Standalone PDCP Delay Measurement Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current RRC reporting methods in wireless communication systems, particularly for Minimization of Drive Tests (MDT), do not allow for separate reporting of uplink packet data convergence protocol (PDCP) delay measurements, which are essential for network optimization, as they are linked to existing measurement configurations identifying specific cells or frequencies, limiting the ability to obtain dedicated measurement results.
Innovation Solution
A new measurement configuration and reporting model are introduced, where a UE-specific measurement object is created for PDCP layer measurements, independent of existing cell or frequency configurations, allowing for standalone uplink PDCP packet delay measurements to be reported, enhancing MDT reporting capabilities and network optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If uplink PDCP delay measurements are linked to existing measurement configurations identifying specific cells or frequencies, then the measurement configuration can be associated with specific network locations, but the ability to obtain dedicated measurement results independent of cell/frequency configurations is limited
Solution Approach 1:
The patent segments the measurement configuration by introducing a separate measurement object for uplink PDCP delay measurements that is independent of cell-specific or frequency-specific measurement objects. This allows the uplink delay measurement to be configured and reported separately from downlink measurements tied to specific cells or frequencies, enabling dedicated measurement results without requiring complex associations between multiple measurement types.
2Adaptability or versatility
If a UE-specific measurement object is created for PDCP layer measurements independent of cell or frequency configurations, then separate reporting of PDCP delay measurements is enabled, but the existing measurement configuration structure must be extended
Solution Approach 1:
The patent extracts the uplink PDCP delay measurement functionality from the existing cell-specific or frequency-specific measurement configuration structure. By creating a separate measurement object specifically for uplink delay measurements, the patent enables independent configuration and reporting of this measurement type without being constrained by the existing measurement configuration structure, thus enhancing adaptability while managing complexity through separation of concerns.
