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 operation, and power control is not adequately addressed in existing technologies.
Innovation Solution
A method and apparatus for configuring gaps in terminals, including determining a first subframe or slot of a gap based on SystemInformationBlock1 and RRCReconfiguration, and using gap information to manage uplink and downlink slots according to subcarrier spacing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple types of gaps are configured for terminal operations (measurement, MUSIM, power control), then terminal operation flexibility and performance are improved, but system complexity and configuration difficulty increase
Solution Approach 1:
The patent segments gap configuration into multiple independent gap types (measurement gap, MUSIM gap, power control gap), each with specific parameters and purposes. This segmentation allows the system to provide diverse gap functions while managing complexity through structured organization of gap parameters and activation conditions for each gap type
Solution Approach 2:
The patent creates a universal gap configuration framework that can accommodate multiple gap types through a common configuration structure. The base station can configure and activate different gap types using a unified RRC message mechanism, allowing one system to serve multiple terminal operation needs (measurement, MUSIM, power control) simultaneously
2Manufacturing precision
If gap configuration parameters are determined based on multiple information sources (SystemInformationBlock1, RRCReconfiguration, tdd-UL-downlink-ConfigurationCommon), then gap configuration accuracy is improved, but information processing complexity increases
Solution Approach 1:
The patent uses SystemInformationBlock1 to pre-configure basic gap parameters before RRC connection establishment. This preliminary configuration provides a foundation that reduces the processing complexity during later RRCReconfiguration stages, as basic parameters are already established and only need refinement rather than complete configuration
Solution Approach 2:
The patent enables dynamic gap configuration where parameters can be adjusted at different stages (initial configuration in SystemInformationBlock1, refinement in RRCReconfiguration, and further adjustment based on tdd-UL-downlink-ConfigurationCommon). This dynamic approach allows the system to adapt gap configurations to changing conditions while maintaining accuracy through multi-stage parameter determination

AI summary
A method and apparatus for Method and Apparatus for activating gaps is provided. The method includes receiving a RRCReconfiguration, configuring a one or more gaps based on the one or more gap configuration information, triggering a first message, triggering a Scheduling Request (SR) if a Uplink Shared Channel resource is available and the UL-SCH resource does not accommodate the first message and a MAC subheader, transmitting a first MAC PDU, receiving a second MAC PDU and activating a gap of the one or more gaps based on the second information in the second message.
