Abstract: The present disclosure presents a method and apparatus for regaining service at a user equipment. For example, the disclosure presents a method for receiving a neighbor cell list from a serving cell, and scanning to identify target cells by the user equipment, wherein the target cells include neighbor cells included in the neighbor cell list and detected cells not included in the neighbor cell list. In addition, such an example method may include determining that the user equipment cannot successfully camp on any one of the neighbor cells, and attempting to camp on one of the detected cells. As such, an improved method and apparatus for regaining service at a user equipment may be achieved.

Abstract: Methods and apparatus are described for cell reselection when camping on a small cell. The methods and apparatus include determining, by a user equipment (UE), whether to perform a cell reselection evaluation after camping on a small cell communicating with the UE; performing a measurement of a signal transmitted by the small cell in response to determining whether to perform the cell reselection evaluation; determining that a signal characteristic based on the measurement of the signal of the small cell falls below a cell reselection measurement triggering threshold; performing a measurement of a respective signal transmitted by one or more other cells in only a serving frequency; ranking the small cell relative to the one or more other cells; and remaining camped on the small cell when the small cell is ranked higher than the one or more other cells.

Abstract: Apparatus and methods of maintaining a cell database for wireless communications include discovering a second cell to which a user equipment may reselect. In an aspect, the user equipment may be currently served by a first cell and the second cell is a closed subscriber group cell. Further, aspects include querying a fingerprinting database to determine whether the second cell was previously recorded in the fingerprinting database. Upon determining that the second cell was not previously recorded, further aspects include adding the second cell to the fingerprinting database. Adding the second cell may comprise indicating an association between the first cell and the second cell in the fingerprinting database.

Abstract: The present disclosure presents a method and apparatus for determining reselection parameters for detected cells. For example, the method may include receiving system information block (SIB) data associated with one or more cells in a neighbor cell list (NCL). In such example, the SIB data may include a ranking offset parameter associated with each of the NCL cells. Furthermore, such an example method may include detecting a cell that is not in the NCL, determining a reselection ranking value associated with each of the NCL cells, the detected cell and the serving cell. In addition, in some examples, such method may include ranking the one or more NCL cells, the detected cell and the serving cell in a ranking list based on the reselection ranking values. As such, reselection parameters for detected cells may be determined.
