Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems lack flexibility in radio resource configuration, leading to inefficient utilization of radio resources as they typically support only one radio interface technology per carrier, making it difficult to dynamically adjust requirements and resulting in low radio resource utilization.
Innovation Solution
A method where a base station divides a frequency band of a cell into multiple frequency ranges, each supporting a different radio interface technology, allowing for the configuration of data radio bearers and signaling radio bearers across these ranges, enabling the use of multiple radio interface technologies to improve flexibility and resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If only one radio interface technology is supported on one carrier, then the system structure is simple and easy to implement, but the radio resource utilization is low and flexibility is poor
Solution Approach 1:
The frequency band is divided into multiple frequency ranges, with each frequency range supporting a different radio interface technology. This segmentation allows the system to support multiple radio interface technologies on a single carrier while maintaining manageable complexity through structured organization of frequency resources.
Solution Approach 2:
A single carrier is designed to support multiple radio interface technologies simultaneously by allocating different frequency ranges to different technologies. This multi-functionality enables the same carrier to serve diverse service requirements with different technical characteristics, improving both adaptability and resource utilization.
2Device complexity
If only one radio interface technology is supported on one carrier, then the device complexity is low, but the ability to dynamically adjust radio resource requirements is limited
Solution Approach 1:
The system enables dynamic adjustment of radio resource configuration by allowing different radio interface technologies to be activated or deactivated on different frequency ranges based on service requirements. This dynamic capability permits real-time adaptation to changing resource demands while maintaining a structured framework that manages device complexity.
3Adaptability or versatility
If multiple radio interface technologies are supported on one carrier, then the radio resource utilization improves and flexibility increases, but the device complexity and configuration difficulty increase
Solution Approach 1:
Different frequency ranges are assigned to different radio interface technologies based on local service requirements and technical characteristics. This local quality approach allows each frequency range to be optimized for specific technology requirements while maintaining overall system coordination, thereby managing complexity through localized specialization.
