Abstract

A controller arrangement comprising a transceiver capable of communication via a wireless communication network, a controller arranged to control a physical entity at which the controller arrangement is arranged, and an interface between the transceiver and the controller is disclosed. The transceiver is arranged to provide information via the interface about present or imminent interrupts in the communication via the wireless network. The controller is arranged to operate in at least a first state when the information indicates that no interrupts are present or imminent, wherein the first state includes closed loop control from a remote entity via the wireless communication network, and a second state when the information indicates that interrupts are present or imminent, wherein the second state includes autonomous control operations by the controller. A method and computer program are also disclosed.
