SSB-RMSI Multiplexing Patterns for 52.6-71 GHz Resource Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3GPP networks face challenges in defining synchronization signal/physical broadcast channel (SSB) and control resource set (CORESET) multiplexing patterns for frequencies between 52.6 GHz and 71 GHz, which are crucial for high data rate communications, due to limitations in time/frequency resources and unsupported subcarrier spacings, leading to inadequate resources for RMSI PDSCH.
Innovation Solution
Enhanced multiplexing patterns, such as enhanced pattern 2 and pattern 3, are introduced to increase the number of symbols in the time domain without altering the arrangement, allowing for adequate time/frequency resources for RMSI PDSCH by incorporating new symbol configurations and buffering techniques for SSB, CORESET, and PDSCH transmissions.

Engineering Contradiction Analysis
1Quantity of substance
If legacy multiplexing patterns are used for SSB and CORESET, then the arrangement is simple and well-defined, but the time/frequency resources are insufficient for RMSI PDSCH transmissions in the 52.6 GHz to 71 GHz frequency range
Solution Approach 1:
The patent introduces enhanced multiplexing patterns that dynamically adjust the number of symbols in the time domain to accommodate different subcarrier spacings (120 kHz and 240 kHz) required for frequencies between 52.6 GHz and 71 GHz. This allows the system to adapt resource allocation to the specific frequency band and subcarrier spacing being used, rather than being constrained by fixed legacy patterns.
Solution Approach 2:
The patent extends the time domain dimension by introducing additional symbols in the enhanced multiplexing patterns. Specifically, it increases the number of symbols available for RMSI PDSCH transmissions by utilizing buffered symbols and extending the pattern structure beyond the traditional configuration, thereby creating additional resource capacity in the time dimension.
2Quantity of substance
If the number of symbols is increased to provide adequate resources for RMSI PDSCH, then resource sufficiency is improved, but the pattern complexity increases
Solution Approach 1:
The patent segments the multiplexing pattern into distinct components: SSB symbols, CORESET symbols, and RMSI PDSCH symbols. By clearly defining the boundaries and roles of each segment, the system can increase the total number of symbols while maintaining structured organization. The segmentation allows for systematic resource allocation where specific symbol ranges are dedicated to specific functions, reducing the perceived complexity despite the increased total symbol count.
Solution Approach 2:
The patent employs buffering techniques where symbols are pre-allocated and prepared in advance for RMSI PDSCH transmissions. This preliminary action allows the system to have ready-to-use symbol configurations that can be quickly deployed without requiring complex real-time calculations, thereby reducing operational complexity even as the total number of available symbols increases.
