Hi,

HARQ, RACH is one of the important as well as complicated topics to masters, in this case UE will not ask for grant for sending HARQ, since HARQ is not a data, so UE cannot ask for grant. Here UE will wait for certain time, if there is no response from network it will consider it as NACK. it needs more thorough understanding from physical layer, but just to conclude, UE will not ask for grant.

Thanks
