Terminal Device Beam Switching for Radiation Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication devices face challenges in reducing electromagnetic radiation intensity to ensure safety when in close proximity to the human body, as current methods do not effectively manage radiation levels to avoid exceeding safety standards like SAR and MPE limits.
Innovation Solution
A communication method where a terminal device sends a notification message to a network device when radiation intensity exceeds a preset limit, allowing the network device to respond with information about a second beam or antenna panel that can be used to reduce radiation intensity, enabling the terminal device to switch and communicate using this alternative configuration, thereby reducing radiation exposure.

1Productivity
If the terminal device uses a first beam for communication, then the uplink transmission speed and coverage are maintained, but the radiation intensity directed at the human body exceeds safety standards
Solution Approach 1:
The terminal device changes the beam parameter (switching from first beam to second beam) to alter the radiation characteristics. This parameter change allows maintaining communication performance while reducing radiation intensity directed at the human body to comply with safety standards.
Solution Approach 2:
The system dynamically switches between different beam configurations based on radiation intensity conditions. When the first beam causes excessive radiation, the terminal device transitions to using the second beam, creating a dynamic adaptation mechanism that balances communication performance with safety requirements.
2Object-affected harmful factors
If the terminal device switches to a second beam to reduce radiation intensity, then compliance with safety standards is achieved, but the communication configuration must be changed
Solution Approach 1:
The terminal device autonomously monitors its own radiation intensity and automatically switches beams when safety thresholds are exceeded. This self-service mechanism eliminates the need for external control complexity, as the device manages its own configuration changes based on real-time radiation conditions.
Solution Approach 2:
The terminal device uses feedback from radiation intensity measurements to trigger beam switching. The notification message sent to the network device carries radiation intensity information, creating a feedback loop that automatically initiates configuration changes when safety criteria are met.
3Object-affected harmful factors
If the terminal device sends a notification message about radiation intensity, then the network device can provide alternative beam information, but additional signaling overhead is introduced
Solution Approach 1:
The terminal device sends a notification message in advance when radiation intensity reaches threshold levels, allowing the network device to proactively provide alternative beam configuration information. This preliminary action prevents radiation compliance issues before they occur, reducing the need for corrective signaling later.

AI summary
This application provides a communication method and a communications device, to reduce or avoid an intensity of radiation directed to a human body. The method includes: A terminal device sends a notification message, where the notification message is used to notify a network device of information about a radiation intensity of the terminal device when the terminal device uses a first beam and/or a first antenna panel. The terminal device sends data by using a second beam and/or a second antenna panel, where a radiation intensity of the terminal device when the terminal device sends data by using the second beam and/or the second antenna panel is less than the radiation intensity of the terminal device when the terminal device uses the first beam and/or the first antenna panel.
