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.

If conservative A-MPR settings are applied based on per-carrier bandwidth assumptions, then network resource optimization is ensured, but network coverage is reduced

Engineering Contradiction:
Improvenetwork resource optimizationVSAvoidnetwork coverage
Core Design Contradiction:
ReliabilityVSArea of stationary object

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

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSDevice complexity

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.

Inventive Principle:
Principle #1Segmentation
