Problems solved by technology

[0003] In the Internet of Vehicles system, duplicate data transmission can be performed in a carrier aggregation (Carrier Aggregation, CA) scenario, or based on a short transmission time interval (short Transmission Time Interval, sTTI) transmission service. However, whether to perform data replication services and sTTI The transmission service is determined by the terminal equipment, and the network equipment cannot directly obtain this information when performing resource scheduling, and thus cannot achieve reasonable resource scheduling.

Embodiment Construction

[0077] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0078] It should be understood that the technical solutions of the embodiments of the present application can be applied to the IoV system, and the IOV system can be based on various communication systems, for example, the IOV system based on LTE-D2D. Different from the way in which the communication data between terminals in the traditional LTE system is received or sent through network equipment (for example, base stations), the Internet of Vehicles system adopts the way of terminal-to-terminal direct communication, so it has higher spectral efficiency and lower transmission delay.

[0079] Optionally, the communication system based on the Internet of Vehicles system may be a Global System of Mobile communication (GSM) system, a Code Division Multiple Access (CDMA) system,...

Abstract

The present application provides a data transmission method, terminal equipment, and network equipment. After the network equipment learns that the terminal equipment needs to perform data replication service and / or sTTI transmission service, it can configure logical channels accordingly, and then realize reasonable scheduling of resources. . The method includes: sending status information to the network equipment, the status information indicating that the terminal equipment needs to perform target services, and the target services include data duplication services and / or sTTI transmission services.

Description

technical field [0001] The present application relates to the communication field, and more specifically, relates to a data transmission method, a terminal device and a network device. Background technique [0002] The Internet of Vehicles or Vehicle to Everything (V2X) communication system is a sidelink (SideLink, SL) transmission technology based on Device to Device (D2D) communication, which is different from the traditional long-term evolution (LTE) In the Long Term Evolution (LTE) system, the communication data is received or sent by the base station in different ways. The Internet of Vehicles system adopts the terminal-to-terminal direct communication method, so it has higher spectral efficiency and lower transmission delay. [0003] In the Internet of Vehicles system, duplicate data transmission can be performed in a carrier aggregation (Carrier Aggregation, CA) scenario, or based on a short transmission time interval (short Transmission Time Interval, sTTI) transmiss...
