UE High Power Mode SAR Compliance via Dynamic Resource Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication technologies, particularly with 5G NR and LTE, User Equipment (UE) operating in high power modes can exceed Specific Absorption Rate (SAR) measurement standards due to inappropriate uplink/downlink resource ratios, leading to potential health risks and reduced transmission capacity.
Innovation Solution
A method where the UE dynamically adjusts its resource configuration based on SAR capability information, allowing the base station to optimize the uplink proportion to prevent SAR exceedance while enhancing transmission capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the UE operates in high power mode to increase uplink coverage, then the uplink transmission capacity is improved, but the wireless signal radiation may exceed the preset SAR measurement standard
Solution Approach 1:
The patent applies dynamics by making the uplink proportion adjustable rather than fixed. The network can dynamically configure the uplink proportion based on the UE's SAR capability information, allowing the system to adapt between high transmission capacity and SAR compliance in real-time
Solution Approach 2:
The patent changes the parameter of uplink proportion from a fixed value to a configurable parameter. By adjusting the uplink proportion parameter based on SAR capability information, the system can optimize transmission capacity while maintaining SAR compliance
2Productivity
If the uplink proportion is increased to improve transmission capacity, then the productivity is improved, but the SAR measurement standard may be exceeded
Solution Approach 1:
The patent implements feedback by having the UE report its SAR capability information to the network. The network then uses this feedback information to configure appropriate uplink proportions, creating a closed-loop system that ensures both high transmission capacity and SAR compliance
Solution Approach 2:
The patent applies preliminary action by having the UE report its SAR capability information before the network configures the uplink proportion. This allows the network to pre-determine safe uplink proportions based on the UE's SAR characteristics, preventing SAR exceedance before it occurs

AI summary
The present disclosure provides methods and apparatuses for transmitting information, base stations, and UE. The method includes: determining whether the UE supports a preset adjustment function, where the preset adjustment function instructs a base station to dynamically adjust resource configuration information for the HPUE based on SAR capability information of the UE; if the UE supports the preset adjustment function, determining target resource configuration information corresponding to a preset high power mode; and transmitting information according to the target resource configuration information in the preset high power mode. Using the method of transmitting information provided by the present disclosure, it is possible to realize that no SAR exceedance will occur when the UE operates in the preset high power mode, to ensure that the amount of radiation generated by the UE in the preset high power mode will not affect health of a terminal user, and to improve uplink information transmission capability of the UE in the preset high power mode.
