Solution Overview
Problem
Wireless communication devices with different reception functions face challenges in maintaining effective data communication over varying distances, particularly when the reception power is low or the detection of reference signals is difficult, leading to inefficient use of wireless resources and potential transmission interference.
Innovation Solution
A wireless communication device that dynamically adjusts the number of transmission times and transmission intervals based on the reception power of a reference signal and the transmission system, optimizing these parameters to ensure reliable communication while minimizing power consumption and interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of transmission times is increased to improve communication reliability, then the reliability of data communication is improved, but the power consumption increases and wireless resources are wasted
Solution Approach 1:
The patent applies dynamics by making the number of transmission times adjustable rather than fixed. The control unit dynamically determines the number of transmission times based on real-time measurement of reference signal reception power, allowing the system to adapt between low-power mode (fewer transmissions) and high-reliability mode (more transmissions) depending on channel conditions
Solution Approach 2:
The patent changes the parameter of transmission times based on reception power conditions. When reception power is strong, the system uses fewer transmission times to save energy. When reception power is weak, the system increases transmission times to maintain reliability, thus optimizing the balance between energy consumption and communication reliability
2Productivity
If the transmission interval is decreased to improve communication speed, then the productivity is improved, but transmission interference increases
Solution Approach 1:
The patent dynamically adjusts transmission intervals based on the determined number of transmission times and current channel conditions. The control unit sets appropriate intervals that prevent overlapping transmissions while maintaining efficient communication, adapting the interval length to the specific transmission scenario
Solution Approach 2:
The control unit determines the number of transmission times and sets transmission intervals in advance before actual data transmission begins. This preliminary configuration ensures that transmissions are scheduled to avoid interference while maintaining optimal communication speed, with the control unit managing timing before the transmission process starts
3Device complexity
If fixed transmission parameters are used to simplify device control, then the device complexity is reduced, but adaptability to different reception functions is worsened
Solution Approach 1:
The control unit autonomously determines the number of transmission times by measuring reference signal reception power and comparing it against thresholds. The system self-adjusts transmission parameters without external control, with the control unit automatically adapting to different reception functions based on measured channel conditions
Solution Approach 2:
The patent changes transmission parameters (number of transmission times, transmission intervals) based on measured reception power conditions. The control unit adjusts these parameters dynamically to match the specific reception capabilities of different devices, enabling adaptability while keeping the control logic relatively simple through threshold-based decision making

AI summary
Appropriate data communication is performed. A wireless communication device includes a communication unit and a control unit. The communication unit included in the wireless communication device receives a reference signal transmitted from a different device by using wireless communication. On the other hand, the control unit included in the wireless communication device determines, on the basis of reception power of the reference signal transmitted from the different device by using wireless communication, a number of times of transmission that data corresponding to a transmission target is repeatedly transmitted to the different device.
