Abstract: Certain aspects relate to methods and apparatus for avoiding and/or escaping cell range expansion (CRE) in a heterogeneous network (HetNet). A user equipment (UE) may detect the occurrence of one or more conditions while the UE is in a region of cell range expansion (CRE) in which the UE may be handed over from a first cell of a first power class type to a second cell of a second power class type, the second power class type being lower than the first power class type. The UE may take action to stop being served by the second cell or avoid being handed over to the second cell in response to the detection.
