Abstract: This disclosure relates to radio link monitoring techniques. According to some embodiments, a wireless device may establish a radio link with a cellular base station according to a radio access technology. The base station may provide reference signals, control signals, and data signals to the wireless device via the radio link. The wireless device may perform radio link monitoring of the radio link using characteristics of decoding performance for one or more of the control signals and the data signals. Performing radio link monitoring of the radio link may include determining whether the radio link is in-sync or out-of-sync and determining whether radio link failure has occurred.
