Flexible Resource Allocation for URLLC Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems with centralized scheduling control, the flexibility of resource allocation is poor due to the fixed content of configuration information in Downlink Control Information (DCI), leading to inefficient resource management for Ultra-Reliable Low Latency Communication (URLLC) services.
Innovation Solution
A method and system for resource allocation that involves obtaining and notifying multiple types of configuration information, allowing for the selection and notification of specific resource block configurations tailored to individual User Equipment (UE) needs, including Physical Resource Blocks (PRBs), enabling flexible allocation based on device type, service type, and service level.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple types of configuration information are notified to enable flexible resource allocation, then adaptability improves, but device complexity increases
Solution Approach 1:
The configuration information is segmented into multiple types (first type, second type, third type, etc.), each containing specific resource block allocation parameters. This segmentation allows the system to notify different configuration types selectively based on UE requirements, achieving flexible resource allocation while managing complexity through structured organization of configuration data.
Solution Approach 2:
The system dynamically selects and notifies appropriate configuration information types based on real-time service requirements, UE capabilities, and resource availability. The access network device can adaptively choose which configuration types to notify, making the resource allocation system dynamic and flexible rather than static and rigid.
2Reliability
If configuration information is fixed according to protocol to reduce DCI data amount, then reliability improves, but adaptability deteriorates
Solution Approach 1:
The system performs preliminary notification of multiple configuration information types before actual resource allocation. By pre-notifying UEs with different configuration types (first type with PRB allocation, second type with resource block allocation, third type with mapping information, etc.), the system prepares the UE with multiple options in advance, enabling flexible selection during actual transmission while maintaining reliable control channel operation.
Solution Approach 2:
The system changes the parameters of configuration information by introducing multiple types with different parameter sets. Each configuration type contains different parameters (PRB allocation, resource block allocation, mapping information), allowing the system to adjust parameters according to specific service requirements while maintaining a structured approach that preserves control channel reliability.
