Section: 8.2.3.3 Intra-CU topology adaptation procedure in NSA using SCG SRB (SRB3)
Content: This procedure is used when the migrating IAB-MT moves from source parent node to target parent node within the same IAB-donor-CU, when SCG SRB (SRB3) is available for IAB-node during EN-DC operation. The target parent node may use a different IAB-donor-DU than the source parent node. The source path may have common nodes with the target path. The procedure is the same as intra-CU topology adaptation procedure in SA scenario as defined in clause 8.2.3.1 but the UE CONTEXT SETUP REQUEST message includes CG-ConfigInfo in step 3.
