Innovation Solution
A method and system for selecting a measurement window type for positioning reference signal (PRS) processing and measurement gaps (MG) based on specific criteria, involving the configuration of a PRS processing window (PPW) and MG, which overlap in the time domain, to optimize measurement processing for user equipment (UE) and network components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a positioning reference signal (PRS) processing window (PPW) and measurement gap (MG) are configured to overlap in time domain, then positioning accuracy is improved, but measurement processing complexity increases
Solution Approach 1:
The patent introduces dynamic selection of measurement window types (first and second measurement window types) based on the specific time-domain overlap characteristics between PPW and MG. The system adapts the measurement processing method according to the actual configuration, choosing between different window types to optimize the balance between positioning accuracy and processing complexity for each scenario.
Solution Approach 2:
The patent changes the parameter of measurement window type selection based on the time-domain overlap between PPW and MG. By selecting different measurement window types (first or second type) according to the specific overlap characteristics, the system adjusts processing parameters to achieve optimal positioning accuracy while managing complexity.
2Productivity
If measurement processing is performed using a fixed measurement window type, then device complexity is reduced, but positioning efficiency decreases
Solution Approach 1:
The system transitions from a fixed measurement window type to a dynamic selection mechanism that adapts to the specific time-domain overlap characteristics between PPW and MG. This dynamic approach optimizes positioning efficiency for each scenario while keeping the processing logic manageable through defined selection criteria.
Solution Approach 2:
The patent changes the measurement window type parameter based on the time-domain overlap characteristics. By selecting the appropriate window type (first or second) according to the specific PPW-MG configuration, the system optimizes positioning efficiency without requiring overly complex processing for all possible scenarios.
3Measurement precision
If the measurement window is extended to cover the entire PPW-MG overlap period, then positioning accuracy is improved, but measurement processing time increases
Solution Approach 1:
The patent introduces dynamic measurement window type selection based on the specific time-domain overlap characteristics between PPW and MG. The system adapts the measurement processing duration and window type to the actual overlap scenario, avoiding unnecessary extended processing while ensuring sufficient accuracy for each specific case.
Solution Approach 2:
The patent changes the measurement window parameter dynamically based on the time-domain overlap characteristics. By selecting different window types according to the specific PPW-MG configuration, the system optimizes the balance between positioning accuracy and processing time for each scenario.

AI summary
Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) or network component may select a measurement window type corresponding to the positioning reference signal (PRS) processing window (PPW) or a measurement gap (MG) for measurement processing of each instance of a positioning frequency layer (PFL) for a positioning session of the UE based on one or more selection criteria.
