Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies face interference and control challenges due to the simultaneous transmission of discovery and control signals at the same frequency during device discovery and ranging processes, leading to inefficient signal reception and potential signal loss.
Innovation Solution
Transceiving discovery and control signals at different frequencies, allowing for separate control and reduction of interference between signals, thereby ensuring smooth device discovery and ranging processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If discovery signals and control signals are transmitted at the same frequency, then the system complexity is reduced and ease of operation is improved, but signal interference increases and reception reliability deteriorates
Solution Approach 1:
The patent divides the transmission medium into separate frequency channels, assigning discovery signals to one frequency and control signals to another frequency. This segmentation prevents signal interference while maintaining operational simplicity, as each signal type has its dedicated transmission path without needing complex time-division or priority-based scheduling mechanisms.
2Device complexity
If discovery signals and control signals are transmitted at the same frequency, then the device complexity is reduced, but signal interference increases leading to control challenges
Solution Approach 1:
The patent resolves the contradiction by transitioning from a single-dimensional (single frequency) transmission approach to a multi-dimensional (multiple frequencies) approach. By adding the frequency dimension as a separation mechanism, the system can transmit multiple signal types simultaneously without interference, avoiding the need for complex time-division multiplexing or signal prioritization logic.
3Reliability
If discovery signals and control signals are transmitted at different frequencies, then signal interference is reduced and reception reliability is improved, but device complexity increases
Solution Approach 1:
The patent changes the frequency parameter of signal transmission to resolve interference issues. By assigning different frequency values to discovery signals and control signals, the system achieves reliable simultaneous transmission without requiring complex interference management protocols, signal prioritization mechanisms, or advanced reception algorithms.
