    Abstract: Aspects described herein relate to resource allocation in an integrated access and backhaul (IAB) system. A central unit (CU) transmits over a backhaul link a message to a distributed unit (DU) including a resource configuration for a DU cell and a child cell corresponding to a child node served by the DU cell. The DU determines that the message misidentifies the child cell using an ID of a different cell. In response to that determination, the DU communicates with the child node based on the resource configuration specific to the misidentified child cell. Using this coordinated technique enables the CU to provide the DU with a child-node specific resource configuration to enable the DU to use this configuration for communicating with the child node. This maximizes efficiency in multi-node communications between one or more child nodes and cells while adding minimal, if any, signaling overhead.

    Abstract: Method and apparatus to rewrite BAP headers in IAB networks. The apparatus receives, from a second base station, a routing configuration indicating a mapping between a first routing ID and a second routing ID. The apparatus receives a packet with a packet header indicating the first routing ID. The apparatus determines the second routing ID based on the routing configuration mapping the first routing ID in the packet header to the second routing ID. The apparatus modifies, based on a determination of the second routing ID, the packet header to replace the first routing ID with the second routing ID. The apparatus transmits the packet based on the second routing ID.
