Wireless Polling Procedure Dynamic Triggering Buffer Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, the polling procedure for data retransmission often wastes radio resources and can lead to buffer saturation if not managed efficiently, potentially causing unexpected communication breakdowns.
Innovation Solution
A method is introduced to trigger and terminate the polling procedure based on predetermined events, such as receiving status reports, and to perform the polling procedure when the buffer occupancy ratio exceeds a certain threshold, ensuring timely and efficient use of radio resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the polling procedure is performed frequently to ensure timely detection of transmission status, then the reliability of data transmission is improved, but the radio resources are wasted
Solution Approach 1:
The polling procedure transitions from a static periodic execution to a dynamic event-triggered execution. The transmitting side adapts the polling timing based on real-time conditions such as buffer occupancy thresholds and reception of status reports, performing polling only when necessary rather than at fixed intervals.
Solution Approach 2:
The system implements feedback mechanisms where the transmitting side monitors buffer occupancy levels and receives status reports from the receiving side. This feedback information drives the decision-making process for when to initiate polling procedures, creating a closed-loop control system that responds to actual transmission needs.
2Loss of energy
If the polling procedure is delayed to save radio resources, then the radio resource usage is improved, but the buffer may become saturated causing communication breakdown
Solution Approach 1:
The transmitting side proactively monitors buffer occupancy levels and initiates polling procedures when predefined thresholds are reached, before the buffer becomes completely saturated. This preliminary action prevents communication breakdown by detecting transmission issues early while still maintaining radio resource efficiency.
3Loss of time
If the polling procedure is performed periodically to ensure timely status detection, then the response time is improved, but the radio resources are consumed unnecessarily when no retransmission is needed
Solution Approach 1:
The system combines periodic monitoring of buffer conditions with event-triggered polling. While buffer occupancy is monitored continuously, actual polling procedures are triggered by specific events such as reaching threshold levels or receiving status reports, rather than executing polling at every fixed time interval.

AI summary
A method of performing a polling procedure in a wireless communication system is disclosed. In a method of performing polling procedure in a protocol layer in a wireless communication system, wherein the protocol layer performs a data retransmission function, the method comprises triggering a polling procedure to request a receiving side to transmit a status report, and terminating the triggered polling procedure if a predetermined event occurs.
