The invention discloses a method and a device for providing a reference clock signal for a wireless communication module. The method is applied to electronic equipment. The electronic equipment has a first processor and a second processor. The second processor includes a baseband circuit and a radio frequency circuit. The first processor first detects whether the baseband circuit is in a working state, and the first processor directly controls the radio frequency circuit to provide the reference clock signal for the wireless communication module when the baseband circuit is not in a working state. According to the method and the device, disclosed by the embodiment of the invention, for providing the reference clock signal for the wireless communication module, the first processor can directly send a control command to the radio frequency circuit of the second processor across the baseband circuit of the second processor to instruct the radio frequency circuit to perform corresponding operation. Therefore, the baseband circuit does not need to be started into a working state to forward the command of the first processor when in a nonworking state, thus reducing power consumption of the second processor.
