GRADUAL MIGRATION IN AN INTEGRATED ACCESS AND BACKHAUL (IAB) NETWORK

Abstract:

Aspects of the present disclosure provide techniques for handover in an Integrated Access and Backhaul (IAB) network or other type of network. One example method which may be performed by a source base station (BS) includes: determining to migrate a child node from a first logical IAB-distributed unit (DU) of an IAB-node to a second logical IAB-DU of the IAB-node, wherein the first logical IAB-DU is associated with the source BS, and wherein the second logical IAB-DU is associated with a target BS; sending, to the target BS, context information of the child node served by the first logical IAB-DU in response to the determination; and indicating, to the target BS, a traffic mapping configuration at the IAB-node associated with the context information and a backhaul connection of the IAB-node.
