Short-Range Communication Resource Coordination Against Link Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication scenarios with multiple communication domains, there is a high probability of resource overlap between communication links, leading to severe mutual interference, especially in medium or heavy load conditions, which deteriorates link quality and can prevent normal communication.
Innovation Solution
A communication method that involves a primary node indicating a non-overlapping time-frequency resource to a secondary node, allowing the secondary node to communicate using a subset of this resource, thereby establishing an inter-domain communication resource coordination mechanism to avoid resource conflicts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If frequency hopping communication is used for interference randomization, then low load communication can be maintained, but medium or high load communication quality deteriorates due to resource overlap
Solution Approach 1:
The patent segments the time-frequency resource into multiple non-overlapping resource pools, each assigned to different communication domains. This segmentation prevents resource overlap between domains while maintaining adequate resource allocation for each domain, resolving the contradiction between communication quality and load capacity.
Solution Approach 2:
The patent introduces domain identification as an additional dimension for resource allocation. By incorporating domain information into the resource allocation mechanism, the system can differentiate between communication domains and assign resources accordingly, preventing interference while supporting multiple domains simultaneously.
2Productivity
If multiple communication domains share the same time-frequency resources, then resource utilization is improved, but mutual interference between communication links increases
Solution Approach 1:
The patent divides the time-frequency resource into multiple non-overlapping resource pools, with each pool dedicated to a specific communication domain. This segmentation eliminates resource overlap and mutual interference while maintaining high resource utilization within each domain.
Solution Approach 2:
The patent applies local quality by assigning different resource characteristics to different communication domains. Each domain receives resources with properties optimized for its specific requirements, preventing interference while maximizing overall resource utilization.
3Adaptability or versatility
If communication domains dynamically increase or decrease, then system adaptability is improved, but resource coordination complexity increases
Solution Approach 1:
The patent establishes resource pools in advance before communication domains are formed. When domains dynamically appear or disappear, they simply allocate or release resources from the pre-established pools, avoiding complex real-time resource coordination and simplifying the management of dynamic changes.
Solution Approach 2:
The patent creates universal resource pools that can serve multiple communication domains. These resource pools are designed to be flexible and can be dynamically allocated to different domains as needed, supporting system adaptability without increasing coordination complexity.
