Abstract

A method for a UE performing a Hybrid Automatic Repeat Request (HARQ) process for a deprioritized uplink (UL) grant is disclosed. The method comprises receiving, 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 a 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 retransmission on a third UL resource, the retransmission corresponding to the second UL transmission scheduled by the deprioritized UL grant and flushing a HARQ buffer of a HARQ process for the second UL transmission in response to receiving the third UL grant.
