Abstract
A method and an apparatus for transmitting a data packet are provided. A user equipment UE determines that service data unit SDU delivery needs to be performed for an erroneous data packet born on a radio bearer RB of a service. If the received data packet is not received correctly after maximum retransmission times are achieved, the UE determines that a received data packet is the erroneous data packet. The UE delivers the SDU in the erroneous data packet to a radio link control RLC entity corresponding to the RB, and the RLC entity in the UE sends the SDU to an upper layer of the RLC entity. The delivery of the erroneous data packet may be achieved, so that an air interface resource may be effectively utilized and the decoding quality may be improved.
