摘要 在家庭基站与宏基站共存的异质网络中,混合访问既能减少传输干扰,又能提高整网吞吐量,因此是最理想的访问机制。但是,如果没有一定的激励机制,家庭基站的私人所有者不会向宏基站用户无偿提供访问权限,阻碍了混合访问的实现。在本文中,我们提出了基于反向拍卖模型的家庭基站混合访问机制,在该模型中,宏基站运营商向家庭基站所有者购买访问权限,从而实现混合访问。我们的主要目标是实现社会福利最优化并且保证拍卖的真实性。由于多个家庭基站的覆盖范围可能重叠,我们将访问权限的覆盖范围细化。首先,我们设计了基于VCG拍卖模型的反向拍卖模型,该模型最大化了社会福利并且最小化了宏基站运营商的支出。由于基于VCG的反向拍卖模型复杂度过高,我们提出了两个同样满足真实性的拍卖模型,即拓展次高价拍卖模型和次优拍卖模型。我们进一步考虑了家庭基站所有者对不同覆盖地点的访问权限的要价不同的情况,设计了相应的拍卖机制。

Abstract: In the two-tier macro-femto heterogeneous network, hybrid access is regarded as the most ideal access control approach to mitigating macro-femto cross-tier interference and enhancing overall network performance. However, the implementation of hybrid access is hindered by a lack of incentive market mechanism to motivate private femtocell owners to offer access permissions to macro users. In this paper, we propose a reverse auction framework for access permission transaction between a macrocell operator and multiple femtocell owners to promote hybrid access. Our goal is to maximize social welfare while guaranteeing the truthfulness of the auction. Since the coverage of multiple femtocells may overlap, we partition each cell to adjust the granularity of access permission availability. We first propose a Vickery-Clarke-Grove (VCG)-based mechanism, which costs the least among all auction mechanisms that produce maximum social welfare. As the VCG mechanism is too time-consuming, we propose two alternative truthful mechanisms, namely, generalized secondprice and suboptimal mechanism. We further extend the auction framework to the scenario where femtocell owners have heterogeneous valuations for access permissions in different locations.
