Synchronized Resource Signaling for Scalable Wireless Node Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in scalability due to varying time-frequency resource configurations and system information formats across different types of vehicles and communication domains, necessitating complex blind detection processes for synchronization and resource allocation.
Innovation Solution
A method involving the transmission of synchronized signals and messages on specific time-frequency resources, including a first message for synchronization, a second message for system information, and optional messages for access requests and scheduling, which directly provide resource and format information, reducing blind detection and improving scalability.

Engineering Contradiction Analysis
1Adaptability or versatility
If different types of vehicles and communication domains use different time-frequency resource configurations and system information formats, then communication services and features can be diversified, but system complexity increases and scalability deteriorates
Solution Approach 1:
The patent applies universality by designing a unified system information structure where a single set of system information blocks (SIBs) can serve multiple vehicle types and communication domains. The primary node configures time-frequency resources and system information in a standardized format that secondary nodes can universally interpret, eliminating the need for separate configurations for different vehicle types while maintaining diverse service capabilities.
Solution Approach 2:
The patent utilizes parameter changes by introducing configurable parameters within the unified system information framework. Different vehicle types and communication domains can be supported by varying specific parameters (such as time-frequency resource allocation patterns, cyclic prefix lengths, and message formats) within the standardized SIB structure, allowing diversification without increasing overall system complexity.
2Adaptability or versatility
If external nodes perform blind detection to synchronize with communication domains and obtain system information, then nodes can join different types of communication domains, but detection complexity and time consumption increase
Solution Approach 1:
The patent applies preliminary action by having primary nodes pre-configure and broadcast system information through system information blocks before external nodes attempt to join. The SIBs contain pre-defined time-frequency resource configurations, synchronization parameters, and supported features that external nodes can directly acquire without performing complex blind detection, thereby reducing detection complexity while maintaining the ability to join different communication domains.
3Adaptability or versatility
If primary nodes manage time-frequency resources and schedule communication links for diverse communication domains, then resource allocation flexibility improves, but scheduling complexity and resource management overhead increase
Solution Approach 1:
The patent applies segmentation by dividing system information into multiple structured blocks (SIB1, SIB2, etc.), each containing specific resource configuration parameters. Primary nodes can independently configure and update individual SIBs for different communication domains without reconfiguring the entire system information structure. This segmented approach enables flexible resource allocation across diverse domains while reducing overall scheduling complexity through modular information management.
