S202:UE sends MAC-iPDU to base station.

The MAC-iPDU of generation is sent to base station by UE.

In the present embodiment, UE, according to pre-conditioned, generate MAC-iPDU, UE and sends MAC-iPDU to base station.Namely different pre-conditioned under, the MAC-iPDU of generation has different data packet formats, and this data packet format compared to existing technology in data packet format header overhead little, thus can efficiency of transmission be improved.

In the above-described embodiments, pre-conditioned difference, the form of MAC-iPDU that UE generates is also different, illustrate below three kinds different pre-conditioned under, the concrete form of the MAC-iPDU that UE generates.

The first is pre-conditioned: UE generates the RLCPDU presetting size at rlc layer.

Particularly, the condition of the transmission situation of eating dishes without rice or wine can be predicted at rlc layer under, rlc layer generates the RLCPDU presetting size and refers to that the RLCPDU that rlc layer generates can be converted into MAC-isSDU, does not need the segmentation carrying out packet at MAC-is layer, thus can save segmentation instruction.

This pre-conditioned under, the concrete form of MAC-iPDU is: MAC-iPDU comprises head and the MAC-isPDU of MAC-iPDU; Each MAC-isPDU comprises MAC-isSDU.
