Abstract: Methods and apparatuses are provided in a wireless communication system. A service data unit (SDU) is received from an upper layer. A protocol data unit (PDU) including a header for the SDU is generated based on an expiry of a timer for the SDU or an indication obtained from the upper layer. The PDU including the header is delivered to a lower layer. The PDU includes only the header and does not include a payload.
