Abstract  Abstract

The present invention relates to a mobile communication system supporting packet services, and more particularly, to a method and apparatus for transmitting and receiving packet data for efficiently using radio resources by reducing a header size of a protocol data unit (PDU) on a radio link. The RLC layer configures an RLC PDU without inserting information indicating a start position and an end position or padding of a service data unit (SDU) included, and indicates a length indicator included in a header of the RLC PDU. It is set to a value indicating that the intermediate segment of the SDU. In this way, the present invention reduces the size of overhead caused by packet transmission and efficiently uses the limited radio resources.
