    Abstract: A user equipment may be configured to perform beam failure detection enhancement. In some aspects, the user equipment may receive a beam failure detection reference signal (BFD-RS) from a base station, detect an occurrence of an interference event based on a first measurement of the BFD-RS or a channel event based on a second measurement of the BFD-RS, and update count information based on a detection function and the occurrence. Further, the user equipment may determine that at least one of a first timer for interference events or a second timer for channel events is active, and determine whether to perform a beam failure recovery process based on comparing a total count of the count information to a predefined threshold value.

    Abstract: Methods, systems, and devices for wireless communications are described. Wireless communications systems may support beam measurements triggered by a wake-up signal (WUS) and that triggers an active duration of a receiving user equipment (UE). The WUS may trigger the receiving UE to perform a beam sweeping procedure during a beam measurement occasion that immediately preceding the active duration, or the UE may perform the beam sweeping procedure in the WUS resource itself. A UE may perform beam measurement procedures during active durations of a discontinuous reception (DRX) cycle, or outside of active durations of the DRX cycle. A receiving UE may be configured with a timing for performing a beam measurement procedure based on one or more offset values. The timing offset values may indicate a timing during active durations or prior to active durations.

    Abstract: Methods, systems, and devices for wireless communications are described to support inclusion of layer 1 (L1) or layer 2 (L2) cell mobility information within a layer 3 (L3) handover command. A base station may transmit, to the UE, signaling indicating for the UE to perform a measurement on a first set of cells. The UE may perform the measurement on the first set of cells and may transmit, to the base station, an indication associated with the measurement on the first set of cells. In response to the indication, the base station may transmit, to the UE, an L3 handover command, where the L3 handover command may include L1 or L2 cell mobility information, such as an indication of a second set of cells that the UE is to use for L1 or L2 cell mobility after completing the L3 handover command.
