Abstract

See full text

A wireless transmit/receive unit (WTRU) may receive one or more physical downlink shared channel (PDSCH) transmissions and each PDSCH transmission may be associated with downlink control information (DCI) and a group of PDSCH transmissions. Further, the WTRU may determine a first group or a second group based on an indication received in DCI associated with at least one of the PDSCH transmissions. Then, the WTRU may generate hybrid automatic repeat request (HARQ)-acknowledgment (ACK) feedback for data received in one or more PDSCH transmissions associated with the determined group. Moreover, the WTRU may transmit the HARQ-ACK feedback. In an example, the DCI which includes the indication may schedule a plurality of PDSCH transmissions included in the determined group. In another example, the DCI which includes the indication may further include a first codepoint mapped to the first group or a second codepoint mapped to the second group.
