RLM and beam failure detection based on a mix of different reference signals

A user equipment (UE), comprising:

• transceiver circuitry configured for receiving beam-formed downlink signals;
• and
• processing circuitry operatively associated with the transceiver circuitry and configured to:
• perform measurements based on a plurality of radio link management (RLM) measurement sources received in the beam-formed downlink signals, wherein the measurements indicate a quality of a given cell or beam, and wherein the plurality of RLM measurement sources comprises:
• one or more first reference signals (RSs) and one or more second RSs of a different type than the first one or more RSs;
• and
• for each of a plurality of evaluation periods and for each of the plurality of RLM measurement sources used to perform measurements, compare a measurement for the respective RLM measurement source with an out-of-sync threshold;
• trigger an out-of-sync event per evaluation period based on said comparing;
• and
• perform one or more RLM actions based on determined occurrences of out-of-sync events.
