Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If reference signals for positioning are transmitted frequently to improve positioning accuracy, then positioning precision is improved, but device energy consumption increases
Solution Approach 1:
The patent implements periodic reference signal transmission where the first device transmits positioning reference signals at specific time intervals rather than continuously. The second device receives these periodic signals and uses them for positioning calculations, achieving accurate location determination while significantly reducing energy consumption compared to continuous transmission modes.
2Reliability
If multiple reference signals are transmitted to improve positioning reliability, then positioning reliability is improved, but transmission time increases
Solution Approach 1:
The patent employs preliminary action by having the first device transmit multiple positioning reference signals in advance before the actual positioning measurement is needed. The second device receives and processes these pre-transmitted signals, allowing positioning calculations to be performed without delaying the actual positioning operation, thus improving reliability without increasing critical transmission time.
3Measurement precision
If reference signal resources are allocated densely to improve positioning precision, then positioning precision is improved, but resource allocation efficiency decreases
Solution Approach 1:
The patent applies local quality by allocating reference signal resources selectively based on local positioning requirements. The first device transmits reference signals on specific time-frequency resources that are optimized for positioning purposes, while other resources remain available for data transmission. This localized resource allocation achieves high positioning precision without compromising overall system resource allocation efficiency.

AI summary
Proposed are a method for a first device to perform wireless communication and a device supporting same. For example, the first device may obtain information related to a reference signal (RS) for positioning, including information related to an RS resource, and the first device may transmit (i) a first RS for the positioning and (ii) information related to a time allowed for transmission of a second RS for the positioning, and the first device may receive the second RS for the positioning.
