Abstract
Embodiments include methods performed by a first network node arranged as an ancestor node of a second network node in an Integrated Access Backhaul (IAB) network. Such methods include determining that the second network node is migrating from a first centralized unit (CU) to a second CU and, based on determining that the second network node is migrating from the first CU to the second CU, performing modified handling of buffered data associated with the second network node, including at least one of the following: uplink (UL) data buffered at the first network node, downlink (DL) data buffered at the first network node, and UL data buffered at one or more child nodes of the first network node. Other embodiments include complementary methods for a first CU, as well as network nodes (e.g., IAB nodes, distributed units, CUs) configured to perform such methods.
