    • The present disclosure describes a method, an apparatus, and a computer readable medium for hybrid automatic repeat request (HARQ) transmissions. For example, the method may include generating a first codeword for a first information block, wherein the first codeword is a first polar code, and wherein the first information block includes cyclic redundancy check (CRC) bits; transmitting the first codeword to a receiver; determining that the first polar code is not successfully decoded at the receiver based at least on a first message received from the receiver; generating a second codeword for a second information block, wherein the second codeword is a first enhanced polar code, and wherein the second information block does not include any CRC bits; transmitting the second codeword to the receiver; and determining that the second codeword and the first codeword are successfully decoded at the receiver based at least on a second message received from the receiver.
    • 本公开描述了一种用于混合自动重传请求(HARQ)传输的方法,装置和计算机可读介质。 例如,该方法可以包括:生成用于第一信息块的第一码字,其中第一码字是第一极性码,并且其中第一信息块包括循环冗余校验(CRC)比特; 将第一码字发送到接收机; 至少基于从所述接收器接收到的第一消息,确定所述第一极性码未在所述接收器处被成功解码; 产生用于第二信息块的第二码字,其中所述第二码字是第一增强极性码,并且其中所述第二信息块不包括任何CRC比特; 将第二码字传送给接收机; 以及至少基于从所述接收器接收的第二消息,确定所述第二码字和所述第一码字在所述接收器处被成功解码。
