Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current LTE V2x side-link communication technologies, with fixed subcarrier intervals and subframe lengths, fail to meet the differentiated Quality of Service (QoS) requirements for advanced V2x services like vehicles platooning and remote driving, resulting in poor user experience due to inadequate communication quality and speed.
Innovation Solution
A method and device for acquiring a parameter set that supports various configurations for NR V2x side-link communications, allowing for dynamic or pre-configured parameter sets based on information types, carrier frequency bands, and time-frequency resource sets to ensure differentiated QoS requirements, including subcarrier intervals, cyclic prefix lengths, and time slot lengths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed subcarrier intervals and subframe lengths are used in LTE V2x side-link communication, then device complexity is reduced and ease of operation is improved, but adaptability to differentiated QoS requirements deteriorates
Solution Approach 1:
The patent segments the parameter configuration into multiple independent parameter sets, each optimized for specific service types (e.g., one set for basic safety applications, another for advanced driving services). This allows the system to select appropriate parameters based on service requirements without increasing overall system complexity, as each segment handles a specific function.
Solution Approach 2:
The patent introduces dynamic parameter selection mechanisms where parameter sets can be adjusted based on service type, channel conditions, and QoS requirements. This dynamic adaptation enables the system to transition from fixed LTE parameters to flexible NR parameters, improving adaptability while managing complexity through structured selection criteria.
2Reliability
If fixed parameter sets are used for all V2x services, then device complexity is reduced, but communication quality and speed for advanced services deteriorate
Solution Approach 1:
The patent applies local quality by configuring different parameter sets for different service locations in the parameter space. For example, basic safety services use one parameter configuration while advanced services like platooning use another. This ensures each service receives locally optimized parameters for its specific QoS requirements without requiring the entire system to be complex.
Solution Approach 2:
The patent utilizes parameter changes by transitioning from fixed LTE parameters to multiple NR parameter sets with varying subcarrier intervals, cyclic prefix lengths, and time slot configurations. This allows optimization of communication quality and speed for different services by selecting appropriate parameter combinations while managing complexity through standardized selection procedures.
3Productivity
If differentiated parameter sets are implemented for various V2x services, then adaptability to QoS requirements is improved, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple parameter sets before actual V2x communication begins. Each parameter set is pre-optimized for specific service types and QoS requirements. During operation, the system simply selects from these pre-prepared sets based on service type, avoiding real-time complex calculations and reducing operational complexity while maintaining high communication speed.
4Adaptability or versatility
If LTE fixed parameters are used for side-link communication, then ease of operation is improved, but ability to support advanced V2x services deteriorates
Solution Approach 1:
The patent achieves universality by designing a parameter set framework that can accommodate both basic LTE V2x services and advanced NR V2x services through a unified selection mechanism. The same system infrastructure supports multiple service types by selecting from different parameter sets, maintaining ease of operation through standardized procedures while enabling broad service support.
