交替连接拓扑干扰管理中的纠缠解算
Resolving Entanglements in Topological Interference Management with Alternating Connectivity
摘要：
研究了时变信道下三用户干扰有线网络的总容量。由于信道的变化，假设发射机只能跟踪各个节点之间的连接，因此只有网络的（交替）状态是已知的。通过考虑一个特殊的子集的所有可能的状态，我们表明，状态分裂结合联合编码的交替状态需要实现的和容量。关于上界，我们使用一个精灵辅助的方法来显示这个计划的最优性。这突出表明，即使发射机具有严格受限的信道状态信息，也需要更多涉及的发射策略来表征自由度。
英文摘要：
The sum-capacity of a three user interference wired network for time-varying channels is considered. Due to the channel variations, it is assumed that the transmitters are only able to track the connectivity between the individual nodes, thus only the (alternating) state of the network is known. By considering a special subset of all possible states, we show that state splitting combined with joint encoding over the alternating states is required to achieve the sum-capacity. Regarding upper bounds, we use a genie aided approach to show the optimality of this scheme. This highlights that more involved transmit strategies are required for characterizing the degrees of freedom even if the transmitters have heavily restricted channel state information.
