Abstract: Embodiments of the present disclosure relate to routing in integrated access and backhaul (IAB) communication. According to embodiments of the present disclosure, two or more IAB donors share topology information for inter IAB network routing. The IAB donors allocate addresses to IAB nodes with dual connectivity based on the topology information. In this way, it avoids address collisions when routing in the inter IAB networks.

Abstract: Systems, methods, apparatuses, and computer program products for informing a multi-connectivity master node of an impending wrap around of packet counter value are provided. One method includes receiving, from a nodehosting packet data convergence protocol (PDCP) for a data radio bearer (DRB), a counter check request including a count value, and determining that the count value is approaching its maximum value. In response to the determining, the method may further include initiating release of the data radio bearer (DRB) and optionally adding a new bearer.
