Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The UE may receive radio resource control (RRC) signaling that configures reception of a plurality of physical downlink shared channels (PDSCHs) in a frame. The frame may comprise multiple slots, including one or more downlink slots and one or more uplink slots. The UE may determine a subset of the PDSCHs, such that for each of the PDSCHs of the subset, corresponding consecutive slots do not overlap the uplink slots. The UE may set a number of bits of a hybrid automatic repeat request acknowledgement (HARQ-ACK) codebook equal to a number of PDSCHs in the determined subset.
