Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spatial filtering techniques are implemented for resource selection in FR2, then connectivity and reliability are improved, but device complexity increases
Solution Approach 1:
The patent performs monitoring and spatial filter selection in advance before the actual transmission operation. The first device monitors reference signals from the second device using multiple spatial filters, selects the best spatial filter based on monitoring results, and prepares the transmission configuration beforehand. This preliminary action ensures reliable connectivity while managing complexity by organizing the complex spatial filtering process into structured pre-computation steps.
Solution Approach 2:
The patent divides the spatial filtering process into distinct segments: monitoring phase using first spatial filter, resource selection phase, and transmission phase using second spatial filter. By segmenting the complex spatial filtering operation into manageable phases with clear boundaries and objectives, the system achieves high reliability through thorough spatial filter evaluation while keeping device complexity manageable through structured process organization.
2Measurement precision
If monitoring is performed within first time resource based on first spatial filter, then resource selection accuracy is improved, but time resource consumption increases
Solution Approach 1:
The patent performs monitoring within a specific first time resource window, which may be shorter than the full transmission timeline. By concentrating monitoring efforts into a dedicated partial time window rather than continuous monitoring, the system achieves accurate resource selection based on spatial filter performance while limiting time resource consumption to necessary monitoring duration only.
3Reliability
If resource selection procedure uses monitoring results, then transmission reliability is improved, but processing complexity increases
Solution Approach 1:
The patent incorporates monitoring results as feedback into the resource selection procedure. The first device monitors reference signals, evaluates the quality of different spatial filters based on monitoring measurements, and uses this feedback information to select the optimal spatial filter for transmission. This feedback mechanism ensures transmission reliability by base(d on actual channel conditions while managing processing complexity through systematic evaluation criteria.

AI summary
An operation method of a first device 100 in wireless communication system is proposed. The method may include: performing monitoring within a first time resource based on a first spatial filter; selecting a first resource based on a resource selection procedure for a transmission operation; and performing the transmission operation, based on the first resource and a second spatial filter, wherein whether a result of the monitoring is used in the resource selection procedure may be determined based on whether the first spatial filter covers the second spatial filter.
