SSB Determination for Multi-TRP Signaling Overhead Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communications, especially in downlink multiple Transmission Reception Point (TRP) cooperative transmission, the existing methods require repeated configuration of neighboring cell information, leading to significant signaling overhead due to the assumption that UE can only report RSRP for SSBs within the serving cell, necessitating additional efforts to include non-serving cells.
Innovation Solution
The method determines whether an SSB belongs to a serving cell or a neighboring cell using cell indication information, allowing parameter determination or CSI reporting without repeatedly configuring neighboring cell information, thereby reducing signaling overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the UE is configured to report RSRP for SSBs in neighboring cells, then beam management capability is improved, but signaling overhead increases due to repeated configuration of neighboring cell information
Solution Approach 1:
The patent applies universality by enabling a single configuration of neighboring cell information to serve multiple purposes: both for beam management and for CSI reporting. The network device configures neighboring cell SSB information once, and the UE reuses this configuration for both beam management operations and CSI measurements, eliminating the need for separate configurations and reducing signaling overhead.
Solution Approach 2:
The patent merges the beam management function and CSI reporting function into a single configuration framework. By combining the configuration of neighboring cell SSB information for both purposes, the system achieves resource efficiency and reduces redundant signaling while maintaining both beam management capability and CSI reporting functionality.
2Measurement precision
If neighboring cell information is configured for each signal, then measurement accuracy is improved, but signaling overhead increases
Solution Approach 1:
The patent enables a single configuration of neighboring cell information to serve multiple measurement purposes. The configured neighboring cell SSB information is universally applied for both beam management measurements and CSI reporting measurements, ensuring measurement accuracy without requiring repeated configurations for each signal type.
Solution Approach 2:
The UE performs self-service by reusing the configured neighboring cell information for multiple measurement tasks without requiring additional network configuration. The UE autonomously applies the same configuration for both beam management and CSI reporting, reducing signaling overhead while maintaining measurement precision.

AI summary
Disclosed in the present application are an SSB determination method and apparatus, and a device and a storage medium, wherein same relate to the field of mobile communications. The method comprises: according to cell indication information of a first synchronization signal block (SSB) and first index information of the first SSB, determining the first SSB; and according to the first SSB, determining a large-scale parameter, a beam or the transmission power of a first signal; or, performing CSI reporting on the basis of the first SSB, wherein the cell indication information is used to indicate whether the first SSB is an SSB of a serving cell or an SSB of a neighboring cell, and the first index information is used to indicate the first SSB. A first SSB can be determined according to first index information, so as to determine parameter information of a first signal or perform CSI reporting on the basis of the first SSB, so that the parameter of the first signal can be determined or the CSI reporting can be performed without the need to repeatedly configure information of a neighboring cell again, and signaling overhead is further reduced.
