Wireless Measurement Gap Configuration for Concurrent 5G/6G Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication networks face challenges in handling measurement gaps, particularly in 5G networks, due to limitations in supporting concurrent measurement gaps, preconfigured gaps, and network-controlled small gaps, leading to restricted UE and network apparatus implementation.
Innovation Solution
The proposed methods and systems enable the network apparatus to handle measurement gaps by receiving UE capability information, modifying or releasing existing gaps, and configuring enhanced measurement gaps in dual connectivity, including per-UE and per-FR gaps, with the ability to set default gap priorities between 2 and 15, allowing simultaneous support of various gap configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the network apparatus configures multiple measurement gap types (concurrent gaps, preconfigured gaps, NCSG) simultaneously, then the measurement capability and flexibility are improved, but the device complexity and implementation difficulty increase
Solution Approach 1:
The patent segments the measurement gap configuration into distinct types (concurrent gaps, preconfigured gaps, NCSG) with separate configuration procedures and capability indicators. Each gap type can be independently configured and managed, allowing the network apparatus to handle multiple gap types through structured, modular configuration messages that reduce overall system complexity while maintaining versatility.
Solution Approach 2:
The network apparatus implements a universal gap configuration mechanism that can handle multiple gap types through a unified RRC configuration framework. The system uses a common configuration structure with type-specific parameters, enabling single apparatus to perform multiple gap configuration functions simultaneously, thus improving adaptability without proportionally increasing complexity.
2Measurement precision
If the UE supports multiple measurement gap enhancement features simultaneously, then the measurement precision and coverage are improved, but the ease of operation and configuration difficulty increase
Solution Approach 1:
The patent implements preliminary capability indication where the UE reports its supported measurement gap enhancement features (concurrent gaps, preconfigured gaps, NCSG) to the network apparatus before actual configuration. This preliminary action allows the network to prepare appropriate configuration messages in advance, reducing operational complexity during actual measurement setup while enabling precise multi-feature support.
Solution Approach 2:
The system employs feedback mechanisms where the UE provides capability information about supported measurement gap features, and the network apparatus uses this feedback to configure appropriate gap types. This bidirectional feedback loop ensures that the UE receives configurations matching its capabilities, simplifying operation while achieving high measurement precision through appropriate feature combinations.
3Reliability
If the network apparatus configures gap priority for concurrent gaps, then the collision conflict resolution is improved, but the device complexity increases
Solution Approach 1:
The patent applies local quality by assigning gap priority specifically to concurrent gaps where collision resolution is needed, rather than uniformly to all gap types. The priority parameter is localized to the concurrent gap configuration context, providing reliable collision resolution only where necessary (when multiple gaps operate simultaneously) while avoiding unnecessary complexity in configurations where priority management is not required.
