• cause transmission of the first acknowledgement feedback pertaining to the control information, the first acknowledgement feedback being transmitted in a physical layer channel;
• receive, from the transmitting radio node, the data signaling scheduled according to the scheduling type control information;
• and
• in response to receiving the data signaling, cause transmission, in a second control channel, of the second acknowledgement feedback pertaining to the data signaling based at least in part on the feedback codebook, the second control channel being a shared channel.
