1. A communication method of a wireless backhaul network, wherein the method is applied to a UE performing data communication based on a wireless backhaul network, the wireless backhaul network comprises: at least one tree topology structure, each of the at least one tree topology structure comprises a serving base station node and at least one relay node, wherein a root of the tree topology structure is the serving base station node; a relationship between any two nodes in the wireless backhaul network is a child-parent relationship or non-child-parent relationship, and the any two nodes with the child-parent relationship communicate through a wireless connection; wherein each relay node in the tree topology structure has a unique parent node; when the UE, accesses from one of the at least one relay node of the wireless backhaul network, a path for data communication between the UE and the service base station node is uniquely determined as: a path from the one relay node to the serving base station node through parent nodes in turn;
wherein the method comprises:
accessing, by the UE, an access node of the wireless backhaul network;
sending an access request to the access node, so that the access node transmits the access request to the serving base station node via a path between the access node and the serving base station node;
receiving, by the UE, an access response and a service transmission path;
reporting, by the UE, a measurement report in a process of performing service transmission with the serving base station node based on the service transmission path; wherein the service transmission path is a current path that is uniquely determined between the UE and the service base station node; and
receiving, by the UE, a new service transmission path configured by and sent from the serving base station node.
