description Some embodiments relate to a user equipment (UE) configured to modify at least one signal strength threshold value to provide improved operation for link budget limited devices when performing cell selection or reselection. In some embodiments, the UE may receive a threshold value indicating a minimum received signal strength for camping on a cell. The UE may determine an offset value based on operating parameters of the UE, and may determine a modified threshold value by applying the offset value to the received threshold value. The UE may then compare the modified threshold value to a signal strength measurement of a signal received from a base station associated with the cell. The UE may camp on the cell if the modified threshold value is less than the signal strength measurement, and not camp on the cell if the modified threshold value is greater than the signal strength measurement.
