未来几年，无处不在的超高速连接将在很大程度上通过增加基站和频谱聚合来实现。由此产生的非常密集的网络（DenseNets）将面临许多技术挑战。在其他方面，这种干扰就像一个具有新意义的老熟人。事实上，攻击者和受害者的干扰条件和作用在很大程度上取决于密度和场景。为了说明这一点，比较了不同3GPP模拟场景和东京更不规则和密集部署的下行干扰统计数据。向DenseNets的演进为下行干扰合作技术的进一步发展提供了新的机遇。对LTE和LTE- advanced中的各种机制进行了回顾。一些技术试图以积极主动的方式预测未来，而另一些技术只是对已识别的干扰问题做出反应。作为一个例子，我们提出了在DenseNet中应用时域和频域小单元干扰协调的两种算法。
The promise of ubiquitous and super-fast connectivity for the upcoming years will be in large part fulfilled by the addition of base stations and spectral aggregation. The resulting very dense networks (DenseNets) will face a number of technical challenges. Among others, the interference emerges as an old acquaintance with new significance. As a matter of fact, the interference conditions and the role of aggressor and victim depend to a large extent on the density and the scenario. To illustrate this, downlink interference statistics for different 3GPP simulation scenarios and a more irregular and dense deployment in Tokyo are compared. Evolution to DenseNets offers new opportunities for further development of downlink interference cooperation techniques. Various mechanisms in LTE and LTE-Advanced are revisited. Some techniques try to anticipate the future in a proactive way, whereas others simply react to an identified interference problem. As an example, we propose two algorithms to apply time domain and frequency domain small cell interference coordination in a DenseNet.
