Innovation Solution
The implementation of a computer-implemented method for dynamic spectrum sharing in wireless communication networks, which involves generating and transmitting control plane messages to identify and manage radio resources, allowing for the simultaneous control of radio units by distributed units operating in different communication networks, such as LTE and 5G NR, through resource element masking and bitmap allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple radio technologies (LTE and 5G NR) share the same frequency spectrum simultaneously, then network capacity and spectral efficiency are improved, but interference between different radio technologies increases and resource coordination becomes more complex
Solution Approach 1:
The patent segments the shared spectrum into distinct resource blocks and applies separate control mechanisms for different radio technologies. Each radio technology (LTE and 5G NR) is allocated specific resource elements within the shared spectrum, allowing simultaneous operation while minimizing interference through structured resource division.
2Adaptability or versatility
If distributed units from different communication networks control the same radio units, then spectrum sharing flexibility and network adaptability are improved, but coordination complexity and control overhead increase
Solution Approach 1:
The patent introduces a resource coordination mechanism that acts as an intermediary between distributed units of different communication networks. This coordinator manages resource allocation and control signaling, enabling multiple distributed units to control the same radio units without direct interference, thus maintaining flexibility while managing complexity through centralized coordination.
3Productivity
If dynamic resource allocation is implemented for spectrum sharing, then resource utilization efficiency is improved, but control plane overhead and signaling complexity increase
Solution Approach 1:
The patent implements preliminary resource element masking where resource allocations are pre-determined and masked before actual data transmission. Control plane messages prepare and distribute resource allocation patterns in advance, allowing dynamic resource utilization during data transmission while minimizing real-time signaling overhead through pre-computed resource assignments.
