Abstract: Systems, methods, apparatuses, and computer program products for beam failure detection and/or beam failure recovery procedures, for instance, for multi-panel user equipment (UEs) are provided. One method may include transmitting, by a UE, a beam report to a network to indicate an association between at least two downlink reference signals and at least two antenna panels at the user equipment or to indicate a selection of at least two downlink reference signals that will be used for downlink reception at the user equipment simultaneously. The method may also include activating the antenna panels corresponding to one or more of the at least two downlink reference signals, based on transmission configuration indicator (TCI) states updated by the network or based on the selection of the at least two downlink reference signals, and detecting beam failure based on at least two sets of beam failure detection resources for the active antenna panels.
