Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless cellular networks, certain regions such as building interiors experience degraded signal quality due to penetration losses and scattering, leading to compromised quality of service for user equipment (UE), and existing relay node solutions can only serve specific external networks, requiring separate relay node networks for different external wireless networks.
Innovation Solution
A relay node network that can support multiple external wireless networks operating under different radio access technologies, using unused frequency bands for communication and cooperatively managing radio resources to ensure efficient service without introducing unacceptable interference, allowing the same relay node network to improve coverage for various external wireless networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate relay node networks are used for different external wireless networks, then each external network can be served specifically, but the device complexity and number of relay nodes required increases
Solution Approach 1:
The relay node network is designed to serve multiple external wireless networks operating under different radio access technologies through a single unified infrastructure. The relay nodes can identify and support different external networks and selectively establish connections with user equipment based on network type, eliminating the need for separate dedicated relay networks for each external network while maintaining the ability to provide optimized service for each network type
2Reliability
If relay nodes are deployed to improve coverage in building interiors, then signal quality improves for user equipment, but the risk of introducing interference to external wireless networks increases
Solution Approach 1:
The relay node network implements differentiated service by identifying the specific external wireless network and selectively establishing connections with user equipment based on network type. Different relay nodes or different operational modes can be configured to serve different external networks, allowing localized optimization of signal quality for each network type while containing interference risks to specific geographic areas or network types rather than affecting all external networks uniformly
Solution Approach 2:
The relay node acts as an intermediary between external wireless networks and user equipment in coverage areas. The relay node receives signals from external networks and retransmits them to user equipment while attempting to minimize interference back to the external networks. The system includes mechanisms to monitor and manage interference levels, adjusting relay node operations to maintain reliable service for user equipment while protecting external network operations

AI summary
A wireless relay node network includes a plurality of relay devices wherein each relay device is configured to receive a first wireless signal in a first frequency band, and transmit a second wireless signal derived from the first wireless signal using a first set of network use parameters. The plurality of relay devices includes at least a first relay device and a second relay device. The first relay device is configured to select the first set of network use parameters from network resources available for communicating over the wireless relay node network based, at least in part, on a control signal received from the second relay device. The second control signal identifies a second set of network use parameters used by the second relay device.
