Abstract

The invention discloses a data transmission method, device and system of a cell for providing services by using an unlicensed spectrum, wherein the data transmission method comprises the following steps: when a service base station interacts data with the terminal by virtue of a downlink channel of the unlicensed spectrum, if the terminal detects that other service base stations need to interact data with other terminals by virtue of the downlink channel of the unlicensed spectrum, suspending data interaction with the service base stations, and sending channel occupied instructions to the other service base stations or the other terminals so that the other service base stations determine whether the downlink channel is occupied according to the channel occupied instructions. According to the technical scheme of the invention, the problem of transmission collision between LAA systems on the unlicensed spectrum and between the LAA systems and WIFI systems can be avoided.

Description

technical field [0001] The present invention relates to the technical field of data transmission, in particular, to a data transmission method for a cell using unlicensed spectrum to provide services, a data transmission device for a cell using unlicensed spectrum to provide services, and a method for using unlicensed spectrum to provide services The data transmission system of the served cell. Background technique [0002] Currently, with the rapid development of mobile services, the capacity of the existing wireless spectrum allocated to mobile services cannot meet the requirements. In the 3GPP Rel-13 stage, a mechanism called LAA (Licensed-Assisted Access) was introduced. In the LAA mechanism, the transmission of mobile communication can be carried on the unlicensed spectrum, such as the 5GHz frequency band. These unlicensed spectrums are mainly used by WiFi, Bluetooth, radar, medical and other systems at present. [0003] Due to the diversity and complexity of the sys...
