认知网络由主节点和认知（也称为辅助）节点组成，主节点可以优先访问频谱，认知（也称为辅助）节点可以访问频谱，前提是它们在主系统中产生的干扰仍然有限。实际上，这意味着认知终端必须保持在主要接收器周围的区域之外：主要专属区域。本文的重点是该区域的定义以及在主网络约束下认知终端可实现的吞吐量的分析。更准确地说，我们确定了终端传输概率的基本限制，以及在什么条件下该吞吐量对于辅助网络仍然是最佳的（在网络吞吐量意义上）。
A cognitive network consists of primary nodes, which have priority access to the spectrum, and cognitive (also referred to as secondary) nodes, which access the spectrum provided that the interference they generate in the primary system remains limited. In practice, it means that the cognitive terminals must remain outside of a region surrounding the primary receiver: the primary exclusive region. The focus of this paper is on the definition of this region and the analysis of the achievable throughput of cognitive terminals under the constraints imposed by the primary network. More precisely, we establish the fundamental limits of the terminal probability of transmission and under what conditions this throughput can still be optimal (in a network throughput sense) for the secondary network.
