1. A baseband (BB) processor of a user equipment (UE), the BB processor configured to perform operations comprising:
receiving a downlink control information (DCI) from a base station associated therewith, wherein the DCI comprises an indication to trigger a Type-3 hybrid automatic repeat request (HARQ) acknowledgement (ACK) feedback signal, and wherein the DCI further comprises information of a number of reserved bits including one or more reserved bits that are reserved to include HARQ-ACK information for one or more semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH) release(s) that are to be included in the Type-3 HARQ ACK feedback signal; and
generating the Type-3 HARQ ACK feedback signal for transmission to the base station, based on processing the DCI, wherein the Type-3 HARQ ACK feedback signal comprises the one or more reserved bits, wherein each of the one or more reserved bits is adapted to include HARQ-ACK information for an SPS PDSCH release associated with the UE.
