PRS Beam Prioritization via Index-Based Ordering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in 5G, face challenges in efficiently prioritizing downlink positioning reference signals (PRS) due to the complexity of managing multiple PRS resources and determining optimal beam selection for accurate location estimation.
Innovation Solution
The system utilizes PRS resource index information to facilitate PRS prioritization by determining an assigned beam and adjacent beams based on received beam index information, allowing for improved location measurements by processing a subset of PRS resources ordered by angular proximity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple PRS resources are managed to improve location estimation accuracy, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent segments the PRS beam set into multiple individual PRS resources, each associated with a specific beam index. This segmentation allows the system to manage multiple PRS resources independently while maintaining organized structure through beam index associations, thereby improving location estimation accuracy without overwhelming complexity
Solution Approach 2:
The patent performs preliminary ordering of PRS resources based on beam index information before actual location measurement. By pre-organizing the PRS resources in angular proximity order using beam indices, the system reduces real-time processing complexity while ensuring accurate location estimation can be performed efficiently
2Productivity
If PRS resources are processed in angular proximity order to improve spectral efficiency, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent applies preliminary ordering of PRS resources based on beam index information to arrange them in angular proximity order before processing. This pre-organization enables the system to efficiently process PRS resources in optimal sequence for spectral efficiency without requiring complex real-time decision-making about beam selection
Solution Approach 2:
The system uses beam index information that inherently encodes angular proximity relationships, allowing the PRS resources to self-organize in the correct processing order without requiring external complex control mechanisms. The beam indices themselves provide the sorting criteria, making the system self-organizing and reducing control complexity

AI summary
Disclosed are systems, apparatuses, methods, and non-transitory media for facilitating positioning reference signal (PRS) prioritization by receiving beam index information associated with a PRS beam set. In some aspects, an assigned beam can be determined based on the beam index information. At least one adjacent beam can further be determined to be based on the assigned beam associated with the beam index information. A location measurement can also be determined based on at least one of the assigned beam, or the at least one adjacent beam.
