针对由一个宏小区和多个小小区接入点（SCA）组成的无线网络，提出了一种基于拍卖的波束赋形和用户关联算法。SCA竞争服务于宏小区基站（MBS）用户（MU）。相应的用户关联问题，解决所提出的投标等待拍卖方法。作者考虑了两种情况。在第一种情况下，MBS最初承认它可以同时服务的最大可能的MU集合，然后将剩余的MU拍卖给SCA，SCA除了承诺为自己的主机用户服务之外，还愿意承认访客用户。这一问题通过提出的远期竞价等待拍卖得以解决。在第二种情况下，MBS的目标是尽可能多的MU卸载到SCA，然后接纳最大可能的剩余MU集合。所提出的算法提供了一个解决方案，这是非常接近的最佳解决方案，通过使用一个集中的全球优化。
We propose an auction-based beamforming and user association algorithm for a wireless network consisting of a macrocell and multiple small cell access points (SCAs). The SCAs compete for serving the macrocell base station (MBS) users (MUs). The corresponding user association problem is solved by the proposed bid-wait auction method. The authors considered two scenarios. In the first scenario, the MBS initially admits the largest possible set of MUs that it can serve simultaneously and then auctions off the remaining MUs to the SCAs, who are willing to admit guest users in addition to their commitments to serve their own host users. This problem is solved by the proposed forward bid-wait auction. In the second scenario, the MBS aims to offload as many MUs as possible to the SCAs and then admits the largest possible set of remaining MUs. This is solved by the proposed backward bid-wait auction. The proposed algorithms provide a solution that is very close to the optimum solution obtained by using a centralised global optimisation.
