Cell selection and reselection for closed subscriber group cells
Abstract
Apparatuses and methods are provided for performing cell reselection. A method includes camping on a non-closed subscriber group (CSG) cell that is selected using frequency priorities; scanning other frequencies for non-CSG cells and CSG cells; detecting a CSG cell being a highest ranked cell on a frequency different than a frequency of the non-CSG cell that the WTRU is camped on; and selecting the detected CSG cell, being on a whitelist, and disregarding the frequency priorities in cell selection.
