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.

小区间干扰 (ICI) 是限制当今蜂窝网络性能的最强影响。尽管 ICI 是由使用同一网络的其他人造设备产生的，但处理 ICI 的最先进方法却无法轻松控制。网络中基站的协作是否会在未来的标准中包含协作多点（CoMP）技术有望带来巨大的收益，这一点受到了热烈的讨论。但是，合作确实如此。并不总是提高系统可能的速率，如果合作所需的信息交换太大，它可以介意这些速率。该提案侧重于在合作的收益和成本之间进行最佳权衡的 ICI 缓解策略。在专门为比较合作和非合作技术（包括合作的缺点）而设计的框架中，应找到最佳的非合作策略，并确定合作的最大可能收益，并最终确定合作的有益类型。 、新的合作方式、应找到提供建议的权衡的方法。
