Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently configuring communication parameters for vehicle-to-everything (V2X) communications, which are critical for ensuring quality of service (QoS) and optimizing data transmission in dynamic vehicular environments.
Innovation Solution
The proposed solution involves a method where user equipment (UE) determines and reports quality of service (QoS) parameters related to V2X communication. Based on this information, a configuration message is received and used to adjust communication settings, ensuring optimal data transmission and QoS in V2X systems.

1Productivity
If centralized predictive QoS configuration is implemented in V2X communications, then data transmission efficiency and reliability are improved, but system complexity and signaling overhead increase
Solution Approach 1:
The network side determines QoS configuration parameters in advance based on predictive models and vehicle context information (speed, location, trajectory) before actual data transmission occurs. This preliminary configuration is sent to the vehicle via RRC signaling, allowing the vehicle to pre-configure radio resources and transmission parameters, thereby improving transmission efficiency without real-time negotiation overhead.
Solution Approach 2:
The network side acts as an intermediary that collects vehicle context information, predicts QoS requirements, and determines optimal configuration parameters. This centralized predictive approach mediates between vehicle transmission needs and network resource constraints, reducing the complexity burden on individual vehicles while maintaining high transmission efficiency through network-coordinated resource allocation.
2Reliability
If real-time QoS parameter reporting and configuration adjustment are performed, then communication reliability is improved, but signaling overhead and transmission delay increase
Solution Approach 1:
QoS configuration parameters are determined and communicated to the vehicle in advance through RRC signaling before actual data transmission begins. The network side predicts future QoS requirements based on vehicle context (speed, location, trajectory) and pre-configures appropriate parameters, eliminating the need for real-time signaling adjustments and reducing transmission delay while maintaining reliability.
Solution Approach 2:
The system implements feedback mechanisms where vehicles report QoS experience and context information to the network, which then adjusts predictive models to improve future configuration accuracy. This feedback loop enhances communication reliability by continuously optimizing predictions based on actual transmission outcomes without requiring frequent real-time signaling exchanges.

AI summary
Certain aspects of the present disclosure are generally directed to techniques for selecting a configuration for communication using vehicle to everything (V2X) type communication protocol. Certain aspects provide a method for wireless communication by a user-equipment (UE). The method generally includes determining one or more parameters corresponding to quality of service (QOS) information for communication of data using a V2X communication protocol, reporting the one or more parameters by transmitting a first message, receiving a second message indicating configuration information corresponding to the communication of the data using the V2X communication protocol, and communication the data based on the configuration information.
