Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently identifying and managing user equipment (UE) in complex network environments, particularly in scenarios involving multiple access technologies and diverse network nodes, which can lead to interference and inefficient resource allocation.
Innovation Solution
Implementing a method where UEs reflect signals with modulation indicating their identification to network nodes, and network nodes receive these reflections, enabling more precise identification and management of UEs through techniques such as beamforming and MIMO antenna technology.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional wireless communication methods are used for UE identification, then the system can maintain simple architecture, but the UE identification accuracy and resource allocation efficiency deteriorate in complex network environments
Solution Approach 1:
The patent introduces a reflector as an intermediary device that receives downlink signals from the network node and reflects them back with embedded UE identification information. This mediator approach allows the UE to indirectly communicate its identity without requiring complex direct transmission mechanisms, thereby improving identification accuracy while maintaining relative system simplicity.
Solution Approach 2:
The system implements a feedback mechanism where the UE reflects the received downlink signal back to the network node with modulated identification information. This feedback loop enables the network to accurately identify the UE based on the reflected signal characteristics, improving measurement precision through a structured interaction protocol.
2Adaptability or versatility
If multiple access technologies are deployed to support diverse communication needs, then system versatility improves, but interference and resource allocation efficiency deteriorate
Solution Approach 1:
The patent applies local quality by enabling the reflector to modulate the reflected signal with UE-specific identification information. Each UE's signal carries unique local characteristics (modulation pattern) that allow the network to distinguish between multiple UEs sharing the same spatial resource, thereby reducing interference while maintaining versatility.
Solution Approach 2:
The system uses signal modulation as an analog to 'color changes' - different UEs are distinguished by their unique modulation characteristics (signal 'color') rather than spatial separation. This allows multiple UEs to share the same physical space and time resources while maintaining distinguishability, reducing interference in diverse network environments.
3Productivity
If traditional signal transmission is used without reflection, then the system architecture remains simple, but spectral efficiency and resource allocation improve when reflection with modulation is implemented
Solution Approach 1:
The reflector performs self-service by automatically modulating the reflected signal with UE identification information without requiring separate transmission operations. The UE leverages the existing downlink signal infrastructure to convey its identity, achieving spectral efficiency improvements while avoiding the need for additional complex transmission hardware.
Solution Approach 2:
The reflected signal serves multiple functions simultaneously: it provides UE identification, confirms signal reception, and enables resource allocation. This multi-functionality approach improves spectral efficiency by consolidating multiple communication tasks into a single reflected signal, avoiding the need for separate dedicated channels.
