Methods, apparatus and systems for enhanced uplink data transmission on configured grants

A wireless transmit and receive unit (WTRU), the WTRU, comprising:

• a processor;
• a transceiver unit;
• and
• a storage unit,
• the processor operating with the transceiver unit and the storage unit configured to:
• transmit a first Transport Block (TB) associated with a Hybrid Automatic Repeat Request (HARQ) process using a first configured grant (CG) resource of at least on CG, wherein the first CG resource being associated with the HARQ process;
• and
• start a first CG timer associated with the HARQ process and a first CG retransmission timer associated with the HARQ process;
• receive HARQ feedback information associated with the HARQ process, wherein the received HARQ feedback information is associated with the first transport block;
• stop the first CG retransmission timer associated with the HARQ process, based on receiving HARQ feedback information;
• stop the first CG timer associated with the HARQ process, based on receiving HARQ feedback information indicating acknowledgment;
• and
• on condition that the first CG timer associated with the HARQ process is stopped and on condition that the first CG retransmission timer associated with the HARQ process is stopped, transmit a second TB associated with a new data transmission using a second CG resource of the at least one CG, wherein the second CG resource is associated with the HARQ process.
