Abstract
A method performed by a network node for transmission of a Packet Data Convergence Protocol, PDCP, Protocol Data Unit, PDU, to a wireless communications device is provided. The network node and the wireless communications device operate in a wireless communications network. The network node arranges (505) a number of PDCP PDUs in a numerical order based on their respective PDCP Sequence Number, SN. The number of PDCP PDUs is taken from a first set of PDCP PDUs comprising one or more first time transmitted PDCP PDUs and from a second set of PDCP PDUs comprising one or more retransmitted PDCP PDUs. The one or more first time transmitted PDCP PDUs and the one or more retransmitted PDCP PDUs are received from a controlling node. The network node transmits (506) the number of the PDCP PDUs in the numerical order to the wireless communications device 120.
