Embodiments of the invention provide methods, devices and computer programs arranged to control access to a Secondary Cell Carrier (SCC) by a user terminal. The user terminal having a first functional state in which the user terminal is arranged to monitor for a broadcast channel associated with the SCC, and a second functional state, different to said first functional state. One embodiment comprises an apparatus comprising a processing system arranged to cause the apparatus to: receive data indicative of a plurality of operational modes assigned to the SCC; and transmit a signalling message comprising data indicative of said plurality of operational modes for receipt by the user terminal, whereby to configure the user terminal into the first functional state, wherein the user terminal is arranged to selectively request access to resources of the SCC on the basis of a comparison between data contained in said signalling message and data contained in a transmission received on the broadcast channel.
