Transmitter Timing Control for Intermittent Reception Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wireless communication systems face increased power consumption in transmission devices due to the need to match communication with intermittent reception operations of the reception device, leading to longer transmission times.
Innovation Solution
A transmission device equipped with a transmitter, receiver, reception specifier, and transmission/reception controller that synchronizes and controls the timing and duration of signal transmission based on the reception timing of the intermittent reception device, optimizing power usage by adjusting transmission parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the transmission device matches communication to the intermittent reception operation of the reception device, then the reception device can receive signals properly, but the transmission device takes longer to transmit and power consumption rises
Solution Approach 1:
The transmission device performs preliminary actions by transmitting signals before the reception device's intermittent reception periods. The transmission/reception controller determines optimal transmission timing based on the reception device's reception schedule, allowing the transmission device to prepare and send data in advance rather than waiting for reception windows, thereby reducing overall transmission time and power consumption while ensuring reliable reception.
2Reliability
If the transmission device extends active periods to match intermittent reception, then communication reliability is improved, but transmission duration increases and power consumption rises
Solution Approach 1:
The transmission device dynamically adjusts its transmission parameters based on the reception device's intermittent reception schedule. The transmission/reception controller continuously monitors the reception timing and adapts the transmission duration and frequency accordingly, allowing the system to optimize communication reliability while minimizing transmission duration and power consumption through dynamic parameter adjustment.
3Productivity
If the transmission device waits for reception timing to synchronize, then communication efficiency improves, but transmission delay increases
Solution Approach 1:
The transmission device performs preliminary transmission actions by sending signals before the reception device's scheduled reception periods. The transmission/reception controller calculates optimal transmission timing based on the reception schedule, allowing data to be transmitted in advance rather than waiting for reception windows to open, thereby reducing transmission delay while maintaining communication efficiency through proper synchronization.

AI summary
A transmission device (11) comprises a transmitter (13) for transmitting various signals to a reception device (12), a receiver (15) for receiving a response signal emitted from the reception device (12) in response to the transmission of the various signals from this transmitter (13) to the reception device (12), a transmission/reception controller (14) for performing control of the receiver (15) and the transmitter (13), and a reception specifier (16) for specifying the reception timing of the intermittent reception of the reception device (12) when a response signal from the reception device (12) has been received. The transmission/reception controller (14) decides the timing at which the transmission of the various signals will begin, and how long the transmission will last, on the basis of the reception timing specified by the reception specifier (16).
