Abstract: A data transmission method and a network device are provided. The method includes: obtaining a to-be-transmitted first MAC packet; obtaining a first data control subframe by using field space of a first field of the first MAC packet, and obtaining a first target data subframe based on a second field of the first MAC packet, where the first data control subframe includes a sequence number of the first target data subframe; and transmitting a first frame including the first data control subframe and the first target data subframe to a target network device. A source network device uses space of the first field to generate the first data control subframe used for retransmission control.

Abstract: This application discloses example data encoding methods, data decoding methods, and communication apparatuses. One example data encoding method includes generating M encoding units and distributing the M encoding units to N transmission channels. The M encoding units are obtained by encoding L frames. The M encoding units include at least one first-type unit. A first-type unit of the at least one first-type unit includes a first identifier. The first identifier indicates a start location that is in the first-type unit and that is of a frame header of a first frame in the L frames. M, N, and L are integers greater than or equal to 1.

Abstract: This application relates to the communications field, and discloses an encoding method, a decoding method, an encoding apparatus, and a decoding apparatus. The encoding method includes: receiving a data bitstream; performing forward error correction FEC encoding on the data bitstream to obtain X Reed-Solomon RS outer codes, where each of the X RS outer codes includes N1 symbols, K1 of the N1 symbols are payload symbols; and performing FEC encoding on the X RS outer codes to obtain Y RS inner codes, where each of the Y RS inner codes includes N2 symbols, K2 of the N2 symbols are payload symbols. According to this application, error correction performance of FEC decoding can be improved.

Abstract: This disclosure provides a retransmission method and a communication apparatus, applicable to a wireless or wired communication system. One example method includes: After receiving a signal from a second device, a first device performs first decoding on the signal, then determines whether an error occurs in the signal and a first quantity, and determines, based on a relationship between the first quantity and a first threshold, whether to request the second device to send a first data block, where the first quantity is a quantity of errors that occur in the signal received from the second device, the signal is used to transmit the first data block, and the first threshold is a maximum quantity of errors that can be corrected when the first device decodes the first data block.
