Claim 0:
1. A method implemented by a wireless transmit/receive unit (WTRU) for wireless communications, the method comprising:
determining, for each of a plurality of downlink (DL) transmissions, a respective codebook process from a set of codebook processes based on a first indication associated with a respective codebook process index, wherein each of the plurality of DL transmissions is associated with one or more hybrid automatic repeat request (HARQ) feedback bits;
receiving, in downlink control information (DCI), a second indication to transmit a set of HARQ feedback bits using one or more uplink (UL) control resources, wherein the second indication comprises at least a codebook process index and a HARQ retransmission indicator;
determining one or more DL transmissions from the plurality of DL transmissions based on: 1) the respective codebook process determined for each respective DL transmission, 2) the received codebook process index, and 3) the received HARQ retransmission indicator; and
transmitting the set of HARQ feedback bits associated with the determined one or more DL transmissions using the one or more UL control resources.
