    receive a beam-specific current DCI at the UE on at least one of the transmit beams, said received current DCI including information about beam-specific previous DCIs transmitted to the UE on any of the multiple transmit beams within a predefined time window preceding a time unit in which the current DCI was received;

    use the information about the beam-specific previous DCIs to determine that at least one of the multiple transmit beams has been blocked; and
