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: This application provides a flow control method and apparatus, and relates to the field of communications technologies. A relay device indicates flow control to an upper-level node to avoid spectrum resources waste because of excessively small amount of data transmission or an excessively large amount of data transmission from an upper-level node. The method includes: A first node determines to indicate a second node to perform flow control; and the first node sends a first flow control indication to the second node. The first flow control indication is carried in adaptation layer control signaling, an RLC control message, or a MAC CE. The first flow control indication includes identifiers of one or more bearers and flow control information. The second node is a relay node or a donor base station.

Abstract: A communication method and apparatus, and a computer-readable storage medium are provided. A first access network device sends, to a first relay device, first indication information indicating whether access of a mobile relay device is allowed. When the first relay device is a mobile relay device, the first relay device sends an access request to a second access network device that allows access of a mobile relay device, so that a mobile relay device initiates an access request to an access network device that allows access of a mobile relay device, ensuring normal access of the mobile relay device.

Abstract: This application provides a communication method. In the method, a first node receives a first radio resource control (RRC) reconfiguration message from a first donor node through a second node. After the first node receives the first RRC reconfiguration message from the second node, the first node receives first indication information from the second node. When the first node determines, based on the first indication information, that the first RRC reconfiguration message becomes effective, the first node establishes an RRC connection to a second donor node based on the first RRC reconfiguration message. In the method, the first node and the second node are nodes in a group that performs group handover, the group handover is a cross-donor node group handover, the second node is a head node or the second node is connected to a head node, and the second node is a parent node of the first node.

Abstract: Embodiments of this application relates to a communication method and a related device. In an example, a device receives a first data packet in a first network segment, the first data packet comprises a first backhaul adaptation protocol (BAP) routing identity, and the first BAP routing identity is used for transmission of the first data packet in the first network segment. The device further obtains a first correspondence. In response to determining that the first correspondence comprises the first BAP routing identity in the first data packet, the device determines that the first data packet meets a preset condition. In response to that the first data packet meets the preset condition, the device replaces the first BAP routing identity in the first data packet with a second BAP routing identity according to the first correspondence, to obtain a second data packet.

Abstract: Embodiments of this application provide a lossless data transmission communication method, apparatus, and system. The method includes: A first network node determines a first data packet. A destination node of the first data packet is a third network node or a security gateway on the third network node side. The third network node is a source donor node or a source donor node central unit (CU) of the first network node. The first network node sends the first data packet to a second network node. The second network node is a target donor node distributed unit DU of the first network node. According to the method, a data packet loss in a topology update process of the first network node can be avoided, and service continuity can be ensured.
