Abstract

A network node 606,608 and a method for Packet Data Convergence Protocol (PDCP) reordering. The network node is operating in a wireless communications network 600. The network node buffers in order one or more first data units received out of order by a PDCP layer, wherein the one or more first data units are received from a lower layer during a first time period, and wherein the lower layer is a layer below the PDCP layer. When the first time period has expired, the network node forwards the one or more buffered first data units in order to an upper layer and starts a second time period. Further, the network node forwards, to the upper layer and in any order, one or more second data units received from the lower layer during the second time period.
