Dynamic Downlink Control Information Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing wireless communication systems, the fixed resource allocation for downlink control information limits flexibility and efficiency, particularly in future 5G systems requiring wider bandwidths and multiple service types, leading to resource wastage and interference.
Innovation Solution
A method where a network device sends indication information to a terminal device to dynamically determine a resource area for downlink control information transmission, allowing flexible configuration of time-frequency resources, reducing unnecessary interference, and improving system performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed resource allocation is used for downlink control information, then system simplicity is maintained, but resource flexibility and system efficiency deteriorate
Solution Approach 1:
The patent applies dynamics by transitioning from fixed resource allocation to dynamic resource allocation for downlink control information. The resource area is no longer static but can be flexibly configured based on system conditions, service types, and bandwidth requirements. This allows the system to adapt resource allocation in real-time, improving flexibility and efficiency while managing complexity through standardized dynamic mechanisms.
Solution Approach 2:
The patent implements parameter changes by modifying the resource allocation parameters for downlink control information. Instead of fixed time-frequency resources, the system allows parameters such as resource area location, size, and configuration to change dynamically based on system needs, service requirements, and bandwidth availability, thereby resolving the contradiction between flexibility and complexity.
2Area of stationary object
If downlink control information spans entire system bandwidth, then coverage is maximized, but resource wastage increases
Solution Approach 1:
The patent applies local quality by allowing different parts of the system bandwidth to have different resource allocation characteristics for downlink control information. Instead of uniformly spanning the entire bandwidth, the resource area can be localized to specific frequency ranges or time-frequency regions where control information is actually needed, reducing resource wastage while maintaining necessary coverage through targeted allocation.
3Stability of the object's composition
If fixed time-frequency resources are allocated, then system stability is maintained, but interference management capability deteriorates
Solution Approach 1:
The patent resolves this contradiction by introducing dynamic resource allocation that can adapt to changing system conditions. The resource area for downlink control information can be adjusted in real-time to avoid interference with other signals or services, while maintaining system stability through standardized procedures and controlled change mechanisms that ensure reliable operation.
