Interference management in cellular networks with a special focus on the comparison between cooperative and non-cooperative methods

细胞间干扰（ICI）是限制当今蜂窝网络性能的最强影响。虽然ICI是由使用同一网络的其他人造设备产生的，但它不容易控制。最先进的处理ICI的方法大大降低了网络可能的数据速率，而新提出的方法往往缺乏可实现性。讨论了在未来的标准中是否应该包含协作多点技术。网络中基站的合作保证了数据速率的大幅度提高。但是，合作并不总是提高系统的可能速率，如果合作所需的信息交换变得太大，它可能会降低这些速率。本文的重点是在合作的收益和成本之间寻求最佳的权衡，以缓解ICI的策略。在一个特别设计的比较合作与非合作技术的框架中，考虑到合作的缺点，找到最优的非合作策略，并表征出合作的最大可能收益。应确定有益的合作类型，最后，应找到提供所建议的权衡的新合作方法。

Intercell interference (ICI) is the strongest effect limiting the performance of today’s cellular networks. Although, ICI is generated by other man-made devices using the same network, it cannot be controlled easily. State-of-the-art methods handling ICI drastically reduce the possible data rates of the network and new proposed methods often lack implementability.It is discussed intensely, whether cooperative multi-point (CoMP) techniques should be included in future standards. Cooperation of the base stations in a network promises a large gain in data rate. But, cooperation does not always improve the possible rates of a system, it can minder these rates if the required exchange of information for the cooperation becomes too large. This proposal focusses on ICI mitigating strategies with an optimum trade-off between the benefits and the cost of cooperation.In a framework especially designed for comparing cooperative and non-cooperative techniques, which includes the drawbacks of cooperation, optimal non-cooperative strategies shall be found and the maximal possible gain of cooperation shall be characterized. Beneficial types of cooperation shall be identified and, finally, new cooperative methods, which provide the proposed trade-off, shall be found.
