Efficient Temporal-Spatial Spectrum Sharing through Voluntary Exchange

该项目的目标是开发更有效和更灵活的无线电频谱接入。通常，无线电频谱由FCC分配给商业和非商业用户，这些用户可以被认为是“主要用户”。“这样的用户可能不需要一直使用频谱。这导致了机会主义地接入频谱的“次要用户”的存在。然而，这样的次使用会给其他次用户和主用户带来干扰。此外，主要用户几乎没有动机允许这种类型的二次使用，因为对他们没有任何好处，只有风险。为了鼓励频谱共享和提高频谱效率，重要的是要有一种机制或解决方案概念，为主要用户和次要用户创建正确的激励。然而，在频谱带的销售或交换中涉及显著的通信成本以及限制。因此，通过自愿交换的频谱共享被提出来解决这些挑战，以实现高效的频谱接入。本研究将探讨频谱共享模式对一级用户、二级用户及社会的影响，并探讨包括货币交换和易货交易在内的自愿性频谱共享机制，以促进一级用户和二级用户之间的频谱共享，并在频谱共享模式中考虑通信成本和信息交换的限制。共享频谱和提高频谱效率是立法者和频谱监管机构当前的优先事项，这可以通过国家宽带计划（2010）、PCAST关于联邦政府和非政府用户之间共享频谱的报告（2012）、2012年频谱法案、2013年频谱法案和2014年频谱法案来证明。以及关于这一主题的两份主席备忘录（2010年和2013年）。显然，开发和应用适当的经济理论来促进更多的频谱共享机会是一个理想的结果，对所有利益相关者，包括商业宽带提供商，公共安全，国土安全和国防都有着广泛的影响。

The goal of this project is to develop more efficient and flexible access to radio spectrum. Typically radio spectrum bands are allocated by the FCC to commercial and noncommercial users who can be thought of as "primary users." Such a user may not need to utilize the spectrum all of the time. This has led to the existence of "secondary users" who access the spectrum opportunistically. However, such secondary usage can bring interference to other secondary users and primary users. Furthermore, primary users have little motivation to permit this type of secondary use as there is no benefit to them and only risk. To encourage spectrum sharing and enhance spectrum efficiency, it is important to have a mechanism or solution concept that creates the correct incentives for both primary and secondary users. However, there are significant communication costs as well as limitations involved in the sale or exchange of spectrum bands. Therefore, spectrum sharing through voluntary exchange is proposed to address these challenges for efficient spectrum access. The research project outlined here will determine which type of spectrum sharing mechanisms would be better for primary users, secondary users, and for society.More specifically, voluntary exchange mechanisms including monetary exchange and barter are examined to promote spectrum sharing between primary and secondary users where both the communication costs and constraints for information exchange are reflected in the spectrum sharing models. Moreover, new ways to avoid interference for users located in different regions are examined to further enhance spectrum efficiency.Sharing spectrum and improving spectrum efficiency are current priorities of lawmakers and spectrum regulators, as evidenced through the National Broadband Plan (2010), the PCAST report on sharing spectrum between the federal government and non-government users (2012), the Spectrum Act of 2012, and two presidential memoranda on the topic (2010 and 2013). Clearly, development and application of appropriate economic theories to foster more opportunities for spectrum sharing is a desirable outcome with significant broader impact to all stakeholders, including commercial broadband providers, public safety, homeland security, and national defense.
