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效应。尽管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。现有的ICI处理方法大大降低了网络的数据传输速率，而新的ICI处理方法往往缺乏可实现性，因此，协作多点（CoMP）技术是否应该被纳入未来的标准中成为一个热门话题。网络中基站的协作保证了数据速率的大的增益。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，它可能会影响这些速率。该建议的重点是ICI缓解策略之间的利益和成本的最佳权衡的合作。在一个框架，特别是设计用于比较合作和非合作技术，其中包括合作的缺点，应找到最佳的非合作策略，并应最大可能的合作收益的特点。应确定有益的合作类型，最后，应找到新的合作方法，提供拟议的折衷办法。
