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

Claim 5:
6. A processor for a wireless device in a wireless communication system, wherein the processor is configured to control the wireless device to perform operations comprising:
receiving, from a Master Node (MN), a radio resource control (RRC) reconfiguration message for a Primary Cell (PCell) on a first frequency, wherein the PCell is included in a Master Cell Group (MCG);
receiving, 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;
configuring 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;
activating packet duplication in the PDCP entity associated with the first RLC entity and the second RLC entity;
submitting a first duplicated data both to the first RLC entity and the second RLC entity;
transmitting the first duplicated data both to the PCell through the first RLC entity and to the SCG cell through the second RLC entity; and
performing 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:
deactivating the packet duplication on the PDCP entity;
submitting a second data only to the second RLC entity; and
transmitting the second data only to the SCG cell through the second RLC entity.
