Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cellular communication systems are limited by the use of a fixed physical layer basic parameter, which hampers their ability to meet diverse communication service requirements and adapt to varying service and communication environments, leading to reduced system performance due to mutual interference between frequency bands.
Innovation Solution
A communication method where a network device sends configuration information for sub-bands with different physical layer basic parameters to user equipment, allowing them to communicate using these varying parameters, thereby enabling communication service diversity by dynamically configuring sub-bands based on service and environmental requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed physical layer basic parameter is used in a carrier, then system simplicity is maintained, but adaptability to diverse service environments is reduced
Solution Approach 1:
The carrier is divided into multiple sub-bands, each capable of having different physical layer basic parameters. This segmentation allows different parts of the frequency spectrum to use optimized parameters for different services, resolving the contradiction between maintaining simplicity and achieving adaptability.
Solution Approach 2:
The physical layer basic parameters are made dynamic rather than fixed. The network device can dynamically configure different parameters for different sub-bands based on service requirements, enabling the system to adapt to diverse service environments while maintaining manageable complexity through structured configuration.
2Adaptability or versatility
If different physical layer basic parameters are used in different frequency bands, then service diversity is improved, but mutual interference between resources increases
Solution Approach 1:
By segmenting the carrier into sub-bands and assigning different physical layer parameters to different sub-bands, the patent enables service diversity while containing interference within specific frequency segments. This structured segmentation prevents widespread mutual interference across the entire carrier.
Solution Approach 2:
Different physical layer parameters are applied locally to different sub-bands based on their specific service requirements. This local optimization allows each sub-band to have the quality parameters best suited for its intended service, reducing interference by tailoring parameters to local needs rather than applying a uniform configuration.
3Productivity
If a universally applicable compromised parameter is selected, then system compatibility is maintained, but communication performance in diverse environments is reduced
Solution Approach 1:
The patent segments the carrier into multiple sub-bands, each capable of using optimized physical layer parameters tailored to specific services. This eliminates the need for a single universally applicable compromised parameter, allowing each sub-band to achieve optimal communication performance for its intended service type.
Solution Approach 2:
The physical layer basic parameters are changed from fixed to variable, allowing the network device to select and configure different parameters for different sub-bands based on service requirements. This parameter flexibility enables optimal communication performance across diverse service environments rather than relying on a compromised universal parameter.
