Methods and apparatuses are provided for cell reselection at a mobile terminal. A first cell measurement is performed with respect to a serving cell and a first set of one or more cells included in a neighbor cell list. A second cell measurement is performed to detect a second set of one or more cells that are not included in the neighbor cell list, based on the first cell measurement. One or more candidate cells that satisfy cell reselection criteria are determined from among the first set of one or more cells and the second set of one or more cells. One of the one or more candidate cells is reselected.
