Document Type and Number:
WIPO Patent Application WO/2019/101162
Kind Code:
A1
Abstract:
A method for multi-connectivity is provided. The method includes: receiving, by a User Equipment (UE), a first Radio Resource Control (RRC) message comprising at least one Secondary Cell Group (SCG) Data Radio Bearer (DRB) configuration from a Master Cell Group (MCG), and reporting, by the UE, failure information to the MCG via a second RRC message, wherein the failure information comprises an SCG failure cause value and at least one first cell identity (ID).
