Licensed Shared Access (LSA) is a complementary solution allowing Mobile Network Operators (MNOs) to use another incumbents frequency spectrum after obtaining a proper license from the regulator.

Using auctions to allocate those LSA-type licenses is a natural approach toward an efficient use of spectrum, by controlling the incentives for MNOs to declare their true valuation for the spectrum and allocating it to those who value it the most. A specificity of LSA licenses lies in the interactions among buyers, due to possibly overlapping coverage areas, this allows for allocating the same spectrum to several MNOs.

In this paper, we review the existing mechanisms taking into account such radio interference constraints, propose new ones, and compare their performance. We show how to increase the revenue, while maintaining truthful-telling, of all-or-nothing auction mechanisms by introducing a reserve price per bidder. We also investigate extensions of those mechanisms, namely when the management of interference among base stations is more subtle than partitioning base stations into groups of non-interfering base stations. For each mechanism, we show how to optimize a trade-off between expected fairness, expected revenue and expected efficiency by carefully working with groups and reserve prices. Simulations suggests that the extension of those mechanisms may lead to increase an indicator combining allocation fairness, social welfare and seller’s revenue by more than 20% compared to the ones without the extension.

5G许可共享访问:选择哪种拍卖机制?

许可共享访问(LSA)是一种补充解决方案,允许移动网络运营商(MNO)在获得监管机构的适当许可后,使用另一个现有频谱。

使用拍卖来分配那些LSA类型的许可证是一种有效利用频谱的自然方法,方法是控制MNO宣布其频谱真实估值的动机,并将其分配给最重视频谱的人。LSA许可证的特殊性在于购买者之间的相互作用,这可能是因为覆盖区域可能重叠,这允许将同一频谱分配给多个MNO。

在本文中,我们将考虑到此类无线电干扰约束条件,回顾现有机制,提出新的机制,并比较其性能。我们展示了如何通过引入每位竞标者的底价来增加收入,同时又能保持如实算盘的拍卖机制。我们还研究了这些机制的扩展,即当基站之间的干扰管理比将基站划分为无干扰基站组时更加微妙的时候。对于每种机制,我们都展示了如何通过与团队和底价进行仔细合作来在预期公平性,预期收入和预期效率之间优化取舍。模拟表明,这些机制的扩展可能会导致增加结合分配公平性的指标,
