Embodiment 1

[0049] In this preferred embodiment, the first signal is an LTE signal, and the second signal is a WLAN. Therefore, a method and device for reducing the mutual interference between LTE and WLAN common equipment are provided to solve the problem of mutual interference between LTE and WLAN common equipment. .

[0050] The method for reducing mutual interference between LTE and WLAN co-equipment provided in this embodiment includes: the device for reducing mutual interference between LTE and WLAN co-equipment monitors the received signal quality of an LTE terminal working in a frequency band adjacent to the WLAN operating frequency band , wherein the signal quality is reflected by the combined value of SINR and RSRP; when the combined value of SINR and RSRP of the received LTE signal is lower than a certain threshold, an interference avoidance strategy is executed. Among them, RSRP refers to the received power of the reference signal obtained based on the reference signal measure...

Embodiment 2

[0062] Figure 4It is a system block diagram of a device for reducing mutual interference between LTE and WLAN co-equipment. The baseband data processing module is used to process the baseband digital signals of the two frequency bands, and realize information interaction and feedback. After receiving the signal sent by the baseband data processing module, the LTE radio frequency module amplifies the signal in the form of analog amplification and radiates it through the corresponding antenna, and at the same time receives the LTE signal from the base station; the WLAN radio frequency module also transmits the information through the WLAN antenna. Spread out and receive WLAN signals from other mobile terminals. While the LTE radio frequency module radiates energy, it feeds back the RSRP value of the received base station signal and the SINR value of the current environment to the monitoring and judgment module; at the same time, the WLAN radio frequency module transmits the fr...

Abstract

The invention discloses a method and device for reducing coexistence equipment mutual interference of networks of adjacent frequency bands. The method comprises the steps that the signal quality of a first signal is monitored; under the situation that the signal quality is lower than a preset quality threshold value, the working state of a second signal is adjusted so that equipment manual interference can be reduced, wherein the first signal and the second signal are the signals, with mutual interference, of the adjacent frequency bands. The method is simple and easy to implement, the influences caused by manual interference can be effectively reduced when the method and device are in use, and the problem that in the prior art, a simple and common method for eliminating coexistence equipment manual interference of networks of adjacent frequency bands does not exists is solved.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method and a device for reducing mutual interference of shared equipment between adjacent frequency band networks. Background technique [0002] In recent years, with the rapid development of mobile communication technology, the functions of terminal equipment have become more and more diversified and complex, especially with the third-generation mobile communication technology (3rd-generation, referred to as 3G) and the fourth-generation With the development of mobile communication technology (4rd-generation, 4G for short), the market demand for smart terminals is increasing day by day. Terminal devices such as smart phones usually require multiple wireless access technologies to be supported simultaneously in one device, such as Long Term Evolution (LTE for short) networks and Wireless Local Area Networks (WLAN for short), etc. . Since these access technologies are in ...
