Abstract

A method for receiving a radio resource control (RRC) message by a user equipment (UE) is described. The method includes receiving, from a base station, a radio resource control (RRC) connection reconfiguration message including data radio bearer (DRB) configuration parameters for remapping a DRB that is established on a master cell group (MCG), to a split DRB; and coupling a packet data convergence protocol (PDCP) that is established on the MCG to a radio link control (RLC) of the MCG and a RLC of a secondary cell group (SCG) based on the RRC connection reconfiguration message.

Claims (16)

1. A user equipment (UE) for receiving a radio resource control (RRC) message, comprising:

a processor; and

memory in electronic communication with the processor, wherein instructions stored in the memory are executable to:

receive, from a base station, a radio resource control (RRC) connection reconfiguration message including data radio bearer (DRB) configuration parameters for remapping a DRB that is established on a master cell group (MCG), to a split DRB; and

couple a packet data convergence protocol (PDCP) that is established on the MCG to a radio link control (RLC) of the MCG and a RLC of a secondary cell group (SCG) based on the RRC connection reconfiguration message.

2. A method by a user equipment (UE) for receiving a radio resource control (RRC) message, comprising:

receiving, from a base station, a radio resource control (RRC) connection reconfiguration message including data radio bearer (DRB) configuration parameters for remapping a DRB that is established on a master cell group (MCG), to a split DRB; and

coupling a packet data convergence protocol (PDCP) that is established on the MCG to a radio link control (RLC) of the MCG and a RLC of a secondary cell group (SCG) based on the RRC connection reconfiguration message.

3. A base station for transmitting a radio resource control (RRC) message, comprising:

a processor; and

memory in electronic communication with the processor, wherein instructions stored in the memory are executable to:

transmit, to a user equipment (UE), a radio resource control (RRC) connection reconfiguration message including data radio bearer (DRB) configuration parameters for remapping a DRB that is established on a master cell group (MCG), to a split DRB; and

cause a packet data convergence protocol (PDCP) that is established on the MCG to be coupled to a radio link control (RLC) of the MCG and a RLC of a secondary cell group (SCG) based on the RRC connection reconfiguration message.

4. A method by a base station for transmitting a radio resource control (RRC) message, comprising:

transmitting, to a user equipment (UE), a radio resource control (RRC) connection reconfiguration message including data radio bearer (DRB) configuration parameters for remapping a DRB that is established on a master cell group (MCG), to a split DRB; and

causing a packet data convergence protocol (PDCP) that is established on the MCG to be coupled to a radio link control (RLC) of the MCG and a RLC of a secondary cell group (SCG) based on the RRC connection reconfiguration message.
