    摘要： A method and device for determining whether to send a measurement report to a serving cell and determining when an inter-cell coordination procedure is likely to achieve coordination gain are disclosed. According to one aspect, a method includes performing received signal quality measurements of the serving cell and a plurality of neighboring cells. The method also includes calculating a UE metric based on the received signal quality measurements of a plurality of interfering cells and based on a scaling parameter. The method further includes comparing the calculated UE metric to a threshold to determine whether to send the measurement report to the serving cell.

    摘要： A node including processing circuitry including a processor, and a memory, the memory containing instructions that, when executed by the processor, configure the processor to: determine a cluster of a plurality of cells, assign at least one ZP CSI-RS configuration to each of the plurality of cells of the cluster, assign to each cell in the plurality of cells of the cluster a respective NZP CSI-RS configuration in which each of the NZP CSI-RS configurations assigned to respective cells in the cluster partially overlapping the at least one ZP CSI-RS configuration, and cause a first cell of the plurality of cells of the cluster to transmit, within a subframe, based on the at least one ZP CSI-RS configuration and the NZP CSI-RS configuration assigned to the first cell.

    摘要： A method and system for determining whether to apply an inter-cell coordination procedure for a UE in the presence of inter-cell interference from cells, the cells including a serving cell and a plurality of interfering cells, are disclosed. According to one aspect, a method includes receiving measurements of uplink signal quality of the UE from the cells. The method also includes calculating a combined metric based on the received uplink signal quality measurements. The combined metric is compared to a serving cell threshold to determine whether to implement the inter-cell coordination procedure.
