11. A wireless device comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
receive one or more messages comprising:
configuration parameters for a radio bearer; and
a first information element indicating that packet data convergence protocol (PDCP) packet duplication is configured for transmission of data packets of the radio bearer;
receive a control element indicating activation of the PDCP packet duplication for data packets of the first radio bearer associated with a first radio link control (RLC) entity and a second RLC entity;
duplicate a data packet of the data packets of the radio bearer;
map:
the data packet to a first logical channel associated with the first RLC entity; and
a duplicate data packet to a second logical channel associated with the second RLC entity;
transmit the data packet of the first logical channel associated with the first RLC entity;
receive an acknowledgement for the data packet of the first logical channel associated with the first RLC entity, acknowledging a successful delivery of the data packet; and
in response to the successful delivery of the data packet, discard the duplicate data packet of the second logical channel associated with the second RLC entity.
