Abstract: This application provides a packet sending method, an apparatus and a chip. The method is applied to a terminal, the terminal includes a baseband processor, an application processor, and a communications interface. The baseband processor reports information about a first packet to the application processor, where the first packet is a to-be-sent packet discarded by the baseband processor. The application processor transmits a second packet to the baseband processor according to the information about the first packet, where the second packet is the same as the first packet. The baseband processor sends the second packet to a network device by using the communications interface.

Abstract: The present invention discloses a packet transmission method and user equipment. The method includes: transmitting, by a sending node, multiple packets to a receiving node; receiving multiple acknowledgement packets from the receiving node; after determining, based on the received multiple acknowledgement packets, that a first packet is lost, retransmitting the first packet; and if it is detected that the retransmitted packet is lost, continuously retransmitting, by the sending node, the first packet to the receiving node in a preset time interval for at least twice. According to the solutions of the present invention, the retransmitted packet can be detected and recovered in time after the retransmitted packet is lost, thereby reducing a quantity of times of timeout retransmission, improving a transmission rate, moreover, reducing a packet loss probability of a retransmitted packet, and further reducing a probability of timeout retransmission.
