Abstract: Outage detection and recovery in heterogeneous networks may benefit from sub-cell level, multi-layer degradation detection, diagnosis, and recovery. For example, cell outage detection and cell outage compensation may benefit from appropriate use of sub-cell level and multi-layer diagnosis and recovery techniques applied to degradation and outage scenarios.
