The invention discloses a method for transmitting a data packet in a mobile communication system, which comprises the following steps: segmenting a service data unit (SDU) and processing the segmented SDU to generate one or more protocol data units (PDUs); aligning the PDUs in bytes and dividing the PDUS into one or more transmission blocks of the same length which can be just transmitted by physical channel resources allocated in a radio frame respectively; and when the data payloads of the last segment are insufficient to fill the whole segment, filling bits at the tail of the segment to make the segment as long as other segments, and indicating the transmission formats of the transmission blocks by using a uniform data packet header. When the method is applied to the data packet transmission in the mobile communication system, particularly a narrow-band communication system, complete data transmission can be completed by less indication information, less physical transmission resources are occupied, and the data transmission efficiency can be improved effectively.
