Abstract: Techniques for performing cell reselection to obtain good performance are disclosed. In an aspect of the present disclosure, a user equipment (UE) performs cell reselection to a cell by applying one or more performance-based suitability criteria defined to provide good performance. In one design, the UE obtains a measured value for a cell (e.g., a femto cell) and also determines a threshold value for the cell. The threshold value is not broadcast by a wireless system. The UE determines the threshold value based on a target performance for a physical channel (e.g., a page indicator channel) from the cell. The UE determines a suitability criterion for the cell based on the measured value and the threshold value for the cell. The UE determines whether the cell is a suitable cell and also determines whether to perform cell reselection to the cell based at least on the suitability criterion.

Abstract: Methods and apparatus for communication comprise aspects that include performing a power management procedure for configuring a subset of network entities to receive one or more of downlink signal measurements and/or one or more uplink signal measurements. The methods and apparatus further comprise aspects that include storing the one or more one or more of downlink signal measurements and/or one or more uplink signal measurements associated with the subset of network entities at a database for managing transmit power at the subset of network entities.

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.
