1. A method for wireless communication, comprising:
receiving, from a current cell, system information advertising, for at least one cell of one or more other cells, multiple multicast and/or broadcast service (MBS) identifiers of multiple MBSs provided by the at least one cell, an indication of a first frequency over which the at least one cell provides a first one of the multiple MBSs, and an indication of a second frequency over which the at least one cell provides a second one of the multiple MBSs;
detecting one or more cells, including at least a portion of the one or more other cells, for idle-mode cell reselection from a current cell;
evaluating at least the portion of the one or more other cells for idle-mode cell reselection including determining, based on the system information, a target cell of the one or more other cells that provides a UE interested MBS and a frequency over which the target cell provides the MBS; and
performing idle-mode cell reselection to the target cell including switching from a serving frequency to the frequency over which the target cell provides the MBS.
