摘要

A wireless communication method and device are disclosed. The method includes performing channel detection for a carrier in an unlicensed frequency band; and sending a preamble signal on the carrier from a first time-point, in response to the channel detection succeeding, the preamble signal being configured for indicating that the carrier has an ability to transmit a downlink signal.

說明書

In the several embodiments provided in present disclosure, it should be understood that, the disclosed system, device, and method may be implemented in other ways. For example, the device described above are merely illustrative. For example, the division of the units is only a logical function division, and there may be other divisions in actual implementation. For example, multiple units or components can be combined or can be integrated into another system, or some features can be ignored or not implemented. In addition, the displayed or discussed mutual coupling, direct coupling, or communication connection may be indirect coupling or communication connection through some interfaces, devices or units, and may be in electrical, mechanical, or other forms.

The units described as separate components may or may not be physically separated, and the components displayed as units may or may not be physical units. That is, they may be located at one position, or they may be distributed on multiple network units. Some or all of the units may be selected according to actual needs to achieve the objectives of the solutions of the embodiments.

In addition, the functional units in each embodiment of the present disclosure may be integrated into one processing unit, or each unit may exist alone physically, or two or more units may be integrated into one unit.
