[0028] The present invention will be further described below through specific embodiments.
[0029] Reference image 3 , Figure 4 with Figure 5 , A method for transmitting data packets in a mobile communication system. The service data unit SDU is segmented and processed to generate one or more segments of protocol data unit PDUs, and then the PDUs are divided into byte alignment and can be allocated in a wireless frame. When the data payload of the last segment is not enough to fill the entire segment, add padding bits at the end of the segment to make the length of the segment equal to The other segments are the same, and a unified data packet header is used to indicate the transmission format of these transmission blocks. It includes the following steps:
[0030] ①Segment the business data unit SDU;
[0031] ②Add CRC to the SDU segment to generate PDU;
[0032] ③According to the physical channel resource carrying bit length corresponding to a radio frame, calculate the padding bi
