Embodiment Construction

[0078] figure 1 In the shown schematic diagram of the wireless communication system architecture, the wireless communication system includes a first terminal, a second terminal, a wireless access device, and a core network device. The first terminal transmits various data with the second terminal through the D2D connection; the second terminal transmits various data with the wireless access device on the licensed spectrum or the unlicensed spectrum through the air interface. Wireless access equipment transmits various data with core network equipment through a tunnel connection.

[0079]In various embodiments of the present application, the first terminal and the second terminal are also referred to as user equipment (user equipment, UE) or mobile station (mobile station), including mobile phones, handheld Internet of Things devices, and wearable devices (wearable devices) wait.

[0080] In each embodiment of the present application, the wireless access device is, for exampl...

Abstract

Embodiments of the present application provide a data transmission method and a corresponding apparatus. In this method, A D2D terminal or a D2D terminal transmit packets sent to a device carry the same quality of service stream QoS flow that provides the same service in a wireless communication system, so that packets sent to D2D terminals with the same QoS requirements or packets sent by D2D terminals with the same QoS requirements can obtain the same QoS, thereby improving the quality of wireless communication.

Description

technical field [0001] The embodiments of the present invention relate to the field of wireless communication, and in particular, to a data transmission method and a terminal. Background technique [0002] In device-to-device (D2D) communication, a first terminal that is outside the coverage of the wireless communication system or within the coverage of the wireless communication system can establish a side chain with a second terminal that has accessed the wireless communication system. A sidelink connection (also known as a D2D connection) is used to communicate with the wireless network. Generally, the first terminal may be called a remote (remote) terminal or a D2D terminal, and the second terminal may be called a relay (relay) terminal. In the further evolved system of the LTE system and the fifth-generation wireless communication system, the air interface between the second terminal and the wireless access device transmits various information based on a radio bearer (...
