Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple gap configurations are supported for different terminal operations, then terminal operation efficiency is improved, but system complexity increases
Solution Approach 1:
The patent segments gap configuration into multiple independent types (first gap configuration information for subframe-based gaps, second gap configuration information for slot-based gaps). Each gap type can be independently configured and activated based on specific terminal operation requirements, allowing efficient multi-purpose operation without requiring a completely new configuration system.
Solution Approach 2:
The patent implements dynamic gap configuration where the terminal can adaptively select and switch between different gap types (subframe-based or slot-based) according to real-time operational needs. The RRCReconfiguration message enables dynamic updates to gap parameters, allowing the system to optimize terminal performance across varying operational conditions without fixed rigid structures.
2Adaptability or versatility
If gap configuration is based on multiple information sources (SystemInformationBlock1 and RRCReconfiguration), then configuration flexibility is improved, but processing complexity increases
Solution Approach 1:
The patent employs preliminary configuration through SystemInformationBlock1 which provides default gap configuration information before the terminal enters specific operational modes. This pre-configuration reduces the processing burden during runtime by establishing baseline parameters that can be selectively overridden or refined by subsequent RRCReconfiguration messages, rather than requiring complete configuration processing from scratch each time.
Solution Approach 2:
The patent introduces an intermediary configuration mechanism where RRCReconfiguration acts as a mediator between the static SystemInformationBlock1 and the dynamic terminal operations. The RRCReconfiguration selectively updates only the necessary gap parameters based on current operational requirements, filtering and translating complex configuration needs into specific actionable parameters without requiring the terminal to process all possible configuration options simultaneously.
Data Source
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.
