Terminal Receiver Early Address Detection for Lower Power Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in effectively reducing power consumption for terminals powered by batteries, particularly in scenarios requiring frequent bidirectional data interaction, as they continue to receive and process invalid data packets, leading to significant energy waste.
Innovation Solution
A terminal is equipped with a receiver that outputs a trigger signal upon detecting an incorrect destination address in a data packet, prompting the processor to stop receiving the packet, thereby reducing unnecessary power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the terminal continues to receive and process all data packets, then data interaction completeness is maintained, but power consumption increases significantly
Solution Approach 1:
The receiver performs preliminary detection of the destination address field in the data packet before complete reception. By checking whether the destination address matches the terminal's address early in the packet structure, the system can determine packet relevance without processing the entire packet, thus preventing unnecessary power consumption while maintaining reliable data interaction.
2Loss of energy
If the terminal stops receiving packets early upon detecting incorrect destination address, then power consumption is reduced, but risk of missing valid data increases
Solution Approach 1:
The system implements a feedback mechanism where the receiver continuously monitors the destination address field in incoming packets and compares it with the terminal's assigned address. When a match is detected, the terminal continues receiving the complete packet; when no match is found, the terminal stops reception. This feedback-based approach ensures reliable data reception by maintaining accuracy while reducing power consumption through early termination of irrelevant packet reception.

AI summary
Provided is a terminal including a receiver and a processor. The receiver is configured to output a trigger signal in response to receiving a destination address in a data packet; and the processor is configured to, in response to detecting the trigger signal, control the receiver to stop receiving the data packet, in the case that the destination address is not an address of the terminal.
