The embodiments herein relate to a method performed by UE, a UE, a network node or gNB and a method performed by the gNB for handling retransmissions in a wireless telecommunications system and resolving misalignment between the UE and the gNB. According to exemplary embodiments, there is provided a retransmission counter placed or implemented at the UE and/or the gNB which is configured to count every failing data packet (i.e., the receiver(s)/transmitters is/are informed via the NACK messages or the NACK timers). There is also provided a retransmission assignment indicator message configured to include, fully or partially: the content of said counter and the content or the structure of the CGB (Code Block Group), e.g., either all CBGs are retransmission versions or part of the CGBs are retransmission versions.
