Signal Transmission Control for Interference Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Additional nodes or devices in communication systems, such as repeaters or RISs, continuously process and transmit RF signals, including noise and interference, leading to interference for mobile terminals and base stations, and increase overall power consumption.
Innovation Solution
A method and apparatus for controlling signal transmission, where a first unit is started or closed based on information received from the network device or detection of signals, avoiding the processing and transmission of unnecessary signals, thereby reducing interference and energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional nodes (repeaters/RISs) continuously process and transmit RF signals, then signal coverage and reliability are improved, but interference to mobile terminals and base stations increases
Solution Approach 1:
The patent applies dynamics by enabling additional nodes to switch between active and dormant states based on detected signal conditions. The node monitors reference signals from network devices or terminals and dynamically adjusts its operation mode, transitioning from continuous processing to selective processing only when needed, thus reducing interference during idle periods while maintaining coverage when required
Solution Approach 2:
The patent changes the operational parameter of additional nodes from continuous processing to conditional processing based on signal detection results. By monitoring parameters such as reference signal received power (RSRP) or signal quality, the node adjusts its processing activity level, enabling it to operate only when signal conditions warrant, thereby reducing unnecessary interference
2Reliability
If additional nodes continuously process and transmit RF signals, then signal transmission reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic action by having additional nodes monitor signal conditions at periodic intervals and adjust their processing activity accordingly. Instead of continuous operation, the node engages in periodic detection cycles followed by dormant periods, processing signals only when detected conditions indicate necessity, thus reducing overall power consumption while maintaining transmission reliability
Solution Approach 2:
The patent applies dynamics by enabling additional nodes to switch between active and dormant states based on detected signal conditions. The node monitors reference signals from network devices or terminals and dynamically adjusts its operation mode, transitioning from continuous processing to selective processing only when needed, thus reducing interference during idle periods while maintaining coverage when required
