Systems and methods for early termination of feedback in respect of sidelink transmissions are provided. A first UE transmits at least one sidelink (SL) transmission of a first set of SL transmissions to a second UE, the first set of SL transmissions comprising an initial SL transmission and a set number of SL retransmissions. If no ACK is received, then the first UE transmits the set number of retransmissions. On the other hand, if an ACK is received, then the first UE transmits fewer than the set number of SL retransmissions when an ACK is received from the second UE before the set number of SL retransmissions has been completed. By transmitting fewer than all of the set number of SL retransmissions, resources can be freed up for other purposes. The approach may be used for SL configured grant transmission.
