Dynamic UE Uplink Power Limits for Extended-Range Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User equipment (UE) devices face challenges in communicating with base stations at extended ranges due to limitations in maximum uplink power, especially when channel conditions are adverse or when extra-terrestrial base stations are involved, leading to connectivity issues.
Innovation Solution
Dynamic adjustment of maximum uplink power limits based on the proximity of the UE to the user, allowing for increased transmission power when the UE is at a safe distance from the user, enabling communication with previously inaccessible base stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the maximum uplink power is increased to communicate with base stations at extended ranges, then the communication range and connectivity are improved, but the safety and interference avoidance are compromised
Solution Approach 1:
The patent applies dynamics by making the maximum uplink power limit adjustable rather than fixed. The system dynamically modifies the power limit based on real-time proximity detection to the user, allowing higher power when safe and lower power when proximity is detected, thus resolving the contradiction between communication range and safety
Solution Approach 2:
The patent changes the parameter of maximum uplink power limit from a static hard-set value to a dynamic value that varies based on proximity conditions. This parameter change enables the system to optimize both communication performance and safety by adapting the power level to the current operational context
2Object-affected harmful factors
If the maximum uplink power is hard-set to ensure safety and avoid interference, then the safety and interference avoidance are improved, but the communication range is limited
Solution Approach 1:
The system transitions from a static power limit to a dynamic one that responds to proximity conditions. When the UE is far from the user, the power limit is increased to extend communication range; when proximity is detected, the limit is reduced to ensure safety, thus resolving the contradiction
Solution Approach 2:
The maximum uplink power parameter is made variable based on proximity detection results. This allows the system to optimize the power level for each operational scenario, achieving both extended range when safe and safety protection when needed
3Use of energy by moving object
If the UE uses minimum necessary uplink power to optimize transmission, then the energy efficiency is improved, but the communication range is limited
Solution Approach 1:
The system dynamically adjusts the maximum uplink power parameter based on proximity conditions and communication needs. This allows the UE to use higher power when necessary for extended range communication and lower power when close to the user, optimizing both energy efficiency and connectivity

AI summary
Systems and methods are provided for managing maximum uplink transmission power of a UE. Based at least in part on a determination that the UE is greater than a predetermined threshold distance from a user, the maximum uplink power limit is increased from a default level to a higher level to facilitate extended-range communication in the uplink. With a greater maximum uplink power limit, the UE can communicate more effectively in degraded channel conditions or with base stations that are located at greater ranges from the UE, such as extra-terrestrial base stations including satellites.
