1. A user equipment (“UE”) for wireless communication, comprising:
at least one memory; and
at least one processor coupled with the at least one memory and configured to cause the UE to:
receive a downlink control information (“DCI”) comprising a grant for multiple transmission occasions associated with different hybrid automatic repeat request (“HARQ”) processes, wherein the DCI identifies a first HARQ process associated with a first transmission occasion of the multiple transmission occasions;
generate a first transport block (“TB”) for the first HARQ process;
perform a first listen-before-talk (“LBT”) procedure for transmission of the first TB associated with the first transmission occasion, wherein the first LBT procedure results in LBT failure;
transmit the first TB during a second transmission occasion associated with a second HARQ process in response to the first LBT procedure resulting in LBT failure; and
map the first TB to the second HARQ process in response to the first LBT procedure resulting in LBT failure.
