通过利用无线信道的广播特性，协作传输可以极大地提高通信系统的性能。以往关于协作传输资源分配的工作大多是基于集中控制的。本文提出了信噪比拍卖和功率拍卖两种份额拍卖机制来分布式协调用户间的资源分配。证明了拍卖结果的存在性、唯一性和有效性。特别是，SNR拍卖导致了用户之间的公平资源分配，而功率拍卖实现了接近高效分配的解决方案。
Cooperative transmission can greatly improve communication system performance by taking advantage of the broadcast nature of wireless channels. Most previous work on resource allocation for cooperation transmission is based on centralized control. In this paper, we propose two share auction mechanisms, the SNR auction and the power auction, to distributively coordinate the resource allocation among users. We prove the existence, uniqueness and effectiveness of the auction results. In particular, the SNR auction leads to a fair resource allocation among users, and the power auction achieves a solution that is close to the efficient allocation.
