    摘要: Methods, systems and apparatus are provided for hybrid automatic repeat request (HARQ) processes for different transmission time interval (TTI) lengths. A wireless transmit/receive unit (WTRU) may link a first HARQ process and a second HARQ process. The WTRU may transmit a first transport block (TB) using the linked first HARQ process and a first HARQ buffer. The WTRU may receive a uplink (UL) grant and determine that the received UL grant is for a new transmission for the linked second HARQ process. The WTRU may release the first HARQ buffer based on a determination that the received UL grant is for the new transmission for the linked second HARQ process. Also, the WTRU may generate a second TB for the new transmission and store the new TB in the first HARQ buffer. The WTRU may transmit the second TB using the linked second HARQ process and the first HARQ buffer.
