Abstract: Methods and apparatuses are provided in a wireless communication system. A radio link control (RLC) protocol data unit (PDU) is obtained from a lower layer. A status PDU is generated based on the RLC PDU. The status PDU includes a first field indicating a sequence number (SN) of an RLC data unit identified as lost, a second field indicating a number of consecutively lost RLC data units starting from and including the SN, and a third field indicating whether the second field follows the first first field. The status PDU is delivered to the lower layer.
