Transceiver EMR Regulation via Power and Antenna Control
Solution Overview
Problem
The increasing densification of wireless equipment and base stations leads to elevated electronic magnetic radiation (EMR) levels, posing health risks due to ionizing radiation, which existing technologies fail to adequately mitigate, particularly in close proximity to human bodies.
Innovation Solution
A method and system that measure EMR levels during transmission, detect when they exceed thresholds, and adjust transmission power and antenna direction to reduce EMR, using mechanisms such as muting packet transmission, adjusting applied power, and altering spatial antenna configurations based on measured EMR indexes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wireless equipment densification and base station deployment are increased to meet capacity demand, then network capacity and coverage are improved, but EMR exposure levels increase causing health risks
Solution Approach 1:
The system dynamically adjusts transmission parameters including muting packet transmission for allocated UL grants, adjusting applied power levels, and modifying spatial antenna directions based on real-time EMR measurements and feedback, transforming static transmission into adaptive dynamic control to reduce EMR while maintaining network capacity
Solution Approach 2:
The patent implements a feedback mechanism where EMR levels are measured and detected by the transceiver, and this information is used to regulate subsequent transmission decisions including power adjustment and packet muting, creating a closed-loop control system that continuously optimizes EMR reduction while maintaining communication quality
2Reliability
If transmission power is increased to improve communication quality and coverage, then signal strength is improved, but EMR radiation levels increase causing health concerns
Solution Approach 1:
The system changes transmission parameters including power levels and spatial directions based on EMR measurements, adjusting applied power corresponding to EMR indexes and modifying transmission characteristics to maintain communication reliability while reducing harmful radiation levels
Solution Approach 2:
The patent segments the transmission control into discrete actions including packet muting for specific UL grants, stepwise power adjustment based on quantized EMR indexes, and selective antenna element activation, allowing granular control over EMR reduction while maintaining necessary communication functions

AI summary
A system, transceiver, computer programming product, and method of regulating transmission of a packet from a transceiver are provided. The method includes measuring, by the transceiver, the electronic magnetic radiation (EMR) for an allocated uplink (UL) grant at a transmission time interval (TTI), detecting, by the transceiver, if the measured EMR exceeds an EMR threshold; and regulating, at the transceiver, a transmission of the packet to reduce the EMR.
