Inter Cell Interference Coordination (ICIC) in 4G

ICIC is a multi-cell Radio Resource Management (RRM) function that takes into account information from multiple cells (e.g., the resource usage status and traffic load situation) and manages radio resources such that inter-cell interference is minimized.

ICIC (Inter Cell Interference Co-ordination) is a multi-cell Radio Resource Management (RRM) function that takes into account information from multiple cells (e.g., the resource usage status and traffic load situation) and manages radio resources such that inter-cell interference is minimized.

ICIC is defined in LTE to support soft frequency reuse.

Messages are exchanged in real time between eNBs over the X2 interface for the ICIC function. These messages are triggered by certain thresholds and broadcast to neighbor cells. The neighbor cells can do interference-aware scheduling to lower or avoid interference in the network near cell edge with that neighboring cell.
