Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User devices often struggle to establish strong connections with networks due to distance or obstructions, and as wireless communication standards evolve, this leads to increased power consumption without optimizing the transmit and receive paths.
Innovation Solution
Separate the transmit and receive paths in a single communication session by determining optimal nodes for each function, allowing the user device to transmit via the optimal transmit node and receive via the optimal receive node, even if they are different.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a user device connects to a single access point for both transmitting and receiving data, then the connection establishment is simple, but the throughput and capacity are limited when the optimal transmit and receive nodes differ
Solution Approach 1:
The patent segments the data transmission path by separating the transmit path from the receive path. The user device can transmit upstream data via a first node while receiving downstream data via a second node, allowing independent optimization of each path. This segmentation enables the device to connect to different nodes for different functions, maximizing throughput without requiring a single optimal node for both directions.
Solution Approach 2:
The patent introduces an additional dimension to the connection architecture by allowing the user device to maintain simultaneous connections to multiple nodes for different purposes. Instead of a single-dimensional connection to one access point, the device can connect to a first node for transmission and a second node for reception, effectively adding a dimensional layer to the network topology that enables parallel optimization of transmit and receive paths.
2Use of energy by moving object
If the user device transmits and receives via the same node, then the connection management is simple, but the power consumption increases when the optimal node for transmission differs from the optimal node for reception
Solution Approach 1:
The patent segments the communication paths to allow independent optimization of transmit and receive nodes. By separating the first node (optimal for transmission) from the second node (optimal for reception), the system enables the user device to transmit and receive via different nodes, reducing the power required for transmission while maintaining reception quality. This segmentation allows the device to minimize power consumption by selecting the most energy-efficient node for each function.
Solution Approach 2:
The patent applies local quality optimization by selecting different nodes based on their specific strengths for different functions. The first node is selected specifically for its suitability for transmission (local quality for transmit), while the second node is selected for its suitability for reception (local quality for receive). This allows each node to be optimized for its specific role, improving overall energy efficiency.
3Productivity
If multiple nodes are used for transmit and receive paths, then the throughput is maximized, but the difficulty of detecting and measuring optimal nodes increases
Solution Approach 1:
The patent implements feedback mechanisms where the system monitors communication quality metrics for multiple nodes and uses this feedback to dynamically select the optimal first node for transmission and second node for reception. By continuously measuring signal strength, interference levels, and other quality parameters, the system can identify and adapt to the best nodes for each function, making the complex multi-node selection process manageable through real-time feedback.
Solution Approach 2:
The patent performs preliminary detection and measurement of multiple nodes before establishing the transmit and receive paths. The system proactively identifies suitable first nodes and second nodes by measuring their characteristics in advance, storing this information for future use. This preliminary action reduces the complexity of real-time node selection by pre-characterizing available nodes and their suitability for different functions.

AI summary
Methods and systems for network optimization are disclosed. Wireless attribute data associated with a network may be used to determine a first path through the network for receiving downstream data of a communication session by a user device and a second path through the network for transmitting upstream data of the same communication session by the user device. Separating the transmit and receive paths of a single communication session enables the user device to transmit via the optimal transmit path and receive via the optimal receive path, even if the optimal transmit node and optimal receive node are different.
