Abstract

The present disclosure relates to a data transmission method, device, and system, and relates to the technical field of wireless communication. The method includes that: a base station acquires targettransmission direction indication information, wherein the target transmission direction indication information is used by a terminal to determine a transmission direction in which uplink data transmission and downlink data transmission are performed in a target mode, and the target mode is a mode in which the terminal performs uplink data transmission and downlink data transmission according todifferent carriers; the base station sends the target transmission direction indication information to the terminal; and the terminal determines the transmission direction in which uplink data transmission and downlink data transmission are performed in the target mode. The present disclosure solves the problem that the terminal cannot acquire the dynamic transmission direction indication information in the target mode, such as the FDD mode; and the terminal can acquire the dynamic transmission direction indication information in the target mode, thereby completing the data transmission in thetarget mode. The disclosure is used for data transmission.

Description

technical field [0001] The present disclosure relates to the technical field of wireless communication, and in particular to a data transmission method, device and system. Background technique [0002] In the field of wireless communication, there are two modes of duplex communication: time division duplex (Time Division Duplexing, TDD) mode and frequency division duplex (Frequency Division Duplexing, FDD) mode. In FDD mode, uplink data transmission and downlink data transmission are performed on different carriers. [0003] In a traditional FDD system, only downlink data can be transmitted on the downlink carrier, and only uplink data can be transmitted on the uplink carrier. The continuous emergence of emerging Internet applications such as a new generation of virtual reality (or augmented reality) and vehicle-to-vehicle communication has put forward higher requirements for wireless communication technology, which requires terminals to support more types of services. If y...
