宏蜂窝、微蜂窝、局域网/家庭基站相结合的分层次覆盖的异构网络是移动通信网络发展的一个重要方向。异构网络中形成的重叠覆盖，干扰情况比较复杂，协作多点技术是一种行之有效的消除干扰的办法。然而，异构网络的复杂性使得多点协作消除干扰方案及其资源分配技术不能直接延用同构网络的结果，有必要探寻适合异构网络中协作多点资源分配的新技术。为此，项目组围绕未来无线通信系统的需求，充分利用时间、频率、空间等各种无线资源，在对异构网络中协作多点系统性能分析的基础上，形成异构无线网络中协作多点MIMO-OFDMA自适应高效的联合传输技术方案。并通过对系统进行多系统组合、多基站联合、多尺度拟合、多目标融合、多场景综合的资源分配技术的研究，寻找复杂度与性能折衷、网络性能与公平性适度的资源分配算法，提高整个网络无线资源利用率。

The coveraged hierarchically heterogeneous networks with the macroc/micro/femto base stations(BSs) and local area networks(LAN) are very significant in the mobile communication network. The coordinated multiple point (CoMP) transmission can eliminate the interference in heterogeneous networks with overlapping coverage and complex interference. However, the CoMP transmission and resource allocation algorithms in homogenous network aren't fit to heterogeneous networks since there is more complexity in it. So it's necessary to search after the CoMP resource allocation algorithms for heterogeneous networks. Therefore in view of the requirement of wireless communication system in the future, making full use of the various wireless resources (time, frequency, space etc. for example), based on the performance analysis of CoMP in heterogeneous networks, the joint CoMP MIMO-OFDMA adaptive transmission scheme for heterogeneous wireless networks is proposed. And resource allocation algorithms are also proposed by study on the system with multi-system multi-BS multi-scale multi-objective multi-situation. The proposed resource allocation algorithms, which take into account the balance of complexity and performance, the balance of network performance and fairness, can improve the wireless resources utilization rate of overall network.
