Abstract
Aspects of the present disclosure provide adaptive radio link monitoring for machine type communication(s) (MTC), enhanced MTC (eMTC), and/or narrowband Internet-of-Things (NB-IoT). In one aspect, a method is provided which may be performed by a user equipment (UE). The method generally includes receiving a first configuration of parameters for receiving downlink control channel signaling, the first configuration of parameters associated with a first coverage level; measuring at least one parameter related to channel conditions; determining one or more dynamic radio link monitoring (RLM) threshold values for the at least one parameter based, at least in part, on the first configuration of parameters; and performing RLM functions based on the one or more dynamic RLM threshold values. The threshold may comprise early out thresholds that occur before out-of-sync (OOS) or in-sync thresholds. The thresholds may be determined using lookup tables.
