Uplink Power Control for Best Effort Throughput Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional best effort resource management in wireless communication systems cannot differentiate user experiences for delay-tolerant applications, limiting service providers' pricing strategies and failing to offer varying priority weights for users with similar RF conditions, resulting in uniform resource allocation and user experiences.
Innovation Solution
Implementing a method in mobile units and base stations to modify uplink transmission power based on a traffic-to-pilot power ratio attribute, which includes a priority weight and congestion information, allowing for differentiated best effort service levels by adjusting resource allocation dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional best effort resource management is used, then resources are fairly distributed among active users, but users with similar RF conditions receive the same resource allocation and user experience
Solution Approach 1:
The patent applies local quality by differentiating resource allocation based on individual user characteristics (priority weight, traffic-to-pilot power ratio) rather than treating all users uniformly. Each user receives customized resource management parameters that reflect their specific service requirements and RF conditions, enabling differentiated user experiences while maintaining manageable system complexity through standardized differentiation mechanisms.
2Adaptability or versatility
If a single resource allocation criterion is applied to all best effort applications, then resource management remains simple, but service providers cannot offer attractive pricing strategies
Solution Approach 1:
The patent implements dynamics by making resource allocation adaptive rather than static. The system dynamically adjusts resource allocation based on real-time user characteristics (priority weight, traffic-to-pilot power ratio) and network conditions, enabling service providers to offer flexible pricing strategies that respond to user needs while maintaining manageable complexity through automated adaptive mechanisms.
3Adaptability or versatility
If best effort resource management is used, then delay tolerant applications are served, but variations in data throughput, transmission delay and packet error rates cannot be differentiated
Solution Approach 1:
The patent applies parameter changes by differentiating service levels through modified allocation parameters (priority weight, traffic-to-pilot power ratio) rather than changing the fundamental best effort management approach. This allows the system to provide differentiated service levels for delay-tolerant applications while maintaining the reliability characteristics of best effort management, avoiding the need for strict service level guarantees.

AI summary
The present invention provides a method implemented in a mobile unit configured to communicate with at least one base station over an uplink. The method includes receiving, at the mobile unit and from the base station, a first attribute indicative of a traffic-to-pilot power ratio and a second attribute indicative of a resource provision limit. The first attribute is formed based on a priority weight associated with best effort communication with the mobile unit. The second attribute is formed based on a maximum throughput associated with best effort communication with the mobile unit. The method also includes modifying an uplink transmission power based upon the first attribute and information indicative of congestion at the base station.
