A-MPR Adjustment by DC Location for UE Power Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks struggle with inefficient utilization of network resources due to conservative and pessimistic scheduling caused by unknown or inaccurate additional maximum power reduction (A-MPR) values, leading to reduced network capacity and coverage, as they lack precise information on each UE's actual A-MPR capability.
Innovation Solution
Implementing a system where terminal devices report their adjusted A-MPR capabilities and direct current (DC) locations to network elements, allowing the network to determine and apply adjusted A-MPR based on pre-defined rules, optimizing resource allocation and scheduling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conservative and pessimistic scheduling is applied due to unknown A-MPR values, then network reliability is maintained, but network capacity and coverage are reduced
Solution Approach 1:
The patent implements feedback mechanisms where terminal devices report their actual A-MPR capabilities to the network. The network element receives capability information indicating the terminal's adjusted A-MPR capability and uses this feedback to determine optimized A-MPR values, replacing conservative estimates with actual measured capabilities, thereby improving network capacity while maintaining reliability
Solution Approach 2:
The patent applies preliminary action by having terminal devices report their A-MPR capabilities in advance before actual resource allocation occurs. The network element obtains capability information and determines adjusted A-MPR values proactively, allowing for optimized scheduling decisions to be made beforehand rather than relying on pessimistic assumptions during real-time allocation
2Device complexity
If conservative A-MPR values are used due to lack of precise terminal capability information, then interference control is simplified, but network coverage is reduced
Solution Approach 1:
The patent uses feedback to obtain precise terminal A-MPR capability information from terminal devices. The network element receives capability information and determines adjusted A-MPR values based on actual terminal characteristics rather than conservative defaults, enabling extended network coverage while maintaining interference control through accurate, terminal-specific parameter optimization
Solution Approach 2:
The patent applies local quality by determining A-MPR values specific to each terminal device's actual capabilities rather than applying uniform conservative values across all terminals. The network element customizes A-MPR adjustments for individual terminals based on their reported capabilities, allowing each terminal to operate at its optimal power level for coverage extension while maintaining overall interference control
3Device complexity
If uniform A-MPR adjustments are applied to all terminals, then resource allocation is simplified, but network throughput is reduced
Solution Approach 1:
The patent implements local quality by determining customized A-MPR values for each terminal device based on their individual capability information. The network element receives capability information from each terminal and determines adjusted A-MPR values specific to that terminal's characteristics, enabling optimized resource allocation that maximizes network throughput while maintaining manageable complexity through automated per-terminal optimization
Solution Approach 2:
The patent applies parameter changes by dynamically adjusting A-MPR values based on terminal-specific capability parameters. The network element modifies the A-MPR parameter for each terminal according to its reported adjusted A-MPR capability, allowing resource allocation to be optimized for each terminal's actual performance characteristics rather than applying uniform adjustments, thereby increasing overall network throughput
