Dynamic Reception Duration Control for Wireless Data Error Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, long intermittent reception intervals lead to prolonged communication times due to increased waiting times when data errors occur, caused by factors like signal collisions or degradation of wireless radio waves.
Innovation Solution
A wireless communication system with a second device that performs intermittent reception by repeating a specific reception duration at a constant period, equipped with a data error detector to extend the reception duration if errors are detected, and a packet data number confirmation component to dynamically calculate the necessary extension time, ensuring the reception duration is set to the minimum.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If intermittent reception is used to reduce power consumption, then power consumption is reduced, but communication time increases due to waiting periods
Solution Approach 1:
The reception duration is made dynamic rather than fixed. The system automatically extends the reception duration when data errors are detected, and maintains minimum duration when no errors occur. This dynamic adjustment resolves the contradiction by adapting the reception pattern to actual communication conditions, reducing unnecessary waiting time while maintaining power-saving benefits.
Solution Approach 2:
The system implements feedback mechanisms where the reception duration controller receives information about data errors from the data error detector. Based on this feedback, the system adjusts the reception duration accordingly. This feedback loop enables the system to respond to actual communication quality, extending reception only when necessary to correct errors, thus reducing overall communication time while maintaining intermittent reception power savings.
2Reliability
If reception duration is extended to handle data errors, then data reception reliability is improved, but power consumption increases
Solution Approach 1:
The reception duration is dynamically adjusted based on actual data error conditions rather than being permanently extended. The system extends reception duration only when and as long as data errors are detected, then returns to the original intermittent reception pattern. This dynamic approach ensures reliable data reception when needed while minimizing power consumption during error-free communication periods.
Solution Approach 2:
The system changes the reception duration parameter in response to data error conditions. When errors are detected, the reception duration parameter is increased to allow for retransmission reception. When no errors occur, the parameter returns to its minimum value. This parameter adjustment strategy balances reliability requirements with power consumption constraints.
3Use of energy by moving object
If fixed intermittent reception intervals are used, then power consumption is minimized, but communication completion time increases when errors occur
Solution Approach 1:
The reception duration is made dynamic to adapt to communication conditions. Instead of fixed intervals, the system extends reception duration when data errors are detected, allowing for immediate retransmission reception without returning to idle state. This dynamic adjustment accelerates communication completion when errors occur while maintaining power-saving intermittent reception during normal operation.
Solution Approach 2:
The system maintains continuous reception action when data errors are detected, rather than interrupting to enter idle state. By extending the reception duration continuously through error conditions, the system ensures that retransmissions are captured without interruption, improving communication completion speed while minimizing the impact on overall power consumption.

AI summary
A handset 2 comprises a transceiver 3 configured to transmit and receive data to and from a base 1, a data error detector 5 configured to determine whether or not there is an error in the data received by the transceiver 3, and a reception duration controller 8 configured to change a specific reception duration. If the data error detector 5 has determined that there is an error, the reception duration controller 8 extends a reception duration of the transceiver 3 so as to receive the data newly sent from the base 1. This cuts down on unnecessary calling repetition between the base 1 and the handset 2, and on wasted waiting time.
