1. A method of operating a receiving radio node in a wireless communication network, the receiving radio node configured to transmit a D quantity of bits representing feedback signaling, D being an integer, the method comprising:
receiving a downlink control information (DCI) message that schedules M physical down link shared channel (PDSCH) transmissions, M being an integer greater than D;
transmitting the feedback signaling for reception of the M PDSCH transmissions, the feedback signaling being based at least in part on a logical AND operation performed on a number of bits,
the number of bits being logically ANDed is a subset of M bits representing feedback for the M PDSCH transmissions, and
the number of bits being logically ANDed is equal to M−D+1 up to D−1 bits, and a number of the logically ANDed bits is less than the D quantity of bits representing feedback signaling.
