    Abstract: Embodiments of the present invention provide a network device and a data backhaul implementation system and method, which can implement centralized and dynamic allocation of backhaul resources in a network and improve a data backhaul capacity of the entire network. The method includes: obtaining, according to channel state information, a backhaul request of a second network device, and residual backhaul capability information of a third network device, backhaul control information used for controlling the second network device and the third network device to backhaul data, where the backhaul control information includes backhaul network topology control information and physical resource allocation information;and sending the backhaul control information to the second network device and the third network device, so that the second network device and the third network device backhaul data according to the backhaul control information.

    Abstract: When receiving a first data frame sent by a transmitting apparatus, a receiving apparatus may return error indication information including an identifier of at least one erroneous codeword group to the transmitting apparatus if it is found that an error occurs in an initial codeword of the first data frame. The transmitting apparatus may obtain the erroneous codeword group and encode the erroneous codeword group, and retransmit a part of a sub check codeword obtained through encoding to the receiving apparatus. The receiving apparatus may obtain a third check matrix based on a first check matrix, a second check matrix, and a location of the at least one erroneous codeword group in the initial codeword, and re-decode the retransmitted partial sub check codeword and content of the first data frame together based on the third check matrix, so as to obtain a correct initial codeword.
