Abstract  Abstract

A method and apparatus for transmitting control information relating to an uplink packet data service from an UE to a Node B in a mobile communication system are provided. MAC-es protocol data units (PDUs) including uplink packet data and a control service data unit (SDU) including the control information are multiplexed and contained in a MAC-e PDU. In a header of the MAC-e PDU a header part corresponding the control SDU contains a data description indicator (DDI) field set as a specific value representing that the control information is transmitted and a header part corresponding to the MAC-es PDU contains a DDI field which represents a MAC-e flow and a logical channel relating to the uplink packet data and a data size. Node B detects the control information from the control SDU based on the DDI field set as the specific value.
