lt in reduced spectral efficiency and cell throughput. ICIC works on the principle wherein the frequency resource is divided into multiple frequency blocks (three blocks or seven blocks). Each cell will have a set of predefined physical resource blocks (PRBs) that are marked as cell center PRBs and another set of PRBs will be marked as cell edge PRBs. Depending on the user location, a UE is either marked as a cell center UE or a cell edge UE, and the PRBs that are marked for cell center usage are provided to the cell center UEs. The PRBs that are marked for cell edge usage are provided to the cell edge UEs by the eNodeB scheduler. Depending on the pattern of usage, care is taken to ensure that no two cells that are adjacent to each other will have the same set of PRBs marked as cell edge. Two UEs from neighboring cells (cell edge users) will not use the same set of PRBs, thereby reducing any interference to each other and improving the cell edge throughput.

ICIC deployment with a reuse coefficient pattern of 3 ICIC may be of two types: static and dynamic. Static ICIC is a basic and simpler approach to implementing the ICIC feature. It is more suitable for cells that are predictable based on the type of traffic and the load distribution. In static ICIC, the parameters are configured during eNodeB commissioning itself. There are no reconfigurations and signaling with peers to negotiate on the resourcing pattern involved in static ICIC. Though it is a simpler approach, it is not necessarily efficient, as the planning does not always cover the different loading conditions and can result in performance degradation. Dynamic ICIC is a more complex approach based on the traffic conditions and cell loading. Dynamic ICIC is more suitable for cells where the cell loads a condition and the user distribution within the cell is
