*This abstract for appeared for patent application  number 18017756 Titled 'HANDLING OF BUFFERED TRAFFIC DURING INTER-CU MIGRATION OF AN ANCESTOR INTEGRATED ACCESS BACKHAUL (IAB) NODE'

==Simplified Explanation==

The abstract describes methods performed by a network node in an Integrated Access Backhaul (IAB) network. The network node is the ancestor of another network node and is responsible for handling data associated with the second network node. The methods involve determining when the second network node is migrating from one centralized unit (CU) to another CU. Once this migration is detected, the first network node modifies how it handles buffered data related to the second network node. This includes handling uplink (UL) data buffered at the first network node, downlink (DL) data buffered at the first network node, and UL data buffered at child nodes of the first network node. The abstract also mentions that there are complementary methods for the first CU and that network nodes in the IAB network are configured to perform these methods.


==Original Abstract Submitted==

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.
