Discarding a Duplicate Packet of an RLC Entity in Response to an Acknowledgement

摘要

A wireless device receives an indication for activation of packet data convergence protocol (PDCP) packet duplication of a radio bearer associated with a first radio link control (RLC) entity and a second RLC entity. A packet of the radio bearer is duplicated. The packet to the first RLC entity is provided. A duplicate packet to the second RLC is provided. The packet of the first RLC entity is transmitted. An acknowledgement of a successful delivery for the packet of the first RLC entity is received. In response to the acknowledgement, the duplicate packet of the second RLC entity is discarded.
