Abstract

An embodiment of the present invention provides a code block segmentation method, a terminal, a base station, and a computer-readable storage medium. The method includes: the base station determines to use the maximum length of the first preset information bit for code block segmentation or uses the second preset information bit The maximum length is used for code block segmentation; if it is determined that the first preset information bit maximum length is used for code block segmentation, the base station divides the transport block into one or more segments with the first preset information bit maximum length as the upper limit. segment; if it is determined to use the second preset information bit maximum length for code block segmentation, the base station divides the transport block into one or more segments with the second preset information bit maximum length as the upper limit; wherein, the The maximum length of the first preset information bits is greater than the maximum length of the second preset information bits, so as to solve the problem of code block segmentation when there are two maximum information block lengths.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a code block segmentation method, a terminal, a base station and a computer-readable storage medium. Background technique [0002] 3GPP (3rd Generation Partnership Project, Third Generation Partnership Project) uses LDPC (Low Density Parity Check Code, Low Density Parity Check Code) for 5G (abbreviation of fifth generation mobile communication technology) NR (New Radio, new wireless ) application scenarios of Enhanced Mobile Broadband (eMBB, Enhanced Mobile Broadband). [0003] LDPC obtains a parity check matrix that supports a specific information length and code rate by using a lifting method on a base graph to perform encoding and decoding. Using a base graph designed for a larger message block length will lose the performance of the short message block LDPC, and will also reduce the latency (delay) of the short message block, which is not conducive to URLLC (u...
