1. A method comprising:
changing a configured grant retransmission counter when a transmission of a first packet occurs, wherein the first packet comprises at least one transport blocks;
maintaining the configured grant retransmission counter if a retransmission or an incremental redundancy transmission of the first packet occurs, wherein the retransmission is due to channel failure, decoding failure, or Listen Before Talk failure;
changing the configured grant retransmission counter when a second packet is transmitted, wherein the second packet is different from the first packet;
changing the configured grant retransmission counter by at least one if a counting criteria is performed on a transport block level or based on a number of erroneous code block group (s); and
generating a retransmission assignment indicator signal, wherein the retransmission assignment indicator signal conveys the value of the configured grant retransmission counter or derives the criteria of which code block groups are erroneous or conveys which transport block are erroneous.
