AI Technical Summary
Technical Problem
Existing technologies have insufficient decoding throughput in services such as extended reality, and cannot meet the high-performance requirements.
Method used
The long code block is divided into C short code blocks. Each short code block is independently encoded to generate a second parity bit set. During decoding, decoding is first performed based on the C second parity bit sets. If the decoding fails, the N first parity bit sets are used for decoding. This method reduces decoding complexity and improves throughput.
Benefits of technology
By reducing the complexity of decoding long code blocks, the throughput of channel coding and decoding is increased, thereby improving decoding efficiency.

Abstract
The invention relates to channel coding in the field of communications. In the existing channel coding technology, a coding end carries out channel coding on a CB, the CB is a long code block, the decoding complexity of the long code block is high, and the decoding efficiency is low. In the application, a coding end divides a CB into a plurality of short code blocks, each short code block is independently coded to generate a plurality of corresponding second check bit sets, and the plurality of short code blocks are coupled together based on N first check bit sets to form a first bit sequence. In the decoding process, each short code block can be decoded based on the plurality of second check bit sets, if the decoding is successful, a decoding result is output, and the first bit sequence is not decoded based on the N first check bit sets any more. Therefore, high-complexity long code block decoding is converted into low-complexity short code block decoding, and the decoding efficiency is improved, so that the decoding throughput is improved.
