Wireless Access Point D2D Master Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless network access points face challenges in efficiently selecting a Device-to-Device (D2D) communication master for D2D communication groups, particularly in balancing signal strength and buffer status reporting frequency to optimize network performance and reduce interference.
Innovation Solution
The wireless network access point filters UEs based on signal strength and buffer capacity thresholds, and prioritizes candidates based on buffer status reporting frequency to select the D2D communication master, thereby optimizing communication links and reducing network load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the D2D master is selected based on signal strength alone, then the connection stability is improved, but the buffer status reporting frequency and network efficiency deteriorate
Solution Approach 1:
The patent changes the selection parameters from considering only signal strength to considering multiple parameters including signal strength, buffer capacity, and buffer status reporting frequency. This multi-parameter approach resolves the contradiction by finding a balance between connection stability and network efficiency.
Solution Approach 2:
The patent introduces dynamic reevaluation of D2D master candidates based on changing buffer status and reporting frequency. The system continuously monitors and adjusts the selection criteria, allowing the network to adapt to varying conditions and maintain both stability and efficiency.
2Measurement precision
If more UEs are monitored and evaluated for D2D master selection, then the selection accuracy is improved, but the signaling overhead and processing complexity increase
Solution Approach 1:
The patent segments the D2D master selection process into distinct phases: initial candidate identification based on signal strength, followed by filtering based on buffer capacity, and final selection based on buffer status reporting frequency. This segmentation reduces processing complexity while maintaining selection accuracy.
Solution Approach 2:
The patent performs preliminary filtering of D2D master candidates based on signal strength and buffer capacity thresholds before conducting detailed evaluation. This preliminary action reduces the number of candidates requiring complex analysis, thereby reducing overall processing complexity while maintaining accuracy.

AI summary
A wireless network access point and User Equipment (UEs) communicate over Base Station-to-Device (BS2D) traffic links. The wireless network access point receives status reports from the UEs that form a Device-to-Device (D2D) communication group. The wireless network access point filters the UEs in the D2D communication group based on a signal strength threshold and a buffer capacity threshold to identify a candidate set of the UEs. The wireless network access point further prioritizes the candidate set based on buffer status reporting frequency of the UEs to select one of the UEs as the D2D communication master for the D2D communication group.
