Interference management
Both static and dynamic ICIC algorithmic are supported, being able to define different
operation profiles and environment, including intra-vendor and inter-vendor
scenarios.
For inter-vendor scenarios, the X2AP Load Indication procedure including RNTP, IOI
and HII Information Elements are used in order to optimize the HetNet environment.
For intra-vendor scenarios, vendor-defined messages are defined in order to optimize
the small cell layer. The coordination amongst cells is performed via X2AP (although
the ICIC function is coordinated through the X2 interface, different algorithms may be
used by every vendor implementation).
Other mitigation techniques, like power control and frequency hopping on PUSCH are
also supported. Please see section on SON features for more information on
optimization against interference.
The following interference management features are supported by the Apex Lifestyle

• Frequency Selective Scheduling
• Dynamic Inter-Cell Interference Coordination in DL & UL
• Inter-vendor Dynamic Inter-Cell Interference Coordination in UL and DL via X2
interface
• Dynamic Downlink Power Allocation
• PDCCH power control
• Frequency hopping on PUSCH types 1 and 2
• Interference Shaping in DL & UL
