Abstract
Apparatuses, systems, and methods for user equipment (UE) devices to more efficiently scan frequency bands for potential base stations may include a UE configured maintain a first list of cells for which a cellular scan has been successful and a second list of cells for which a cellular scan has not been successful. The UE may be configured perform a first cellular while camped on a first cell at an expiration of a scan timer and, if the cellular scan is not successful, the increment a first failure count variable associated with the first cell and add the first cell to the second list if the first cell is not present on the first or second list. Additionally, if the first cellular scan is successful, the UE may be configured to add the first cell to the first list if the first cell is not present on the first list.
