1. A method for interference detection in an unlicensed band, comprising:
- detecting, by a device, an interference signal of an unlicensed-band cell; and
transmitting data based on the detected interference signal;
wherein the interference signal is one of a total interference signal on the unlicensed band and an interference signal on the unlicensed band from another wireless communication system,wherein detecting, by the device, the interference signal of the unlicensed-band cell comprises obtaining center frequencies of one or more access points of other wireless communication systems according to configuration information, and detecting the interference signal within a part of a channel bandwidth of the unlicensed band cell based on the center frequencies of the one or more access points of the other wireless communication systems and a center frequency of the unlicensed band cell, andwherein the configuration information comprises information of the center frequencies of one or more access points of other wireless communication systems.

Abstract
The present invention provides a method and a device for interference detection on an unlicensed band. An LTE-U device works in an unlicensed-band cell, and the LTE-U device detects an interference signal of the unlicensed-band cell and processes data transmission. By adopting the method of the present invention, the LTE-U device works in the unlicensed band and may measure the interference signal from other wireless system, so as to avoid mutual interference between LTE-U and the other wireless communication system.
