DUAL THRESHOLD BASED CELL CLUSTERING INTERFERENCE MITIGATION FOR eIMTA

摘要

Methods, systems, and devices are described for interference mitigation between neighboring cells through the use of cell clusters and virtual logical cell clusters. Cells may be added to a cell cluster with a first cell when a level of interference coupling between the first cell and one or more neighboring cells exceeds a first threshold. One or more other cells may be added to a virtual logical cell cluster with the first cell when the level of interference coupling is between a second threshold and the first threshold, the second threshold being less than the first threshold. Interference mitigation between cells of cell clusters and/or virtual logical cell clusters may be performed. Interference mitigation may be accomplished through, for example, coordination of TDD uplink-downlink (UL-DL) configurations for cell clusters and scheduling-dependent interference management (SDIM) for virtual logical cell clusters.

1. A method for wireless communication in a time division duplex (TDD) communication system, comprising:
identifying a plurality of neighboring cells of a first cell; determining a level of interference coupling between the first cell and each identified neighboring cell; adding a first neighboring cell to a cell cluster of the first cell when the level of interference coupling of the first neighboring cell exceeds a first threshold; adding a second neighboring cell to a virtual logical cell cluster when the level of interference coupling of the second neighboring cell is between a second threshold and the first threshold, the second threshold being less than the first threshold; and performing interference mitigation between the first cell and one or more cells in the virtual logical cell cluster.
