Method and apparatus for transmitting and receiving data via media access control protocol in mobile communication system

摘要

A method and an apparatus for transmitting and receiving data via a MAC protocol in a mobile communication system. The method includes inputting an SDU including transmission data through a logical channel and generating a first PDU that includes the SDU without including multiplexing information for identification of the logical channel, by a first transmission entity; acquiring the first PDU and generating a second PDU including the first PDU in a payload of the second PDU, by a second transmission entity that operates between the first transmission entity and a physical layer; inserting the multiplexing information for identification of the logical channel corresponding to the first PDU into header information of the second PDU; and transmitting the second PDU through the physical layer.
