Embodiment Construction

[0025] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0026] In the ensuing description, suffixes such as 'module', 'component' or 'unit' used to represent elements are used only to facilitate the description of the present invention, and have no specific meaning per se. Thus, "module", "component" or "unit" may be used interchangeably.

[0027] figure 1 It is a schematic diagram of setting the SAR threshold and power threshold when two frequency bands are concurrently provided by related technologies, such as figure 1 As shown, the related art sets the power threshold when two frequency bands are concurrent, and the technical means has the disadvantage that the maximum transmit power threshold of each concurrent frequency band is determined. In actual use, each frequency band will not always transmit at the maximum power.

[0028] Take the practical application...

Abstract

The embodiment of the invention discloses an electromagnetic wave absorption ratio SAR control method and device, equipment and a storage medium, and the method comprises the steps: determining the actual working SAR value of a current frequency band according to the working state of the current frequency band, and the working state comprises a power control value, a transmitting antenna, a transmitting time slot ratio and a transmitting bandwidth ratio; calculating the margin value of the current SAR value according to the actual working SAR value of the current frequency band and a preset SAR target value; and when it is detected that a newly-added frequency band is added, taking the margin value of the current SAR value as an SAR value threshold of the newly-added frequency band so as to realize control of the SAR values of the current frequency band and the newly-added frequency band under a concurrent condition.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a control method, device, device and storage medium for electromagnetic wave absorption ratio SAR. Background technique [0002] SAR (Specific Absorpt ion Rate, electromagnetic absorption ratio) is the index requirement of wireless terminal products in terms of electromagnetic radiation. The threshold for determining SAR is to ensure that the ratio of the electromagnetic wave energy emitted by the terminal to be absorbed by the user's body tissue is less than the target value. With the emergence of 5G terminals, the state of multi-mode, multi-frequency and multi-channel concurrency has become the norm. For example: concurrency of 4G and 5G under NSA, 5G uplink CA, 5G uplink MIMO, transmit diversity, transmit antenna switching, and the concurrency of wifi and 2, 3, 4, and 5G frequency bands when the terminal is used as a wifi hotspot (to simplify the descript...
