UE Initialization Rate Matching Around SSB and CORESET Blocks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in utilizing network resources during the initialization process of user equipment (UE) due to the large amount of data transmission required for synchronization and system information, leading to suboptimal resource allocation.
Innovation Solution
Implementing rate matching techniques around synchronization signal blocks (SSBs) and control resource sets (CORESETs) to optimize resource usage, where the UE adjusts its reception to avoid overlapping with SSBs and repurposes certain bits for efficient data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If rate matching is applied around SSBs and CORESETs during UE initialization, then resource utilization efficiency is improved, but device complexity increases due to additional processing requirements
Solution Approach 1:
The patent applies rate matching patterns around SSBs and CORESETs in advance during UE initialization, before actual data transmission begins. By pre-configuring the rate matching behavior and identifying resource block boundaries beforehand, the system improves resource utilization without requiring complex real-time processing during data transmission.
Solution Approach 2:
The patent modifies the rate matching parameters specifically for initialization procedures, using different rate matching patterns (e.g., pattern 0 or pattern 1) depending on the configuration. This allows optimized resource allocation around SSBs and CORESETs while maintaining standard processing for normal operation, thus improving efficiency without permanently increasing device complexity.
2Reliability
If synchronization signal blocks are transmitted with full coverage, then reliability of UE initialization is improved, but network resource consumption increases
Solution Approach 1:
The patent segments the network resources by identifying and excluding specific resource blocks occupied by SSBs and CORESETs from the rate matching process. This allows synchronization signals to be transmitted with full coverage and high reliability while the remaining resources are efficiently utilized for data transmission, preventing waste of network resources.
Solution Approach 2:
The patent applies rate matching selectively only around the specific resource blocks occupied by SSBs and CORESETs, rather than applying blanket resource restrictions across the entire bandwidth. This partial action ensures sufficient resources are allocated for reliable synchronization while avoiding excessive resource consumption.
