1. A method for a wireless transmit/receive unit (WTRU) for performing configured grant (CG) uplink (UL) transmission, the method comprising:
receiving configuration information indicating a plurality of CG configurations for CG UL transmission;
transmitting a first CG UL transmission, which includes a plurality of code block groups (CBGs), via first CG UL transmission resources included in two or more sub-bands of a first set of available sub-bands based on: (1) a number of the CBGs for transmission, and (2) transmission parameters of a first CG configuration;
receiving CBG-based hybrid automatic repeat request acknowledgment (HARQ-ACK) feedback information associated with the CBGs;
determining second CG UL transmission resources that are entirely within the two or more sub-bands of the first set of available sub-bands based on: (1) the first CG UL transmission resources associated with the CBG-based HARQ-ACK feedback information, (2) a number of one or more of the CBGs for retransmission, and (3) transmission parameters of a second CG configuration; and
transmitting a second CG UL transmission, which includes the one or more of the CBGs for retransmission, via the second CG UL transmission resources.
