Engineering Contradiction Analysis
1Productivity
If reference signal resources are mapped using conventional methods, then the system is simple to implement, but the data rate and spectral efficiency cannot meet 6G requirements
Solution Approach 1:
The patent applies dynamics by making the reference signal mapping configurable and adaptable. The system dynamically selects mapping parameters (number of symbols M, comb size N, sequence list) based on channel conditions and service requirements, allowing the mapping structure to flex between different configurations rather than being fixed
Solution Approach 2:
The patent changes parameters of the reference signal mapping including the number of symbols M, comb size N, and sequence list. By varying these parameters, the system can optimize spectral efficiency and data rate for different 6G scenarios while maintaining a unified mapping framework
2Measurement precision
If more reference signal resources are allocated, then measurement precision and reliability improve, but resource consumption and latency increase
Solution Approach 1:
The patent applies local quality by allocating reference signal resources non-uniformly. Different regions or time slots receive different densities of reference signals based on local channel conditions, mobility requirements, and service priorities, rather than using a uniform distribution throughout the system
Solution Approach 2:
The patent uses partial action by allocating reference signals only where and when needed. The system transmits reference signals with optimized density and positioning, providing sufficient measurement precision for critical functions while avoiding excessive resource allocation that would increase latency and overhead
3Reliability
If reference signal transmission is performed with high density, then connectivity reliability improves, but energy consumption increases
Solution Approach 1:
The patent applies periodic action by transmitting reference signals at optimized intervals and densities rather than continuously at maximum density. The periodic transmission is configured to maintain connectivity reliability for mobile devices while significantly reducing overall energy consumption compared to continuous high-density transmission

AI summary
Proposed are a method by which a first device performs wireless communication, and a device supporting same. For example, the first device may obtain information related to a reference signal (RS), the information including first information related to the number of M symbols, second information related to a comb size of N, and third information related to a sequence list. For example, the first device may transmit a first RS on the basis of the information related to the RS. For example, on the basis of M being less than the number K of candidate symbols available for transmission of the RS within a first slot, RS resources may be mapped to K symbols within the first slot.
