Data processing method and related device

A method, comprising:

• obtaining a 64-bit/66-bit code block stream;
• obtaining a first check field based on the 64-bit/66-bit code block stream, wherein the first check field is used to check the 64-bit/66-bit code block stream;
• mapping a following 64-bit/66-bit code block that follows the 64-bit/66-bit code block stream to a payload area of a data frame, wherein the first check field is carried in the following 64-bit/66-bit code block;
• and
• sending the data frame.

A device, comprising:

• at least one processor configured to:
• obtain a 64-bit/66-bit code block stream of a medium access control (MAC) frame;
• obtain a first check field based on the 64-bit/66-bit code block stream, wherein the first check field is used to check the 64-bit/66-bit code block stream;
• map a following 64-bit/66-bit code block that follows the 64-bit/66-bit code block stream to a payload area of a data frame, wherein the first check field is carried in the following 64-bit/66-bit code block;
• and
• a transceiver configured to send the data frame.

A computer storage medium storing instructions, and when the instructions are executed on a computer, the computer is enabled to:

• obtain a 64-bit/66-bit code block stream;
• obtain a first check field based on the 64-bit/66-bit code block stream, wherein the first check field is used to check the 64-bit/66-bit code block stream;
• map a following 64-bit/66-bit code block that follows the 64-bit/66-bit code block stream to a payload area of a data frame, wherein the first check field is carried in the following 64-bit/66-bit code block;
• and
• send the data frame.
