1. A user equipment (UE), comprising:
a transceiver configured to operate in a wireless network; and
a processor coupled to the transceiver, configured to:
receive a semi-persistent scheduling (SPS) Physical Downlink Shared Channel (PDSCH) transmission or a Physical Downlink Control Channel (PDCCH) transmission corresponding to an SPS PDSCH release;
generate a first Hybrid Automatic Repeat Request (HARQ)-ACK information bit corresponding to reception of the SPS PDSCH transmission or the PDCCH transmission, wherein a valid Uplink (UL) transmission slot corresponding to the reception is not available;
determine a length, l, of a first HARQ-ACK window associated with a UL transmission slot n, wherein the reception of the SPS PDSCH transmission or the PDCCH transmission corresponding to the SPS PDSCH release occurs during the first HARQ-ACK window, wherein the length, l, is based on an ending symbol, L, of the first HARQ-ACK window, where L is a last DL symbol that is earlier than symbol i-Δ, where i is a first symbol of a Physical Uplink Control Channel (PUCCH) transmission of the UL transmission slot n, where Δ is a UL transmission preparation time of the UE;
determine a starting slot of a second HARQ-ACK window as n-k, wherein k is an offset value configured for the UE; and
transmit, using the transceiver, the first HARQ-ACK information bit in the PUCCH transmission of the UL transmission slot n, wherein n is an integer.
