5G NR Hybrid ARQ - Devopedia
WEBDec 16, 2021 · Synchronous HARQ is not suitable in 5G NR due to dynamic TDD and operation in unlicensed spectra. In LTE synchronous UL HARQ, the same process ID is used every eighth subframe. An LTE UE responds with HARQ ACK 3ms after receiving the downlink data. 5G NR has more flexibility to respond faster for URLLC use cases.

Hybrid automatic repeat request - Wikipedia
WEBHybrid 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).

WEBDetermining the number of bits for HARQ ACK/NACK. In LTE, the number of HARQ bits is determined by relatively simple factors like the number of transport block (number of Codeword) and number of carriers. In general, UE assigns 1 bits per one transport block. For example, for 4x4 MIMO or higher, a cell use two transport blocks (two code words).

Subcode-Based Early HARQ for 5G - IEEE Xplore
WEBHybrid Automatic Repeat Request (HARQ) is used in LTE to achieve high robustness in an efficient way with the cost of introducing additional latency. In this paper, we propose a new early HARQ scheme based on LDPC subcodes (SC E- HARQ), which enables to provide faster feedback and thus an earlier retransmission.
