Methods and apparatus are described herein for improved efficiency of a wireless transmit/receive unit (WTRU) transmitting transport blocks (TBs). A WTRU may receive configuration information including uplink resources associated with one or more repetition bundles and a target number of retransmissions for a transport block (TB) associated with at least one hybrid automatic repeat request (HARQ) process. Then, the WTRU may transmit a first TB using a first uplink resource in a first repetition bundle based on the configuration information. Further, the WTRU may increment a retransmission counter. On a condition that the retransmission counter is less than the target number of retransmissions, the WTRU may determine a second uplink resource. Further, the WTRU may retransmit the first TB in the determined second uplink resource. Also, the WTRU may further increment the retransmission counter. Moreover, the first, second and third uplink resources may be physical uplink shared channel (PUSCH) resources.
