Reference Signal Prioritization for Overlapping Sensing and Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently multiplexing sensing and communication signals due to overlapping reference signals, leading to simultaneous measurement limitations, which affect channel estimation and overall spectral efficiency.
Innovation Solution
Implementing methods and apparatuses for prioritizing between sensing reference signals (S-RS) and communication signals (e.g., RRM/RLM RSs) by determining which signal to measure when overlaps occur, allowing for simultaneous channel estimation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If sensing signals and communication signals are multiplexed in the same time-frequency resources, then spectral efficiency is improved, but measurement conflicts occur when reference signals overlap
Solution Approach 1:
The patent changes the measurement timing parameter by determining that the wireless device should measure either the sensing reference signal or the communication reference signal based on overlap detection, resolving the measurement conflict while maintaining resource multiplexing
Solution Approach 2:
The patent introduces an intermediary decision mechanism that selects which reference signal to measure when overlap occurs, acting as a mediator between the conflicting sensing and communication measurement requirements
2Measurement precision
If the wireless device measures both sensing reference signals and communication reference signals simultaneously, then channel estimation for both functions is achieved, but device complexity and processing burden increase
Solution Approach 1:
The patent applies partial action by measuring only one reference signal (either sensing or communication) when overlap occurs, rather than attempting to measure both simultaneously, reducing processing complexity while maintaining necessary channel estimation for the prioritized function

AI summary
Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, an example of a process includes receiving a multiplexed signal, where at least a portion of a sensing signal scheduled within the multiplexed signal overlaps in time with at least a portion of a communication signal scheduled within the multiplexed signal. The process can further include determining whether to measure one of the sensing signal or the communication signal to obtain measurements for channel estimation.
