Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing uplink transmission resource allocation schemes in LTE and 5G systems face challenges such as high implementation difficulty, time consumption, signaling overhead, and resource collisions leading to low transmission efficiency and failure due to multiple terminal devices selecting the same resources.
Innovation Solution
A method where terminal devices determine uplink transmission resources based on their channel state information and correspondence relationships broadcast by the network device, reducing the need for multiple interactions and enabling accurate demodulation even when multiple devices use the same resources using the principle of serial interference cancellation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a centralized resource allocation mode is used, then resource scheduling control is strong, but system flexibility and user autonomy are reduced
Solution Approach 1:
The patent divides resource allocation into two segments: strategic resource allocation decisions made by the user (e.g., budget settings, priority levels) and tactical execution made by the system's scheduling algorithms. This segmentation allows users to maintain control over key parameters while the system autonomously optimizes resource distribution, resolving the contradiction between centralized control and system flexibility.
2Ease of operation
If manual resource allocation is used, then user control is high, but allocation efficiency and timeliness are reduced
Solution Approach 1:
The system performs preliminary actions by pre-configuring resource allocation policies, budgets, and constraints based on user preferences. When resource allocation events occur, the system automatically executes pre-planned allocation strategies without requiring real-time user intervention, thereby maintaining user control while significantly improving allocation efficiency and timeliness.
3Productivity
If automated resource allocation is used, then allocation efficiency is improved, but transparency and user understanding are reduced
Solution Approach 1:
The patent implements comprehensive feedback mechanisms that provide users with real-time or near-real-time information about resource allocation decisions, including why specific allocations were made, how budget constraints were applied, and what alternatives were considered. This feedback loop maintains allocation efficiency through automation while ensuring users understand and can trace the reasoning behind automated decisions.
4Stability of the object's composition
If resource allocation follows fixed rules, then system stability is maintained, but adaptability to changing conditions is reduced
Solution Approach 1:
The system employs dynamic resource allocation rules that can adapt to changing conditions while maintaining overall stability. Allocation parameters such as budgets, priorities, and constraints are designed to be adjustable within defined ranges, allowing the system to respond to changing user needs and environmental conditions while preventing chaotic or unpredictable behavior through boundary conditions and validation rules.
