Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If analog beamforming is applied for signal transmission and reception, then signal transmission efficiency is improved, but RRM measurement and reporting complexity increases
Solution Approach 1:
The patent segments the RRM measurement process by introducing specific measurement timing configurations that align with analog beam switching periods. Terminals perform measurements only during designated measurement symbols when specific beams are active, dividing the continuous measurement task into discrete, manageable segments that reduce overall complexity while maintaining transmission efficiency.
Solution Approach 2:
The patent implements dynamic measurement configurations where measurement timing, bandwidth, and resource allocation adapt based on analog beam switching patterns. The base station dynamically configures measurement parameters according to current beam states, allowing the system to maintain high transmission efficiency while adjusting measurement complexity to match actual operational conditions.
2Measurement precision
If RRM measurement is performed frequently to maintain accuracy, then measurement precision is improved, but system overhead and latency increase
Solution Approach 1:
The patent implements periodic measurement opportunities synchronized with analog beam switching cycles. Instead of continuous measurement, terminals perform RRM measurements at regular intervals defined by measurement periods that align with beam switching patterns. This periodic approach maintains measurement accuracy by capturing beam state information at relevant intervals while significantly reducing measurement overhead and reporting latency compared to continuous measurement.
Solution Approach 2:
The patent configures measurement resources and timing in advance based on predicted beam switching patterns. The base station pre-allocates measurement symbols and resources before beam switches occur, allowing terminals to prepare measurement configurations ahead of time. This preliminary action reduces latency by eliminating real-time configuration delays while maintaining measurement precision through pre-planned measurement opportunities.
