Problems solved by technology

[0004] However, since the signal transmission power of the mobile terminal directly affects the communication quality of the mobile terminal
Therefore, by reducing the signal transmission power of the mobile terminal to reduce the SAR of the mobile terminal, it is easy to cause the communication quality of the mobile terminal to be low and affect the core functions of the mobile terminal.
Therefore, this method of adjusting the SAR of the mobile terminal is less effective

Abstract

The invention discloses an electromagnetic wave absorption ratio adjusting method and device and a terminal, and belongs to the technical field of electronics. The electromagnetic wave absorption ratio adjustment method comprises the following steps: acquiring an actual electromagnetic wave absorption ratio of a terminal under the condition that signal transmission is carried out at the maximum transmission power in a target frequency band; under the condition that the actual electromagnetic wave absorption ratio is larger than an electromagnetic wave absorption ratio threshold value, a preset target antenna time slot proportion combination is obtained, and when all antennas of the terminal conduct signal emission according to the target antenna time slot proportion combination, the actual electromagnetic wave absorption ratio of the terminal is smaller than the electromagnetic wave absorption ratio threshold value; and adjusting the time slot ratio of each antenna of the terminal according to the target antenna time slot ratio combination.

Description

technical field [0001] This application belongs to the field of electronic technology, and specifically relates to a method, device and terminal for adjusting electromagnetic wave absorption ratio. Background technique [0002] With the development of mobile communication technology, the maximum transmission power of signal transmission of mobile terminals is getting higher and higher. However, during the communication process of the mobile terminal, electromagnetic radiation will inevitably be generated, which will affect the human body. Wherein, the greater the signal transmission power of the terminal, the stronger the intensity of electromagnetic radiation generated by the terminal. In order to evaluate the degree of influence of the electromagnetic radiation of the mobile terminal on the human body, the industry has introduced the index of Specific Absorption Rate, also known as Electromagnetic Wave Absorption Ratio (Specific Absorption Rate, SAR). SAR refers to the e...
