Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of maintaining satisfactory Quality of Service (QoS) in 5G wireless communication systems, particularly in high-frequency bands, is exacerbated by signal power attenuation and interference due to obstacles, necessitating improved resource management for communication devices.
Innovation Solution
The allocation of radiation boundary volumes to communication devices to manage and optimize communication resources, including space, frequency, and time, thereby reducing interference and enhancing system performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If radiation boundary volumes are allocated to communication devices, then interference between devices is reduced and communication quality is improved, but device complexity and network management overhead increase
Solution Approach 1:
The patent segments the three-dimensional space into multiple radiation boundary volumes, each allocated to a specific communication device. This spatial segmentation allows devices to operate in designated volumes, reducing mutual interference while maintaining communication quality. The segmentation principle directly addresses the contradiction by organizing the network management complexity into structured spatial regions.
Solution Approach 2:
The patent introduces a third dimension (spatial volume) to the traditional two-dimensional frequency-time resource allocation. By allocating radiation boundary volumes in three-dimensional space, the system adds a spatial dimension to resource management, allowing multiple devices to operate simultaneously in different spatial regions without interference, thus improving communication quality without proportionally increasing management complexity.
2Reliability
If multi-antenna systems are used to focus radiation power, then channel-induced attenuation is reduced, but the system complexity and hardware requirements increase
Solution Approach 1:
The patent applies local quality by focusing radiation power through beamforming in specific spatial directions defined by the allocated radiation boundary volumes. Each device's antenna system is configured to concentrate energy in the designated volume, improving signal reception quality locally. This principle allows the system to manage the complexity of multi-antenna configurations by optimizing them for specific spatial regions rather than omnidirectional coverage.
3Ease of manufacture
If frequency resources are allocated based on traditional methods, then allocation simplicity is maintained, but interference and attenuation in harsh environments increase
Solution Approach 1:
The patent introduces dynamic spatial allocation of radiation boundary volumes that can adapt to the positions and movement of communication devices. The allocated volumes are updated based on real-time device locations, allowing the system to dynamically adjust resource allocation to maintain optimal communication performance. This dynamic approach manages the complexity by automating the adaptation process based on device status information.
