ENHANCED ADMISSION CONTROL IN INTEGRATED ACCESS AND BACKHAUL (IAB)

Abstract:

Aspects of the present disclosure provide techniques for admission control in a network (e.g., an Integrated Access and Backhaul (IAB) network). Certain aspects provide a method for wireless communication by a first base station (BS). The method generally includes sending, to an IAB-node, a request message requesting to setup or modify a context for a child node of a first logical IAB-distributed unit (DU) of the IAB-node, wherein the first logical IAB-DU is associated with the first BS, sending an indication to the IAB-node that the child node is currently served by the IAB-node at a second logical IAB-DU of the IAB-node, wherein the second logical IAB-DU is associated with a second BS, and receiving an acknowledgment message from the IAB-node based at least in part on the indication to the IAB-node.
