Base Station DU SSB Timing Report for CU Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently coordinating the transmission timing of cell-defining synchronization signal blocks (CD-SSBs) between base station distributed units (DUs) and control units (CUs), leading to potential overlaps in SSB transmission and measurement.
Innovation Solution
A method where a base station DU configures and transmits a report to a CU identifying the transmission timing of CD-SSBs within a radio frame, allowing the CU to efficiently coordinate radio resource usage and avoid conflicts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base station DU transmits CD-SSBs without coordinated timing information, then the transmission can proceed independently, but overlaps with measurement operations may occur causing interference
Solution Approach 1:
The base station DU provides feedback to the base station CU by transmitting a report containing SSB transmission timing information. This feedback mechanism enables the CU to coordinate radio resource allocation and prevent transmission overlaps with measurement operations, thereby eliminating interference while maintaining transmission reliability.
2Productivity
If the base station CU allocates radio resources without timing information, then resource allocation can be performed independently, but conflicts with SSB transmission timing may occur
Solution Approach 1:
The base station DU performs preliminary action by determining and reporting SSB transmission timing information to the base station CU before radio resource allocation is finalized. This allows the CU to advance plan resource allocation to avoid conflicts with SSB transmission, thereby improving resource allocation efficiency while preventing resource conflicts.
3Measurement precision
If detailed SSB transmission timing information is reported to the CU, then coordination precision is improved, but the complexity of the reporting mechanism increases
Solution Approach 1:
The invention extracts only the essential SSB transmission timing information needed for coordination and includes it in a dedicated report transmitted from the base station DU to the base station CU. By extracting and reporting only the necessary timing parameters rather than complete configuration details, the mechanism achieves precise timing coordination while minimizing reporting complexity.
