Wireless Node Frame Reservation for Overlapping Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication, interference between transmissions from multiple wireless nodes reduces data throughput, and existing technologies struggle to effectively manage synchronization and retransmissions across overlapping networks.
Innovation Solution
The solution involves a wireless node that negotiates reservation parameters and synchronization adjustments to minimize interference by determining master-slave roles, reserving transmission and retransmission frames, and correcting phase differences between overlapping networks, allowing for efficient data transmission and synchronization.

Engineering Contradiction Analysis
1Adaptability or versatility
If a wireless node communicates with multiple wireless nodes simultaneously, then communication versatility is improved, but transmission interference increases reducing throughput
Solution Approach 1:
The patent segments the communication timeline into distinct frames with different roles (master frames and slave frames). The wireless node alternates between master and slave roles in different frames, allowing simultaneous communication with multiple nodes without interference by separating transmissions in time domains.
Solution Approach 2:
The patent implements periodic role reversal between master and slave nodes at frame boundaries. This periodic action creates a structured communication pattern where interference is minimized by ensuring that when one node transmits as master, other nodes transmit as slaves in their designated frames, and vice versa in alternating periods.
2Reliability
If transmission frames are reserved for multiple wireless nodes, then communication reliability is improved, but frame synchronization complexity increases
Solution Approach 1:
The patent performs preliminary role assignment and frame reservation during the connection establishment phase. Nodes negotiate and agree on their master/slave roles and frame structures before actual data transmission begins, which simplifies subsequent synchronization and reduces complexity during active communication.
Solution Approach 2:
The patent allows dynamic role reversal between master and slave at frame boundaries based on predetermined patterns. This dynamic switching is managed through simple role indicators in frame headers, allowing nodes to adapt their transmission roles periodically without complex real-time negotiation, maintaining reliability while controlling synchronization complexity.

AI summary
A first wireless node may determine that a first reserved retransmission frame overlaps with a second reserved transmission frame and a second reserved retransmission frame and that the second reserved transmission frame overlaps with a first reserved transmission frame and the first reserved retransmission frame. The first reserved transmission frame and the first reserved retransmission frame may be reserved for wireless communication with a first master node, and the second reserved transmission frame and the second reserved retransmission frame are reserved for wireless communication with a second master node. The wireless node may also process and acknowledge data received from the first master node during the first reserved transmission frame based on the determining, ignore data sent by the second master node during the second reserved transmission frame based on the determining, and process and acknowledge data received from the second master node during the second reserved retransmission frame.
