1. A network node configured to:
configure each wireless device in a first group of wireless devices, including at least one wireless device, with a first radio network temporary identifier, RNTI, defined to address a group of wireless devices for physical downlink control channel, PDCCH, based wake-up signal, WUS, operation; and
cause transmission of signaling including a wake-up signal, WUS, for a first WUS monitoring occasion associated with the first group of wireless devices and use the first RNTI to scramble a Cyclic Redundancy Check, CRC, in the signaling, the WUS being based on a downlink control information, DCI, format that includes a bitmap, a bit in the bitmap being used for indicating whether or not a corresponding subgroup of the first group of wireless devices is targeted with the WUS, the WUS being configured to cause each wireless device in those subgroups of the first group of wireless devices that are targeted by the WUS to perform at least one action.
