Abstract
The method for a user equipment (UE) performing cell activation comprises receiving a duplication activation command for a first duplicate radio bearer (RB); activating duplication for the first duplicate RB based on the duplication activation command; and activating a first cell mapped to the first duplicate RB if the first cell is deactivated.
Claims13
A method for a user equipment (UE) performing cell activation, the method comprising:
- receiving a duplication activation command for a first duplicate radio bearer (RB);
- activating duplication for the first duplicate RB based on the duplication activation command;
- and
- activating a first cell mapped to the first duplicate RB if the first cell is deactivated,
- wherein a packet data convergence protocol (PDCP) entity of the first duplicate RB submits a duplicated PDCP protocol data unit (PDU) of the first duplicate RB to a RLC entity mapped to the first duplicate RB only after all cells mapped to the first duplicate RB is activated.

A user equipment (UE) for performing cell activation, the UE comprising:
- a receiver configured to receive a duplication activation command for a first duplicate radio bearer (RB);
- and
- a processor configured to:
- activate duplication for the first duplicate RB based on the duplication activation command;
- activate a first cell mapped to the first duplicate RB if the first cell is deactivated;
- and control a packet data convergence protocol (PDCP) entity of the first duplicate RB to submit a duplicated PDCP protocol data unit (PDU) of the first duplicate RB to a RLC entity mapped to the first duplicate RB only after all cells mapped to the first duplicate RB is activated.
