Abstract: Methods and apparatus of monitoring cells in a wireless communication system may include determining existence of a condition for performing a cell search on a frequency. In addition, the methods and apparatus may include calculating an undetected energy-related value for a hypothetical undetected cell based on a measured energy-related value of each detected cell on the frequency in response to determining the condition for performing the cell search. The methods and apparatus may further include determining whether to perform the cell search based on the undetected energy-related value and a reselection criteria.

Abstract: The present disclosure presents example methods and apparatuses for improved cell searching in a wireless communications environment. For example, the disclosure presents example methods that can include computing a predicted serving signal strength associated with a serving cell where a mobility state of a user equipment is one of a stationary state or a low mobility state. Furthermore, in an aspect, the example method can include ascertaining a search threshold based at least on the predicted serving signal strength and generating a search integration length based on at least the search threshold. In addition, some example methods may include scanning for one or more reselection candidate cells based on at least the search integration length, wherein each of the one or more reselection candidate cells has a cell signal strength greater than the search threshold.
