    Abstract: A communication device receives a parallel hybrid automatic repeat request (HARQ) communication instruction, where the parallel HARQ communication instruction is used to instruct the communication device to send or receive data in a parallel HARQ manner, where the sending data in a parallel HARQ manner by the communication device is sending, by the communication device, at least one data packet with same content within a transmission time interval; and the receiving data in a parallel HARQ manner by the communication device is receiving at least one data packet with same content within a transmission time interval, and performing combined decoding on the received at least one data packet with same content; and the communication device sends or receives the data in the parallel HARQ manner according to the parallel HARQ communication instruction. According to the present invention, a delay of data transmission can be reduced.

    Abstract: Methods, systems, and devices for wireless communication are described. A method may include identifying a reference number of tones for an overhead channel of a transport block and segmenting the transport block into a code block based at least in part on the reference number of tones for the overhead channel. In some examples, a code block indicator or the reference number of tones may be transmitted on a control channel. Another method may include receiving a code block size indicator associated with a code block of a transport block, decoding the code block based at least in part on the code block size indicator and assembling the transport block based at least in part on the decoded code block. In some examples, the code block size indicator may be received using a control channel.
