Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication networks face challenges in efficiently performing inter-frequency positioning measurements due to restricted measurement patterns and heterogeneous network deployments, which lead to increased complexity and reduced accuracy in UE measurements.

The method involves determining optimal switching points and inter-group offsets for measurement groups, allowing UEs to efficiently switch between measurement groups while minimizing unused measurement occasions and optimizing resource utilization, by configuring nodes based on UE capability information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurements are performed according to restricted measurement patterns in heterogeneous networks, then measurement accuracy is improved, but device complexity increases
Solution Approach 1:
The patent divides measurements into multiple measurement groups (first measurement group and second measurement group) with different measurement patterns. The UE applies different measurement patterns to different groups of cells, allowing restricted measurements to be performed on specific groups while using relaxed patterns on others, thereby improving measurement accuracy where needed without unnecessarily increasing overall device complexity.
Solution Approach 2:
The patent introduces dynamic switching between different measurement patterns based on network configuration and UE capability. The network can configure the UE to switch between restricted measurement patterns and relaxed measurement patterns depending on the measurement group and current network conditions, allowing the system to adapt measurement complexity to actual requirements rather than applying uniform high complexity to all measurements.
2Productivity
If multiple measurement groups are performed with different patterns, then measurement efficiency is improved, but the number of unused measurement occasions increases
Solution Approach 1:
The patent merges measurement opportunities across different measurement groups by carefully coordinating the measurement patterns. The network configures switching points and inter-group offsets to ensure that measurement occasions from different groups are utilized efficiently, combining restricted measurement occasions with relaxed measurement occasions to minimize unused measurement opportunities while maintaining the benefits of multiple measurement groups.
3Productivity
If switching points are optimized for measurement groups, then resource utilization is improved, but configuration complexity increases
Solution Approach 1:
The patent creates a universal configuration framework where the network configures multiple measurement groups with different patterns using a standardized procedure. The switching points and inter-group offsets are configured through a unified mechanism that can handle multiple measurement groups simultaneously, allowing the same configuration approach to be applied universally across different scenarios rather than requiring custom configurations for each case.

AI summary
A measuring node (700) in a wireless network (100) sets switching points for a plurality of measurement groups, performs measurements of signals transmitted from one or more cells corresponding to a group, and switches, at each switching point, from performing measurements according to one measurement group to performing measurements according to the next measurement group. The signals are transmitted by the cells in measurement occasions that repeat in a pattern. A switching point is a time by which the measuring node (700) node is expected to complete, at least in part, measurements of the one group and be ready to proceed with measurements of the next group. A configuring node (600) sends assistance data to the measuring node (700) to enable the measuring node (700) to determine the switching points for the measurement groups.
