Abstract A wireless transmit/receive unit (WTRU) may receive downlink control information (DCI) including a downlink grant. Further, the WTRU may receive a downlink transmission scheduled by the downlink grant. Also, the WTRU may determine a start time for an uplink transmission, wherein the uplink transmission includes hybrid automatic repeat request (HARQ)-acknowledgment (ACK) information, wherein the HARQ-ACK information is based on the downlink transmission. In addition, the WTRU may determine an available processing time associated with the HARQ-ACK information. On a condition that the determined start time for the uplink transmission is later than an uplink symbol time that is at least the determined available processing time after the end of a time unit at the end of the downlink transmission, the WTRU may transmit the uplink transmission including the HARQ-ACK information.
