    • Base stations may include a plurality of antenna ports adapted to communicatively couple to respective remote antenna units. A base station simulcast controller module may be coupled with each antenna port, and may be adapted to transmit downlink transmissions over a plurality of remote antenna units, with two or more of the remote antenna units simulcasting downlink transmissions as a simulcasting group. In response to one or more obtained network traffic parameters, the base station simulcast controller module may modify the simulcasting group to include at least one different remote antenna unit. Methods operational on base station may include transmitting downlink transmissions over a plurality of remote antenna units, where two or more of the remote antenna units form a simulcasting group. The simulcasting group can be modified to include at least one different remote antenna unit in response to one or more obtained network traffic parameters.

    • A wireless communication network uses backhaul negotiation based upon static and dynamic resource assignment on jamming graphs. Static reuse factor design methods including fractional frequency reuse (FFR) are addressed. The jamming graph is used to summarize the interfering relationship between transmitters (nodes in the jamming graph). Negotiation-based algorithm is used to arrive at a static resource assignment so that a large reuse factor can be achieved while jamming scenario can be avoided. As a result of such algorithm, each transmitter is assigned some resources, over which traffic transmission can be done instantaneously to reduce the packet delay for short packets. Based on the result of static resource negotiation algorithm, a dynamic resource algorithm can be run, such that the resources assigned to different nodes can be share in a bursty traffic scenario to further reduce packet delay for larger packet size cases, while jamming be also avoided.
    • 无线通信网络使用基于干扰图上的静态和动态资源分配的回程协商。 包括分数频率复用(FFR)在内的静态重用因子设计方法得到了解决。 干扰图用于总结发射机(干扰图中的节点)之间的干扰关系。 使用基于谈判的算法来获得静态资源分配,从而可以避免干扰情况下实现大的重用因子。 作为这种算法的结果,每个发射机被分配一些资源,可以通过该资源瞬时完成业务传输以减少短分组的分组延迟。 基于静态资源协商算法的结果,可以运行动态资源算法,使得分配给不同节点的资源可以在突发流量场景中共享,以进一步减小较大分组大小情况下的分组延迟,同时也避免干扰 。
