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: A communication method includes a first IAB node receives a first message from a CU of an IAB donor, where the first message indicates the first IAB node to be handed over from a first parent node to a second parent node, and the first message includes a first IP address of the first IAB node. The first IAB node determines first transport network layer association information between the first IAB node and the CU of the IAB donor based on the first IP address. The first IAB node updates control plane context information of an F1 interface by using the first transport network layer association information, where the F1 interface is an interface between the first IAB node and CU of the IAB donor. An IAB node communicates with a CU of an IAB donor by using a first IP address as soon as possible after handover is completed.

Abstract: Examples in this application provide an identifier management method and apparatus. One example method includes receiving, by a first donor node, first indication information sent by a first node, where the first indication information indicates that the first node can be configured to provide a wireless backhaul service, and sending, by the first donor node to the first node, a first identifier, where the first identifier uniquely identifies the first node on a wireless backhaul link within a service range of the first donor node.

Abstract: A wireless backhaul method, including: a wireless backhaul device generates a first F1AP message, maps the first F1AP message to a signaling-plane bearer of an LTE Uu interface, and sends the first F1AP message to a primary base station of the wireless backhaul device via the signaling-plane bearer of the LTE Uu interface. The primary base station obtains the first F1AP message via the signaling-plane bearer of the LTE Uu interface, encapsulates the first F1AP message into a first X2AP message, and sends the first X2AP message to a secondary base station of the wireless backhaul device. The secondary base station receives the first X2AP message and obtains the first F1AP message based on the first X2AP message.

CPC classification number: H04W40/248 , H04W40/02
Abstract: A first node sends, after determining that all data packets from a migrating IAB node are received, first indication information to a source IAB donor CU. The first node is an upstream IAB node of a source parent node of the migrating IAB node or is a source IAB donor DU, the source IAB donor CU is an IAB donor CU connected to the migrating IAB node before migration, and the source IAB donor DU is an IAB donor DU connected to the migrating IAB node before the migration. The first node receives second indication information from the source IAB donor CU. The first node updates or releases, based on the second indication information, backhaul configuration information that corresponds to the migrating IAB node and that is on a backhaul link between the first node and a child node of the first node.

Abstract: Example mapping methods and apparatus are described. One example method includes determining a message type of an uplink signaling message by an integrated access and backhaul node. The integrated access and backhaul node maps the uplink signaling message to a corresponding backhaul radio link control (BH RLC) based on an uplink mapping relationship from an integrated access and backhaul donor centralized unit and the message type. The uplink signaling message is sent to a parent node of the integrated access and backhaul node.
