Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sidelink channel resource schemes in 5G wireless communication systems are inflexible and cannot be directly applied to the finer and more flexible resource configuration and scheduling methods, leading to inefficiencies in resource allocation and increased signaling overhead and complexity.
Innovation Solution
A method and apparatus for configuring sidelink channel resource units with flexible resource granularity in the time and frequency domain, allowing for improved resource allocation flexibility and reduced signaling overhead by defining and managing sidelink channel resources, where a sidelink channel resource unit comprises a specific number of resource units in the time and frequency domains, enabling efficient sidelink communications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current sidelink channel resource schemes are applied to 5G wireless communication systems, then resource allocation can be performed, but resource allocation flexibility is insufficient and cannot support finer resource granularity configuration
Solution Approach 1:
The patent segments the sidelink channel resources into configurable resource units with flexible granularity in both time and frequency domains. By dividing the resource pool into smaller, independently configurable units, the system achieves finer resource allocation control while maintaining manageable complexity through standardized unit definitions.
Solution Approach 2:
The patent introduces dynamic resource configuration where the number of resource units in time and frequency domains can be flexibly adjusted based on communication requirements. This dynamic configurability allows the system to adapt to varying traffic patterns and channel conditions without being constrained by fixed resource schemes.
2Adaptability or versatility
If flexible resource configuration with finer granularity is implemented, then resource allocation flexibility improves, but signaling overhead and processing complexity increase
Solution Approach 1:
The patent creates a universal resource unit structure that can represent multiple resource configurations through a standardized framework. By defining a general-purpose resource unit with configurable dimensions in time and frequency, the system reduces signaling overhead compared to defining separate configurations for each resource type.
Solution Approach 2:
The patent changes the parameters of resource units (number of time units, number of frequency units) to achieve different resource granularities. This parameter-based configuration allows flexible resource allocation while maintaining a consistent structural framework, reducing the need for extensive signaling to describe different resource types.
3Productivity
If finer resource granularity is used in time and frequency domains, then resource utilization efficiency improves, but processing complexity increases
Solution Approach 1:
The patent segments resources into standardized units that can be finely configured in time and frequency domains. This segmentation enables efficient resource utilization by allowing precise allocation matching traffic requirements, while the standardized unit structure keeps processing complexity manageable through uniform handling rules.
