Problems solved by technology

[0003] Due to the existence of multiple transmitting antennas, in the actual production process, it is difficult to ensure that the maximum transmitting power of multiple antennas is consistent, and the antenna with a large maximum transmitting power may have the problem that Radiated Spurious Emission (RSE) does not meet the RSE standard certification requirements. In response to this situation, before the mobile device leaves the factory, once it is found that there is a problem that the RSE does not meet the RSE standard certification requirements, the current practice is to forcibly reduce the maximum transmission power of multiple antennas at the same time according to the unified adjustment, and use it after leaving the factory. During the process, the mobile device will communicate with the maximum transmit power reduced according to the unified adjustment to ensure that the radiation spurious meets the RSE standard certification requirements. In this way, the antenna with a lower maximum transmit power will have a maximum transmit power The power is reduced to a lower level, which may cause the user to be unable to use the mobile device normally, and the user experience is poor

[0082] Such as Figure 4 As shown, the method of this embodiment can be implemented during the use of the mobile device, and the method of this embodiment includes:

[0083] Step 401, selecting the antenna with the best performance from the multiple antennas of the mobile device as the transmitting antenna;

[0084] Before step 401 is executed, the received signal strength of multiple antennas can be detected under the same conditions. The transmission and reception of the antennas are directly related, and it can be judged which antenna has the best performance by comparing the received signal strengths of multiple antennas. Generally speaking, the antenna with better performance is the antenna with the best received signal strength among multiple antennas. After the transmitting antenna is selected from multiple antennas, the transmitting path can be switched to the currently selected transmitting antenna through the antenna switching switch.

[0085] Step 402: Invoke the ...

Abstract

The embodiments of the invention disclose a method for controlling radiated spurious emission standard exceeding, a device for controlling radiated spurious emission standard exceeding and a mobile device. The method includes the following steps that: radiated spurious emissions generated by each antenna in a plurality of antennas is measured respectively under maximum transmitting power when the plurality of antennas are adopted as the transmitting antenna of the mobile device; when an antenna of which the radiated spurious emissions exceed standards exists in the plurality of antennas, the maximum transmitting power calibration value of the antenna of which the radiated spurious emissions exceed standards can be obtained through calculation according to the difference value of the measurement value of the radiated spurious emissions of the antenna adopted as the transmitting antenna and a standard value; and the maximum transmitting power calibration value of the antenna of which the radiated spurious emissions exceed standards is stored in the mobile device. With the method and device provide by the embodiments of the invention adopted, the radiated spurious emissions of the antenna can satisfy the requirements of RSE (radiated spurious emission) standards, and user experience can be enhanced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular to a method, device and mobile device for controlling excess radiation spurious. Background technique [0002] At present, mobile devices mostly use the frame or back cover gap as the radiator of the antenna, and the transmitting antenna is designed at the bottom of the mobile device, which may cause the risk of the antenna being held to death during use. The improvement solution is to add one or more For the transmitting antenna, a part of the transmitting antenna is designed on the top of the mobile device, and another part of the transmitting antenna is designed on the bottom of the mobile device. [0003] Due to the existence of multiple transmitting antennas, in the actual production process, it is difficult to ensure that the maximum transmitting power of multiple antennas is consistent, and the antenna with a large maximum transmitting pow...
