Abstract
A user equipment (UE) device is disclosed. The UE device comprises a processor configured to perform operations comprising receiving a downlink control information (DCI) from a base station. In some embodiments, the DCI comprises an indication to trigger a Type-3 hybrid automatic repeat request (HARQ) acknowledgement (ACK) feedback signal. The operations further comprise generating the Type-3 HARQ ACK feedback signal, based on processing the DCI. In some embodiments, the Type-3 HARQ ACK feedback signal comprises one or more HARQ-ACK bits for semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH) release(s). In some embodiments, each of the one or more HARQ-ACK bits for SPS PDSCH release(s) is adapted to include HARQ-ACK information for an SPS PDSCH release associated with the UE. Further, the operations comprise sending the Type-3 HARQ-ACK feedback signal to the base station.
