Assignee: LG ELECTRONICS INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 4:
5. A wireless device in a wireless communication system comprising:
a transceiver;
a memory;
and at least one processor operatively coupled to the transceiver and the memory, and configured to:
receive, from a Master Node (MN), a radio resource control (RRC) reconfiguration message fora Primary Cell (PCell) on a first frequency, wherein the PCell is included in a Master Cell Group (MCG);
receive, from a Secondary Node (SN), an RRC reconfiguration message for a Secondary Cell Group (SCG) on a second frequency, wherein a SCell is included in an SCG;
configure a split bearer for the PCell and the SCG cell,
wherein a Packet Data Convergence Protocol (PDCP) entity is configured for the split bearer, and
wherein a first Radio Link Control (RLC) entity for the PCell and a second RLC entity for the SCG cell is configured for the split bearer;
activate packet duplication in the PDCP entity associated with the first RLC entity and the second RLC entity;
submit a first duplicated data both to the first RLC entity and the second RLC entity;
transmit the first duplicated data both to the PCell through the first RLC entity and to the SCG cell through the second RLC entity; and
perform measurements of a congestion level on the first frequency and the second frequency;
based on the congestion level of the first frequency is equal to or greater than a threshold:
deactivate the packet duplication on the PDCP entity;
submit a second data only to the second RLC entity; and
transmit the second data only to the SCG cell through the second RLC entity.
