Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless networks face challenges in providing reliable data transmission to devices in crowded and congested areas due to obstructions and transient disturbances, which can lead to data loss and increased error rates.
Innovation Solution
The system distributes data transmission across different antenna sets on multiple base stations using a pseudo-random distribution pattern, ensuring spatial diversity and minimizing the impact of obstructions by routing alternate groups of data bits through various transmission paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data transmission is concentrated on a single base station or antenna set, then the transmission path is simple and device complexity is reduced, but reliability deteriorates due to obstructions and transient disturbances
Solution Approach 1:
The patent segments the data transmission by dividing data bits into groups and distributing them across multiple antenna sets from different base stations. This segmentation allows the system to achieve diversity gain without requiring a single complex transmission path, thereby improving reliability while managing complexity through modular distribution.
Solution Approach 2:
The patent combines multiple transmission paths from different base stations and antenna sets into a unified data transmission system. By merging these diverse paths, the system achieves spatial diversity and improves reliability against obstructions and disturbances while the coordination mechanism manages the overall complexity.
2Reliability
If data is transmitted through multiple antenna sets on different base stations, then spatial diversity is improved and reliability is enhanced, but device complexity increases due to coordination requirements
Solution Approach 1:
The patent introduces a network controller as an intermediary that coordinates the transmission activities of multiple base stations and antenna sets. This mediator manages the distribution of data groups across different antenna sets, handling the coordination complexity centrally while allowing individual base stations to operate with simpler local functions.
Solution Approach 2:
The patent implements dynamic selection and distribution of data groups across antenna sets based on current network conditions and interference patterns. This dynamic approach allows the system to adapt to changing environments, optimizing reliability while the flexibility reduces the need for overly complex static coordination mechanisms.
3Reliability
If transmission paths are diversified across multiple base stations, then the impact of obstructions is minimized and reliability is improved, but the system complexity and coordination overhead increase
Solution Approach 1:
The patent segments the data stream into multiple groups that can be transmitted through different spatial paths. This segmentation enables the system to recover from obstructions affecting specific paths while the network controller manages the distribution, achieving error correction capability without requiring complex coordination of every individual data bit.
Solution Approach 2:
The patent changes the spatial parameters of transmission by varying which antenna sets transmit which data groups based on detected interference and obstruction patterns. This parameter adjustment allows the system to maintain reliability by adapting to environmental conditions while avoiding the need for complex permanent configurations.

AI summary
A network controller is configured to receive a data packet from a core network for routing to a device in a wireless network. The controller may then select an antenna set from a plurality of antenna sets that are distributed across different base stations operable to transmit data packets to the destination device. The antenna set may be selected from the plurality of antenna sets based on a distribution pattern. For example, the distribution pattern may be a pseudo-randomly generated distribution pattern. The controller may then route the at least one data packet to the base station which the selected antenna set is implemented for transmission to the device. The antenna sets may be implemented on one base station, or implemented so that the antennas of an antenna set are distributed across multiple base stations. The antenna sets may also be configured to be of any number of antennas.
