分析了两个源-目的地对和一个中继站的网络中协作的容量增益。中继解码两个消息的情况下被认为是。可实现的速率区域推导和评估高斯信道。采用简单的编码方案，其不包括编码器和/或中继器处的速率分割。所得到的结果表明，在某些情况下，从干扰转发的收益：中继最佳分裂发送所需的消息和干扰之间的功率。因此，中继站使用其功率中的一些功率来促进目的地节点处的干扰消除，而不是仅转发消息。
Capacity gains from cooperation in a network with two source-destination pairs and a relay are analyzed. Scenarios in which the relay decodes both messages are considered. An achievable rate region is derived and evaluated for Gaussian channels. A simple encoding scheme is employed that does not include rate-splitting at the encoders and/or the relay. The obtained results demonstrate the gains from interference forwarding in certain scenarios: the relay optimally splits its power between sending the desired message and the interference. Thus, instead of only message forwarding, the relay uses some of its power to facilitate interference cancelation at the destination node.
