PDCCH Resource Configuration via Segmented CCE-REG Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current 5G NR system lacks a determined method for CCE-REG mapping, leading to resource blocking issues due to overlapping PDCCH/CORESET resources with different sizes, which affects resource allocation efficiency and flexibility.
Innovation Solution
A PDCCH resource configuration method that determines and configures resource configuration information including REG bundle size, CCE-REG mapping manner, and REG mapping manner, allowing for non-interleaved and interleaved mapping to support multiple PDCCH resource configuration modes, reducing blocking probability and improving system flexibility and resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If flexible PDCCH resource allocation is implemented with multiple PDCCH/CORESET configurations, then resource multiplexing rate is improved, but time-frequency resource overlapping occurs causing serious resource blocking
Solution Approach 1:
The patent segments the PDCCH resource configuration by introducing separate control sets (first control set and second control set) with different mapping manners. The first control set uses first mapping manner while the second control set uses second mapping manner, allowing independent resource allocation and avoiding blocking between different control sets.
Solution Approach 2:
The patent applies different mapping manners to different control sets based on their specific requirements. Each control set can be configured with its own mapping manner (interleaved or non-interleaved) to optimize resource allocation for its specific service type, achieving local optimization without affecting other control sets.
2Adaptability or versatility
If CCE-REG mapping manner is not determined, then system flexibility is maintained, but serious resource blocking occurs due to overlapping resources
Solution Approach 1:
The patent makes the mapping manner dynamic and configurable rather than fixed. The network device can dynamically select and configure different mapping manners (interleaved or non-interleaved) for different control sets based on real-time resource allocation needs, maintaining flexibility while preventing resource blocking.
Solution Approach 2:
The patent changes the mapping parameter (mapping manner) as a configurable parameter. By allowing the mapping manner to be changed and configured for different control sets, the system can adapt to different resource allocation scenarios while avoiding the resource blocking issue that occurs with undetermined mapping methods.
3Productivity
If multiple PDCCH/CORESET of different sizes are configured, then resource multiplexing is improved, but time-frequency resources of multiple PDCCH/CORESET overlap each other
Solution Approach 1:
The patent segments the control sets into different groups (first control set and second control set) that use different mapping manners. This segmentation allows the system to allocate resources to different control sets without overlap, as each control set operates with its own mapping strategy.
Solution Approach 2:
The patent introduces a new dimension of differentiation by using different mapping manners (interleaved vs. non-interleaved) as an additional attribute beyond just control set size. This additional dimension allows for more sophisticated resource separation and reduces time-frequency resource overlap.
