[0043] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0044] The operation content of the hybrid automatic repeat request (HARQ) transmission method based on the puncturing polar code of the present invention is: the signal transmitting end performs a polar coding on the information bit sequence to be sent, and the obtained coded bits are punctured and are Send it into the channel for transmission; the signal receiving end decodes the received signal, and performs a cyclic redundancy code (CRC) check on the decoding result; if the verification is passed, the signal receiving end sends a confirmation to the sending end through the feedback link (ACK) signal; otherwise, send a non-acknowledgment (NACK) signal to the sending end; if the sending end receives the NACK signal, part of the information bits will be sent direc...
