Abstract

A technique for performing layer 2 processing is described. In a method implementation of this technique, at least one first RLC SDU is created from one or more first RLC PDUs. It is assumed here that the first RLC SDU belongs to an incomplete RLC SDU set that is to comprise at least one second RLC SDU, and that the second RLC SDU is to be created from at least one second RLC PDU not yet available. In a next step, a first PDCP function is applied to the first RLC SDU to create a data packet. The RLC function is only performed after the second RLC PDU has become available (or after an RLC time-out). Then, after the RLC function has been performed, the data packet is released to a second PDCP function.
