1. A baseband processor for a user equipment (UE), configured to:
receive, from a base station, configuration of a plurality of hybrid automatic repeat request (HARQ) process groups (HPGs), each HPG of the plurality of HPGs comprising one or more HARQ processes for physical downlink shared channel (PDSCH);
receive, from the base station, a downlink control information (DCI), wherein the DCI indicates one or more HPGs of the plurality of HPGs; and
triggered by the DCI and based on the one or more HPGs, generate a HARQ-ACK feedback signal for transmission to the base station.
