摘要:
PROBLEM TO BE SOLVED: To provide systems and methodologies that facilitate interference measurement and reporting in a network multiple-in-multiple-out (N-MIMO) communication system.SOLUTION: A network device can measure and report interference corresponding to network nodes other than a designated set of nodes. Interference reports can additionally identify dominant interfering nodes, correlation between transmit antennas of the respective nodes, or the like. The interference reports are combined with per-node channel information to manage coordination and scheduling across the respective network nodes. Interference from a network node can be measured by observing reference and/or synchronization signals from the network node. Each non-interfering network node can define null pilot intervals in which transmission is silenced or otherwise reduced. Loading information broadcasted by interfering network nodes can be identified and utilized in connection with interference calculation.

要解决的问题:提供有助于网络多输入多输出(N-MIMO)通信系统中的干扰测量和报告的系统和方法。解决方案:网络设备可以测量和报告与除非 一组指定的节点。 干扰报告可另外识别主要干扰节点,相应节点的发射天线之间的相关性等。 干扰报告与每节点信道信息相结合,以管理各个网络节点之间的协调和调度。 可以通过观察来自网络节点的参考和/或同步信号来测量来自网络节点的干扰。 每个非干扰网络节点可以定义其中传输被静音或以其他方式减少的空导频间隔。 干扰网络节点广播的加载信息可以与干扰计算结合起来进行识别和利用。
