SS Block RMSI Offset Signaling to Reduce Wireless Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems waste resources due to unnecessary scanning for synchronization signal blocks that include remaining minimum system information (RMSI), which can be inefficient and costly in terms of power and bandwidth.
Innovation Solution
Reusing remaining minimum system information (RMSI) configuration bits to signal the location of synchronization signal blocks, allowing devices to determine the location of a second block that includes RMSI based on an offset or indication in a first block that does not contain RMSI.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If devices scan all synchronization signal blocks to find those containing RMSI, then devices can obtain system information, but network resources and device power are wasted due to unnecessary scanning
Solution Approach 1:
The patent applies preliminary action by placing an indicator in the synchronization signal block that pre-announces the presence or location of RMSI. This allows devices to determine beforehand whether a scanned block contains RMSI, eliminating the need to fully process or re-scan blocks that don't contain the desired information, thus saving device power while ensuring reliable system information acquisition.
Solution Approach 2:
The patent introduces an intermediary indicator element within the synchronization signal block that mediates between the block itself and the RMSI content. This indicator acts as a signpost that guides devices to the actual RMSI location without requiring exhaustive scanning, reducing energy consumption while maintaining reliable information acquisition.
2Reliability
If devices scan all synchronization signal blocks to find those containing RMSI, then devices can obtain system information, but scanning time is increased due to unnecessary blocks
Solution Approach 1:
The indicator provides preliminary information about RMSI presence or location before the device needs to search for it. This allows the device to skip unnecessary blocks and directly navigate to blocks containing RMSI, significantly reducing scanning time while ensuring reliable system information acquisition.
Solution Approach 2:
The patent enables skipping of unnecessary synchronization signal blocks by using the indicator to identify blocks that contain RMSI. Devices can rush through the scanning process by jumping over blocks that don't contain the required information, reducing overall scanning time while maintaining reliable information acquisition.
3Device complexity
If synchronization signal blocks are transmitted without indicating RMSI location, then transmission is simpler, but network resources are wasted due to inefficient device scanning
Solution Approach 1:
The patent makes the synchronization signal block multi-functional by embedding an indicator that serves dual purposes: maintaining the basic synchronization function while simultaneously providing RMSI location information. This adds minimal complexity to the signal structure but dramatically reduces network resource consumption by enabling efficient device scanning.
Solution Approach 2:
The patent changes a parameter of the synchronization signal block by incorporating an indicator field that conveys RMSI presence or location information. This parameter addition transforms the block from a simple synchronization carrier to an information-rich signal that guides devices efficiently, reducing network resource waste while maintaining structural simplicity.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first synchronization signal (SS) block that does not include remaining minimum system information (RMSI). The first SS block may indicate an offset for obtaining a second SS block that includes RMSI. The UE may determine a location of the second SS block based at least in part on the offset. Numerous other aspects are provided.
