Abstract: The disclosure provides methods and apparatus to improve public land mobile network search time. A user equipment (UE) may determine a subset of channels within a frequency band based on a stored identifier of a channel used by a previously acquired cell, each channel in the subset being spaced from the channel used by the previously acquired cell by a different multiple of a set spacing, the set spacing being greater than a spacing between adjacent channels. The subset of channels may be scanned to determine a signal strength of each channel in the subset. The UE may rank each channel in the subset according to the determined signal strength of the channel and attempt to acquire a cell using a channel in the subset based on the ranking.
