Data processing method and device

An apparatus for wireless communication, comprising:

• a processor and memory containing executable instructions that when executed perform at least:
• determining a polar code encoding method according to the data characteristic of an information bit sequence, the data characteristic of the information bit sequence comprising a bit length value of the information bit sequence and a link direction of the information bit sequence, wherein the polar code encoding method comprises a parity-check polar code encoding or a cyclic redundancy check-aided polar code encoding, wherein in a first case that the bit length value satisfies a first condition, the parity-check polar code encoding is selected, and wherein the bit length value satisfies the first condition when the bit length value is less than or equal to a threshold value, and the bit length value fails to satisfy the first condition when the bit length value greater than the threshold value;
• performing the selected polar code encoding method on an input bit sequence having a K bit length to obtain an encoded bit sequence having an N bit length, wherein K is a positive integer, and N is a positive integer greater than or equal to K;
• determining, from the encoded bit sequence, a bit sequence to be transmitted;
• and
• transmitting, to a receiver, a message comprising the bit sequence.

A non-transitory storage medium having code stored thereon, the code upon execution by a processor, causing the processor to implement a method of wireless communication comprising:

• determining a polar code encoding method according to a data characteristic of an information bit sequence, the data characteristic of the information bit sequence comprising a bit length value of the information bit sequence and a link direction of the information bit sequence, wherein the polar code encoding method comprises a parity-check polar code encoding or a cyclic redundancy check-aided polar code encoding, wherein in a first case that the bit length value satisfies a first condition, the parity-check polar code encoding is selected, and wherein the bit length value satisfies the first condition when the bit length value is less than or equal to a threshold value, and the bit length value fails to satisfy the first condition when the bit length value greater than the threshold value;
• performing the selected polar code encoding method on an input bit sequence having a K bit length to obtain an encoded bit sequence having an N bit length, wherein K is a positive integer, and N is a positive integer greater than or equal to K;
• determining, from the encoded bit sequence, a bit sequence to be transmitted;
• and
• transmitting, to a receiver, a message comprising the bit sequence.
