Dynamic Transmission Mode Selection for HSUPA Data Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current High-Speed Uplink Packet Access (HSUPA) technologies in WCDMA systems are limited by low data transmission efficiency due to the use of single stream mode, which restricts the ability to effectively utilize dual stream transmission modes, leading to reduced performance in data transmission.
Innovation Solution
A method and user equipment (UE) that dynamically select between single stream and dual stream transmission modes based on transmission mode determining conditions, such as maximum power availability and data block sizes, to optimize data transmission efficiency by combining the advantages of both modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If single stream mode is used for data transmission, then device complexity is reduced, but data transmission efficiency deteriorates
Solution Approach 1:
The patent implements dynamic transmission mode selection by introducing a determination module that selects between single stream and dual stream modes based on real-time transmission mode determining conditions. This dynamic adaptation allows the system to optimize data transmission efficiency while managing complexity through conditional logic rather than fixed configuration.
Solution Approach 2:
The patent changes the transmission mode parameter (single stream vs. dual stream) based on transmission mode determining conditions such as maximum power availability and data block sizes. By making this parameter variable rather than fixed, the system can adapt to different operational scenarios to improve overall transmission efficiency.
2Productivity
If dual stream mode is used for data transmission, then data transmission efficiency is improved, but device complexity increases
Solution Approach 1:
The system dynamically adjusts between single stream and dual stream modes based on transmission mode determining conditions, enabling dual stream operation only when beneficial. This dynamic approach captures the efficiency benefits of dual stream mode while avoiding the constant complexity overhead of always maintaining dual stream capability.
Solution Approach 2:
The patent applies dual stream mode selectively based on local conditions (transmission mode determining conditions such as power availability and data block size) rather than uniformly across all transmission scenarios. This localized application of dual stream mode optimizes efficiency where needed while reducing complexity where single stream suffices.
3Adaptability or versatility
If transmission mode selection is made dynamically, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent introduces a determination module that dynamically selects transmission modes based on transmission mode determining conditions. This dynamic selection mechanism improves adaptability to different transmission scenarios while managing complexity through a centralized decision-making structure rather than multiple independent control paths.
Solution Approach 2:
The determination module serves as a universal control element that handles all transmission mode selection decisions. By consolidating the adaptability function in a single multi-functional module, the system achieves high adaptability while avoiding the complexity multiplication that would result from distributed decision-making across multiple components.
