论文摘要
本文分析了多路复用收益（MG），以同时传输延迟敏感和耐延迟数据而不是干涉网络。在考虑的模型中，只有延迟耐耐剂数据才能从协调的多点传输或接收技术中获利，因为必须在不进一步延迟的情况下传输延迟敏感的数据。延迟耐受性数据的传输也受到延迟约束的约束，但是在延迟敏感的数据上，该数据的严格程度不如延迟约束。提出了不同的编码方案，并针对Wyner的线性对称网络以及Wyner的二维六边形网络来表征用于延迟敏感和容忍数据的相应MG对，具有和没有部门化。对于Wyner的线性对称，也建立了信息理论匡威，并且只要合作率足够大，或者对延迟敏感的毫克很小或中等时，则证明是准确的。这些结果表明，在Wyner的对称线性网络以及对于足够大的合作率上，可以实现最大的延迟敏感数据的MG，而无需惩罚延迟敏感和耐受性数据的最大总和。 Wyner的Hexagonal网络仅适用于具有部门化的模型，也有类似的结论。在没有部门化的模型中，每当一个人坚持阳性延迟敏感的毫克时，就会发生惩罚。
This paper analyzes the multiplexing gains (MG) for simultaneous transmission of delay-sensitive and delay-tolerant data over interference networks. In the considered model, only delay-tolerant data can profit from coordinated multipoint (CoMP) transmission or reception techniques, because delay-sensitive data has to be transmitted without further delay. Transmission of delay-tolerant data is also subject to a delay constraint, which is however less stringent than the one on delay-sensitive data. Different coding schemes are proposed, and the corresponding MG pairs for delay-sensitive and delay-tolerant data are characterized for Wyner's linear symmetric network and for Wyner's two-dimensional hexagonal network with and without sectorization. For Wyner's linear symmetric also an information-theoretic converse is established and shown to be exact whenever the cooperation rates are sufficiently large or the delay-sensitive MG is small or moderate. These results show that on Wyner's symmetric linear network and for sufficiently large cooperation rates, the largest MG for delay-sensitive data can be achieved without penalizing the maximum sum-MG of both delay-sensitive and delay-tolerant data. A similar conclusion holds for Wyner's hexagonal network only for the model with sectorization. In the model without sectorization, a penalty in sum-MG is incurred whenever one insists on a positive delay-sensitive MG.
