摘要
Embodiments include exemplar)′ methods and/or procedures performed by a central unit, CU, (110) that together with first and second distributed units, DUs (120, 130), comprise a node (100, 1160) of a wireless communication network. Embodiments include receiving (830) from the first DU, prior to occurrence of a first event concerning a user equipment, UE, (1110) that is in communication with the first DU, a lower-layer configuration of the UE. Embodiments also include storing (840) the lower-layer configuration of the UE, and sending (870), to the second DU, a setup request comprising the stored lower-layer configuration of the UE. Embodiments also include receiving (880), from the second DU, a setup response comprising a first delta configuration indicating one or more differences between a lower-layer configuration of the second DU and the stored lower-layer configuration. Embodiments also include sending (890), to the first DU, a modification request comprising the first delta configuration. Other embodiments include corresponding methods and/or procedures performed by first or second DUs, as well as CUs or DUs configured to perform operations of the exemplary methods and/or procedures.
