WebDec 18, 2024 · Adaptive Cross-Packet HARQ ( XP -HARQ) is a technique that varies the number of bits with each retransmission. A retransmission can contain bits from two packets and joint decoding happens at the receiver. Sender selects codebooks based on current channel conditions. WebHowever, HARQ, also known as reactive HARQ, increases the end-to-end latency because the transmitter requires feedback from the receiver after each transmission round in form of an ACKnowledgment (ACK) or Non-ACKnowledgment (NACK).
