Solution Overview
Problem
Existing wireless communication systems face challenges in ensuring stable communication of both security and non-security information, especially when traffic congestion or radio quality degradation occur, leading to insufficient communication resources.
Innovation Solution
A wireless communication system that dynamically adjusts the number of transmission repetitions for security and non-security information based on the quality of wireless communication, prioritizing security information and reducing non-security information transmission when communication quality degrades.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of transmission repetitions is increased for security information, then the reliability of security information communication is improved, but the communication resources are consumed more heavily
Solution Approach 1:
The patent applies different transmission repetition strategies to different types of information (security information vs. non-security information) based on their local importance. Security information receives higher repetition counts when communication quality degrades, while non-security information uses lower repetition counts, thereby allocating communication resources according to the local quality requirements of each information type.
Solution Approach 2:
The transmission repetition number is dynamically adjusted based on real-time communication quality assessment. When communication quality is good, fewer repetitions are used for both information types. When communication quality degrades, the system dynamically increases repetitions for security information while maintaining or reducing repetitions for non-security information, optimizing resource usage under varying conditions.
2Reliability
If the transmission rate is reduced to improve reception quality, then the communication stability is improved, but the communication efficiency is reduced
Solution Approach 1:
The system dynamically adjusts transmission parameters including transmission rate and repetition number based on real-time communication quality assessment. When communication quality is good, higher transmission rates are used for efficient data transfer. When communication quality degrades, the system reduces transmission rate and increases repetition numbers to ensure stable communication, particularly for security information.
Solution Approach 2:
The patent changes multiple transmission parameters simultaneously (transmission rate, repetition number, modulation scheme) based on communication quality conditions. This multi-parameter adjustment allows the system to optimize both communication efficiency and stability by coordinating multiple parameters rather than adjusting them independently.
3Reliability
If retransmission is performed multiple times to ensure data reception, then the communication reliability is improved, but the time consumption is increased
Solution Approach 1:
Different time budgets are allocated to different information types based on their local importance. Security information is allowed more time for multiple transmissions when communication quality degrades, while non-security information uses a stricter time budget with fewer permitted retransmissions, thereby managing overall time consumption according to information priority.
Solution Approach 2:
The maximum number of retransmissions is dynamically adjusted based on communication quality and information type. When communication quality is good, fewer retransmission attempts are allowed to reduce time consumption. When communication quality degrades, the system dynamically increases the maximum retransmission count for security information while maintaining limits for non-security information.

AI summary
A wireless communication system includes: a communication requirement management unit 301 configured to set, when wireless communication is performed between two parties at least one of which is a moving object, the number of times of repetition of transmission for each of security information and non-security information that is information other than the security information, according to quality of the wireless communication; and a wireless control unit 302 configured to control the wireless communication according to the set number of times of repetition. Accordingly, it is possible to provide a wireless communication system, a wireless communication method, and a communication control system that can perform wireless communication for both security information and non-security information and can ensure stable wireless communication for the security information.
