Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for efficient operation of wireless terminals in diverse scenarios, such as measurement gaps, MUSIM operations, and transmission power control, is not adequately addressed in existing 5G communication systems, necessitating improved gap configuration and request mechanisms.
Innovation Solution
A method for a terminal in a mobile communication system involves receiving RRCReconfiguration messages to establish and manage multiple gap configurations, initiate RRC re-establishment procedures, and release gap configurations at specific times, enabling dynamic gap management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple gap configurations are established for diverse terminal operations (measurement, MUSIM, power control), then the adaptability and operational efficiency of the terminal is improved, but the device complexity and configuration management burden increases
Solution Approach 1:
The patent segments gap configurations into multiple independent configurations (first gap configuration, second gap configuration, etc.), each with distinct parameters and purposes. This allows the terminal to manage different gap types separately, reducing the complexity of managing a single monolithic gap configuration while maintaining high adaptability for diverse operations such as measurement, MUSIM, and power control.
Solution Approach 2:
The patent implements dynamic gap configuration management where the terminal can establish, modify, and release gap configurations based on operational needs. The RRCReconfiguration messages enable dynamic updates to gap parameters, and the terminal can initiate RRC re-establishment procedures to adapt gap configurations in real-time, transforming static gap management into a dynamic system that responds to changing operational requirements.
2Speed
If gap configurations are released at specific points in time, then the system responsiveness and operational efficiency is improved, but the time management complexity and coordination overhead increases
Solution Approach 1:
The patent employs preliminary action by establishing gap configurations in advance through RRCReconfiguration messages before they are needed for specific operations. The terminal receives and processes configuration updates proactively, preparing gap parameters ahead of time. This allows the system to respond quickly when gaps are needed without experiencing delays in configuration setup, effectively preempting time-critical operations.
Solution Approach 2:
The patent implements feedback mechanisms where the terminal monitors operational conditions and provides feedback to trigger gap configuration releases at appropriate times. The RRC re-establishment procedure serves as a feedback loop that allows the terminal to report its operational state and receive updated gap configurations, enabling timely release and reconfiguration of gaps based on actual system needs rather than fixed schedules.

AI summary
A method and Apparatus for configuring gap request and gaps is provided. The method includes receiving from a base station a first RRCReconfiguration, receiving a second RRCReconfiguration, the second RRCReconfiguration includes a first gap configuration and a second gap configuration, establishing by the terminal a first gap or a second gap, Initiating RRC re-establishment procedure, releasing the first gap request configuration at a first point of time, and releasing the first gap configuration and the second gap configuration at a second point of time.
