Downlink Rate Matching for Synchronization Signal Blocks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional downlink channel rate matching solutions in new radio wireless communication systems do not provide sufficient speed or customization for efficient network operation, leading to suboptimal utilization of resources and potential conflicts with control regions.
Innovation Solution
The method involves determining the number of synchronization signal blocks available for transmission and transmitting an indication on a downlink channel to utilize unused or available resource elements for data transmission, allowing for dynamic rate matching and efficient resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional downlink channel rate matching solutions are used, then the system maintains basic operation, but resource utilization is suboptimal and conflicts with control regions occur
Solution Approach 1:
The patent implements dynamic rate matching by determining the actual locations of synchronization signal blocks (SSBs) based on received indications from the network entity. The UE adapts its rate matching behavior in real-time based on dynamic SSB locations rather than using fixed predetermined patterns, thereby improving resource utilization without excessive complexity
Solution Approach 2:
The system changes the parameter of SSB locations from fixed/predetermined to dynamic/indicated. The network entity transmits indications of actual SSB locations, and the UE uses these location parameters to adjust its rate matching accordingly, resolving the contradiction between utilization efficiency and complexity
2Productivity
If dynamic rate matching is implemented to improve resource utilization, then efficiency increases, but the system requires additional indication transmissions and processing
Solution Approach 1:
The indication mechanism serves multiple functions: it informs the UE of SSB locations for rate matching purposes, and simultaneously provides location information that prevents conflicts with control regions. This multi-functionality reduces the need for separate control information transmissions
Solution Approach 2:
The patent uses an indication message as an intermediary that carries location information. This intermediary enables the network to communicate SSB locations to the UE efficiently, allowing dynamic rate matching without requiring complex direct coordination or additional separate control channels
3Ease of operation
If fixed predetermined SSB locations are used, then the system operation is simple, but resource elements may be wasted or conflict with control regions
Solution Approach 1:
The system transitions from static predetermined SSB locations to dynamic indicated locations. The UE determines SSB locations based on received indications rather than using fixed patterns, enabling flexible adaptation to actual network conditions and improving resource element utilization while maintaining operational simplicity through standardized procedures

AI summary
A configurable new radio (NR) resource scheduling and indication transmission procedure that may be executed by a base station and a user equipment (UE) is disclosed. For example, a base station may determine a number of synchronization signal blocks available for transmission of non-scheduling data, and transmit an indication signifying at least one of the number of synchronization signal blocks or a location of each of the number of synchronization signal blocks. Further, a UE may receiving an indication signifying at least one of a number of synchronization signal blocks or a location of each of the number of synchronization signal blocks. The UE may further determine one or more resource elements forming the number of synchronization signal blocks where non-scheduling data has been scheduled for transmission. The UE may receive the non-scheduling data within the one or more resource elements forming the number of synchronization signal blocks.
