Claim 0:
1. A method for a user equipment (UE) performing a Hybrid Automatic Repeat Request (HARQ) process of an uplink (UL) grant for scheduling a retransmission, the method comprising:
receiving, from a base station (BS), a first UL grant scheduling a first UL transmission on a first UL resource and a second UL grant scheduling a second UL transmission on a second UL resource, the second UL resource at least partially overlapping the first UL resource in time domain;
determining the first UL grant as a prioritized UL grant;
determining the second UL grant as a deprioritized UL grant;
performing the first UL transmission scheduled by the prioritized UL grant;
receiving a third UL grant scheduling a third UL transmission on a third UL resource; and
before generating a first transport block for the third UL transmission in response to determining that the third UL grant is for indicating a retransmission of a second transport block stored in a HARQ buffer of the HARQ process:
determining whether a size of the third UL resource is different from a size of the second transport block corresponding to the second UL transmission, and
flushing the HARQ buffer and determining that a new data indicator (NDI) for the third UL transmission is toggled if the size of the third UL resource is different from the size of the second transport block, wherein:
the third UL resource is not overlapping the first UL resource in the time domain and is not overlapping the second UL resource in the time domain, and
the second UL grant is a configured grant (CG) and the third UL grant is a dynamic grant (DG).
