Abstract (en)

[origin: WO2020041205A1] An apparatus of a next generation NodeB (gNB) comprises one or more baseband processors transmit one or more reference signals to a user equipment (UE) to perform radio link monitoring (RLM), beam failure detection (BFD), candidate beam detection for beam failure recovery (BFR), and beam reporting. The one or more reference signals are to be transmitted to the UE at different power levels during different time intervals. The apparatus can include a memory to store the one or more reference signals.
