Adaptive Reply Timer Setting for AIoT Communication Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems, particularly in zero-power communication scenarios, there is a challenge in determining the duration for waiting for a reply from a peer device, leading to erroneous determinations that the peer end is unable to reply due to the longer processing times of devices like AIoT terminals.
Innovation Solution
A communication method where devices exchange information to determine a feedback duration for a timer, which is started when a request message is sent, allowing the network to adjust its waiting time based on the capabilities of the terminal device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the network side uses a fixed short waiting time for reply messages, then the communication efficiency is improved, but AIoT terminals with longer processing times are erroneously determined as unable to reply
Solution Approach 1:
The patent applies dynamics by making the timer value adjustable rather than fixed. The network side device can dynamically adjust the timer value based on terminal capabilities (AIoT terminal vs. other terminals). When an AIoT terminal is detected, a longer timer value is used to accommodate its slower processing speed, preventing erroneous determination that the terminal cannot reply. This resolves the contradiction by allowing the system to maintain high efficiency for fast terminals while providing sufficient waiting time for slower AIoT terminals.
Solution Approach 2:
The patent changes the parameter of timer value based on terminal type. The network side device determines whether the terminal is an AIoT terminal and adjusts the timer parameter accordingly - using a first timer value for AIoT terminals and a second timer value for other terminals. This parameter change allows the system to adapt to different terminal processing speeds, ensuring reliable reply determination for all terminal types while maintaining overall communication efficiency.
2Reliability
If the network side extends the waiting time for AIoT terminals, then the reliability of reply determination is improved, but the communication efficiency deteriorates due to longer waiting periods
Solution Approach 1:
The patent applies local quality by applying different timer values to different terminal types rather than using a uniform timer for all terminals. AIoT terminals receive a longer timer value (first timer value) to ensure reliable reply determination, while other terminal types receive a shorter timer value (second timer value) to maintain communication efficiency. This localized differentiation resolves the contradiction by providing extended waiting time only where necessary (for AIoT terminals) without impacting the efficiency of communications with faster terminals.
Solution Approach 2:
The system dynamically adjusts the timer value based on the terminal capability identification. When an AIoT terminal is detected, the timer is extended to ensure reliable reply determination. For other terminals, the timer remains short to maintain efficiency. This dynamic adaptation resolves the contradiction between reliability and efficiency by matching the waiting time to the actual processing capabilities of the communicating terminal.
3Reliability
If the network side uses a long waiting time for all terminals, then all terminals can reply without error, but the communication efficiency is reduced due to unnecessary waiting
Solution Approach 1:
The patent changes the timer parameter based on terminal type identification. The network side device uses a first timer value (longer) for AIoT terminals and a second timer value (shorter) for other terminals. This parameter differentiation ensures that AIoT terminals are given sufficient time to reply without error, while other terminals do not experience unnecessary waiting time loss. This resolves the contradiction by applying extended waiting time only to terminals that require it.
Solution Approach 2:
The system applies different waiting time qualities to different terminal types. AIoT terminals receive localized extended waiting time to ensure reliable reply determination, while other terminals experience standard waiting time without unnecessary delays. This local differentiation resolves the contradiction between reliability and time loss by providing extended waiting periods only where actually needed.
