Abstract
Systems and methods are disclosed for adjusting Radio Link Monitoring (RLM), Radio Link Failure (RLF) detection, RLF recovery, and/or connection establishment failure detection for wireless devices () in a cellular communications network () depending on mode of operation. In one embodiment, a node () in the cellular communications network () determines whether a wireless device () (e.g., a Machine Type Communication (MTC) device) is to operate in a long range extension mode of operation or a normal mode of operation. The node () then applies different values for at least one parameter depending on whether the wireless device () is to operate in the long range extension mode or the normal mode. The at least one parameter includes one or more RLM parameters, one or more RLF detection parameters, and/or one or more RLF recovery parameters. In doing so, signaling overhead and energy consumption within the wireless device () when operating in the long range extension mode is substantially reduced.
