V2X Protocol Entity Configuration for QoS Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in V2X environments, face challenges in efficiently managing Quality of Service (QoS) and optimizing access procedures due to limitations in protocol layer operations and data processing, which affect communication efficiency and security.
Innovation Solution
A method where user equipment (UE) in a V2X communication system receives protocol entity configuration information from the network entity to customize data processing at different protocol layers, avoiding concatenation, segmentation, and multiplexing as needed, to ensure optimized data transmission and secure communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If protocol entity configuration information is received and data processing is customized at different protocol layers, then communication efficiency and QoS management are improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic configuration of protocol entities (RLC, MAC, PHY layers) based on V2X application requirements. The system can selectively activate or deactivate specific protocol functions (concatenation, segmentation, multiplexing) depending on the service type and communication conditions, allowing the protocol stack to adapt its complexity to the actual needs rather than always operating at maximum capability.
Solution Approach 2:
Different protocol entities are configured with different operations tailored to specific V2X application types. For example, safety-critical applications may use one configuration while infotainment applications use another. This localized customization at each protocol layer enables optimized performance for specific functions without requiring the entire system to operate at high complexity.
2Adaptability or versatility
If concatenation and segmentation operations are performed on SDU, then data transmission flexibility is improved, but processing time and complexity increase
Solution Approach 1:
The patent applies concatenation and segmentation operations selectively rather than universally. The RLC layer performs these operations only when necessary based on the configured mode and application requirements. For time-critical V2X communications, the system may disable these operations to minimize processing time, while for other applications they remain enabled to provide transmission flexibility.
3Productivity
If multiplexing is applied at MAC layer, then resource utilization is improved, but QoS management difficulty increases
Solution Approach 1:
The patent segments different V2X application types and assigns them to different logical channels with specific QoS parameters. By dividing the traffic into distinct categories (safety, control, infotainment, etc.), each with its own multiplexing rules, the system can manage QoS more effectively while still utilizing resource pooling through multiplexing within each category.

AI summary
Disclosed is a communication method, wherein: protocol entity configuration information is received from a network entity; if an SDU the transmission of which has been requested by an application is received, a first protocol entity creates a first protocol PDU according to the protocol entity configuration information, without concatenation or segmentation of the SDU; a second protocol entity creates a second protocol PDU on the basis of the first protocol PDU; and a third protocol entity transmits the second protocol PDU to the network entity.
