RADIO FREQUENCY POWER CALIBRATION CONTROL METHOD AND APPARATUS FOR WIRELESS DEVICE, AND TERMINAL DEVICE

WIPO Patent Application WO/2024/041378

A1

Disclosed in the present invention are a radio frequency power calibration control method and apparatus for a wireless device, and a terminal device. A first error vector amplitude of a target wireless device is obtained according to screened first power control data, thus the requirements on product qualities of most wireless devices can be satisfied, thereby avoid using invalid power control data for radio frequency tests, and improving the calibration efficiency of wireless devices. Meanwhile, by comparing the relationship between the first error vector amplitude and a preset amplitude value, whether a first error vector satisfies the amplitude index is determined; if yes, power calibration is completed, and if not, numerical adjustment is carried out on the first power control data by means of a subtraction algorithm. For products which cannot satisfy the requirement of the amplitude index of the error vector under the power corresponding to the first power control data, the power control data is adjusted by means of the subtraction algorithm, thereby ensuring that wireless devices can satisfy the requirement of the error vector amplitude, and improving the wireless coverage performance of wireless devices.
