However, the major drawback of the so-called reactive HARQ, which is one of the fundamental mechanisms of Long Term Evolution (LTE) and 5G, is an introduced latency due to the HARQ Round Trip Time (RTT). It has to be noted that the reactive Incremental Redundancy (IR) HARQ approaches the ergodic channel capacity of Rayleigh block
WebDec 16, 2024 · HARQ retransmissions at MAC react faster to channel conditions and improve performance for delay-sensitive applications. Applications requiring 100Mbps may need highly reliable connections to avoid triggering TCP congestion-avoidance mechanism.

WebHowever, HARQ, also known as reactive HARQ, increases the end-to-end latency because a feedback from the receiver is required at each retransmission round. This drawback is compensated by proactive HARQ that continuously transmits further retransmissions until an ACKnowledgment (ACK) is received [3], [4].
