Ranging Time Window and Gap Configuration for 5G UE
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3GPP 5G systems lack detailed configurations for the ranging period of a User Equipment (UE) in cellular networks, which is essential for enabling ranging-based services directly between UEs.
Innovation Solution
A network node transmits configuration information to a UE regarding a time period for a ranging measurement operation, including a ranging time window and a ranging time gap, allowing the UE to execute ranging measurements and RF switch procedures accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If ranging measurement operations are configured without dedicated time windows and gaps, then UE can continuously perform communication, but ranging-based services cannot be reliably executed due to lack of time allocation
Solution Approach 1:
The patent segments the time period into distinct ranging time windows and ranging time gaps. The ranging time window is dedicated to ranging measurement operations, while the ranging time gap is allocated for RF switch procedures. This segmentation ensures that ranging-based services have dedicated time allocation without interfering with legacy communication opportunities, thereby resolving the contradiction between service execution and time loss.
2Ease of operation
If UE performs RF switch procedures during communication time, then RF switching can be completed, but communication efficiency decreases due to overlapping operations
Solution Approach 1:
The patent separates RF switch procedures into a dedicated ranging time gap that does not overlap with ranging time windows or legacy communication opportunities. This ensures that RF switching can be completed without interfering with communication efficiency, as the RF switch procedure has its own dedicated time slot.
Solution Approach 2:
The network node configures the ranging time gap in advance, allowing the UE to perform RF switch procedures before actual ranging measurements are needed. This preliminary configuration ensures that RF switching is ready when required without causing delays or efficiency losses during communication.
3Adaptability or versatility
If ranging time window and gap are not configured, then UE structure remains simple, but ranging-based services cannot avoid overlapping with legacy communication
Solution Approach 1:
The patent designs the ranging time window and ranging time gap configuration to be applicable across different scenarios and UE types. The network node can configure these time periods flexibly to accommodate various ranging-based services while maintaining compatibility with existing legacy communication mechanisms, thereby achieving versatility without excessive complexity.
