Method for implementing data mapping and transmission and related product

A method for implementing data mapping and transmission, comprising:

• receiving M code block groups (CBGs) mapped to at least one transmission unit, wherein the M CBGs are obtained by dividing N code blocks, the N code blocks are obtained by segmenting data to be transmitted, a difference between numbers of code blocks in any two CBGs is less than or equal to 1, the M CBGs comprise a first CBG and at least two second CBGs, and a number of code blocks in the first CBG is greater than a number of code blocks in each of the at least two second CBGs;
• the at least one transmission unit comprises a first physical resource corresponding to the first CBG and a second physical resource corresponding to the at least two second CBGs, and the first physical resource is ahead of the second physical resource in time domain, N and M are positive integers, N is greater than or equal to M, and M is greater than or equal to 3;
• and
• decoding each of the M CBGs after the respective CBG is received.

A sender, comprising a processor, a memory, a radio frequency chip and a program, wherein

• the memory is configured to store the program;
• the processor is configured to execute the program to:
• segment data to be transmitted into N code blocks, and divide the N code blocks into M code block groups (CBGs), wherein a difference between numbers of code blocks in any two CBGs is less than or equal to 1, N and M are positive integers, N is greater than or equal to M, and M is greater than or equal to 3;
• and
• the radio frequency chip is configured to:
• map the M CBGs to at least one transmission unit;
• and
• transmit the M CBGs on the at least one transmission unit;
• wherein the M CBGs comprise a first CBG and at least two second CBG, and a number of code blocks in the first CBG is greater than a number of code blocks in each of the at least two second CBGs;
• and
• wherein the at least one transmission unit comprises a first physical resource corresponding to the first CBG and a second physical resource corresponding to the at least two second CBGs, and the first physical resource is ahead of the second physical resource in time domain.
