Measurement Gap Pattern Configuration for 5G UE
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently configuring and managing measurement gap (MG) patterns, particularly in next-generation (5G) networks, which affect the performance of user equipment (UE) in diverse operating modes and frequency ranges.
Innovation Solution
The proposed solution involves configuring UE to use specific MG patterns by determining the frequency range of the serving cell and availability of measurement object configurations. This includes setting measurement gap repetition periodicity (MGRP) and measurement gap length (MGL) values, and generating capability reports based on the mode of operation.

Engineering Contradiction Analysis
1Measurement precision
If measurement gap patterns are configured for diverse frequency ranges and operating modes, then measurement coverage and accuracy are improved, but device complexity and configuration management difficulty increase
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting measurement gap patterns based on frequency range and operating mode. The system selects different MGRP (measurement gap repetition periodicity) and MGL (measurement gap length) values according to the specific FR1 or FR2 scenario, enabling optimized signal measurements without requiring complex manual configuration for each case
Solution Approach 2:
The patent implements dynamics by making the MG pattern configuration adaptive rather than static. The UE automatically determines the appropriate MG pattern based on the serving cell frequency range and available measurement object configurations, allowing the system to dynamically adjust measurement parameters to match current operating conditions
2Reliability
If mandatory MG patterns are implemented for all UEs, then measurement consistency across devices is improved, but adaptability to specific operating modes deteriorates
Solution Approach 1:
The patent applies local quality by providing different MG pattern characteristics for different operating modes and frequency ranges. Instead of a single uniform pattern, the system configures specific MGRP and MGL values tailored to each scenario (e.g., shorter gaps for FR2, different periodicity for dual connectivity modes), ensuring each local context receives optimized measurement parameters
Solution Approach 2:
The patent segments the MG pattern configuration into multiple discrete patterns suitable for different operating modes. The system divides the configuration space into distinct categories (FR1-specific, FR2-specific, dual connectivity modes) and assigns appropriate patterns to each segment, maintaining consistency within each segment while allowing variation across segments

AI summary
A user equipment (UE) device is configured for performing a signal measurement for wireless communication in a new radio (NR) network. The UE is configured to determine a frequency range (FR) of a serving cell configured to send a signal that is measured by the UE using a signal measurement. The UE configures a measurement gap (MG) pattern to perform the signal measurement. Configuring the measurement gap includes determining that the frequency range of the serving cell includes frequencies of a second frequency range (FR2), determining that a measurement object (MO) configuration for the FR2 is available, setting a measurement gap repetition periodicity (MGRP) value for the signal measurement, and setting a measurement gap length (MGL) value for the signal measurement. The UE performs a signal measurement using the MGRP value and the MGL value.
