WebThe purpose of LTE is to bring high data rates and embrace quick data transfer and reliable communication. To achieve reliable communication, LTE has two mechanisms to detect a nd correct the errors, which are ARQ and HARQ. This thesis describes different types of ARQ and HARQ, as well it was described why it is better to choose particular type of … WebJan 1, 2013 · In current LTE systems, Hybrid-ARQ (HARQ) using CC (Chase-Combine) or IR (Incremental Redundancy) is performed to increase efficiency and reliability. But when the signal-to-noise ratio (SNR) is high, HARQ will do little to help. People always consider HARQ an affiliated scheme in communication systems for its sensitivity in SNR.

WebThis work investigates HARQ buffer management by leveraging information-theoretic achievability arguments based on random coding. Speciﬁcal ly, standard HARQ schemes, namely Type-I, Chase Combining and Incremental Redundancy, are ﬁrst studied under the assumpt ion of a ﬁnite-capacity HARQ buffer by considering both coded

Webuse soft combining technique rather than using log-likelihood ratios (LLRs) as the a priori information. Chase combining (CC) and incremental redundancy (IR) are two main soft combining techniques in HARQ schemes. For chase combining, the same coded bits are retransmitted and combined with previous received transmissions using diversity … Webwith HARQ, the acknowledgment (ACK) signal is fed back to the transmitter, which sends a new packet; otherwise, it repeats the old packet when a negative ACK (NACK) is received. HARQ has two common types, CC-HARQ and IR-HARQ known as chase combining and incremental redun-dancy HARQ, respectively. In CC-HARQ, the whole packet

Webare widely considered in practical systems. One is Chase combining (HARQ-CC), where each retransmission block is identical to the original code block; and the other is incre-mental redundancy (HARQ-IR), where each retransmission consists of new redundancy bits from the channel encoder.
