A.Error correction coding technology is to perform error correction and correction after the entire data packet is transmitted.

B.If the error correction scenario exceeds the FEC error correction range, ARQ and HARQ mechanisms will be used for retransmission.

C.The role of HARQ is to achieve a balance between time delay and packet loss rate, and this work cannot be completed by error correction coding.

D.Error correction coding is FEC forward error correction coding.
