Hybrid automatic repeat request (hybrid ARQ or HARQ) is a combination of high-rate forward error correction (FEC) and automatic repeat request (ARQ) error-control. In standard ARQ, redundant bits are added to data to be transmitted using an error-detecting (ED) code such as a cyclic redundancy check (CRC). Receivers detecting a corrupted message will request a new message from the sender. In Hybrid ARQ, the original data is encoded with an FEC code, and the parity bits are eith… WebIn the reactive scheme, when the UE has finalized its initial uplink data transmissions, its signal is processed at the BS, which will then transmit a HARQ feedback (ACK/NACK). The UE re-transmits the same payload upon reception of a NACK.
