Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in smoothly providing various services due to inefficiencies in transmitting and receiving control information, particularly in 5G and IoT networks, where dynamic resource allocation and channel state feedback are not optimized.
Innovation Solution
A method and apparatus for dynamic precoding resource block (PRB) bundling are introduced, where the size of the PRG is dynamically determined based on downlink control information (DCI) and bandwidth part allocation, allowing flexible resource allocation for improved service provision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If dynamic precoding resource block bundling is implemented with flexible PRG size configuration, then resource allocation efficiency and service quality are improved, but control information transmission complexity increases
Solution Approach 1:
The patent applies dynamics by enabling dynamic configuration of precoding resource block group (PRG) sizes based on actual transmission needs. The base station can flexibly adjust PRG sizes (e.g., 2 PRBs, 4 PRBs, or other configured sizes) according to channel conditions and service requirements, allowing the system to adapt to varying productivity needs while managing complexity through predefined configuration options
Solution Approach 2:
The patent implements parameter changes by modifying the PRG size parameter dynamically. Instead of using fixed PRG sizes, the system changes the PRG size parameter based on transmission conditions, service type (eMBB, mMTC, URLLC), and channel state information. This allows optimization of resource allocation efficiency while containing complexity through structured parameter variation
2Reliability
If PRG size is dynamically determined based on DCI and bandwidth part allocation, then service quality for different communication types is improved, but channel state feedback overhead increases
Solution Approach 1:
The patent applies local quality by determining PRG sizes differently for different bandwidth parts and service types. Each bandwidth part can have its own PRG size configuration optimized for local channel conditions and service requirements. This allows high service quality for critical services like URLLC in specific bands while reducing feedback overhead in other bands where different PRG sizes are more suitable
Solution Approach 2:
The patent implements partial action by selectively applying dynamic PRG size determination only where necessary. Instead of always using maximum flexibility, the system applies dynamic PRG configuration based on actual transmission needs, service type, and channel conditions, thereby achieving sufficient service quality while minimizing feedback overhead through selective application
3Adaptability or versatility
If flexible bandwidth part allocation is implemented, then adaptability to different service requirements is improved, but resource management complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the total bandwidth into multiple bandwidth parts (BWPs), each of which can be independently configured with different PRG sizes. This segmentation allows the system to allocate different PRG configurations to different service types within the same carrier, improving adaptability while managing complexity through modular, independent configuration of each segment
Solution Approach 2:
The patent implements universality by creating a unified framework that handles multiple service types (eMBB, mMTC, URLLC) through a common PRG size configuration mechanism. The same basic framework of dynamic PRG determination based on DCI and bandwidth part allocation serves all service types, improving adaptability while avoiding the need for separate complex management systems for each service
