Abstract  Abstract

Systems and methods are described that facilitate system and method for interference measurement and reporting in network multi-input multi-output (N-MIMO) communication system. As described herein interference of the network node device may measure and report corresponding to the designated node set wherein the designated node set may cooperate to service the device. each of the interference report may additionally identify the main interfering node of the correlation between transmitting antennas of each node and so on. Subsequently each of the interference report can be combined to the channel information of each node so as to manage the scheduling of cooperation and on each network node. as further described herein from a network node of the interference can be observed from the standard of the network node and/or synchronization signals to measure. In order to assist this observation each non-interfering network node can define the null pilot interval in the null pilot interval inhibited or reduced transmission. as additionally described herein load information of each interference broadcast by the network node can combine interference calculation to identify and use.

Systems and methodologies are described herein that facilitate interference measurement and reporting in a network multiple-in-multiple-out (N-MIMO) communication system. As described herein a network device can measure and report interference corresponding to network nodes outside a designated set of nodes that can cooperatively serve the device. Respective interference reports can additionally identify dominant interfering nodes correlation between transmit antennas of respective nodes or the like. Subsequently respective interference reports can be combined with per-node channel information to manage coordination and scheduling across respective network nodes. As further described herein interference from a network node can be measured by observing reference and/or synchronization signals from the network node. To aid such observation respective non-interfering network nodes can define null pilot intervals in which transmission is silenced or otherwise reduced. As additionally described herein loading information broadcasted by respective interfering network nodes can be identified and utilized in connection with interference calculation.
