Service Group Resource Scheduling for Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing resource scheduling methods in wireless communications systems are inadequate for handling diverse service types, leading to reduced service processing efficiency when user equipment (UE) needs to handle multiple types of services with varying requirements.
Innovation Solution
Implementing a resource scheduling method that groups services into distinct service categories, allowing for tailored scheduling requests and allocations based on specific attributes such as latency, reliability, and data rate, thereby optimizing resource utilization and reducing signaling overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single resource scheduling mode is used for all services, then the scheduling process is simple, but it cannot meet the diverse requirements of different service types
Solution Approach 1:
The patent segments services into different service types (e.g., eMBB, uRLLC, mMTC) with distinct requirements, and creates separate scheduling request resources and processing paths for each service type. This allows the system to handle diverse service requirements while maintaining manageable complexity through structured classification.
Solution Approach 2:
The patent implements dynamic scheduling where the network device adapts its resource allocation and scheduling strategy based on the detected service type. Different service types trigger different scheduling behaviors, allowing the system to be flexible and adaptive to varying service requirements rather than using a fixed scheduling approach.
2Productivity
If separate scheduling is performed for each service type, then service processing efficiency is improved, but signaling overhead increases
Solution Approach 1:
The patent merges the scheduling request resources for different service types into a unified uplink resource structure. By combining service type indication with scheduling requests in a single uplink transmission, the system achieves separate processing for different services while minimizing redundant signaling overhead through resource consolidation.
3Measurement precision
If resource allocation is performed according to each UE request, then resource allocation accuracy is improved, but service processing efficiency deteriorates when multiple service types are present
Solution Approach 1:
The patent performs preliminary service type classification and identification before resource allocation. By detecting and categorizing the service type in advance of the actual resource allocation decision, the network device can prepare appropriate scheduling parameters and resources, improving both allocation accuracy for the specific service type and overall processing efficiency through proactive preparation.
