SSB Kssb Field Extended SCS Indication for 5G RMSI
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in 5G, face limitations in indicating sub-carrier space (SCS) combinations for transmission resources associated with remaining minimum system information (RMSI), as existing SCS indication bits cannot accommodate the increased options with higher frequency bands, leading to reduced flexibility and compatibility issues.
Innovation Solution
The method involves sending a synchronization signal block (SSB) with extended SCS indication information that occupies at least one bit of the Kssb field, allowing for multiple bit occupancy to indicate multiple SCS combinations, thereby increasing the number of indicated SCS combinations and enhancing flexibility in SCS configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing SCS indication bits are used, then the system maintains simplicity and compatibility, but the number of indicated SCS combinations is limited and flexibility is reduced
Solution Approach 1:
The patent segments the Kssb field into multiple parts, with specific bits allocated for extended SCS indication. This segmentation allows the system to indicate multiple SCS combinations (e.g., 4 combinations using 2 bits) while maintaining a structured and manageable bit occupancy format, resolving the contradiction between increased adaptability and device complexity.
Solution Approach 2:
The patent extends the SCS indication capability by adding another dimension to the bit occupancy structure. Instead of using a single bit, the invention utilizes multiple bits within the Kssb field to indicate SCS combinations, effectively increasing the information capacity and flexibility without fundamentally changing the overall system architecture.
2Adaptability or versatility
If multiple bits of Kssb field are occupied for extended SCS indication, then flexibility in SCS configurations is enhanced, but the complexity of bit occupancy increases
Solution Approach 1:
The patent applies local quality by assigning specific bits within the Kssb field to extended SCS indication purposes. For example, certain bit positions are dedicated to indicating SCS combinations, while other bits maintain their original functions. This localized approach enhances flexibility in SCS configurations without unnecessarily complicating the entire bit occupancy structure.
Solution Approach 2:
The patent changes the parameter of bit occupancy from a single bit to multiple bits within the Kssb field. This parameter change enables the indication of multiple SCS combinations (e.g., 4 combinations with 2 bits) and provides greater flexibility in SCS configurations, while the structured approach to parameter change keeps the complexity manageable.
3Adaptability or versatility
If extended SCS indication information is implemented, then compatibility across different frequency bands is improved, but the existing bit structure becomes insufficient
Solution Approach 1:
The patent makes the Kssb field multi-functional by using its bits for both original purposes and extended SCS indication. This universal approach allows the same bit structure to support multiple frequency bands and SCS combinations, improving compatibility across different frequency bands while utilizing existing structural elements rather than creating entirely new structures.
Solution Approach 2:
The patent performs preliminary action by pre-defining the bit occupancy structure within the Kssb field for extended SCS indication. This preliminary configuration enables the system to accommodate multiple SCS combinations and different frequency bands from the outset, avoiding the need for complex dynamic reconfiguration and maintaining compatibility across various scenarios.
