Abstract
The embodiments of the present application provide a wireless backhaul network, a communication method and an apparatus. The wireless backhaul network comprises at least one tree topology structure, each of the at least one tree topology structure being composed of a serving base station node and at least one relay node, the root of the tree topology structure being the serving base station node; and any two nodes in the wireless backhaul network are in a child-parent relationship or non-child-parent relationship, and any two nodes, which are in the child-parent relationship, communicate by means of wireless connections.
Claims16
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.
