A mobile terminal device may include a radio processing circuit and a baseband processing circuit adapted to interact with the radio processing circuit. The baseband processing circuit may be configured to identify one or more multicast control data notification messages available for reception during a first multicast control data window, determine whether any of the one or more multicast control data notification messages are not received during the first multicast control data window, and trigger receiving of multicast control data of a second multicast control data window when a predefined quantity of the one or more multicast control data notification messages are not received during the first multicast control data window.
