Blockchain-Aware Mobile Vehicle Communication to Reduce Forking Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of blockchain technology in vehicle networks faces challenges, particularly in 3GPP 5G, B5G, or 6G systems, due to increased forking events caused by varying transmission delays and channel qualities, which lead to increased latency and computational inefficiencies.
Innovation Solution
A blockchain-aware resource request and allocation mechanism is implemented, where block information is transmitted along with a scheduling request from a VUE miner to an infrastructure node, allowing the infrastructure node to determine resource allocation based on the indication and information from the blockchain network, thereby reducing the occurrence of forking events.

Engineering Contradiction Analysis
1Reliability
If blockchain technology is integrated into vehicle networks with decentralized trust architecture, then security and adaptability are improved, but transmission delays and channel quality variations cause increased forking events and latency
Solution Approach 1:
The patent applies preliminary action by having the VUE miner transmit block information along with the scheduling request before actual resource allocation occurs. This allows the infrastructure node to prepare resource allocation in advance based on the blockchain network state, reducing transmission delays and forking events by having resources ready before they are needed.
Solution Approach 2:
The patent implements feedback mechanisms where the infrastructure node receives block information from the blockchain network, processes it to determine appropriate resource allocation, and sends scheduling responses back to the VUE miner. This closed-loop feedback system allows the network to adapt to changing conditions and reduce forking events by making informed resource allocation decisions based on real-time blockchain state.
2Device complexity
If traditional resource allocation methods are used in blockchain vehicle networks, then device complexity is reduced, but forking events increase due to lack of blockchain awareness
Solution Approach 1:
The patent applies universality by designing a resource allocation mechanism that serves multiple functions: it handles traditional scheduling requests while simultaneously incorporating blockchain-aware resource determination. The infrastructure node processes both conventional communication needs and blockchain-specific resource allocation in a unified framework, reducing forking events without significantly increasing complexity.
Solution Approach 2:
The patent introduces an intermediary mechanism where the infrastructure node acts as a mediator between the VUE miner and the blockchain network. It receives block information, processes it to determine resource allocation, and translates blockchain requirements into actionable scheduling decisions, thereby reducing forking events while maintaining manageable system complexity.
3Productivity
If block information is transmitted with scheduling requests, then resource allocation efficiency is improved, but communication overhead increases
Solution Approach 1:
The patent applies merging by combining block information transmission with the existing scheduling request protocol. Instead of separate communications, the block information is integrated into the scheduling request message structure, allowing efficient resource allocation while minimizing additional communication overhead by utilizing existing communication channels.

AI summary
The present application is related to a method and apparatus for blockchain-aware mobile vehicle communication for 3GPP (3rd Generation Partnership Project). A method for wireless communications performed by a user equipment (UE), e.g., a vehicle UE (VUE), includes: receiving configuration information of a blockchain application; transmitting information associated with a candidate block of the blockchain application; and receiving a response related to the candidate block.
