- There are four kinds of starting point selection positions and the input bit stream corresponding to the four positions is called 4 Redundancy Version (RV).
- RV Redundancy Version
- the output bit stream of four redundant versions is called a redundancy version. sequence.

- the user equipment receives the OFDM symbol transmitted by the base station in slot n.
- the user equipment performs FFT processing on the received OFDM symbol, converts the OFDM symbol into a modulation symbol, and searches for a modulation sent to the user equipment in the time-frequency resource block corresponding to the slot n according to the time-frequency resource location indicated by the base station.
- the symbol, the modulation symbol transmitted to the user equipment is referred to as a sequence of modulation symbols in this embodiment.
- the user equipment demodulates the modulation symbol sequence obtained after the FFT processing to obtain a scrambling sequence.
- the user equipment performs a modulo two-add operation on the scrambling sequence by using a preset scrambling code sequence to obtain a redundant version of the redundancy version.
- the user equipment performs de-synchronization matching on the redundancy version sequence obtained by S213 to obtain a channel coding sequence.

The same indicates that the check passes, and the user equipment sends an ACK to the base station on the time slot n+t1; if not, it indicates that the check fails, and the user equipment sends a NACK to the base station on the time slot n+t1. It should be noted that if the TB is segmented on the base station side, the user equipment needs to perform verification on each CB, and then perform verification on the entire TB. After two successful verifications, the verification is passed, otherwise the verification is not performed. by.
- the base station If the base station receives the ACK sent by the user equipment in the time slot n+t1, confirms that the transport block is successfully transmitted, and releases the HARQ process of the transport block; if the base station receives the NACK sent by the user in the time slot n+t1, it is confirmed that the transport block is not transmitted. Upon success, the base station retransmits another redundancy version to the user equipment at time slot n+t1+t2. Therefore, the method for retransmitting the data is that the base station needs to receive the NACK returned by the user equipment before performing retransmission. Generally, the time length of the eight time slots is required to be retransmitted. In addition, the base station needs to retransmit the entire transport block when receiving the NACK fed back by the user, and the amount of retransmitted data is large and occupies a large amount of transmission resources.
