Kind Code:
A1
Abstract:
The present application relates to the technical field of communications. Provided are a communication method and apparatus. The method comprises: a first IAB node receiving first information, wherein the first information comprises a first random access resource; on the first random access resource, a mobile terminal (MT) of the first IAB node sending a first random access request to a second IAB node, wherein the first random access request is used for the MT of the first IAB node to request access to a distributed unit (DU) of the second IAB node, and the second IAB node is a subnode of the first IAB node. In this way, a connection between the MT of the first IAB node and the DU of the second IAB node can be established, which is equivalent to adding a backhaul link between the first IAB node and the second IAB node, thus improving the reliability of a system where the first IAB node and the second IAB node are located.
