Embodiment 1

[0058] see image 3 , which shows a data transmission method provided by an embodiment of the present invention, the method can be applied to the sending end of the user equipment, and the method can include:

[0059] S301: Based on the configuration information of HARQ retransmission for the data to be transmitted, determine the HARQ retransmission mode of the data to be transmitted;

[0060] S302: According to the HARQ retransmission mode, transmit the data to be transmitted to a user equipment receiving end.

[0061] pass image 3 In the technical solution shown, at the sending end of the user equipment, the HARQ retransmission mode of the data to be transmitted is determined based on the configuration information, and the data to be transmitted is transmitted according to the HARQ retransmission mode, so that there is no need to use HARQ retransmission for all the data to be transmitted Transmission avoids the waste of channel resources and balances the utilization rate ...

Embodiment 2

[0109] Based on the same inventive concept of the foregoing embodiments, see Figure 4 , which shows a data transmission method provided by an embodiment of the present invention, the method is applied to a user equipment receiving end, and the method includes:

[0110] S401: Receive the HARQ transmission mode of the data to be transmitted sent by the user equipment sending end;

[0111] S402: Based on the HARQ transmission mode of the data to be transmitted, receive HARQ retransmission data of the data to be transmitted.

[0112] It can be understood that, for the HARQ transmission mode of the data to be transmitted, the transmitting end of the user equipment may send it in the form of notification information.

[0113] pass Figure 4 In the technical solution shown, the receiving end of the user equipment receives the HARQ retransmission data of the data to be transmitted based on the HARQ transmission mode of the data to be transmitted, thereby avoiding receiving the HARQ...

Embodiment 3

[0133] Based on the same inventive concept of the foregoing embodiments, see Figure 5 , which shows a data transmission method provided by an embodiment of the present invention, the method is applied to a network side device, and the method includes:

[0134] S501: Send configuration information to a user equipment sending end; wherein, the configuration information is used to determine a hybrid automatic repeat request (HARQ) retransmission mode of data to be transmitted.

[0135] Since the sending end of the user equipment determines whether to perform HARQ retransmission according to the configuration information, the sending end of the user equipment does not need to use HARQ retransmission for all data to be transmitted, avoiding the waste of channel resources, and balancing the utilization rate of channel resources and transmission Correct reception rate of data.

[0136] For the technical solution of this embodiment, in the specific implementation process, it may be ...

Abstract

The embodiment of the invention provides a data transmission method and device and a computer storage medium. The method comprises the steps of determining an HARQ retransmission mode of to-be-transmitted data based on configuration information of HARQ retransmission of a hybrid automatic repeat request for the to-be-transmitted data; and transmitting the data to be transmitted to a user equipmentreceiving end according to the HARQ retransmission mode. Through the method of the embodiment of the invention, the data transmission based on the HARQ mechanism is realized for the V2X technology. HARQ retransmission does not need to be adopted for all the to-be-transmitted data, waste of channel resources is avoided, and the channel resource utilization rate and the correct receiving rate of sent data are balanced.

Description

[0001] This application is a branch of an application with an application date of December 21, 2018, an application number of 201880086390.5 (the international application number is PCT / CN2018 / 122888), and an invention titled "A method, device, and computer storage medium for data transmission". case application. technical field [0002] Embodiments of the present invention relate to the technical field of wireless communication, and in particular, to a data transmission method, device, and computer storage medium. Background technique [0003] The Internet of Vehicles system adopts the long-term evolution (LTE, Long Term Evolution)-device-to-device (D2D, Device to Device) sidelink (SL, Sidelink) transmission technology, and the communication data in the traditional LTE system is received through the base station or The transmission method is different. The IoV system adopts the terminal-to-terminal direct communication method, so it has higher spectral efficiency and lower ...
