Abstract
The method for a user equipment (UE) performing packet duplication comprises receiving a duplication activation command for a duplicate radio bearer (RB); and applying the packet duplication for the duplicate RB if each of transmission paths of the duplicate RB is mapped to at least one activated cell.
Claims8
A method for a user equipment (UE) performing packet duplication, the method comprising:
- receiving a duplication activation command for a duplicate radio bearer (RB);
- and
- checking whether both of transmission paths of the duplicate RB are mapped to at least one activated cell;
- applying the packet duplication for the duplicate RB based on both of the transmission paths of the duplicate RB is mapped to at least one activated cell;
- and
- stopping the packet duplication for the duplicate RB based on one of the transmission paths of the duplicate RB not being mapped to at least one activated cell,
- wherein the duplicate RB is associated with a Packet Data Convergence Protocol (PDCP) entity and two Radio Link Control (RLC) entities,
- wherein each of the two RLC entities is mapped to a different cell, and
- wherein the PDCP entity of the duplicate RB transmits a packet to another transmission path where at least one cell is activated based on one of the transmission paths of the duplicate RB not being mapped to at least one activated cell.

A user equipment (UE) for performing packet duplication, the UE comprising:
- a receiver configured to receive a duplication activation command for a duplicate radio bearer (RB);
- and
- a processor configured to:
- check whether both of transmission paths of the duplicate RB are mapped to at least one activated cell;
- apply the packet duplication for the duplicate RB both of the transmission paths of the duplicate RB being mapped to at least one activated cell;
- and
- stop the packet duplication for the duplicate RB based on one of the transmission paths of the duplicate RB not being mapped to at least one activated cell,
- wherein the duplicate RB is associated with a Packet Data Convergence Protocol (PDCP) entity and two Radio Link Control (RLC) entities,
- wherein each of the two RLC entities is mapped to a different cell, and
- wherein the PDCP entity of the duplicate RB transmits a packet to another transmission path where at least one cell is activated based on one of the transmission paths of the duplicate RB not being mapped to at least one activated cell.
