Radio resource control (RRC) configuration

Embodiments relate to a device configured to implement a Radio Resource Control RRC configuration to support radio communication between the device and another device in a wireless communication network. The device comprises a Radio Resource Control kernel 100 configured to implement: a radio processing unit 200, the radio processing unit being associated with a RRC configuration which enables radio communication between the device and the another device; and a further radio processing unit 300, the further radio processing unit being associated with a further RRC configuration which supports radio communication between the device and the another device. The radio processing unit and further radio processing unit are concurrently implementable by the Radio Resource Control kernel and the RRC configuration associated with each of the radio processing unit and further radio processing unit is retained by the Radio Resource Control kernel upon detection of one or more radio configuration event.
