Vehicle Base Station Wireless Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication within motor vehicles suffers from signal penetration loss and excessive interference, particularly in crowded roadways, leading to poor user experience and network quality.
Innovation Solution
Equipping vehicles with an access transceiver for communication within the cabin and a backhaul transceiver for external communication, allowing the vehicle to act as a base station, which establishes connectivity between devices and the wireless network, and dynamically allocates resources based on vehicle position, speed, trajectory, and environmental parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If smartphones and wireless devices are used from within the passenger cabin, then users can access wireless communication, but signal penetration loss through walls and ceiling reduces communication quality
Solution Approach 1:
The vehicle acts as an intermediary base station between external wireless networks and devices inside the cabin. The vehicle's transceivers receive signals from external networks and retransmit them internally, mediating the connection to avoid direct penetration through cabin walls and ceiling, thereby resolving the signal loss problem.
Solution Approach 2:
The wireless communication system is segmented into two distinct interfaces: an access interface for internal cabin communication and a backhaul interface for external network communication. This segmentation allows optimized resource allocation and signal handling for each interface, improving overall communication reliability while managing penetration loss effects.
2Reliability
If many mobile devices operate from within motor vehicles on crowded roadways, then users can maintain connectivity, but high-power transmissions create excessive interference to other signals
Solution Approach 1:
The base station implements feedback mechanisms to monitor signal conditions, interference levels, and device locations within the vehicle. Based on this feedback, the system dynamically adjusts transmission parameters such as power levels, resource allocation, and modulation schemes to maintain connectivity while minimizing interference to external signals.
Solution Approach 2:
The system dynamically allocates wireless resources including time-frequency slots, power levels, and spatial beams based on real-time conditions. This dynamic adaptation allows the system to optimize connectivity for multiple devices while adjusting transmission characteristics to reduce interference with external signals in crowded roadway environments.
3Reliability
If the vehicle acts as a base station with access and backhaul transceivers, then connectivity between devices and wireless network is established, but resource allocation complexity increases
Solution Approach 1:
The vehicle's transceiver system is designed with multi-functionality to handle both access interface communications with cabin devices and backhaul interface communications with external networks. This universal design consolidates multiple functions into integrated hardware and software modules, managing the complexity of dual-interface resource allocation while establishing reliable connectivity.
