Abstract: A method is provided that a transmitting end generates a data segment, where the data segment includes header information and data parts of a plurality of CBs that are obtained by dividing a TB, there is a position mapping relationship between the data parts of the plurality of CBs and N sub-PDUs included in a MAC PDU, and the header information of each CB indicates a position mapping relationship between the CB and a sub-PDU corresponding to the CB. The transmitting end sends the TB that carries the data segment. Therefore, at a receiving end, if a CRC error occurs on the TB, the receiving end obtains a position of each CB and performs a CRC decision by using a CB as a granularity, to obtain a correct CB. Thereby performance of a wireless communication system is improved.

Abstract: In a method, an IAB donor obtains configuration information of a backhaul radio link control channel BH RLC CH, where the configuration information of the BH RLC CH is configuration information of a BH RLC CH between a first integrated access and backhaul IAB node and a source parent node of the first IAB node. Then, the IAB donor sends the configuration information of the BH RLC CH to a target parent node of the first IAB node.

Abstract: The disclosure provides routing methods and apparatuses. One example method includes that a first node receives a data packet. The first node determines a Backhaul Adaptation Protocol (BAP) header in the data packet, where the BAP header includes a BAP address of a destination node of the data packet and first information. The first information is used to determine whether the BAP header includes a routing path identifier of the data packet. The first node sends the data packet including the BAP header to the destination node based on the BAP header.

Abstract: This application provides a method for determining an association between logical channel groups, including: The first backhaul node receives a first buffer status report from a first device, where the first buffer status report is used to determine uplink buffer statuses of one or more first logical channel groups of a MAC entity corresponding to the first backhaul node and the first device. The first backhaul node determines, based on the one or more first logical channel groups and a first mapping relationship, second logical channel groups associated with the one or more first logical channel groups, where a second device is a parent node of the first backhaul node, and the first mapping relationship includes a mapping relationship between the one or more first logical channel groups and one or more second logical channel groups of a MAC entity corresponding to the first backhaul node and the second device.

Abstract: A data transmission method to implement flexible switching of data transmission between different interfaces, includes: A first terminal obtains a quality of service flow identifier of the first terminal and a QoS parameter of a quality of service flow, where there is a correspondence between the quality of service flow identifier and the QoS parameter of the quality of service flow, and determines, based on the QoS parameter, a logical channel used by the quality of service flow on a PC5 interface. The first terminal maps the quality of service flow to the determined logical channel, and sends the quality of service flow to the second terminal.

Abstract: This application provides example communication methods and example communications apparatuses, to implement bearer mapping for user data transmission. One example method is applied to a wireless backhaul system having a first network and a second network of different RATs. The example method includes obtaining, by a first management network element in the wireless backhaul system, information about a first radio bearer of a terminal in the first network, where the information about the first radio bearer is used to indicate the first radio bearer. The first management network element can then determine a mapping relationship between the first radio bearer and a second radio bearer based on the information about the first radio bearer, where the second radio bearer is a radio bearer of the first device in the second network.
