Abstract
In one aspect, a method in a wireless device for facilitating a transition of the wireless device between an active state and an inactive state or idle mode includes storing an identifier of an idle mode synchronization signal of a source node serving the wireless device responsive to entering an active state from an inactive state or idle mode, reentering the inactive state or idle mode and monitoring the idle mode synchronization signal of the source node while in the inactive state or idle mode.
