Title: Idle mode cell reacquisition and reselection

Abstract: Techniques for cell reacquisition and reselection that increases time spent in low-power mode while effectively monitoring neighbor cells are disclosed. In one aspect, one or more windows around the expected location of the serving cell are searched in the period of time prior to the page indicator. In another aspect, intra-frequency neighbor cells are searched first to determine reselection candidates. Various other aspects are also presented. These aspects have the benefit of increasing time spent in low-power mode, thereby reducing power consumption and increasing standby time.
