Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G wireless communication systems face challenges in accurately configuring and activating measurement gaps for user equipment (UE) devices, particularly in managing multiple concurrent measurement gaps and pre-configured measurement gaps, which affect the accuracy of timing errors in positioning methods and require enhanced reporting mechanisms.
Innovation Solution
The system configures multiple concurrent measurement gaps independently within a common time period, allowing for pre-configured measurement gaps that can be activated autonomously by the network and UE, enabling accurate timing error estimation and compensation, and supports advanced positioning techniques through specific Information Element formats and reporting formats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple concurrent measurement gaps are configured independently, then measurement accuracy and positioning precision are improved, but device complexity and configuration management difficulty increase
Solution Approach 1:
The patent divides measurement gap configuration into multiple independent concurrent measurement gaps, each with separate timing parameters (O_offset, duration, periodicity). This segmentation allows the system to perform multiple types of measurements simultaneously with dedicated time resources, improving measurement precision while maintaining manageable complexity through standardized configuration structures.
Solution Approach 2:
The patent implements pre-configuration of measurement gap parameters before actual measurement operations. The network device pre-configures multiple measurement gap patterns with defined timing relationships, and the UE device stores these configurations for activation. This preliminary action reduces real-time configuration complexity and enables rapid switching between different measurement scenarios.
2Reliability
If pre-configured measurement gaps with activation indications are implemented, then network control and measurement timing accuracy are improved, but signaling overhead and configuration management increase
Solution Approach 1:
The patent extracts the measurement gap activation control from continuous configuration signaling and implements it through dedicated activation indication mechanisms. The network device sends specific activation indications (e.g., MAC CE or DCI formats) to trigger pre-configured measurement gaps only when needed. This extraction reduces unnecessary signaling overhead while maintaining reliable network control over measurement timing.
Solution Approach 2:
The patent enables the UE device to autonomously activate and manage measurement gaps based on pre-configured parameters and received activation indications. Once the network provides the activation trigger, the UE device self-manages the measurement gap execution, timing, and reporting without requiring continuous network intervention. This self-service approach reduces signaling overhead while maintaining measurement reliability.
3Productivity
If multiple measurement gaps operate concurrently during the same time period, then measurement efficiency and positioning performance are improved, but resource scheduling complexity and interference management increase
Solution Approach 1:
The patent introduces multiple dimensional parameters for measurement gap configuration, including different time offsets (O_offset), durations, periodicities, and frequency associations. By operating measurement gaps in multiple time and frequency dimensions simultaneously, the system achieves high measurement efficiency while managing resource scheduling complexity through structured dimensional separation. Each measurement gap occupies a unique combination of temporal and spectral resources.
Solution Approach 2:
The patent implements dynamic measurement gap configurations where parameters such as activation/deactivation, timing offsets, and duration can be adjusted based on network conditions and measurement requirements. The network device can dynamically modify which measurement gaps are active and their specific parameters, enabling flexible resource scheduling that adapts to changing conditions while maintaining concurrent operation capability.

AI summary
This disclosure describes systems, methods, and devices related to measurement gaps. A user equipment (UE) device may identify a configuration message, received from a 5G network device prior to switching from an active bandwidth part (BWP), for a pre-configured measurement gap during which the UE device is to perform an both gapless and gap-based frequency measurements, the configuration message indicating that the pre-configured measurement gap requires activation; identify an activation of the pre-configured measurement gap; and measure a reference signal during the pre-configured measurement gap.
