Embodiment Construction

[0020] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of this application.

[0021] Because the transmission power of the antenna of the electronic device cannot meet the requirements of SAR, a fallback mechanism is needed when the human body touches or is very close to the antenna of the electronic device to ensure that the human body is in a safe electromagnetic radiation power when it is close to the device. Down. At present, when SAR...

Abstract

The invention discloses an antenna working power adjusting method, device and equipment and a readable storage medium, and the method comprises the steps: responding to triggering SAR control, and recognizing a target detection channel for triggering SAR control; determining a target antenna correspondingly connected with the target detection channel and a working frequency band corresponding to the target antenna; and performing power back-off processing on the first working power of the working frequency band corresponding to the target antenna. By implementing the method and the device, power rollback processing can be only performed on the first working power of the target antenna which triggers SAR control, and rollback of the working power of other antennas on the electronic equipment is not triggered, so that for multiple antennas or antennas which do not trigger SAR, the working power of the antennas is not reduced, the uplink transmission speed of data is not influenced, and the transmission efficiency of the data is improved. The user experience can be improved.

Description

technical field [0001] The present application relates to the field of 5G technology, and in particular to a method, device, device and readable storage medium for adjusting the working power of an antenna. Background technique [0002] In the past, there was only one antenna on the Long Term Evolution (LTE) device of electronic equipment. As long as the user is close to the antenna or the antenna is touched by the user, the electromagnetic wave absorption ratio (Specific Absorption Rate, SAR) control will be triggered, and the frequency bands corresponding to the antenna will be controlled. The working power is backed up to ensure that the human body is under a safe electromagnetic radiation power when it is close to the electronic equipment. However, in 5G, there will be more antennas for electronic devices. If the previous SAR control logic is used, the working power corresponding to all frequency bands of all antennas will be backed off, which will cause unnecessary SAR ...
