Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in improving positioning precision due to limitations in processing discontinuous Positioning Reference Signals (PRS), which are not specified in current protocols, leading to restricted valid bandwidth and suboptimal measurement capabilities.
Innovation Solution
A method and apparatus for simultaneously processing first reference signal resources across multiple positioning frequency layers, allowing for aggregation or separate processing to enhance valid bandwidth and improve positioning precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a terminal processes discontinuous PRS resources from multiple frequency layers, then the valid bandwidth of PRS increases and positioning precision improves, but the protocol currently does not specify how to process such discontinuous PRS, leading to processing complexity and implementation uncertainty
Solution Approach 1:
The patent segments the discontinuous PRS resources into multiple continuous frequency domain resources from different frequency layers. By dividing the overall PRS processing into layer-specific continuous processing units, the terminal can handle each layer independently using existing continuous PRS processing capabilities, thereby reducing overall processing complexity while maintaining improved positioning precision through aggregated bandwidth
Solution Approach 2:
The patent introduces a frequency layer dimension to organize discontinuous PRS resources. Instead of processing discontinuous resources within a single frequency domain, the solution distributes PRS resources across multiple frequency layers, transforming the problem from a one-dimensional discontinuous resource challenge into a multi-dimensional structured processing approach that leverages continuous resources within each layer
2Measurement precision
If the valid bandwidth of PRS is increased to improve positioning precision, then more frequency resources are required, but configuring PRS on discontinuous frequency domain resources lacks protocol specification and reduces processing efficiency
Solution Approach 1:
The patent merges continuous PRS resources from multiple frequency layers to achieve an effective aggregated bandwidth increase for positioning. By combining the bandwidth contributions from each frequency layer, the system attains the benefits of wide bandwidth (improved precision) while maintaining continuous resource structure within each layer (preserved processing efficiency)
