Abstract
The method includes: handing over a first terminal device from a second terminal device to a network device; receiving, by the first terminal device, a first packet data convergence protocol PDCP data packet sent by the network device; and if the first PDCP data packet is a target PDCP data packet, submitting, by the first terminal device, a second PDCP data packet, where the target PDCP data packet is a PDCP data packet sent by the network device based on a transmission status report, and the transmission status report is a status report sent by the first terminal device or the second terminal device to the network device.
Claims17
A data transmission method, comprising:
- handing over a first terminal device from a second terminal device to a network device;
- receiving, by the first terminal device, a first packet data convergence protocol (PDCP) data packet sent by the network device;
- and
- submitting, by the first terminal device, a second PDCP data packet, wherein a target PDCP data packet is a PDCP data packet sent by the network device based on a transmission status report.
A plurality of terminal devices, each of the plurality of terminal devices comprising:
- a processor;
- a memory;
- and
- a transceiver, wherein the memory is configured to store program code, the plurality of terminal devices include a first terminal device and a second terminal device, and the processor of the first terminal device is configured to execute the program code to
- perform a process of handover from a second terminal device to a network device;
- receive, by using the transceiver, a first PDCP data packet sent by the network device;
- and
- submit second PDCP data packet, wherein a target PDCP data packet is a PDCP data packet sent by the network device based on a transmission status report.
A network device, comprising:
- a processor;
- a memory;
- and a
- transceiver, wherein the processor, the memory, and the transceiver are connected to each other, the memory is configured to store program code, and the processor is configured to execute the program code to
- receive, by using the transceiver, a transmission status report sent by a first terminal device or a second terminal device, wherein the transmission status report is used to feed back a receiving status of data that is sent by the network device to the first terminal device by using the second terminal device before the first terminal device is handed over to the network device, and
- after the first terminal device is handed over from the second terminal device to the network device, send, by using the transceiver, a target PDCP data packet to the first terminal device based on the transmission status report.
