to Passive/Active Spectrum Sharing
    2:20 - 2:30. Break
    2:30 - 4:00. Tutorial 2: Spectrum management for radio astronomy -- VLA telescope scheduling

    DAY 2: Main workshop day. November 17, 2021. 12:30-5:20PM EDT

      12:30-12:40 - Welcome and overview from the organizers.
        Mariya Zheleva, Chris Anderson, Chris De Pree, Joel Johnson and Mustafa Aksoy
      12:40-1:00 - Thoughts from NSF
      1:00-2:00 - Fireside chat and QnA: Now that there is pie on the table, how do we divide it?

      2:00-3:10 - Panel: Building the coffee shop in the library.
        This panel will bring together experts across spectrum sharing technologies and application domains. The panel will present several grand challenges to NRDZ spectrum sharing that emerged from our community efforts over the past year. Panelists will offer their expert opinion on approaches to tackle these challenges and open problems that will require a collaborative approach.

        Moderated by Liese van Zee, Department of Astronomy, Indiana University – Bloomington.

      3:10-3:20 - Break
      3:20-3:50 - QnA with panelists
      3:50-4:50 - Grand challenges sprints
        The sprints will be facilitated by pairs of panelists. Participants will work collaboratively to leverage their knowledge in existing spectrum sharing towards solving grand challenges in shared spectrum access for NRDZs.
        • Policy sprint -- build a policy framework for NRDZ. There are two extremes for a potential policy framework including (i) no licensing procedures; all unlicensed, show up, plug into the system and do whatever experiments you need in the zone; and (ii) fully-fleshed FCC+NTIA licensing. Where does an NRDZ need to be on this spectrum to allow quick experimentation with stakeholder protections? How do we realize this?
        • Monitoring sprint -- conceptualize a spectrum monitoring system for NRDZ that can support (i) the wide range of target frequencies (30MHz - 200GHz and potentially into THz); (ii) the vastly different sensitivity levels required by participating technologies (i.e. 120dB difference between radio astronomy and active communications); and (iii) the differences in the geographical footprint of NRDZ technologies?
        • Experiment management sprint -- conceptualize an experiment management system to allocate NRDZ resources to experiments considering all stakeholders needs. Develop a schema for information exchange across disparate stakeholders in support of NRDZ resource allocation.
      4:50-5:15 - Sprints review and retrospective
        Each sprint team will be asked to provide a brief update on the outcomes of their discussion.
      5:15-5:20 - Closing remarks
