Terminal Gap Configuration for Flexible 5G Slot Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The need to efficiently configure various gaps in wireless mobile communication systems for terminals to support diverse operations such as measurement, MUSIM, and transmission power control is emerging with the introduction of 5G systems, which require advanced techniques like beamforming and massive MIMO to mitigate propagation loss.
Innovation Solution
A method and apparatus for configuring gaps in terminals, where the terminal receives SystemInformationBlock1 and RRCReconfiguration messages to determine gap configurations based on first and second gap configuration information, using tdd-UL-downlink-ConfigurationCommon to set slots for gap initiation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple gap configurations are implemented for different terminal operations, then terminal operation flexibility and performance are enhanced, but system complexity and configuration difficulty increase
Solution Approach 1:
The patent segments gap configuration into multiple independent configurations (first gap configuration information and second gap configuration information), each serving different terminal operations. This allows the system to manage complexity by dividing the overall gap management into distinct, manageable segments rather than handling all operations with a single monolithic configuration system.
Solution Approach 2:
The base station implements a universal gap configuration mechanism that can serve multiple terminal operation types (measurement, MUSIM, transmission power control) through a unified configuration framework. The system uses common configuration structures (gap configuration information, TDD-UL-DL-ConfigurationCommon) that can be adapted to different operational needs, reducing overall system complexity while maintaining versatility.
2Reliability
If gap configurations are aligned with specific system requirements using multiple configuration information, then terminal performance is enhanced, but information processing overhead increases
Solution Approach 1:
The patent extracts essential gap configuration parameters into dedicated configuration information structures (first gap configuration information, second gap configuration information). By separating the critical configuration elements from the overall system messages, the terminal can efficiently process only the necessary gap-related information without handling the complete system message set, thereby reducing information processing overhead while maintaining operational reliability.
Solution Approach 2:
The base station performs preliminary configuration by pre-defining gap configuration information and associating it with specific terminal operations before actual terminal operations begin. This preliminary setup includes pre-configuring TDD-UL-DL-ConfigurationCommon with appropriate slot patterns, allowing the terminal to quickly reference and apply pre-validated configurations without performing complex real-time calculations, thus reducing processing overhead.

AI summary
A method and apparatus for configuring various gaps for a terminal is provided. The method includes receiving from a base station a SystemInformationBlock1, receiving a RRCReconfiguration, configuring by the terminal at least a gap, the gap is configured based on the first gap configuration information. If the gap starts at a first subframe, the first subframe is determined based on the first gap configuration information and if the gap is configured based on the second gap configuration information, the gap starts at a first slot, the first slot is determined based on the tdd-UL-downlink-ConfigurationCommon, the first slot is the first static uplink slot from a second subframe, the second subframe is determined based on the second gap configuration information.
