Abstract: This application discloses a configuration method for a network coding function and a related apparatus. The network coding function is implemented on a first access network device. Information needed for a terminal device to perform network coding and/or network decoding is configured by the first access network device, to enable network coding and decoding between the first access network device and the terminal device to be possible. After the network coding function is introduced to an access layer, both latency performance and spectral efficiency performance are considered by transmitting an encoded packet. To be specific, the first access network device may flexibly adjust a quantity of sent encoded packets based on quality of an air interface link, to ensure that the terminal device can successfully perform decoding, reducing a data transmission latency while ensuring service transmission reliability.

Abstract: A communication method and a communication device. A first donor node generates a first data packet, where the first data packet further includes first information. The first information indicates a donor node to which a destination node of the first data packet belongs, or indicates a network segment to which a destination node of the first data packet belongs, or indicates whether a network segment to which a destination node of the first data packet belongs is a network segment controlled by the first donor node. The first donor node sends the first data packet to the destination node first node.

Abstract: An integrated access and backhaul (IAB) node configuration method includes receiving, by a target IAB donor, first information from a source IAB donor. The method also includes sending, by the target IAB donor, first configuration information to the source IAB donor. The first configuration information is for handing over an IAB node from the source IAB donor to the target IAB donor. The IAB node includes a mobile terminal (MT) function and a distributed unit (DU) function. The first configuration information is based on the first information. The first configuration information indicates a transmission direction of a time domain resource configured by the target IAB donor for the MT function. The first information indicates one or more different types of information.

Abstract: A communication apparatus includes a processor coupled to a memory. The memory is configured to store non-transitory instructions. The processor is configured to execute the non-transitory instructions to thereby cause the communication apparatus to perform operations including sending first information to a target integrated access and backhaul (IAB) donor of an IAB node, and receiving second information from the target IAB donor. The first information includes request information useable for setting up a first F1 interface. The second information includes feedback information of the request information. The first F1 interface is a communication interface between a distributed unit (DU) of the IAB node and a central unit (CU) of the target IAB donor. The communication apparatus is a source IAB donor of the IAB node or included in a IAB donor.
