Abstract: A data packet transmission method and apparatus are provided. The method includes: An IAB donor determines first configuration information, where the first configuration information is used to indicate a first backhaul link BH RLC channel, and the first BH RLC channel is used to transmit a control protocol data unit PDU at a backhaul adaptation protocol BAP layer. The IAB donor sends the first configuration information to an IAB node. According to the foregoing procedure, the IAB donor indicates, by using the first configuration information, the IAB node to send the control PDU at the BAP layer through the first BH RLC channel, to implement bearer mapping when the IAB node needs to send the control PDU at the BAP layer.

Abstract: The present invention provides a communications method and apparatus. The method includes: when an integrated access and backhaul IAB node detects that an RLF occurs on a first backhaul BH link, triggering, by the IAB node, feedback of DDDS information of the IAB node to an IAB donor node, and/or sending, by the IAB node, first indication information to a child node of the IAB node, where the first indication information is used to indicate the child node of the IAB node to trigger feedback of DDDS information of the child node to the IAB donor node.

Abstract: This application provides a data transmission method and an apparatus. The method includes that an integrated access and backhaul (IAB) donor distributed unit receives downlink data and service attribute information of downlink data that are sent by an IAB donor centralized unit. The IAB donor distributed unit maps the downlink data to a corresponding backhaul radio link control channel (BH RLC) channel based on the service attribute information of the downlink data or based on the service attribute information of the downlink data and access IAB node address information of the downlink data, and sends the downlink data to a next-hop IAB node.

Abstract: The present disclosure discloses example downlink buffer status feedback methods and apparatuses. One example method includes determining first information by a first node, where the first information indicates a downlink buffer status of a first bearer between the first node and a parent node of the first node. The first information is sent by the first node to a second node, where the first node is a relay node in a wireless relay communications system, and the second node is a parent node of the first node.

Abstract: A first terminal obtains a first transmission resource that is sent by an access network device and that is used by the first terminal to send data on a sidelink, where the sidelink is a wireless communication link between the first terminal and a second terminal, and the first transmission resource is a resource of an unlicensed spectrum. The first terminal performs a channel access procedure on the unlicensed spectrum. The first terminal sends first information to the access network device when the first terminal determines that a failure occurs in the channel access procedure performed on the unlicensed spectrum, where the first information is used to request to allocate a second transmission resource to the sidelink of the unlicensed spectrum.

Abstract: This application provides an example sidelink transmission resource configuration method. Each piece of sidelink data corresponds to one transmission requirement. After obtaining a first data, a terminal device determines a transmission feature of the first resource, and determines, depending on whether reliability of the first resource meets a reliability requirement of the first data, whether to send the first data by using the first resource.
