Terminal A-MPR Adjustment by DC Location for Network Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in optimizing network resources due to conservative A-MPR settings based on per-carrier bandwidth assumptions, leading to suboptimal scheduling and reduced network capacity and coverage.
Innovation Solution
Implementing a system that allows terminal devices to report adjusted A-MPR capabilities based on the actual direct current (DC) location within bandwidth parts, enabling the network to determine and apply more precise power reductions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conservative A-MPR settings are applied based on per-carrier bandwidth assumptions, then network resource optimization is ensured, but network capacity and coverage are reduced
Solution Approach 1:
The patent changes the parameter basis for A-MPR determination from conservative per-carrier bandwidth assumptions to actual DC location within bandwidth parts. This parameter change enables more accurate power reduction calculations, allowing the system to maintain reliable resource optimization while increasing network capacity by reducing unnecessary power reductions.
2Reliability
If conservative A-MPR settings are applied based on per-carrier bandwidth assumptions, then network resource optimization is ensured, but network coverage is reduced
Solution Approach 1:
By changing the determination parameter from conservative bandwidth assumptions to actual DC location, the system achieves more accurate A-MPR values. This accuracy improvement allows extended network coverage while maintaining resource optimization, as terminals apply appropriate power reductions only where necessary based on their actual DC location.
3Measurement precision
If accurate DC location reporting is implemented, then scheduling accuracy is improved, but device complexity increases
Solution Approach 1:
The patent segments the carrier bandwidth into multiple bandwidth parts, each with its own DC location. This segmentation allows accurate reporting of DC location within specific bandwidth parts rather than requiring complex full-carrier analysis, improving scheduling accuracy while managing terminal device complexity through focused, localized measurements.
