Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional RF repeaters lack beam management capabilities, leading to potential degradation of signal-to-noise ratio and interference, and are unable to distinguish between downlink and uplink data, which can hinder wireless communication network performance, especially in environments with obstacles or long distances.
Innovation Solution
Implementing multiple repeater aggregation (MRA) systems that utilize multiple RF repeaters to select optimal communication paths, combine signal copies, enable joint transmission, and employ dynamic beam configuration to enhance wireless communication network coverage, reliability, and throughput, while leveraging smart RF repeaters for advanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If conventional RF repeaters are used to extend wireless communication coverage, then network coverage area is improved, but signal-to-noise ratio degrades and interference increases
Solution Approach 1:
The patent combines multiple RF repeaters into a coordinated system where multiple repeaters work together to transmit and receive signals. This merging approach allows the system to achieve extended coverage while maintaining signal quality through cooperative signal processing and joint transmission techniques.
Solution Approach 2:
The repeater system is designed to perform multiple functions including signal amplification, noise filtering, interference cancellation, and adaptive beamforming. This multi-functionality allows the same hardware infrastructure to address both coverage extension and signal quality maintenance simultaneously.
2Length of stationary object
If conventional RF repeaters are deployed to extend communication range, then transmission distance is improved, but ability to distinguish downlink and uplink data is lost
Solution Approach 1:
The repeater system employs dynamic time-division duplexing where transmission and reception time slots are adaptively adjusted based on traffic conditions. This dynamic approach allows the system to maintain clear distinction between downlink and uplink data while extending transmission distance through coordinated multi-repeater operation.
Solution Approach 2:
The system implements feedback mechanisms where repeaters exchange information about their transmission and reception states with the network controller and each other. This feedback enables proper identification and handling of downlink versus uplink data frames even across extended distances through multiple repeater hops.
3Reliability
If multiple RF repeaters are aggregated to improve coverage, then network reliability is improved, but system complexity increases
Solution Approach 1:
The patent introduces a network controller as an intermediary that centralizes the management and coordination of multiple RF repeaters. This mediator handles complex tasks such as resource allocation, beam management, and interference coordination, thereby improving network reliability while shielding individual repeaters from excessive complexity.

AI summary
A method for variable time division duplex (TDD) data allocation in a communication network including a donor wireless communication node and a plurality of child wireless communication nodes. The method includes (a) determining a highest traffic child wireless communication node of the plurality of child wireless communication nodes, the highest traffic child wireless communication node having a highest data transmission requirement of the plurality of child wireless communication nodes, and (b) allocating data in first TDD data frames to be transmitted between the donor wireless communication node and a first child wireless communication node of the plurality of child wireless communication nodes according to a first data frame allocation, the first data frame allocation including allocating an on-demand portion of the first TDD data frames to data associated with the highest traffic child wireless communication node.
