 of neighbor cells to be able to manage handovers to these neighbors. Ideally, this database is continuously updated SO to be able to detect neighbors being switched off and on. Neighbors can operate either in-band (i.e., in the same band as the SON cell) or out-of-band (i.e., in a different band as the SON cell). Inter Cell Interference Coordination (ICIC)-targets to coordinate transmissions between cells in such a way that interference is mitigated as much as possible. For example by allocating time, frequency and power resources orthogonally between cells for UEs that are subject to this interference. Advanced ICIC schemes evolve to a SFN where frequency planning is not preconfigured but implemented dynamically on a slot-by-slot (in 5G: on a submillisecond) basis. Mobility Robustness Optimization-involves automated optimization of handover related parameters, to remove negative impact on user experience, for example, from handover ping-pong. Cell outage detection and self-healing networks-the capability to detect that cells are not functioning properly and to mitigate these effects by steering user traffic and coordinating cell repair (even if this is as simple as triggering a device reset procedure). For SON to work, it relies on Communication between cells-typically over a wireline (backhaul) connection that allows them to coordinate. Sensing capabilities to detect other transmitting cells, both in-band (obvious in the ICIC example) and out-of-band (obvious in the ANR example). This sensing is typically referred to as Network Listening Mode or Network Monitoring Mode (NMM). NMM has been standardized by the Small Cell Forum in the "LTE Network Monitor Mode Specification" document. For the LTE standard, the scope is defined as: to allow a femto cell to support cell RF self-configuration and interference management, which amongst others include (1) carrier and cell id selection, (2) DL TX power setting, (3) UE TX power setting, and (4) frequency reference. This is a relatively simple set of targets but defines
