Abstract

An MBS (master base station), UE (user equipment) and method operate using dual connectivity where the UE is connected to an MBS and a SBS (secondary base station). Capability information is transmitted to the MBS by the UE and indicates whether the UE supports a SCG (Secondary Cell Group) bearer and whether the UE supports a split bearer split in a PDCP (Packet Data Convergence Protocol) layer of the MBS. The UE receives from the MBS a message configuring, but not simultaneously configuring, either the SCG bearer or the split bearer to the UE. Radio protocols of the SCG bearer are only located in the SBS, and radio protocols of the split bearer are located in both the MBS and the SBS. One split path of the split bearer goes via the SBS and another split path of the split bearer goes via the MBS and not via the SBS.
