Abstract: Data transmission methods and apparatuses for wireless backhaul networks are described. A wireless backhaul node determines one or more reporting nodes for a data volume of a first-type data packet from a plurality of next-hop nodes of the wireless backhaul node on an uplink based on the data volume of the first-type data packet, a data volume of a second-type data packet, and a data volume of a third-type data packet. The wireless backhaul node sends, to the one or more reporting nodes, a buffer status report used to indicate the data volume of the first-type data packet. At least one of the first-type data packet, the second-type data packet, and the third-type data packet includes a data packet from an adaptation layer entity of the wireless backhaul node and/or a data packet from a radio link control layer entity of the wireless backhaul node.

Abstract: Example information transmission methods and apparatus are described. One example method includes determining first information by a relay node, where the first information includes at least one of the following information: a buffer status at a granularity of the relay node, a buffer status at a granularity of an RB between the relay node and at least one first node, a buffer status at a granularity of each first node in the at least one first node, and a buffer status at a granularity of an RB between each first node in the at least one first node and a child node, where the at least one first node is a child node of the relay node. A first packet that carries the first information is sent by the relay node to a second node.

Abstract: This application relates to the field of communications technologies, and provides a link maintenance method and an apparatus in a relay system, to reduce a service interruption latency, or to avoid service congestion. The method includes: determining, by a first node, one or more candidate neighboring nodes to be measured; measuring, by the first node, the one or more candidate neighboring nodes; determining, by the first node based on a measurement result, whether to establish or delete a backup backhaul link between the first node and the one or more candidate neighboring nodes; and sending, by the first node, a request to a second node, where the request is used to request the second node to establish or delete the backup backhaul link between the first node and the one or more candidate neighboring nodes.

Abstract: This application provides a communication method and an apparatus. UE establishes a connection to a home access gateway by using CPE, the home access gateway sends configuration information of a first link and configuration information of a second link to the CPE, and sends the configuration information of the second link to the UE. The first link is a link between the CPE and the home access gateway, the second link is a link between the CPE and the UE, the configuration information of the first link is used to indicate quality of service QoS information of the first link, and the configuration information of the second link is used to indicate QoS information of the second link. The UE and the CPE ensure, based on respective configuration information, QoS of UE service data transmitted on the first link and the second link.
