Dynamic Measurement Gap Configuration for 5G NR Throughput
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in measurement gap configuration, leading to redundant network reconfigurations and throughput degradation due to periodic measurement gaps, which are not dynamically adaptable to the needs of user equipment (UE) in 5G New Radio (NR) environments.
Innovation Solution
The introduction of semi-persistent (SP) and aperiodic (AP) measurement gap configurations, where UE devices indicate support for these configurations to the wireless station, allowing for pre-configuration and dynamic activation/deactivation of measurement gaps based on specific frequency ranges, carriers, or bandwidth parts, reducing unnecessary measurements and improving network efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If periodic measurement gap configuration is used, then measurement operations can be performed regularly, but network throughput degrades due to redundant measurement gaps and reconfigurations
Solution Approach 1:
The patent implements dynamic measurement gap configuration where the network can activate or deactivate measurement gaps based on real-time conditions. The UE receives RRC messages to dynamically activate/deactivate SP-MG configurations, allowing the system to adapt measurement operations to actual network needs rather than following rigid periodic schedules, thus resolving the contradiction between reliable measurements and network throughput.
Solution Approach 2:
The patent changes the parameter of measurement gap configuration from fixed periodic to semi-persistent with dynamic activation. By introducing activation/deactivation states and allowing parameter adjustments based on frequency ranges, carriers, and bandwidth parts, the system optimizes the balance between measurement reliability and network throughput efficiency.
2Adaptability or versatility
If semi-persistent measurement gap configuration is implemented, then measurement flexibility improves, but device complexity increases due to additional configuration management
Solution Approach 1:
The patent segments the measurement gap configuration into multiple independent SP-MG configurations, each associated with specific frequency ranges, carriers, or bandwidth parts. This segmentation allows the UE to manage measurements on different frequencies independently, improving flexibility while organizing complexity into manageable segments rather than a monolithic configuration.
Solution Approach 2:
The patent implements pre-configuration of SP-MG parameters before actual measurement operations. The network provides RRC configuration messages in advance that define measurement gap parameters, which are then activated or deactivated as needed. This preliminary action reduces real-time complexity by preparing configurations beforehand.
3Productivity
If dynamic activation and deactivation of measurement gaps is performed, then network efficiency improves, but signaling overhead increases due to additional activation/deactivation messages
Solution Approach 1:
The patent designs the activation/deactivation signaling to serve multiple purposes. The same RRC message structure is used for both activation and deactivation operations, and the configuration messages simultaneously define parameters for multiple frequency ranges and carriers. This multi-functionality reduces the need for separate dedicated signaling for each operation type.

AI summary
Aspects herein relate to wireless devices, circuits, and methods for indicating, by a wireless device, to a wireless station, an ability to support semi-persistent (SP) measurement gap (MG) configuration; receiving, from the wireless station, a SP MG configuration; receiving, from the wireless station, a message to activate the SP MG configuration; performing, in response to receiving the message to activate the SP MG configuration, a target carrier frequency measurement, wherein the target carrier frequency measurement is performed in accordance with the activated SP MG configuration; receiving from the wireless station, a message to deactivate the SP MG configuration; and discontinuing, in response to receiving the message to deactivate the SP MG configuration, the performance of the target carrier frequency measurement. In other aspects, the wireless device may indicate, to the wireless station, an ability to support aperiodic (AP) MG configuration, which does not require explicit deactivation by the wireless station.
