Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is transmitted from multiple base stations using route diversity and site diversity technologies, then reliability of wireless communication is enhanced, but redundant transmission time increases
Solution Approach 1:
The destination apparatus sends acknowledgment frames back to transmitting apparatuses to indicate successful data reception. Each transmitting apparatus monitors these acknowledgments to determine whether retransmission is necessary, preventing redundant transmissions while maintaining reliability through multiple transmission paths
Solution Approach 2:
Each transmitting apparatus independently determines whether to retransmit data based on receiving acknowledgments for its own transmissions or acknowledgments indicating successful reception by the destination. This self-service mechanism eliminates the need for centralized coordination and reduces redundant transmissions
2Reliability
If acknowledgment frames are transmitted to multiple transmitting apparatuses, then reliable data delivery is ensured, but wireless communication channel usage increases
Solution Approach 1:
Each transmitting apparatus independently processes received acknowledgments to determine whether retransmission is needed. This allows the system to maintain reliable data delivery while minimizing channel usage by avoiding unnecessary acknowledgment transmissions and retransmissions
3Reliability
If retransmission is performed without checking acknowledgment status, then data delivery reliability is maintained, but power consumption increases due to unnecessary transmissions
Solution Approach 1:
Transmitting apparatuses monitor acknowledgment frames sent by the destination apparatus to determine whether data was successfully received. This feedback mechanism enables apparatuses to avoid unnecessary retransmissions and reduce power consumption while maintaining reliable data delivery
Solution Approach 2:
Each transmitting apparatus independently determines whether to retransmit based on receiving acknowledgments for its own transmissions or acknowledgments indicating successful reception by the destination. This self-service approach eliminates redundant retransmissions and reduces overall power consumption in the system

AI summary
According to one embodiment, an electronic apparatus includes a transmitter circuitry, a receiver circuitry, and a processing circuitry. The transmitter circuitry transmits a first data frame including first data to a destination apparatus. The receiver circuitry receives first acknowledgment information indicative of a reception state of the first data included in the first data frame. The receiver circuitry receives second acknowledgment information indicative of a reception state of the first data included in a second data frame. The second data frame is transmitted from another electronic apparatus to the destination apparatus. The processing circuitry determines whether the first data frame is retransmitted, based on at least one of the first and second acknowledgment information.
