Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G communication systems, there is a need for efficient measurement performance by User Equipment (UE) in wireless environments where network entities operate in different beam modes, requiring accurate information on reference signal transmission schemes to ensure proper channel state recognition and measurement reporting.
Innovation Solution
The apparatus and method involve a UE and a Transmission and Reception Point (TRP) that exchange reference signal configurations, including information on beam sweeping modes and measurement gap durations, allowing the UE to receive and measure reference signals effectively across various beam modes and frequency bands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beam sweeping is used for reference signal transmission in 5G networks, then coverage and signal reliability are improved, but measurement complexity and time consumption increase
Solution Approach 1:
The network entity pre-configures the UE with reference signal configuration information including beam sweeping patterns and measurement gap settings before actual measurement. This preliminary configuration allows the UE to efficiently perform measurements during beam sweeping without real-time negotiation, reducing measurement time while maintaining reliability
Solution Approach 2:
The patent implements dynamic measurement gap configuration where the measurement gap duration and timing are adaptively adjusted based on the beam sweeping pattern and service requirements. This dynamic adjustment optimizes the trade-off between measurement accuracy and time consumption in different operational scenarios
2Adaptability or versatility
If multiple beam modes are supported for different network entities, then system adaptability is improved, but measurement accuracy and channel state recognition deteriorate
Solution Approach 1:
The patent applies different measurement configurations and reference signal settings tailored to each beam mode and network entity type. The UE receives specific measurement gaps and reference signal configurations adapted to the local characteristics of each TRP or gNB, enabling accurate channel state recognition despite diverse beam modes in the network
Solution Approach 2:
The measurement process is segmented into different measurement gaps corresponding to different beam modes and network entities. Each measurement gap is specifically configured for measuring reference signals from particular TRPs or gNBs operating in specific beam modes, allowing precise measurement of each segment without interference from other beam modes
