Abstract

Embodiments of the present invention provide a method and device for data transmission. The method includes: the first device determines a set of candidate time points; the first device determines target candidate time points from the set of candidate time points; Send data in the channel at the selected time. In the above technical solution, the time when the first device sends data is determined according to the candidate time in the set of candidate time. In this case, the corresponding second device receiving the data may also determine the time at which the data can be received according to the candidate time in the set of candidate time. That is to say, the second device may detect the channel only at the time specified by the system when data can be sent, and does not need to continuously detect the channel at other times. Therefore, the above technical solution can reduce the power consumed by the second device when detecting a channel.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and more specifically, to a data transmission method and device. Background technique [0002] Devices in the Long Term Evolution Licensed Spectrum Assisted Access (English: Licensed-Assisted Access Using LongTerm Evolution, abbreviation: "LAA-LTE") system use the channel through the principle of listening before speaking (English: Listen BeforeTalk, abbreviation "LBT") resource. The working mode of the LBT is divided into a load-based (English: Load Based Equipment, "LBE" for short) working mode and a frame-based (Frame Based Equipment, "FBE" for short) working mode. [0003] When performing data transmission in the LAA-LTE system, the receiving end device needs to continuously detect the channel to obtain data, which causes relatively large power consumption of the receiving end device. Contents of the invention [0004] The embodiments of the present inventi...
