METHOD AND APPARATUS FOR REDUCING TRANSMISSION OVERHEAD

摘要

In a wireless communication system including a wireless transmit/receive unit (WTRU) and an evolved Node B (eNB) capable of transmitting and receiving wireless data, a method and apparatus for reducing transmission overhead includes receiving an upper layer sequence number (SN). The upper layer SN is converted into a radio link control (RLC) service data unit (SDU) SN (SSN). An RLC protocol data unit (PDU) is generated for transmission including an RLC SSN, and incurred transmission overhead is optimized.
