摘要： The present disclosure relates to a method performed by a radio device. The method comprises receiving a plurality of Protocol Data Units (PDU) 41 of a PDU sequence 40 over a radio interface. The method also comprises detecting that a PDU 41b of the sequence of the received PDUs is missing. The method also comprises, for each of the received PDUs, identifying which Service Data Unit(s) (SDU) 51 it relates to. The method also comprises, based on said identifying, determining that a complete SDU 51b is obtainable from one or several PDUs of the received PDUs, which one or several PDUs are later in the sequence of the received PDUs than the missing PDU. The method also comprises obtaining the complete SDU from said one or several PDUs. The method also comprises performing a packet inspection of the obtained complete SDU to determine the type of data it carries. The method also comprises, based on the performed packet inspection, determining that the complete SDU fulfils a predetermined criterion. The method also comprises delivering the complete SDU which fulfils the predetermined criterion to a higher layer in the radio device, before receiving a retransmission of the PDU which is missing.
