Abstract: Devices, methods and non-transitory computer-readable medium for adaptively selective retransmissions in wireless communications are disclosed. The present application allows enhancing short packet data retransmission performance under short delay constraints. Using a retransmission indication for at least one segment of consecutive forward error correction (FEC) encoded bits reduces feedback signaling overhead compared to signaling retransmission requests individually for each of the coded bits. Accordingly, active hybrid automatic repeat request (HARQ) transmissions with low amounts of feedback information are enabled.
