Problems solved by technology

[0002] In the LTE system, the frame structures corresponding to the FDD duplex mode and the TDD duplex mode are different from each other, and both are pre-defined, and cannot be flexibly changed according to communication requirements
In the prior art, the rigid design of the subframe frame structure leads to the complexity of LTE system communication and reduces the communication efficiency
For example, the existing LTE system cannot make the system design of the hybrid automatic repeat request (HARQ) timing, channel measurement or estimation method consistent under the two duplex modes; before communication, the terminal needs to detect the synchronization signal Determine the duplex mode of LTE communication, etc.

Abstract

The embodiment of the invention provides a data transmission method. The method comprises the following steps that: terminal equipment acquires configuration information, wherein the configuration information indicates that a sub-frame n is used for transmitting at least one of a downlink data channel, an uplink data channel, a downlink control channel, an uplink control channel, a downlink reference signal and an uplink reference signal; and the terminal equipment performs data transmission with network equipment on the sub-frame n according to the configuration information. Through the method, the design of a communication system can be unified on different flat bands; the communication complexity is lowered effectively; and the communication efficiency is increased.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a data transmission method, device and system. Background technique [0002] In the LTE system, the frame structures corresponding to the FDD duplex mode and the TDD duplex mode are different from each other, and both are pre-defined, and cannot be flexibly changed according to communication requirements. In the prior art, the rigid design of the frame structure of the subframe leads to the complexity of LTE system communication and reduces the communication efficiency. For example, the existing LTE system cannot make the system design of the hybrid automatic repeat request (HARQ) timing, channel measurement or estimation method consistent under the two duplex modes; before communication, the terminal needs to detect the synchronization signal Determine the duplex mode of LTE communication and so on.
