Abstract: A method for polar encoding is provided in this application. The method comprises: receiving a message comprising information bits; encoding the message using a first polar code to obtain a first codeword; encoding the message using a second polar code to obtain a second codeword, wherein the second codeword includes two parts, and the first part of the second polar code is same as the first polar code; transmitting the first codeword to a receiver in a first transmission; and transmitting the second part of the second codeword in a second transmission without transmitting the first part of the second codeword when the receiver is unable to decode the message based on the first codeword.
