Wireless Communication Device Dummy Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bluetooth communication systems face challenges in extending the reception available period to ensure complete transmission of fragmented data without entering a reception unavailable state, leading to potential data loss and inefficiencies in power management.
Innovation Solution
A wireless communication system that includes a transmission terminal capable of temporarily storing segmented data and transmitting dummy data when the actual data is not available, thereby extending the reception available period until all data is transmitted, ensuring complete data transfer without entering the reception unavailable state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the reception terminal enters the reception unavailable state to reduce power consumption, then power consumption is reduced, but data transmission may be interrupted and reliability deteriorates
Solution Approach 1:
The transmission terminal transmits dummy data in advance during the reception available period to extend the period, ensuring that data transmission can be completed before the reception terminal enters the reception unavailable state, thus maintaining reliability while allowing power-saving mode operation
Solution Approach 2:
Dummy data acts as an intermediary element that occupies the communication channel and extends the reception available period, allowing the reception terminal to remain in the available state longer without requiring additional power, thereby resolving the contradiction between power consumption and transmission reliability
2Reliability
If the reception available period is extended to complete fragmented data transmission, then data transmission completeness is improved, but the reception terminal cannot enter power-saving mode and power consumption increases
Solution Approach 1:
All fragmented data packets including dummy data are transmitted in advance during the reception available period, so that by the time the reception terminal enters the reception unavailable state, all data transmission is already complete, allowing the terminal to enter power-saving mode without risking incomplete transmission
3Manufacturing precision
If the transmission terminal waits for actual data to be ready before transmission, then data transmission accuracy is maintained, but transmission time increases and productivity decreases
Solution Approach 1:
The transmission terminal prepares and transmits dummy data packets in advance during the reception available period, rather than waiting for actual data to be fully prepared, thereby utilizing the available time effectively and improving transmission throughput without compromising data integrity

AI summary
A wireless communication includes: a communication unit; a storage unit; a transmission buffer; and a controller. The communication unit wirelessly communicates with a reception terminal. The storage unit stores information relating to a timing at which the reception terminal changes from a first state to a second state. The first state is a state of being able to receive data and continues for a first period. The second state is a state of being unable to receive data and continues for a second period. The first period is extended by a fixed duration when the reception terminal in the first state receives data. The transmission buffer temporarily stores segmented data constituting transmission data to be transmitted to the reception terminal. The controller controls the communication unit to wirelessly transmit dummy data to the reception terminal by the timing if the segmented data is not stored in the storage unit.
